Skin cleaning foam and preparation method thereof

Abstract

The invention discloses skin cleaning foam which comprises the following components in percentage by mass: 0.5-50 percent of lauryl alcohol ether phosphate ammonium salt, 0-30 percent of lauryl alcohol ether phosphate potassium salt, 0-40 percent of amino acid surfactant, 0-50 percent of amphoteric ion surfactant, 0-30 percent of non-ionic surfactant, 50-95 percent of water and additive. The preparation method of the skin cleaning foam comprises the following steps of: completely dissolving potassium hydroxide into water; adding lauryl alcohol ether phosphate and triethanolamine; improving the temperature and preserving the heat until the system is transparent; adding the amino acid surfactant, the amphoteric ion surfactant and the non-ionic surfactant and uniformly stirring; and reducing the temperature, adding the additive and uniformly stirring to obtain the skin cleaning foam. According to the skin cleaning foam and the preparation method thereof disclosed by the invention, due to the adoption of a mode, the skin cleaning foam is abundant during use and has comfortable skin feeling after washing; the residue of the surfactants on the surface of the skin is little, so that the stimulus to the skin is avoided; and the skin cleaning foam is suitable for cleaning a whole body, is convenient for use and time-saving and water-saving.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a cleansing foam and a preparation method thereof. Background technique [0002] Research by Japan’s Kao Company has confirmed that skin irritation and tightness after washing from skin care products are partly due to the removal of oil and amino acid moisturizers on the skin surface, but the greater reason is that they are added to skin care products. Adsorption and residue of surfactants in the skin. By comparing lauryl alcohol phosphate and sodium lauryl sulfate, the results show that although the two have similar surface activity and the ability to wash off oil, lauryl phosphate has extremely low membrane damage and is less harmful to the skin. The irritation of the product is very low, and at the same time, the adsorption and residual amount on the skin is very small, so lauryl phosphate salt is a kind of surfactant that is mild to the skin, has strong detergency, and is easy to ri...

AI Technical Summary

Problems solved by technology

Due to the high critical micelle concentration of lauryl alcohol phosphate salt, it is difficult to thicken in the formula. Therefore, if the product viscosity is maintained at a high level, it is necessary to invest a high cost in the thickener. At the same time, the production process is complicated, which is not conducive to production.
