Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field] The present invention relates to an aerosol composition that produces a fine-textured and stable foam.

[Conventional technology]

In recent years, foam-forming aerosol products have been widely used as skin cosmetics, hair cosmetics, glass cleaning agents, and the like. Foam-forming aerosol compositions used in such products have conventionally been based on cationic and anionic polymers (Japanese Unexamined Patent Publication No. 197206/1983), and those using polyoxyethylene-oleyl ether (Japanese Patent Application Laid-open No. 1972-06). 1972
-38286)1. Those using rubitan fatty acid ester and fulvitan fatty acid ester are known. However, all of these foam-forming compositions have the drawback that the foam produced lacks stability and is easily crushed, so that a good feeling and effect of use cannot be obtained.

[Problem that the invention seeks to solve]

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a foam-forming aerosol composition capable of generating foam having a fine texture and excellent stability.

[Means to solve the problem]

That is, the present invention provides a foam-forming aerosol composition characterized by containing a cationic polymer, an anionic surfactant, and a nonionic surfactant.

The present invention further provides foam-forming aerosol compositions in which the M ratio of cationic polymer to anionic surfactant is 1:0.01-1:0.3.

〔Effect of the invention〕

The foam-forming aerosol products of the present invention are capable of forming foams with fine texture and soaking stability, as will be demonstrated in the Examples below. Therefore, the present invention can be applied to hair cosmetics, skin cosmetics, and other detergents in general that utilize foaming to obtain excellent effects.

[Embodiments of the invention]

Next, Examples and Comparative Examples of the present invention will be shown to explain the effects of the present invention more specifically. In addition, the amount of each component is based on weight.

Prior to explaining each side, the test methods adopted by each side will be explained.

(1) Stability of foam A wide-mouthed cylinder injects the sample stock solution filled in a sealed container with the propellants shown in Tables 1 and 2 into the Ranu container to generate a certain amount of foam. , about I'd K with 2
A sensory test was conducted by 0 No9ners to evaluate its stability. For evaluation of stability, the following criteria were used to judge the resistance to breakage when crushed by hand.

◎: Stable and hard to break ○: Slightly easy to break Δ2 easy to break ×: Easy to break The quality of the bubbles when viewed was evaluated as follows: M, semi-standard.

◎: Foam is rough and creamy ○: Foam is slightly coarse b Δ: Foam is slightly coarse The products were prepared and evaluated for texture and foam stability. From these tables, the composition of the present invention containing all of the cationic polymer, anionic surfactant, and nonionic surfactant can produce fine-grained and stable foam;
It can be seen that foams with good texture and stability cannot be obtained from the compositions of Comparative Examples 1 to 5 lacking any one of these. In addition, particularly good foam was obtained from compositions in which the ratio of the cationic polymer to the anionic surfactant was in the range of 1:0.01 to 1:0.3 (Examples 1 to 4 and 7 to 12). You can see what you can get.
