Abstract

The present invention relates to a cosmetic composition for cleansing comprising a powder surfactant and an emulsifier. The cosmetic composition is an oil-dispersed formulation of a cleansing oil-gel cosmetic composition prepared by dispersing a powder surfactant. Since it exhibits excellent cleansing power, exfoliation effect, and foaming ability, as well as a low oil residue after use, it can be effectively utilized in the manufacture of a cosmetic composition for facial cleansing.

Description

Cosmetic compositions for cleaning comprising powdered surfactants and emulsifiers The present invention relates to a cosmetic composition for cleansing comprising a powdered surfactant and an emulsifier, and more specifically, to a cosmetic composition for cleansing designed to enable simultaneous oil-based cleansing and foam cleansing by adding a powdered surfactant in order to eliminate the inconvenience of requiring a separate foam cleansing when using an oil-dispersed oil gel as a cleansing gel. Various types of products such as cleansing oils, cleansing waters, cleansing balms, and cleansing gels are sold for removing makeup. Among them, oil-dispersed cleansing gels (oil gels) have the advantage of high cleansing power and are convenient to use as they do not drip from the hands. However, oil gels have the disadvantage of requiring a follow-up wash with a separate foaming cleanser because they contain a high concentration of oil, leaving a strong oily residue after washing. If one attempts to add a foaming cleansing function to an oil gel to improve this, the following problems arise: 1) The amount of foaming agent (surfactant) to be applied must be sufficient to overcome the defoaming power of the oil. 2) Due to the formulation's non-water-containing characteristics, most foaming agents diluted in water cannot be applied in the amount specified in 1). 3) When applying a powder-type foaming agent, the amount of surfactant specified in 1) must be stably supported within the formulation. Therefore, it is necessary to provide a cosmetic composition capable of stably supporting a powdered surfactant within an oil-dispersed gel formulation, and to devise a facial cleansing cosmetic composition that enables simultaneous removal of makeup and foaming of the face using the same.
