Method for preparing soap for shampoo

Abstract

The invention belongs to the technical field of cosmetics or similar dressing preparations, and discloses a method for preparing a soap for a shampoo. The method comprises the following steps: measuring the corresponding proportion of coconut oil, lauroyl glutamic acid and purified water, adding water and amino acid and heating the materials to prepare a mixture; steaming the material in a water-jacket heating mode after the oil is measured, wherein the temperature of the oil and the temperature of the amino acid are between 70 DEG C and 80 DEG C, then adding the mixture of water and amino acid, mixing the materials and performing a heating reaction, boiling the materials for 4 h, and pouring the material into a model; putting the material into a cold storage for 1h, cooling the material and performing solidification moulding; and drying the material for 2 to 3 weeks. The prepared soap has good preservation quality, strong cleaning ability, less damage to skin than an ordinary soap, and the preparation process is relatively simple. The soap can foam in the shampoo, and the foam is dense and stable, and the soap can be used as a surfactant, which has the effects of cleaning and foaming.

Description

technical field [0001] The invention belongs to the technical field of cosmetics or similar toilet preparations, and in particular relates to a preparation method of soap used for shampoo. Background technique [0002] At present, the closest prior art: at present, what most factories make soap seeds adopts caustic soda saponification reaction, promptly dissolves caustic soda in water and produces saponification reaction with oil heating to obtain soap seeds. This method is convenient but does not take mildness into account. Alkaline products are irritating to the skin. After use, the skin tends to dry out and have poor moisturizing properties. At the same time, the alkaline environment is not conducive to the effect of the medicinal liquid extracted from Chinese herbal medicine (most Chinese herbal medicinal liquid is acidic), and will cause loss due to acid-base neutralization reaction. [0003] In summary, the problems in the prior art are: [0004] (1) Amino acid is us...

Problems solved by technology

This method is convenient but does not take mildness into account. Alkaline products are irritating to the skin, and the skin tends to dry after use, with poor moisturizing properties, and even worse, it will aggravate the aging of the stratum corneum

At the same time, the alkaline environment is not conducive to the function of the medicinal liquid extracted from Chinese herbal medicine (most Chinese herbal medicinal liquid is acidic), and it will cause loss due to acid-base neutralization reaction
