The present invention relates to oil-containing starch granules, comprising the starch, forming a matrix for the specified granules, fragrance oil and a compound of a specific structure to suppress migration of the oil to the surface of starch granules. More specifically, the present invention relates to oil-containing starch granules, including a certain perfume oil, contributing to the delivery of exerting a beneficial effect of the additive to the substrates, such as fabrics, hard surfaces, hair and skin contact starch granules with such a substrate.

Rationale inventions

Adding fragrances to liquid detergent compositions to impart a pleasant aroma or odor of such detergent compositions are well known in the prior art. The presence of odorants provides favorable aesthetic impact on the consumer when using the scrubbing composition and is usually a sign of freshness and purity of the washed fabric with a pleasant smell. However, despite the enhanced flavor the detergent composition, a relatively small fraction of the smell of odorant is transferred to the fabric in the washing process. First of all, because the ingredients odorants in the liquid composition is rapidly dispersed and diluted in the wash water for washing and water for rinsing. Therefore, only the comparative is a limited number of odorants is in contact with the fabric during washing, the main part of odorants released from the washing machine with proryvnym solution. Therefore, there remains a need for technology to improve the efficiency of delivery of odorants from detergent composition to the wash cloth and increase the duration of fragrances on the fabric.

Similarly, there is a need in the technology for the effective delivery of oils other than perfume, such as providing a beneficial effect of the additive, to substrates, such as hard surfaces, hair and skin, so that the duration of such oils on the substrate was significantly increased compared with conventional methods of application such providing a beneficial effect of the additive on the substrate.

The oil used in the present invention may be any oil, which is liquid in the range from 10°C to 90°C and capable of delivery providing a beneficial effect of the additive to the fabric, hard surfaces, hair or skin. For applications in washing the preferred oils are odorants, the term "perfume", as used here, means fragrant substances capable of imparting a pleasant odor to the fabric, and includes a standard substance, commonly used in detergent compositions to neutralize the odor of these compositions and/or giving these songs a pleasant smell. Odorants are predominantly in the liquid state at ambient temperature, although it is also useful solid perfumes.

Perfume oil according to the present invention includes ingredients with Clog P equal to at least 3, where the Clog P is the calculated distribution coefficient between octanol and water. Clog P is a parameter indicating the solubility or hydrophobicity of the odorants. The higher the value of Clog P, the more hydrophobic odorant. The increase of the coefficient R is opredeleniya provides greater stability (stable smell, slowly exudes washed cloth; Sina D. Escher and Esther Oliveros; A Quantitative Study of Factors That Influence the Substantivity of Fragrance Chemicals on Laundered and Dried Fabrics; Journal of the American Oil Chemist''s Society, Volume 71, No.1, pages 31-40, 1994). Odorant with the size of Clog P value of 3 or more, more efficiently deposited on the surface of the fabric (linen for washing)than perfume, characterized by the value below 3. Therefore, the ingredients odorants of the present invention have a Clog P of about 3 or higher, preferably more about 3.2 and even more preferably more about 3.3V.

Clog P of many ingredients odorants described, for example, in the database Ponoma92 received from Daylight Chemical Information Systems, Inc. (Daylight CIS) Irvine, California. Values are most conveniently calculated using the ClogP program, also supplied Daylight CIS. In addition, the program lists the experimentally derived values of logP, represented by the database Pomona. The calculated logP (ClogP) is usually defined in a fragmented approach by Hansch and Leo (A. Leo, in Comprehensive Medicinal Chemistry, Vol.4, C. Hansch, P.G. Sammens, J.B. Taylor and C.A. Ransden, Editors, p. 295, Pergamon Press, 1990). This approach is based on the chemical structure of odoriferous ingredient and takes into account the number and types of atoms, the atom connectivity, and chemical binding. The ClogP values, which are the most reliable and widely used performance indicators physico-chemical properties, can be used instead of the experimental the different values of LogP, used in this invention. Additional information regarding the values of ClogP and logP can be found in U.S. patent 5500138.

