The technical FIELD
The present invention relates to a suspension suitable for use as a component of liquid compositions for processing.
In the manufacture of liquid compositions for processing, the goal is to improve their technical and aesthetic characteristics. One way to improve the aesthetic characteristics of the liquid composition for treatment is giving her a pearl type.
Mother-of-pearl effect can be achieved by incorporating pearlescent agent in the liquid composition for treatment. Pearlescent agents include inorganic materials such as mica, bismuth oxychloride and titanium dioxide, and organic compounds such as metal salts of higher fatty acids, complex glycol esters of fatty acids and alkanolamide fatty acids. The present invention relates only to the use of inorganic pearlescent agents. Pearlescent agent may be purchased in the form of a powder, a suspension agent in a suitable suspendium agent or, in cases where the agent is a crystalline material, it can be obtained in situ.
Composition of detergent and pearlescent dispersions containing pearlescent agents of type complex glycol fatty acid ester, are disclosed in the following and is the source: US 4717501 (in the name of Kao); US 5017305 (in the name of Henkel); US 6210659 (in the name of Henkel); US 6835700 (name Cognis). Liquid compositions for treatment containing pearlescent agents are disclosed in US 6956017 (in the name of the Procter & Gamble). Liquid detergents for washing delicate garments, containing pearlescent agent, are disclosed in EP 520551 B1 (in the name of Unilever).
The present invention relates to a suspension containing inorganic pearlescent agent. The suspension described in WO 2007/111899 A2 (in the name of the Procter & Gamble), uses water as a carrier for pearlescent agent. However, applicants have found that the use of water as a carrier for pearlescent agent only provides up to six weeks of physical stability, after which the pearlescent agent begins to precipitate.
Suspension of inorganic pearlescent agent WO 2007/11189 is prepared using a batch process. A measured quantity of a suspension of inorganic pearlescent agent is then introduced into a continuous process used to obtain liquid compositions for processing. However, as mentioned above, inorganic pearlescent agents tend to settle out of suspension. This deposition creates problems when using continuous method for the preparation of liquid compositions for treatment, because there will be areas in which there may exist resorna pearl or may not be the pearl. One of the potential solutions to such problems may be an increase in the viscosity of suspensions. However, the final products should be of relatively low viscosity, especially at high shear loads, so that they can be transferred or used for processing. Therefore, the components of the liquid composition for processing the suspension should not have too high a viscosity. On the contrary, if the slurry has a low viscosity at low shear stress, particulate materials have a tendency to stand out from the suspension and the storage surface or deposited. This leads to the formation of undesirable non-homogeneous suspension in which the suspension is mother-of-pearl, and some transparent and homogeneous. It is obvious that such suspension will have undesirable effects on the aesthetic characteristics of the finished composition, which may be overly pearl or not pearl. In this case the applicant has found that a simple change in the viscosity of the suspension does not allow sufficiently to eliminate the problems described in this invention.
In addition, inorganic pearlescent agents are insoluble and without appropriate solution behave like wet sand, causing problems in the processing of suspensions. The behavior is similar to the wet sand, Usain is no mixing of the suspension and requires much effort from the equipment, used during blending.
The present invention provides for the suspension and the procedure for the preparation of suspensions, suitable for further processing in the liquid composition for processing. The present invention specifically relates to improved physical stability and technological life time (process lifetime) suspension of inorganic pearlescent agent, thereby improving the manufacturing process and quality improvement liquid composition for processing. The present invention also relates to the use of a combination of solvent and modifier rheology in suspensions of inorganic pearlescent agents to improve the physical stability and technological life time suspension. Applicants have discovered that water is replaced by glycerol or morbity solvent increases the physical stability of the suspension, and the suspension remains physically stable for at least 16 weeks. The present invention also relates to an optimized method of manufacturing a suspension of inorganic pearlescent agent, where the introduction of inorganic pearlescent agent is strictly monitored.
In accordance with the present invention provides for the suspension of the inorganic pearlescent agent suitable for use in the LM is some compositions for the treatment, contains:
a) inorganic pearlescent agent,
b) an organic solvent selected from the group consisting of glycerol, sorbitol and mixtures thereof,

c) adding the rest of the inorganic pearlescent agent.
A DETAILED DESCRIPTION of the INVENTION
In the present invention, the term suspension is used to denote a liquid composition, which is typically liquid at ambient temperature and contains a water-insoluble solid dispersion materials or other solid substances.
Suspension of inorganic pearlescent agent of the present invention is suitable for use as a component of liquid compositions for the treatment, suitable for use in the wash or in the home. The term composition for washing understood as including all the liquid composition used in PR is conducting processing by washing, including cleaning and sleek or conditioning compositions. The term composition for hard surface processing is understood as including all liquid compositions used for treatment of hard surfaces, such as surfaces in the kitchen or in the bathroom, and dining and cooking utensils when washing dishes manually or by automatic devices.
