Embodiment 1

[0351] (preparation)

[0352] A foaming composition according to Example 1 was prepared by mixing the ingredients shown in Table 1. The numerical values ​​for the amounts of ingredients shown in Table 1 are all based on "% by weight" of the active raw material.

[0353] Table 1

[0354]

[0355] First, 0.53 g of polyquaternium-67 (PQ-67) as a polycation and 69.27 g of water were charged into a beaker. They were heated to 70°C and mixed with a stirrer for 1 hour to prepare a solution. Next, 0.20 g of phytic acid was added to the solution to prepare an aqueous DIC-gel solution.

[0356] Then 30 g of polydimethylsiloxane (oil) was added to the DIC-gel aqueous solution, and mixed with a homogenizer at 6000 rpm for 20 minutes to obtain a foaming composition.

[0357] (evaluate)

[0358] 45 g of the foaming composition according to example 1 and 5 g of LPG (0.31 MPa) as propellant are charged into an aerosol bottle equipped with a dispenser. After shaking the aerosol bottle...

Embodiment 2-4 and comparative example 1-2

[0361] (preparation)

[0362] Foaming compositions according to Examples 2-4 and Comparative Examples 1-2 were prepared by mixing the components shown in Table 2. The numerical values ​​for the amounts of components shown in Table 2 are all based on "% by weight" of the active raw material.

[0363] Table 2

[0364]

[0365] (evaluate)

[0366] 45 g each of the foaming compositions according to Examples 2-4 and Comparative Examples 1-2 and 5 g of LPG (0.31 MPa) as propellant were charged into an aerosol bottle equipped with a dispenser. After shaking the aerosol bottle well, the dispenser is activated to discharge the foaming composition in foam form. The stability of the foam was visually observed and evaluated according to the following criteria.

[0367] Stability: maintain foam for more than 1 minute

[0368] Unstable: bubble bursts within 1 minute

[0369] The evaluation results are shown in Table 2.

[0370] It was found that DIC gel was able to stabilize foams...

Embodiment 5

[0372] (preparation)

[0373] A foaming composition according to Example 5 was prepared by mixing the components shown in Table 3. The numerical values ​​for the amounts of components shown in Table 3 are all based on "% by weight" of the active raw material.

[0374] table 3

[0375]

[0376] (evaluate)

[0377] 45 g of the foaming composition according to example 5 and 5 g of LPG (0.31 MPa) as propellant are charged into an aerosol bottle equipped with a dispenser. After shaking the aerosol bottle well, the dispenser is activated to discharge the foaming composition in foam form.

[0378] The sensory test for the foam was carried out as follows.

[0379] The smoothness of the hair samples was evaluated by 5 panelists according to the criteria shown below and averaged. The results are shown in Table 4 in the cells "untreated hair" and "before shampooing".

[0380] The foam thus obtained with the foaming composition according to Example 5 was applied to the above untr...

Abstract

The present invention relates to a foaming composition comprising: (a) at least one cationic polysaccharide; (b) at least one crosslinker having three or more acid groups or salt thereof; (c) at leastone oil; and (d) at least one physiologically acceptable volatile medium, wherein the amount of the (c) oil(s) in the composition is 10% by weight or more, preferably 15% by weight or more, and morepreferably 20% by weight or more, relative to the total weight of the composition. The composition according to the present invention can form a foam which is stable over time.

Description

technical field [0001] The present invention relates to foams comprising dynamically and ionically cross-linked (DIC) gels and oils. Background technique [0002] Foams are used in a wide variety of cosmetic products such as shampoos, facial cleansers and hair treatments. Foam is preferred in terms of handling, for example, because dripping of makeup through the fingers is prevented or reduced. [0003] Recently, there has been a need to prepare foams that can include large amounts of oil. For example, it may be preferable for a hair conditioner that can provide hair beautifying effects under wet and dry conditions to form a foam including a large amount of oil for combability of hair and the like. [0004] However, it is difficult to include large amounts of oil in the foam because oil can act as a defoamer. Therefore, a foam including a large amount of oil tends to be unstable or easily break the cell structure in the foam. Contents of the invention [0005] It is th...
