Abstract

PROBLEM TO BE SOLVED: To prepare a foamy cosmetic for the skin or hair capable of easily taken on a hand, having excellent use feeling and good storing stability. SOLUTION: This foamy cosmetic for the skin or hair contains 45-99wt.% of a liquid oil (e.g. liquid paraffin), 0.1-15wt.% dextrin fatty acid ester (e.g. dextrin palmitate), 0.1-20wt.% of a nonionic surfactant excepting the dextrin fatty acid ester (e.g. sorbitan monolaurate) and 0.01-20wt.% water. A propellant (e.g. isopentane) and the above obtained raw liquid in a weight ratio of the former/the latter of (2/98)-(20/80) are filled in a pressure-resistant vessel, etc. This cosmetic containing the raw liquid and the propellant becomes a good foamy state when propelled in the use and readily be coated without dropping the liquid.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamy cosmetic composition for skin or hair, more specifically, cleansing, massage, essence, hair oil, which is easy to take during use, has an excellent feeling of use, and has good storage stability, The present invention relates to a foamy cosmetic for skin or hair which is useful as a cosmetic such as sun oil.

[0002]

2. Description of the Related Art Cosmetics such as cleansing, massage, essence, hair oil and sun oil are cosmetics for applying an oil component to the skin or hair. The conventional non-water-based cosmetics have a drawback that they are poor in stability at high temperatures and fall off during use. In addition, it is possible to make the oily cosmetic material viscous by using a gelling agent, but in this case, there is a problem in that the feeling of use and stability deteriorate.

[0003]

Under such circumstances, as a result of intensive investigations, the present inventors have found that liquid oil, dextrin fatty acid ester, and a nonionic surfactant other than dextrin fatty acid ester and water are allowed to coexist. Foamed cosmetics for skin or hair containing a stock solution and a propellant, when sprayed at the time of use, will be in a good foam state that is easy to apply, has an excellent feeling in use, and has good storage stability. And found the present invention.

That is, the present invention is characterized by containing a liquid oil, a dextrin fatty acid ester, a nonionic surfactant excluding the dextrin fatty acid ester, a stock solution containing water, and a propellant, as a foam for skin or hair. Cosmetics.
