The present invention relates to aqueous liquid cleansing compositions which are biphasic in nature. More specifically, such compositions are characterized by (assuming they vestibules quite a long period of time after shaking) as the upper water layer, and separate the lower aqueous layer. In the present invention the formation of two-phase fluid is induced by the use of a sufficient number of Polydextrose where Polydextrose is within the approximate interval distribution of molecular weight. The number of Polydextrose required to induce phase formation, can be reduced if you use a small amount of salt.

Two-phase fluid, defined by the General fact that the fluid is divided into two phases, are not new. The majority of these liquids include one layer, which is a water layer and a second layer that includes not miscible with water oily material.

U.S. patent No. 3718609 (Weimer), for example, discloses a liquid detergent composition having an aqueous layer and a layer of a liquid not miscible with water oily material. When shaken, the liquid forms a temporary emulsion of oil-in-water.

Similarly, U.S. patent No. 3810478 (Olson Jr. et al.) discloses a two-phase composition of the shampoo, izgotovlenie is by obtaining essentially the polar and lipophilic parts of the composition of the shampoo.

Two-phase composition comprising upper and lower aqueous phase is also described in the prior art. Application for U.S. patent No. 09/643142 (Williams et al.), titled ″A Separating Multi-Phase Personal Wash Composition in a Transparent or Translucent Package″, discloses a two-phase composition containing:

(a) 5-35% of a surfactant;

(b) 1-12% of thickener;

(C) 4-20% of polyalkyleneglycol and

(d) a sufficient number nichelatura mineral salts to induce phase separation.

Despite the fact that the total amount of salt/electrolyte is not specifically discussed in the above description of the examples it is obvious that the amount sufficient to induce the formation of two-phase layer is at least about 4%, 5%, 6% and above. On the contrary, in the present invention the salt is not required for two-phase education and, if used, is present typically in amount of less than 3 wt. -%, preferably about 2% of the mass. or less, and more preferably about 1% of the mass. or less. As discussed in the description below, the use of small amounts of salt (i.e. about 0.5%-3%, preferably of 0.5%-1%) really allows you to use a smaller amount of Polydextrose to induce biphasic education.

Additionally, in contrast to the compositions according to Williams et al., compositions of the present invention inducer what are Polydextrose and are stable, and they do not require any thickener or polyalkyleneglycol, as required in the compositions Williams.

EP-A-0116422 (Reckett and Coleman) also discloses a multilayer compositions, in which the two liquids are dispersible and which are separated upon standing. Also at least 6% salt/electrolyte (e.g., sodium hexametaphosphate) is required in these compositions (see p.4, lines 17-19). Two-phase fluid of the invention are induced by Polydextrose, not salt, and salt is not required, although you can use a small amount (for example, up to about 3%, preferably about 2% or less, more preferably about 1.5% or less, most preferably about 1% or less).

In addition, the compositions of the present invention are preferably used in a translucent or transparent compositions (i.e. for a favorable touch effect), and they are not disclosed and are not available in ER 0116422.

Unexpectedly, the authors of the present invention have found that a two-phase fluid (e.g. liquid, which are divided into upper and lower liquid water) can be induced only by adding a sufficient number of specifically defined Polydextrose.

More specifically, the present invention includes a liquid cleaning compositions for personal care products containing

(1) 5-75%, preferably 6-40% of the mass. surface-the asset is wow substances, selected from the group consisting of anionic surfactants, nonionic surfactants, amphoteric/zwitterionic surfactants, cationic surfactants and mixtures thereof;

(2) at least about 15%, more preferably at least 20% of the mass. Polydextrose or mixture of molecules Polydextrose, the degree of polymerization (for example, the number of linked glucose units) is from 4 to 22 (this corresponds to a molecular weight MW of from about 600 to about 3600); and

(3) water and auxiliary ingredients to balance.

In the second embodiment of the invention, the invention includes compositions that use at least 1% salt and content Polydextrose can be 10%. In another embodiment of the invention includes a composition which is at least 2% of salt and content Polydextrose be only 5%.

The present invention relates to a two-phase liquid cleaning compositions, in which the formation of two-phase fluid is induced by the addition of sufficient Polydextrose, where the degree of polymerization (a certain number of related groups of glucose) is in the range from 4 to 22. This corresponds to approximately MW from about 600 to about 3600.

