Cosmetic containing suspended particles and preparation method thereof

Abstract

The invention discloses a preparation method of a cosmetic containing suspended particles. The method comprises the following steps: uniformly mixing and dissolving suspended particle raw materials at85-100 DEG C, keeping the temperature unchanged, adding the obtained mixture into a cosmetic water phase at a rotating speed of 600-700 r / min, keeping the temperature of the water phase at 60-70 DEGC, keeping the rotating speed, and performing continuous and uniform stirring to obtain the suspended particles. The suspended particles account for 1.5-11 wt% of the water phase. The suspended particle is prepared from the following raw materials in parts by weight: 0.05 to 0.2 part by weight of beeswax, 0.05 to 0.3 part by weight of ozocerite, 0.5 to 3 parts by weight of a polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer, 0.1 to 1 part by weight of ascorbyl tetraisopalmitate, 1 to 5 parts by weight of squalane, 0.1 to 1 part by weight of tocopheryl acetate, 0.01 to 0.2 part by weight of vitamin E and 0 to 0.0001 part by weight of a pigment. According to the invention, the spherical particle-shaped suspended particles which are uniform in dispersion, high in aestheticsand uniform in shape can be obtained in the cosmetic.

Description

technical field [0001] The invention relates to a cosmetic, in particular to a cosmetic containing suspended particles and a preparation method thereof, belonging to the field of cosmetics. Background technique [0002] There are many kinds of cosmetics on the market with various effects, and people's demand for the commodity skin feel and efficacy of cosmetics is also increasing. Existing commercially available cosmetics will add various suspended particles to increase the aesthetics and efficacy of their products. The function of suspended particles not only can increase the beauty of the product, but also has the function of improving the performance, especially for essence and gel cosmetics, the suspended particles can wrap the oily ingredients, and the particles can be broken during the application process to release oil and enhance the moisturizing of the product performance. [0003] The preparation of suspended particles in the prior art is generally to first prepa...

AI Technical Summary

Problems solved by technology

[0004] The problems in the above-mentioned prior art are: (1) there are no skin care oils and functional raw materials in the existing suspended particles

Both are macromolecular colloids or fibrous bodies, that is, what we call the hard shell structure, which only serves to increase the appearance and has no synergistic effect

(2) The existing suspended particles have poor applicability and are not easy to spread. After the shell is broken, there will be obvious pigment and non-absorbing particles, which will seriously affect the performance and use effect of the product, and will also affect the efficacy of cosmetics.

(3) Existing suspended particles are prone to color smudges at high temperatures, so this type of product has high requirements for storage and transportation environments. Once smearing occurs, the product’s commerciality will be greatly reduced, affecting sales and user experience

(4) The suspension performance of the existing suspended particles is not good, mainly due to the poor coordination between the matrix and the suspended particles, under the action of external forces such as centrifugation and vibration, the aggregation or sinking of the suspended particles is easy to occur, resulting in product aesthetics and commerciality both affected

[0005] In the prior art, there is also a suspended particle cosmetic made of solid oil, moisturizer, fluid regulator, pH regulator and deionized water, which can form a snowflake-like float in the gel system. The hard shell structure can solve the problem of poor smearability of finished particles, but the main defect of the suspended particles is (1) poor aesthetics, the most direct effect of suspended particles is to increase the aesthetics of the product, due to the limitations of its product formula and preparation method, This product cannot form evenly dispersed spherical particles. Although the snowflake-like suspended matter can be suspended, most of the snowflake-like structures are irregular in size and shape. The suspension in the product is more like precipitates or sediments. Poor aesthetics make it difficult for consumers to accept, and the market response is not ideal

(2) And the snowflake-like suspension can only be suspended in the gel system, which has high requirements on the system and cannot be widely used in various systems, and the product has limitations

(3) The overall melting point of the product is low, and it is prone to color smudges after being combined with pigments, resulting in turbidity of the system