Suspension pearlescent agent in accordance with the present invention for this application contains from 30% to 60% water. However, preferably, it contains no added free water. In those cases, when the slurry contains water, it is preferably present as a component of another ingredient suspension, such as a premix of rheology modifier.
Suspension of inorganic pearlescent agent of the present invention preferably has a viscosity of from 21000 to 65000 centipoise at 0.5 s-1and from 1000 to 3000 centipoise at 20-1. The viscosity can be determined by conventional methods. Viscosity in accordance with the present invention, however, is measured with a rheometer AR 550 company TA Instruments using a spindle of plate steel with a diameter of 40 mm and a gap of 500 μm. The viscosity at high shear rate at 20-1and the viscosity at a low shear rate at 0.5 s-1can be identified by logarithmica is some curve scan shear rate from 0.1 -1up to 25-13 minutes at 21°C.
The suspension according to the present invention preferably has a pH from 7 to 11, more preferably, from 7 to 9, when measured directly in suspension.
The temperature of the slurry during the manufacturing process and during storage, preferably, is below 35°C. In those cases where the rheology modifier is hydrogenated castor oil (HCO), temperature, and more preferably is in the range from 10°C to 30°C. the NSO has a low melting point and will lose activity modifier rheology during melting, causing instability of the suspension.
Pearlescent agents in accordance with the present invention are inorganic crystalline or glassy, solid, transparent or semi-transparent connection, able to reflect and refract the light, creating a pearlescent effect. Typically, pearlescent agents are crystalline particles, insoluble in the composition in which they are included. Preferably, pearlescent agents have the form of thin plates or spheres. Areas in accordance with the present invention should be understood as having in common a spherical shape. Particle size is measured by the greatest diameter of the sphere. The plate cha the TIC two particle size (length and width) of at least 5 times greater than the third dimension (height or thickness). Crystals of other shapes, such as cubic or needle or other crystalline forms, do not show pearlescent effect. Many pearlescent agents such as mica, are natural minerals that have monoclinic crystals. The form seems to affect the stability of the agents. Spherical, even more preferably plate-like agents can be stabilized most successfully.
The mechanism of occurrence of mother-of-pearl effect described R.L.Crombie in International Journal of Cosmetic Science, Vol.19, page 205-214. Light reflected from the pearl plates or spheres arranged essentially parallel to each other at different levels in the composition, creates a sense of depth and brilliance. Some light is reflected pearlescent agent, and the rest of the light passes through the agent. When this light passes through a pearlescent agent, may pass through or be deflected. Reflected refracted light creates different colors, brightness and Shine. The smaller the particle size of the pearlescent agent and their size distribution, the easier they suspendida. However, with decreasing particle size of the pearlescent agent the effectiveness of the agent also decreases. Therefore, preferably, in the present invention pearlescent agent had a particle size of preferably from 5 to 32 micrometers, more preferably from 5 to 2 micrometers.
The suspension of the present invention, preferably contains from 1% to 35%, by weight of the suspension, 100% active substance is an inorganic pearlescent agent. More preferably, the slurry contains from 10% to 30%, more preferably from 10% to 20%, by weight of the suspension, 100% active substance is an inorganic pearlescent agent.
Pearlescent agents of the present invention are inorganic. Inorganic pearlescent agents provide both dynamic and static pearlescent effect. Under the dynamic mother-of-pearl effect means that the composition exhibits a pearlescent effect, when it is in motion. Under static pearlescent effect means that the composition exhibits a pearlescent effect when the composition is fixed.
Inorganic pearlescent agents
Inorganic pearlescent agents include materials selected from the group consisting of mica, mica coated with metal oxide, mica coated with silicon dioxide, mica coated with bismuth oxychloride, bismuth oxychloride, myristoleate, glass, glass coated with metal oxide, guanine, sequin (polyester or metal) and their mixtures.
Suitable mica include Muscovite or hydroxyphthalic potassium-aluminum. Plates of mica, preferably, p is opening a thin layer of metal oxide. Preferred metal oxides are selected from the group consisting of rutile, titanium dioxide, iron oxide(3), tin oxide, aluminum oxide and mixtures thereof.
Pearl effect such pearlescent agents arises from the interference between light rays reflected at angles of specular reflection from the upper and lower surfaces of the layer of metal oxide. The intensity of the coloring agents is reduced with the removal of the angle from the angle of mirror reflection and gives them a pearlescent appearance.
More preferably, the inorganic pearlescent agents are selected from the group consisting of mica and bismuth oxychloride, and mixtures thereof. More preferably, the inorganic pearlescent agents are mica. More preferably, pearlescent agent is a mica coated with metal oxide, more preferably, mica coated with titanium oxide, mica coated with bismuth oxychloride or mica coated with silicon dioxide, and mixtures thereof.
