Abstract

A cosmetic composition for shaving according to the present invention comprises: a polyethylene glycol fatty acid ester-based non-ionic surfactant; a glyceryl fatty acid ester-based non-ionic surfactant; and oil, in a certain ratio. The cosmetic composition for shaving is excellent in transparency of the composition and a long-term low temperature storage property, and is excellent in a cutting force due to appropriate warmth and improvement of adhesion of skin and a razor blade when shaving. Since a moisturizing effect of the skin is increased after shaving, stimulus is less and a sense of use can be improved.

Description

[Composition for shaving]

The present invention relates to a cosmetic composition for shaving comprising a polyethylene glycol fatty acid ester nonionic surfactant, a glycerin fatty acid ester nonionic surfactant, an oil and a polyhydric alcohol.

BACKGROUND ART [0002] In the field of shaving compositions, paste-type shaving creams and aerosol shaving foams are mainly used, in which bubbles are produced by a surfactant solution centered on soaps produced by neutralizing fatty acids.

First, a composition for shaving with a soap component needs to produce foam by itself when it is used. Since the surfactant component including soap has poor continuity and shape retention, there is a problem that bubbles are likely to be lost or decreased during shaving .

Aerosol type shaving foam is foamed by vaporization of propellant using high fatty acid salt such as palmitic acid or stearic acid in order to keep the foam and physically foams, . Therefore, even during shaving, the foam shows excellent retention on the skin. However, such bubbles cause a problem of causing dryness and irritation of the shaving area due to excessive sebum detachment after use. In addition, the aerosol-type shaving foam is disadvantageous in that the contents are excessively sprayed beyond the required amount in the container during actual use and rinsed several times with water after use. The bubbles formed after spraying are mostly gaseous and have a low water content, so it is necessary to wet the skin or shaver with water beforehand and soften them. In addition, the aerosol type shaving foam is mainly used for filling the iron container with gas, but it is difficult to prevent leakage of gas due to corrosion of the container, breakage of the container, etc. There is a problem of stability. In order to solve this problem, there is a product which adopts an aluminum material container. However, since the strength is low, there is a high possibility that the container is broken even in a small impact. In addition, there is a possibility that problems such as inhalation of the filled gas during foaming may occur during use.

There is a non-aerosol product which compensates for the above problems and gives a feeling of heat to the shaving area to open the pores and wet and expand the shaving area to facilitate shaving. However, the manufacturing cost is increased by using the two-chamber container.

There is a problem that since the content of the oil is small, it is difficult to sense the substantial moisturizing effect after use, and the transparency is deteriorated when containing an excessive amount of oil and the stability over time including low temperature is poor.
