Technical Field

The invention belongs to the field of daily chemicals, particularly relates to a facial cleanser and a preparation method thereof, and more particularly relates to a crystalline amino acid facial cleanser and a preparation method thereof.

Background

The cleansing cream (emulsion) is a cleansing product which is a first step of using skin care products and is also a crucial step in skin care work, wherein the cleansing cream (emulsion) utilizes a surfactant to reduce the surface tension of dirt and removes the dirt through the actions of wetting, dispersing, foaming, emulsifying and the like. Over-cleaning can disrupt the barrier function of the skin, while if not thoroughly cleaned, the dirt and excess oil adhered to the skin surface can interfere with the absorption of subsequent skin care nutrients.

The traditional face cleaning product mainly adopts a soap base type, contains fatty acid soap, has strong dirt-removing power, is easy to wash, but has large irritation, the skin has tight feeling after washing, and the acid-base balance of the skin can be damaged after long-term use, even a series of skin problems are caused, such as: allergies, acne, and the like. The non-soap base type face cleaning product which takes the amino acid type surfactant as the main component is faintly acid, is close to the pH value of a human body, has moderate decontamination capability, good skin-friendly property and low irritation or almost no irritation, and is suitable for various crowds. Therefore, the amino acid facial cleanser becomes a main stream of facial cleansers in the market, and the crystalline amino acid facial cleanser has good cleaning and skin care effects and has the advantages of naturalness and safety.

However, the problem of poor product stability of the crystalline amino acid cleansing cream currently on the market generally exists, and the problems are mainly reflected in two aspects: firstly, the viscosity of the product is greatly changed along with the temperature, the product is difficult to keep in the original state after being stored for a period of time, the hardness of the paste body is possibly changed, even the problems of water outlet and the like are possibly caused, the extruded paste body can not be ensured to be in a strip shape, and great inconvenience is brought to the use of consumers; secondly, the appearance of the product has larger change along with the temperature, and the granular feeling is easily generated through the cold and hot alternation of the external environment, so that the appearance of the paste is coarse, and the sensory evaluation of the product by consumers is reduced. In addition, in the process of preparing the crystalline amino acid facial cleansing cream, in order to achieve the purpose of crystallization, a high-content solid amino acid surfactant is used in a common product, the solid amino acid surfactant is not easy to be fully wetted and dissolved, and the non-wetted amino acid surfactant is easy to absorb moisture and agglomerate after the temperature of a system is raised, so that the amino acid surfactant is not easy to be fully dissolved, and even a 'fish eye' phenomenon is generated.