Among the perfumes provided for use in this invention belong to substances such as aldehydes, ketones, esters and the like, commonly used for imparting a pleasant odor liquid and granular deterrent compositions. Naturally occurring plant and animal oils are also commonly used as components of perfumes. Therefore, odorants, useful in the present invention can have relatively simple structures, or may include a complex mixture of natural and synthetic chemical components, which, when applied to the fabric, as it assumes that all give a pleasant aroma or smell. Odorants used in detergent compositions, usually chosen in such a way as to satisfy the standard requirements in relation to flavor, stability, cost, and availability on sale. The term "fragrance fragrant substance (smell)" is often used here, rather, to identify odorants as such, than to denote the fragrance attached to this odorant.

Other oils that may be useful for the application of providing a beneficial effect of the additive on one or more of the above-mentioned substrates, comprising them from the tissue, hard surfaces, hair and skin include vitamins, such as vitamin E (tokoferolov esters), modified and unmodified silicone oils, surfactants, softeners tissue, fatty alcohols, fatty acids, fatty esters, etc. These oils can be used as such or may be a combination of any of the aforementioned oils.

Detailed description of the invention

Starches suitable for the starch granules of the present invention, can be obtained from raw starch or modified starch derived from tubers, fruits, legumes, cereals and grains, such starch as corn starch, wheat starch, rice starch, starch from waxy maize, oat starch, manioc starch, starch from waxy barley and waxy rice, sweet rice starch, amioka, potato starch, tapioca, oat starch, starch from cassava and the corresponding mixture.

Modified starches suitable for use include hydrolyzed starch, diluted acid starch esters of starch and long-chain hydrocarbons, acetates, starch, octenylsuccinate starch and an appropriate mixture.

The term "hydrolyzed starch" means substances Alyosha odnogo type, such as corn starch, maltodextrins and dried corn syrup.

Organic compound used to inhibit migration of the oil to the surface of the granules, preferably represents amidoamine having the following formula:

where R1= C12-C30- alkyl or alkenyl,

R2= R1CONH(CH2)m,

R3= (CH2CH2O)pH, CH3H

n = 1-5,

m = 1-5 and

p = 1-10.

In the preferred softening compound of formula (I)

R1= C16-C22-alkyl,

n = 1-3,

m = 1-3 and

p = 1.5-to 3.5.

In the above formulas, each of R1and R2independent means long-chain alkyl or alkeneamine group containing from 12 to 30 carbon atoms, preferably from 16 to 22 carbon atoms, such as, for example, dodecyl, dodecenyl, octadecyl, octadecenyl. Usually R1and R2are derivatives of natural oils containing fatty acid or mixture of fatty acids such as coconut oil, palm oil, tall oil, rapeseed oil and fish oil. Also acceptable chemically synthesized fatty acids. Preferred are saturated fatty acid or mixture of fatty acids, and in particular gidrirovanny tall (H-tall) acid (also called "solid tall is IR"). Typically and preferably R1and R2are derived from the same fatty acid or mixture of fatty acids.

R3means (CH2CH2O)pH, CH3or H, or may be an appropriate mixture. When R3means preferred (CH2CH2O)pH group, p is a positive number representing the average degree of amoxilonline, and is preferably in the range from 1 to 10, in particular from 1.5 to 6, and most preferably from 2 to 4, for example equal to 2.5, each of n and m means an integer from 1 to 5, preferably from 2 to 4, especially 2. The compounds of formula (I)in which R3means preferred (CH2CH2O)pH group as a whole are referred to here as ethoxylated amidoamine, and the term "hydroxyethyl" is also used to denote (CH2CH2O)pH group.

Detergent compositions for washing according to the invention can contain one surfactant or a mixture of such substances selected from the group comprising anionic, nonionic and cationogenic surfactants.