More specifically, the invention includes

(1) 5-75% m is SS. surface-active substances selected from the group consisting of anionic surfactants, nonionic surfactants, amphoteric/zwitterionic, cationic surfactants and mixtures thereof;

(2) at least 15% of Polydextrose, where the degree of polymerization (i.e., the number of linked glucose units) is from 4 to 22 or has a MW of from 600 to 3600), MW is preferably from 700 to 1800, more preferably from 900 to 1500, and most preferably from 900 to 1200; and

(3) water and auxiliary ingredients to balance.

The main idea below of the invention is that, when you add a sufficient quantity of a certain Polydextrose, phase separation occurs. For example, it is shown that adding 20% Polydextrose MD180 (1000 MW) are separated. You can use different surfactant system, and a particular type of surfactant is not a limiting factor.

Compositions of the invention can be used in combination with transparent packaging so you can see the liquid. Thus, in the first embodiment of the invention also includes a system that includes the specified transparent or translucent packaging in combination with a liquid.

Typically, once formed two-phase compositions the Oia (for example, the song "settles" after shaking), the viscosity of the lower layer is lower than the viscosity of the top layer.

Also the density of the lower layer is usually higher than the density of the top layer.

Typically, in such two-phase fluids is not visible recrystallization after the composition was kept for 6 months at room temperature.

The final product will have the same viscosity as shower gel, from 100 to 5000 μPA·C, preferably from 200 to 4000 at the shear rate equal to 10-1at 25°S, measured using a Haake RV20 Rotovisko Reometer.

In the second embodiment of the invention uses a small amount of salt, and the amount of Polydextrose required to induce a two-phase fluid decreases. More specifically, in this embodiment the composition comprises at least 1% salt and at least 10% of Polydextrose.

In the third embodiment the composition comprises at least 2% salt and at least 5% of Polydextrose.

The compound, which is added to the composition, which induces the formation of two-phase (multi-phase) fluid is Polydextrose. Usually Polydextrose corresponds to the formula as shown below:

where n (a certain number of linked glucose units) is in the range from about 4 to about 22.

Polydextrose compounds that induce the formation of two phases according to the invention can also be defined molecular weight, which ranges from 600 to 3600, more preferably from 700 to 3000, more preferably from 700 to 1800, most preferably from 900 to 1500.

If p is glucose links or MW should animate, the crucial point is that the structure is such as to induce the formation of multi-phase/two-phase composition, which is determined by such characteristics that in turn define a two-phase fluid (e.g., viscosity and stability in two-phase state).

The number of Polydextrose used to induce two-phase state, can vary depending on whether you are using a salt/electrolyte interface.

Thus, for example, if salt is not used (no or applying a small amount of salt also distinguishes this invention from other two-phase fluids of the prior art, where a relatively large amount of salt, for example more than 3 wt. -%, actually required to induce a two-phase fluid), then you need at least 15% of the mass. Polydextrose to induce phase separation. If you add some amount of salt (e.g., at least about 0.5%, preferably at least 1.0%), the required number of Polydextrose is reduced to 10% of the mass. If you use at least 2% of salt, the amount of Polydextrose can reach 5%.

There is also usually a balance between the amount of surfactant and the amount of Polydextrose. Usually fewer surface-sports the matter requires more Polydextrose and Vice versa, a greater amount of surface-active substances requires less Polydextrose. Thus, for example, with the introduction of 5-10% of the mass. surfactants may require about 40% or more Polydextrose, and the introduction of 35% of the mass. surfactants may require only about 10-15% of Polydextrose, even in the absence of salt.

Usually the upper limit Polydextrose is about 75%. This is no upper limit as to induce a two-phase fluid.

If you use salt/electrolyte, it will usually be used in amounts of from 0.5% to not higher than 4%, preferably not higher than about 3% of the mass. of the total composition.

Preferably the electrolyte is not chelating electrolyte (usually they have a poor ability to biodegradation).

Typically, the electrolyte must be a salt of sulfate, bisulfate, carbonate, bicarbonate, phosphate, chloride, etc. Examples include sodium sulfate, potassium sulfate, ammonium sulfate, sodium chloride and magnesium chloride. Particularly preferred are magnesium sulfate and sodium chloride.

Haake Reometer was used to measure the viscosities of liquid and semi-solid detergents for personal care in a small volume with a viscosity, measured at different shear rates.

