Description

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

[Conventional technology]

In recent years, foam-forming aerosol types have been widely used as skin cosmetics, hair cosmetics, glass cleaners, and the like. Foam-forming aerosol compositions used in such products have heretofore been based on cationic polymers and anionic polymers (JP-A-57-197206) and those using polyoxyethylene-oleyl ether (JP-A-59-197206). 4
8-38286), polyoxyethylene-sorbitan fatty acid ester, and those using sorbitan fatty acid ester are known. However, these foam-forming compositions have the drawback that the foams formed are not stable and are easily crushed, so that a good feeling and effect of use cannot be obtained.

[Problems to be solved by the invention]

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

[Means for solving problems]

That is, the present invention contains a cationic polymer, an anionic surfactant and a nonionic surfactant, and the weight ratio of the cationic polymer and the anionic surfactant is 1: 0.01-.
A foam-forming aerosol composition is provided, characterized in that it is 1: 0.3.

〔The invention's effect〕

The foam-forming aerosol products of the present invention are capable of forming foams with a fine texture and excellent stability, as will become apparent in the examples below.

(1) Stability of foam A sample stock solution filled in a hermetically sealed container together with the types and amounts of propellants shown in Tables 1 and 2 was injected into a wide-mouthed cylindrical glass container to generate a fixed amount of foam. The foam was subjected to a sensory test by 20 panelists to evaluate its stability. The stability was evaluated by determining the degree of resistance to breakage when crushed by hand according to the following criteria.

◎: Stable and hard to break ○: Slightly fragile △: Slightly fragile ×: Slightly broken (2) Good texture of foam (1) Generate bubbles as in (1), perform sensory test, and touch The texture of bubbles when viewed was evaluated according to the following criteria.

⊚: Fine and creamy ○: Slightly coarse Δ: Slightly coarse X: Rough and watery Examples 1 to 10 A foam-forming aerosol composition having the composition shown in Tables 1 and 2 was prepared. , Texture and foam stability were evaluated. From these tables, the cationic polymer, the anionic surfactant and the nonionic surfactant were all contained, and the weight ratio of the cationic polymer and the anionic surfactant was 1: 0.01 to 1: 0. The composition of the present invention of No. 3 gives a fine and stable foam, but the compositions of Comparative Examples 1 to 5 lacking any of these and the weight ratio of the cationic polymer to the anionic surfactant are Is 1: 0.01
It can be seen that the composition texture of Comparative Examples 6 and 7 outside the range of ˜1: 0.3 and the foam with good stability cannot be obtained.