Any suitable nonionic detergent compound may be used as surfactants in the present detergent compositions for washing, many of which are described in various periodicals the Detergents and Emulsifiers, by John W. McCutcheon. In these volumes the above chemical formulas and trade names of industrial nonionic detergent, marketed in the United States, and, in fact, all such detergents can be used in the present compositions. However, it is highly desirable that such non-ionic detergents were the product of condensation of ethylene oxide and higher fatty alcohol (though instead of a higher fatty alcohol may also be used higher fatty acid and alkyl- [octyl, nonyl and isooctyl-] phenols). Higher fatty components, such as alkali, these alcohols and the resulting condensation products are usually linear and contain 10-18 carbon atoms, preferably 10 to 16 carbon atoms, more preferably 12 to 15 carbon atoms and, sometimes, most preferably 12 to 14 carbon atoms. Since such fatty alcohols are produced industrially only in the form of mixtures, the specified number of carbon atoms is inevitably an average, but in some cases limits the number of carbon atoms can serve as an actually existing limits used for alcohols and the corresponding Akilov.

The content of ethylene oxide (EtO) in nonionic detergents usually varies from 3 to 15 moles of EtO per mole of higher fatty alcohol, although there can be up to 20 moles of EtO. preimushestvenno such content EtO is 3-10 the moles and more preferably 6-7 moles, such as 6.5 or 7 moles per mole of higher fatty alcohol (and per mole nonionic detergent). As in the case of higher fatty alcohols, restrictions on polyethoxylate also specified intervals averages EtO groups present in the condensation product. Examples of suitable nonionic detergents include the proper detergents sold by Shell Chemical Company under the trademark Neodol®, including Neodol 25-7, Neodol 23-6 .5 and Neodol 25-3.

Other useful nonionic detergent compounds include alkylpolyglycoside and alkylpolyglucoside surfactants, which are well known in the art and widely described.

Washing composition may contain linear alkylbenzenesulfonate anionic surfactant, where the alkyl radical contains from about 10 to 16 carbon atoms in linear or branched chains and preferably from 12 to 15 carbon atoms. Examples of suitable synthetic anionic surfactants are alkyl(C4-C20)benzosulfimide sodium and potassium, particularly linear secondary alkyl(C10-C15)benzosulfimide sodium.

Other suitable anionic detergents, which are not necessarily included in the present liquid detergent compositions, are Sul is atnie ethoxylated higher fatty alcohols of the formula RO(C 2H4O)mSO3M, where R is a fatty alkyl with 10-18 carbon atoms, m is 2-6, preferably a value equal to approximately 1/5-1/2 of the number of carbon atoms in R) and M means solubilizers salt-forming cation, such as alkali metal, ammonium or higher of Las, where higher alkyl contains 10-15 carbon atoms. The proportion of ethylene oxide in polyethoxyethanol higher alkanolamine is usually 1-11 ethyleneoxide groups and preferably 2-5 moles ethyleneoxide groups per mole of anionic detergent, most preferably three mole, particularly when higher alkanol contains 11-15 carbon atoms.

The most preferred water soluble anionic detergent compounds are the salts of higher alkylbenzenesulfonate and higher alkyl sulphates with ammonium and substituted ammonium (such as mono-, di - and tri-ethanolamine), alkali metals (such as sodium and potassium) and alkaline earth metals (such as calcium and magnesium).

Modifying additives are necessary components of the liquid detergent compositions of the present invention. In particular, from about 2% to 15% of a carbonate of an alkali metal such as sodium carbonate, and preferably from about 3% to 10%, by weight.

Phosphate modifying additive, and in particular polyphosphate, Selo the aqueous metal (sodium) in the amount of approximately from 5 to 30 mass %, is an integral component of the considered liquid detergent compositions. The number of such polyphosphate modifying additive is preferably from about 8% to 20%.

Examples of suitable inorganic phosphate detergents modifying additives include water-soluble salts, particularly pyrophosphates, orthophosphate and polyphosphates, alkali metal. Specific examples of inorganic phosphate modifying additives include tripolyphosphate, phosphates and hexametaphosphate sodium and potassium.