Commercially available suitable inorganic pearlescent agents are delivered by the company Merck under the trade names Iriodin, Biron, Xirona, Timiron Colorona, Dichrona, Candurin and Ronastar. Other commercially available inorganic pearlescent agents supplied by firms BASF (Engelhard, Mearl) under the trademarks Biju, Bi-Lite, Chroma-Lite, Pearl-Glo, Mearlite, and Ekart under the trademarks Prestige Soft Silver and Prestige Silk Silver Star.
Inorganic pearlescent agents, preferably introduced in the form of powder and are used for preparation of the suspension without the need for any additional stages of processing. The method of preparation of the suspension will be described in more detail later.
The system of organic solvent
The system solvent in combination with the rheology modifier is essential to ensure the physical stability of the suspension. Suitable solvents in accordance with this invention are organic solvents selected from the group consisting of glycerol and sorbitol and mixtures thereof. The solvent is typically present in amounts in the range from 10% to 50%, preferably from 20% to 40%, by weight of the suspension.
Glycerin is a colorless and viscous liquid, odorless. It has a sweet taste and low toxicity. Glycerol has three hydroxyl groups, which provides its solubility in water and its hygroscopic nature.
Sorbitol is a sugar alcohols having six hydroxyl groups, which provides its solubility in water and its hygroscopic nature.
Without wanting to be limited by theory, we can note that, as is, there is synergy between the solvent and the modifier rheology. In addition, it is believed that the ICI is EMA, containing these two elements provides greater elasticity in the system. This elasticity is manifested in the fact that the system or the grid is able to recover faster after application of shear load.
The rheology modifier
The suspension according to the present invention contains a rheology modifier. The overall goal of adding such a rheology modifier to the slurry of the present invention is to obtain a suspension, which would be suitable functional and aesthetically attractive taking into account such characteristics of the suspension, as the density, fluidity, physical stability, optical properties and/or performance characteristics of the suspension particles. Thus, the rheology modifier serves to provide suitable rheological characteristics of the slurry and performs this function without making the product any undesirable characteristics, such as unacceptable optical properties or undesirable separation of the phases. Under the rheological characteristics refer to the characteristics of the suspension flow under the application of load and deformation.
Component modifier rheology of suspensions pearlescent agent of the present invention may be characterized as "external" or "internal" modifier rheology. "External" rheology modifier, for the purposes of the present invention is a material the primary function of which is the change in the rheological characteristics of the liquid matrix. Usually, therefore, the external rheology modifier by itself will not provide any significant beneficial effect cleaning cloth or fabric care or any significant beneficial effect solubilization of the ingredient. External rheology modifier, thus, differs from the "internal" modifier rheology, which can also modify the rheology of the matrix, but which is introduced into the liquid product with some additional primary goal. Thus, for example, the preferred internal rheology modifier will anionic surfactants that can be used to modify the rheological properties of a suspension, but which are added to the suspension in the first place as a cleaning ingredient of the finished product.
Modifier rheology of suspensions of the present invention is used to create a liquid matrix suspension pearlescent agent having specific rheological characteristics. The main characteristic is that the matrix must be able to "liquefied shear". Razzhizhayuschiesya shear fluid has a viscosity that decreases with application to fluid shear stress. Therefore clicks the zoom, in the rest state, i.e. when storing or transporting the suspension liquid matrix suspension should have a relatively high viscosity. However, in the case of an application for suspension pearlescent agent, shear loads, such as during pouring, pumping or mixing of the suspension, the viscosity of the matrix should be reduced to such an extent that it was possible to easily carry out the dosing and mixing of the suspension.
One type of agent, rheology modifier, especially suitable for use in the suspension of the present invention, contains polimernye (except the usual alkoxysilane) crystal hydroxyquinoline materials that can form thread-like structuring system within a liquid matrix during crystallization in the matrix in situ. Such materials can be in General described as crystalline hydroxycobalamin fatty acids, esters of fatty acids or fatty waxes.
Specific examples of preferred crystalline hydroxyl-containing rheology modifiers include castor oil and its derivatives. Especially preferred are derivatives such as hydrogenated castor oil (HCO) and hydrogenated castor wax. Commercially available crystalline hydroxysteroid the e rheology modifiers based on castor oil include THIXCIN ®manufactured by Rheox, Inc. (currently Elementis).
Alternative commercially available materials are materials suitable for use as a crystalline hydroxyl-containing rheology modifiers. An example of a rheology modifier of this type is 1,4-di-O-benzyl-D-trait in R,R - and S,S-forms and any mixtures of optically active or not.
