Description

Gel soap composition and manufacturing method thereof

The present invention relates to a gel soap composition and a method for preparing the same.

In general, solid soap can be divided into fatty acid soap obtained by saponifying oil or fatty acid with alkali, and synthetic surfactant soap containing fatty acid as a main cleaning component and a surfactant as an auxiliary cleaning component. Fatty acid-based soaps are inexpensive, easy to manufacture, and have the advantages of being hard and less prone to softening or abrasion. It has a weakness that can cause the skin to become rough or irritate the skin easily by losing elasticity.

Korean Patent Laid-Open No. 10-2004-0053807 discloses a human body cleansing soap using gelatin. Here, a human body cleansing soap in the form of a jelly was prepared using a surfactant as a main component and gelatin. Because it is in the form of a gel, even if it can be used directly on the skin, there is little irritation. The gel-type soap has these advantages, but there is a disadvantage that the water-soluble substances collected therein flow out due to the osmotic pressure phenomenon due to the concentration difference, and the content is reduced for a short time as the water component evaporates. In addition, there is a problem in that it is difficult to use continuously because the strength and elasticity are not excellent and it is broken during use.