Equipment

The tool was rheometer RV20 Rotovisko RC 20, which includes a tripod and a temperature control unit of the sample Cup and balancers to load the sample, a water bath that is maintained at 25°With a computer and a writing device for control and data logging.

The working procedure

The rheometer Haake, computer, monitor and printer included.

Water bath: a water bath filled with water to the desired level, ustanavli what was appropriate temperature, and water bath included.

System of measurement: the sample was loaded into the rheometer and balanced to 25°With:

(a) the corresponding Cup and rocker for a product was chosen, as follows:

i) NV for measuring viscosity products with low viscosity, such as dilute solutions, fruit juices, etc.;

ii) SV1 for measuring the viscosity of liquids with high viscosity, working range from low to average, which consists of SV Cup with the rotor (the balancer). This is the Cup and the balancer, which is usually used to measure shower gels;

b) the rotor (the balancer) is fixed on the upper segment of the measuring system;

C) rheometer RV 20 was regulated using the zero button;

d) the sample was poured into the Cup until it filled nearly three quarters (approximately 20 g) and then the Cup is gently moved through the temperature controller was screwed to the main segment of the rheometer so that he was immersed in the product and the sample was slightly above the rim of the balancer;

e) waited 5-10 minutes after loading the sample to guarantee equilibrium setting temperature (set the settings on the computer while waiting for the establishment of thermal equilibrium).

Computer

a) insert the floppy disk and loaded prior standard file if it is already saved on the disk. If it is not Kranen, in the computer entered the following data:

i) measurement: chose SV1, NV1, SV2 depending on the spindle;

ii) chose four segments for the four shear rate, 1, 10, 100, 400 at 25°and in 10 steps;

b) on the computer screen follow the steps to download the above details:

measurement - identification (recording details of the sample);

measurement - parameter-choice SV1;

dimension - hold immediately (after equilibrium is reached the sample);

C) thus begins the measurement, which takes about 10 minutes.

d) once the measurement is complete, the results are saved on a floppy disk; the results or print, or represented graphically.

Results

The results were recorded as the viscosity in μPA· (SDR) at shear rate 1/s, 10/s 100/s Temperature and size of spindle (balancer) was also recorded for each measurement sample.

Examples

Examples 1-6 and comparative 1-4

Polydextrose (i.e. Polydextrose M) was investigated for its ability to promote the formation of two-phase compositions of the gel in comparison with sucrose, sorbitol and glucose. The results are shown below in tables 1 and 2.

As can be seen from table 1, when using 15-16% surfactant (SLES/CAPB) only Polydextrose able promote phase separation in the absence of salt (examples 1 and 2).

In table 2, shown below, was tested the influence of salt (i.e. MgSO4), as well as the influence of the level of surfactants in comparison with the number of necessary Polydextrose.

This table also shows various moments. First, the table shows that the level of Polydextrose can be lowered without increasing the level of surface-active substances, if you are using a small amount of salt (for example, MgSO4), (see example 4). Also table 2 shows that higher levels of Polydextrose allow the use of much lower levels of surfactants (example 5) conversely, high levels of surfactants allow the use of lower levels of Polydextrose (example 6). Another interesting point is that, apparently, Polydextrose M100 does not form dwuhfaznosti. However, as can be seen from the following table 3, when add salt, formed dwuhfaznosti even at lower levels of surface-active substances.

Examples 7-12 and comparative 5

Various surface-active system is also capable of producing dohpaz the s compositions by combination with appropriate levels of Polydextrose and salt. As in the case of SLES/CAPB, a mixture of laurinavichene ammonium lauryl ammonium and kokoelmanhallinta will also promote phase separation (see table 3 below). Examples 7-9 and comparative 5 compare Polydextrose M with and without salt in a mixture of surfactants. Phase separation is not achieved with only 25% of Polydextrose M (comparative 5), but the phase separation may be achieved by introducing small levels MgSO4or NaCl (tracks 7-9).

Also the addition of small levels of salt promotiom phase separation with another Polydextrose. Such two-phase composition can be obtained by Polydextrose M250 (example 10), Polydextrose M100 (example 11) and Polydextrose M, although the bottom turbid layer in these three compositions (table 3 below). Using small levels of salt, for promotion of education two-phase surfactant compositions can be used a number of different Polydextrose substances with different molecular weights and different number of glucose zvenyu.

Examples 13 and 14 below, similar to examples 11 and 12, except that they use a 5% salt instead of 3%.