It is believed that all these crystalline hydroxycobalamin rheology modifiers described above, operate through the formation of thread-like structuring systems of crystallization in situ in the liquid matrix of the suspension according to the present invention or in the premix, which is used for formation of such a liquid matrix. Such crystallization is caused by heating the aqueous mixture of these materials to a temperature above the melting point of the rheology modifier, followed by cooling the mixture to room temperature with continuous stirring of the liquid.
Other types of rheology modifiers, in addition to polimernyh crystalline hydroxyl-containing rheology modifiers, described above, can be used in the suspensions of the present invention. Can also be used polymeric materials that provide the ability to liquefaction under the application of shear loads to the aqueous liquid matrix.
P is egodnya polymeric rheology modifiers include materials such as polyacrylates, polysaccharides or derivatives of polysaccharides. Derivatives of polysaccharides, typically used as rheology modifiers include materials polymer resins. Such resins include pectin, alginate, arabinogalactan (gum Arabic), carrageenan, Gellan gum, xanthan gum and guar gum.

Gellan gum is heteropolysaccharide obtained by fermentation Pseudomonaselodea ATCC 31461. Gellan gum is commercially supplied by the firm CF Keico U.S., Inc. under the brand name KELCOGEL. The methods for the production of Gellan gum are described in U.S. patent No. 4326052; 4326053; 4377636 and 4385123.
In another preferred embodiment, the rheology modifier is a polyacrylate, unsaturated mono - or dicarboxylic acid and 1-30C alkyl ether complex (meth)acrylic acid. Such copolymers are delivered by the company a Noveon Inc. under the trademark Carbopol Aqua 30.
Preferably, the rheology modifier of the present invention is an external modifier rheology. The rheology modifier selected from the group consisting of polimernyh crystalline hydroxyquinoline materials, polymeric rheology modifiers, and mixtures thereof. M is defecator rheology suspension gives the ability to liquefaction under the action of shear loads. Crystal hydroxyquinoline materials are rheology modifiers, forming a thread-like structuring system inside the matrix composition by in situ crystallization in the matrix. Polymer rheology modifiers, preferably, are selected from polyacrylates, polymeric resins, other nasality polysaccharides, and combinations of these polymeric materials.

Preparation of suspension
The suspension of the present invention is obtained by mixing the ingredients with each other. However, the order and the amount of added inorganic pearlescent agent are important factors, and inorganic pearlescent agent should be added in two parts. This method involves the following stages:
a) combining an organic solvent selected from the group consisting of glycerol, sorbitol and mixtures thereof, and from 10% to 66%, by weight, 100% active substance is an inorganic pearlescent agent;
b) adding a modifier rheology and mixing; and
c) adding the rest of the inorganic pearlescent agent.
Inorganic pearlescent agents are insoluble and without appropriate solution behave like wet sand, causing problems in the processing of suspensions. Behavior similar to wet sand, makes a stirring suspension and requires significant effort on the part of the equipment used in the process of mixing. The addition of inorganic pearlescent agent two portions allows to obtain recyclable and homogeneous suspension. When the first addition of inorganic pearlescent agent add pic is Adina from 10% to 66% by weight of the inorganic pearlescent agent and stirred.
Hydrogenated castor oil is the preferred rheology modifier. In cases when, as a rheology modifier is used hydrogenated castor oil, preferably prepared using a batch process premix hydrogenated castor oil and surfactants. The water is heated to a temperature of from 80°to 98°C. Surfactant is then added to the solution and the pH adjusted to 7-8 by using a suitable agent, pH adjustment, for example, NaOH and buffer. The rheology modifier based on hydrogenated castor oil is dispersed in the solution at a temperature above the melting point of the rheology modifier and the mixture emuleret. The premix is then crystallized by cooling the emulsion at the rate of 1±0.2°C/min to the end point of 25°C.
Add gradually the rest of the inorganic pearlescent agent and stirred.
The mixing rate of the suspension pearlescent agent depends on the composition of the suspension: a greater percentage of the pearlescent agent requires a higher mixing speeds compared to a smaller percentage pearlescent agent. To ensure mixing and incorporating pearlescent agent in the composition must be sufficient and constant speed of paramashiva the Oia. However, the magnitude of the shear loads in the process must be maintained at a minimum level to prevent the destruction of the grid created by the rheology modifier.
The following non-limiting examples illustrate the present invention. The percentages are given by weight, unless otherwise indicated.
Viscosity in accordance with the present invention is measured by using a rheometer AR 550 company TA Instruments using a spindle of plate steel with a diameter of 40 mm and a gap of 500 μm. The viscosity at high shear rate (HSV), measured at 20-1and the viscosity at low shear rate (LSV) at 0.5-1can be defined on a logarithmic curve scan shear rate from 0.1-1up to 25-13 minutes at 21°C.
In the Example 1, examples A-D are examples of the suspension of the present invention.
