Description

Amino acid cleansing bubble and preparation method thereof

Technical Field

The invention relates to the field of daily cosmetics, in particular to an IPC classification number A61K8/92, and more particularly relates to an amino acid cleansing bubble and a preparation method thereof.

Background

With the accelerated pace of life of people, the demand on the all-in-one functional product is high, the safety of the product is emphasized, and the product is pursued to be mild and non-irritant without injuring the skin; and with the increase of the usage amount of sunscreen and color cosmetics, the makeup removing requirement is gradually strengthened.

Most products on the market at present need to be washed after being unloaded, and two products are used respectively. Common makeup removing products comprise makeup removing water, makeup removing oil or makeup removing cream, makeup removing cream and the like, wherein the makeup removing water is warm and cool, but makeup removing cotton is needed, so that the possibility of potentially damaging the skin is provided; the makeup removing oil or the makeup removing cream has good makeup removing capability, but the skin feels thick, the makeup removing oil or the makeup removing cream needs to be emulsified and cleaned completely, otherwise pores can be blocked to form a closed pore; the cleansing milk is weak in cleansing power. In addition, the products currently on the market, except for the type of make-up remover, have poor removal of water and sun protection. Similarly, most cleansing foam products have poor cleansing power and are difficult to remove from daily makeup.

Chinese patent CN110742840A discloses a camellia seed cleansing powder and a preparation method thereof, the cleansing powder is softer, is suitable for most of skin types, and has certain cleansing capability, but the cleansing powder does not have the effects of removing sun and keeping moisture. Chinese patent CN104666235A discloses a cleansing lotion for removing makeup and cleansing the face and a preparation method thereof, which has the effects of removing makeup, cleansing and moisturizing, but does not solve the stability problem of the cleansing lotion at high and low temperatures.

Most of some face cleaning products on the market at present do not have the effect of removing makeup, and the moisturizing effect is poor after washing, and even some products with the power of removing makeup have poor storage performance, and the phenomenon of sediment or layering appears easily under the environment of high and low temperature to can influence the result of use. After a great deal of research, the applicant finds that the amino acid cleansing foam has excellent cleansing power and moisturizing effect and also has good high and low temperature stability, and the applicant considers that the possible reason is that specific grease, emulsifier and detergent are added into the system, particularly the grease is medium and low polarity grease, the emulsifier is polyether nonionic emulsifier or polyglycerol nonionic emulsifier, and the detergent is a mixture of 1: (0.8-1.2): the combination of the amino acid surfactant, the alkyl glycoside surfactant and the amphoteric surfactant of (0.8-1.2) can form a micro-emulsion structure, so that the product can be demulsified after contacting with color cosmetics, internal grease is released, and the product has excellent removal cleaning power for different color cosmetics. However, the microemulsion can generate an 'austenite ripening' phenomenon, so that the microemulsion particles gradually grow to finally break the emulsion, the affinity of the system to grease is enhanced by selecting an emulsifier containing multiple oleophilic ends, the aggregation of the microemulsion particles can be prevented by adding a specific amino acid surfactant, meanwhile, the 'austenite ripening' degree of the microemulsion is slowed down by adding medium-low polarity grease, and the storage stability of the system is excellent under the combined action. In addition, the micelle is enlarged by a large amount of emulsifier with long hydrophilic chains and lipophilic ends, the irritation caused by the penetration of surfactant monomers can be well avoided, and the existence of free surfactant monomers is further reduced by the formation of a micro-emulsion structure, so that the mildness is further improved, and therefore, the facial cleanser provided by the invention can also be used for eye lips.

In another aspect of the present invention, a method for preparing amino acid cleansing bubbles is provided, which at least comprises the following steps:

(1) uniformly mixing oil and polyol to obtain an oil phase;

(2) mixing and uniformly dissolving water, a cleaning agent, a chelating agent, a pH regulator and a thickening agent to obtain a water phase;

(3) keeping the oil phase in a stirring state, and slowly adding the water phase;

(4) and finally, adding the preservative, uniformly mixing, and discharging to obtain the product.

Has the advantages that:

(1) according to the invention, the combination of the grease, the emulsifier and the detergent in a specific proportion improves the makeup removing capability and the cleaning capability of the cleansing foam, and can effectively remove various color cosmetics and common dirt and grease;

(2) the system strengthens the affinity to grease by selecting the emulsifier containing multiple oleophilic ends, and can prevent the aggregation of microemulsion particles by adding the specific amino acid surfactant, and simultaneously the added low-polarity grease slows down the 'austenite curing' degree of the microemulsion, so that the storage stability of the system is excellent under the combined action;

(3) the micelle is enlarged by a large amount of emulsifier with long hydrophilic chains and lipophilic ends, the irritation caused by the penetration of surfactant monomers can be well avoided, and the existence of free surfactant monomers is further reduced by the formation of a microemulsion structure, so that the mildness is further improved, and therefore, the facial cleansing foam can also be used for eye and lip.
