Description

Skin Cleansing Composition

The present invention relates to a skin cleanser composition containing a natural liquid soap having a saponified vegetable oil, and more particularly to a cleanser composition which maintains product transparency even at a low temperature and has excellent viscosity unlike other detergent compositions containing vegetable oils. To a skin cleanser composition having improved convenience.

In recent years, there has been a growing interest in safe natural ingredients for skin and environment, and it has been known that it does not contain conventional synthetic surfactants such as SLS (sodium lauryl sulfate) or SLES (sodium laureth sulfate) The number of cleaning products based on the ingredient is increasing.

As a result of these changes, products containing natural beauty soap made by saponifying vegetable oil and natural liquid soap made by using such technology are being continuously released, and these natural liquid products have a high preference for transparent properties.

However, such a product containing such a natural liquid cosmetic soap tends to be frozen at a low temperature, and has a disadvantage in that stability is deteriorated due to precipitation at low temperature storage. In addition, when the viscosity is low due to the low viscosity of the natural component, it is difficult to maintain transparency when the viscosity is increased. In addition, when the viscosity is excessively increased by using an aging agent, the flowability at low temperature is inhibited, and when the aging agent is used in a low temperature environment, the agglomeration occurs, which is inconvenient when used as a pump.

Korean Patent No. 1554234 discloses a detergent composition containing a vegetable oil based on a transparent liquid base which does not contain a synthetic surfactant or soap component and has a high content of fatty acid. And the moisture retention time of the vegetable oil is maintained by shortening the saponification time to 30 minutes or less. However, since the saponification time is short, the saponification is not sufficiently performed and the basic materials remaining are not verified. Also, the viscosity is low and the ease of use is low, and the product transparency at 10 ° C or less, And it has a limitation in using the product.

Korean Patent Publication No. 2012-0058721 discloses a low stimulus, high moisture cleansing composition containing a vegetable oil, which comprises a synthetic vegetable oil containing no synthetic surfactant or soap component and having a fatty acid having a carbon number of 18 or more in the total fatty acids of 60 wt% However, since the saponification soap liquid phase and polyol are used without using an auxiliary surfactant, the low temperature stability is lowered and the viscosity is also lowered. have.

Under these circumstances, the present inventors have developed a detergent composition which maintains product transparency even at a low temperature and is excellent in low-temperature flowability as well as in bubble quality and maintains a degree of not so low, as a composition containing a liquid soap having saponified vegetable oil And a cleaning agent composition having the above characteristics was completed by controlling the ratio of the liquid soap and the amphoteric surfactant in which the vegetable oil was saponified.
