Description

Smooth moisturizing and granulating face-cleaning powder and preparation method thereof

Technical Field

The invention relates to the technical field of preparation of personal care products, and in particular relates to smooth moisturizing and granulating face-cleaning powder and a preparation method thereof.

Background

Skin cleansing has always been one of the most important links to skin care. Human skin, especially facial skin, is constantly in contact with the external environment. Dust, smoke and microorganisms suspended in the air are easily adsorbed on the skin of people; sebum secreted by sebaceous glands is easily oxidized by air and decomposed by bacteria after being reserved for a long time, so that the sebum is harmful to skin; the sweat evaporation can leave solid secretion and the like on the surface of the skin, and the skin is stimulated; dead cells broken off by metabolism of the stratum corneum, together with secreted sebum, sweat and external dust, adhere to the skin to generate dirt, hinder secretion of the sebum and the sweat and breed bacteria; for people who make up frequently, foundations, blushes, eye shadows, lipsticks, etc. applied on the face are easily adsorbed on the skin. If the skin is not cleaned thoroughly, the problems of pore blockage, skin water and oil imbalance, sensitive skin, skin aging and the like are easily caused.

The currently popular face cleansing products in the market are divided into soap base, surface active and soap surface compound systems, are not distinguished for use according to the characteristics of respective skins, and easily thin the horny layer and even destroy the skin barrier to become sensitive skins after a long time. The cleansing powder is the mildest product in the existing cleansing skin care products, helps to clean skin, reduces the allergy rate of the skin, and is sought by women. Today, the beauty market is changing day by day, and the face cleansing powder is gradually becoming one of the irreplaceable skin cleansing products. However, most of the existing techniques for preparing cleansing powders on the market are prepared by grinding, stirring and mixing powder materials uniformly (the disclosed prior art includes CN104825376A, CN102475662A, CN103230350A and CN 103446038A) or by sieving the powder materials uniformly (the disclosed prior art includes CN105687054A, CN105596248A and CN105769729A), and have the disadvantages of different solid powders, such as sedimentation caused by different densities, easy powder lifting during use and the like. The amino acid cleansing product is a more skin-friendly and mild cleansing product at present, has the advantages of no skin tightness after use and strong moisturizing capability, and is a cleansing product suitable for sensitive muscles (the prior art is CN105769729A, CN106309198A and CN 106466235A). But amino acid surfactants generally have both foaming and cleaning capabilities.

(1) acute skin irritation test:

the smooth moisturizing granulated cleansing powders of example 1, example 2 and example 3 were subjected to acute skin irritation test, 4 white guinea pigs were selected for each example, and the test room temperature: 20-24 ℃, relative humidity: 60 to 70 percent. The hair on both sides of the spine of the experimental animal is cut off about 24 hours before the experiment, the hair removing range is 2cm multiplied by 3cm respectively, and the smearing area is 2.5cm multiplied by 2.5 cm. Applying about 0.5mL of the test substance to one side of skin, and applying the test substance as control for 14 days while applying the solvent to the other side for 1 time per day when the test substance is prepared with non-irritant solvent. From the next day, the hair should be cut before each application, the residual test substance should be removed with water or a non-irritating solvent, and the results are observed after one hour. The stimulation response was scored according to the regulations of the cosmetic safety Specification (2015 edition). The results of the acute skin irritation test are shown in table 2:

TABLE 2

Therefore, the acute skin irritation test result of the smooth moisturizing granulated facial cleansing powder disclosed by the invention shows that the facial cleansing powder has no skin irritation.

(2) Acute eye irritation test

The smooth, moisturizing, granulated cleansing powders of examples 1, 2, and 3 were subjected to acute eye irritation testing, 3 healthy adult white rabbits were selected for each example, and the test room temperature: 20-24 ℃, relative humidity: 60 to 70 percent. Animals were acclimated in the laboratory environment for at least 3 days prior to the test. The lower eyelid of one eye of a rabbit and mouse was gently pulled open, and 0.1mL (100mg) of the test substance was dropped (or applied) into the conjunctival sac to passively close the upper and lower eyelids for 1s, thereby preventing the loss of the test substance. The other eye was not treated for self-control. Eyes were not washed within 24 hours after instillation of the test substance. Rinsing can be carried out at 24h, if deemed necessary. If the test result shows that the tested object has irritation, 3 rabbits are required to be selected for carrying out the washing effect test, namely, 30 seconds after the tested object is dripped into the eyes of the rabbits, the tested object is washed for at least 30 seconds by water flow which has enough quantity and high flow speed and can not cause the injury of the eyes of the animals. The eyes of the animals were examined 1, 24, 48, 72 hours after instillation of the test substance, and at

drops

4 and 7. If no irritation response occurred for 72 hours, the test was terminated. If corneal involvement or other ocular irritation is detected and no recovery occurs within 7 days, the observation period is extended to determine the reversibility or irreversibility of the lesion, typically no longer than 21 days. The stimulation response scores were made as specified in the cosmetic hygiene code (2007 edition). The results of the acute eye irritation test are shown in table 3:

TABLE 3

As is clear from the results of the acute eye irritation test in table 3, the smooth moisturizing granulated cleansing powders of examples 1, 2 and 3 did not show irritation reaction in the eye irritation test of rabbits. Therefore, acute eye irritation tests of the smooth moisturizing granulated facial cleansing powder disclosed by the invention show that the facial cleansing powder does not have acute eye irritation.
