Soap suitable for sensitive skin and preparation method of soap

Abstract

The invention discloses soap suitable for sensitive skin and a preparation method of soap. The preparation method comprises the following steps: (1) performing the saponification reaction on fish oiland a sodium hydroxide solution for 1 to 8 h, and then performing salt precipitation and alkaline precipitation to obtain a pure soap base with the content of fatty acid of 60 percent or more; (2) adding deionized water while the soap base is stirred, when the temperature reaches 70 to 80 DEG C, successively adding decyl glucoside, glycerol and stearic acid, and adjusting the pH value of the solution to 6 to 7; and (3) finally adding trehalose and vegetable essential oil, stirring for 1 to 10 hours, and standing to obtain the soap. The soap adopts natural fish oil as an emulsifier, so that theoil stains and contamination stains can be effectively removed, and the soap is easy to rinse, mild and non-irritating; and moreover, the used raw materials are nontoxic, the production process is environmentally friendly, and the market value is high.

Description

technical field [0001] The invention relates to the technical field of daily chemical product processing, in particular to a soap suitable for sensitive skin and a preparation method thereof. Background technique [0002] In recent years, with the prosperity and development of modern industry, the number of pollutants produced by petroleum, printing and dyeing, chemical industry, agriculture, and human daily life has increased rapidly. Disaster weather such as smog and sandstorms is increasingly invading people's delicate skin and suffering from skin diseases. The proportion of the population is increasing. Sensitive skin is a kind of skin that is always on high alert. Skin allergies can cause skin dryness, peeling, redness, oiliness and even sensitivity and tingling. Most of the common soaps on the market are obtained by the saponification reaction of chemically synthesized surfactants. This kind of soap has a high pH value, while human skin is weakly acidic, so it will de...
