Description

  The present invention relates to an aerosol composition, more specifically, the undiluted stock solution is foamed, the foam quality and durability are excellent, and the foam formation is good even at low temperatures. When used as a cosmetic, the present invention relates to an aerosol composition having no stickiness during use and excellent gloss and hair unity.

  Conventionally, aerosol compositions have been used in many fields including cosmetics in terms of convenience and the like. Among these, aerosol compositions that become foamy upon ejection are preferred and many are commercially available. There are various foam aerosol compositions, such as those that form bubbles immediately after ejection, those that form bubbles after ejection, and those that form foam after spraying the stock solution in a spray form. In both cases, emphasis is placed on the fineness of the foam and the sustainability of the foam. In recent years, hair colors and perms have become commonplace, so many people with damaged hair are seen, and in cosmetics for hair, feelings such as a smooth hand and a smooth feeling are regarded as important. . Silicones are widely used to realize such a touch and feel. However, in an aerosol composition that forms bubbles, since silicone exhibits an antifoaming action, fine bubbles and a sustained bubble state cannot be realized.

  In order to improve such foam ejection properties and foam quality, various proposals have conventionally been made. For example, a method using a specific anionic surfactant (see, for example, Patent Document 1), a specific nonionic interface, and the like. A method using an activator (for example, refer to Patent Document 2), a method using a specific glucose derivative (for example, refer to Patent Document 3), and the like have been proposed. In terms of feel, it has not been fully satisfactory.

  On the other hand, in hair cosmetics and the like, amine oxide group-containing resins are used for the purpose of setting power, imparting gloss, and conditioning effects. (For example, see Patent Document 4, Patent Document 5, and Non-Patent Document 1.) Also, by combining this amine oxide group-containing resin and a silicone compound, it has excellent setting power, no stickiness, and has a smooth feel and gloss. Although the hair cosmetics to give (for example, refer patent document 6) are disclosed, also about this, by mix | blending silicone, about the quality of foam, the sustainability of foam, especially the foam formation property under low temperature When there was a problem and it was set as the aerosol composition from the bad foam state, it did not reach the level which is fully satisfied in terms of the target setting power, touch, etc., but there was a problem.