Aluminosilicate modifying additive type zeolite And, usually hydrated, optional, may be included in compositions according to the invention. Can also be useful hydrated zeolites X and Y, as naturally occurring zeolites can act as detergent builders. Various products of zeolite A, zeolite 4A-type zeolite molecules, where the pore size of approximately 4 angstroms, is often preferred. This type of zeolite is well known in the art and methods of industrial production of the specified type zeolite described in the previous technique, as for example in U.S. patent 3114603.

Zeolite builders generally have the formula

(Na2O)x·(Al2O3)y·(SiO2)z·w H2O,

where x is 1, equal to from 0.8 to 1.2, preferably about 1, z is from 1.5 to 3.5, preferably 2 or 3, or 2 and w is from 0 to 9, preferably from 2.5 to 6. Crystalline types of zeolite suitable for the specified application, include these types of zeolite, described in "Zeolite Molecular Series" by Donald Breck, published in 1974 by John Wiley & Sons, typical of industrially produced zeolites listed in table 9.6 pages 747-749 text, this table is included here as a reference.

Zeolite modifying additives must be a univalent cation-exchanging zeolite, then there must be a silicate of a monovalent cation such as sodium, potassium, lithium (whenever possible) or other alkali metal, or ammonium. The zeolite containing the cation of an alkali metal, particularly sodium, is preferable, as indicated in the above formula. Used zeolites are characterized by a high exchange capacity in relation to calcium ions, which typically corresponds to about 200-400 or more milligram-equivalents rigidity calcium carbonate per gram of the aluminosilicate, preferably 250-350 mg-EQ/g, calculated on the anhydrous zeolite. The preferred amount of the zeolite is from about 8% to 20%.

Other components may be present in detergent compositions to improve performance and in some cases act is as diluents or fillers. Illustrative examples of suitable auxiliary substances are enzymes, additionally contributing to the destruction of some stubborn stains when washing or hard surfaces. Among the most useful enzymes and proteolytic amiloliticescoe enzymes. Other useful excipients are foaming tools, such as lauric-ministerului diethanolamide when foam is desired, and, if necessary, antifoaming agents such as dimethylsilicone fluid. Also useful are polymers, means preventing re-deposition, brighteners, fluorescent brighteners, such as stilbene brighteners, coloring agents such as dyes and pigments, and perfumes.

Starch granules

Granules of starch/AA get using the Capsul starch (industrial product from National Starch). Capsul is octenylsuccinate dextrinase starch waxy maize. The process of dextrinization used for shortening the chain molecules of starch, is what distinguishes the Capsul starch from other types of starches. To obtain Gras is str starch/AA use the following methodology: pre-mix 33% Capsul starch in water, at least, per day, using mixer model GREERCO, 1 l enable air to enter. Take the required quantity of this mixture, add a mixture of aromatic oils and molten amidoamine and homogenized using a mixer Silverson Model L4R. Pour this mixture into a spray dryer elongated, Armfield FT80, and carry out the spray drying at 190°C. and a spray pressure of 0.5-1.0 bar.

The oil content on the surface of starch granules/AA and implementation comparison with starch/silicon dioxide

The study of dormancy which shows what a hydrophobic additive AA significantly reduces the number of odorants (self flavouring substance Dinasty) on the surface of dry starch capsules from 2,89% (without AA) to 0.24% (table 3). In contrast to AA, another study showed that hydrophobic modified silica (Aerosil R974; preferred additive, known from the prior art, patent application WO 01/05926) does not reduce the amount of oil on the surface to such an extent as amidoamine (table 3). Aerosil reduces the amount of oil on the surface (odorant Dinasty) starch granules from 3.09% (without Aerosil) to 2.38% (Aerosil). The oil content on the surface was measured by extraction of the encapsulated particles hexane at room temperature and atmospheric pressure, with subsequent implementation of gas chromatography. Hexane extracts only the aromatic oil from the surface of the particles, but not encapsulated inside the particles.
