Embodiment 1

[0030] A kind of soap suitable for sensitive skin is made from the following raw materials in parts by weight:

[0031] 25 parts of fish oil, 5 parts of sodium hydroxide, 1 part of alkyl glucoside, 3 parts of trehalose, 2 parts of plant essential oil, 5 parts of glycerin, 3 parts of stearic acid, 60 parts of deionized water;

[0032] A method for preparing soap suitable for sensitive skin, comprising the following steps: saponifying fish oil with a sodium hydroxide solution with a pH of 8 in a reaction pot provided with a stirrer and open steam, and the fish oil and the sodium hydroxide solution The weight ratio is 1:2. The impurities and pigments in natural fish oil are removed through two times of saponification and salting out, and then through two times of alkali analysis and one finishing process to obtain a pure soap base with a fatty acid content of more than 60%. Add deionized water in the case of agitator, stop adding water when the amount of water added reaches 80% o...

Embodiment 2

[0034] A kind of soap suitable for sensitive skin is made from the following raw materials in parts by weight:

[0035] 30 parts of fish oil, 10 parts of sodium hydroxide, 3 parts of alkyl glucoside, 1 part of trehalose, 0.5 parts of plant essential oil, 1 part of glycerin, 1 part of stearic acid, 55 parts of deionized water;

[0036] A method for preparing soap suitable for sensitive skin, comprising the following steps: saponifying fish oil with a sodium hydroxide solution with a pH of 10 in a reaction pot equipped with a stirrer and open steam, and the fish oil and the sodium hydroxide solution The weight ratio is 1:10. The impurities and pigments in natural fish oil are removed through two times of saponification and salting out, and then through two times of alkali analysis and one time of finishing to obtain a pure soap base with a fatty acid content of more than 60%. Add deionized water in the case of agitator, stop adding water when the amount of water added reaches 90...

Embodiment 3

[0038] A kind of soap suitable for sensitive skin is made from the following raw materials in parts by weight:

[0039] 27 parts of fish oil, 8 parts of sodium hydroxide, 2 parts of alkyl glucoside, 2 parts of trehalose, 1 part of plant essential oil, 3 parts of glycerin, 2 parts of stearic acid, 57 parts of deionized water;

[0040] A method for preparing soap suitable for sensitive skin, comprising the following steps: carrying out saponification reaction of fish oil with a sodium hydroxide solution having a pH of 9 in a reaction pot provided with a stirrer and open steam, and the fish oil and the sodium hydroxide solution The weight ratio is 1:6. The impurities and pigments in natural fish oil are removed through two times of saponification and salting out, and then through two times of alkali analysis and one time of finishing to obtain a pure soap base with a fatty acid content of more than 60%, which is boiled and opened in steam Add deionized water in the case of agitat...

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...
