A kind of method of preparing cleansing soap with natural sericin stock solution

Abstract

The invention discloses a method for preparing cleansing soap from natural sericin stock solution. The method uses the cocoon shell of natural sericin cocoon silkworm species as material to prepare sericin stock solution, and uniformly mixes the natural sericin stock solution with soap base Injection molding is carried out to obtain cleansing soap. In the preparation process of soap base, the mixed lye of sodium hydroxide and potassium hydroxide is used as the hydrolyzed lye, and the mixture of coconut oil and olive oil is hydrolyzed to obtain fatty acid sodium and fatty acid potassium. The mixture, in which potassium fatty acid has excellent foaming effect and is resistant to hard water, but potassium fatty acid is soft or even liquid, while sodium palmitate and sodium stearate have poor foaming properties, but have excellent cleaning effect in warm water, so Combining the two, while ensuring the strength of the soap body, the cleaning effect is greatly improved, and the solubility of sodium palmitate and sodium stearate in cold water is low, which can ensure that the formed soap body is not easily deformed in a humid environment.

Description

technical field [0001] The invention belongs to the technical field of daily-use chemicals processing, and in particular relates to a method for preparing cleansing soap from natural sericin stock solution. Background technique [0002] Cleansing soap, also known as beauty soap, cleansing soap, and nourishing soap, is a kind of beauty and skin care soap. Traditional cleansing soap will cause dry and tight skin after use, and the soap smell is heavy. Therefore, for a long time, Facial soap is not accepted by the public, and with the change of ingredients and the resolution of these problems, facial soap has become a commonly used and widely used daily chemical; [0003] The main component of facial cleansing soap is sodium fatty acid.

Problems solved by technology

[0003] The main component of facial cleansing soap is sodium fatty acid. Sodium fatty acid has both hydrophilic and lipophilic ends, so it can wrap fat-soluble dirt into small balls and dissolve in water. Therefore, it is effective against dirt, secretions and The excrement has a good cleaning effect, but the cleansing soap is easy to absorb water during use, resulting in the softening of the surface layer of the cleansing soap after use, and the long-term use of the cleansing soap in a humid environment will soften and deform, and the traditional skin care When soap cleans the face, it will have a strong destructive effect on the sebum film on the skin surface. If the sebum film is damaged for a long time and cannot be repaired in time, it will directly cause the skin to become dry and dehydrated, reducing the use effect of cleansing soap. Therefore, how to reduce its damage to the skin while ensuring the cleaning effect of the cleansing soap, so that the skin will not be dry and astringent after use. In order to solve this problem, the present invention provides the following technical solutions
