The invention relates to the technical field of medicine preparation processes, discloses a preparation process of inositol nicotinate tablets, and aims to improve uniform distribution and particle stability of medicine components. The process comprises the following steps: premixing a filling agent and a disintegrating agent to form a first auxiliary material mixture; mixing inositol nicotinate with a first auxiliary material, and screening to obtain a second raw material mixture; dry inositol nicotinate particles are obtained through wet granulation and staged drying; optimizing a particle screening process by adopting an airflow screening model to obtain target particles; and finally, mixing with a lubricant and pressing into tablets. Through application of the airflow screening model and segmented temperature control drying based on the dissolution rate, the uniformity, the dissolution performance and the production efficiency of the product are remarkably improved.

According to the antioxidant free radical cosmetic composition and the application thereof and the cosmetic, the antioxidant free radical cosmetic composition is prepared from vitamin C, glutathione and tocopheryl nicotinate according to the mass ratio of (20-35): (3-5): 1, the composition of vitamin C, glutathione and tocopheryl nicotinate is provided, and the proportion is screened and optimized, so that the antioxidant free radical cosmetic composition is obtained. The synergistic effect of the three components in the aspect of improving the antioxidant capacity of the skin is researched, and the synergistic effect can be realized through various mechanisms, including improving the concentration of antioxidants in the skin, prolonging the activity time of the antioxidants and playing a complementary role in different skin levels, so that the optimal synergistic antioxidant effect of the components is realized; the skin care effect is fully exerted, a scientific basis is provided for the application of the composition in a skin care product formula, and the composition has very strong practicability and wide applicability.

The invention discloses a selenium-rich camellia oil capsule capable of effectively improving a health-care effect and a preparation method thereof. The selenium-rich camellia oil capsule contains unsaturated fatty acid, saturated fatty acid, tea polyphenol, camellia saponin, squalene, 14-methylpentadecanoic acid, linoleic acid, stearic acid, linolenic acid, protein, cellulose, vitamin E, thiamine, riboflavin, nicotinic acid, magnesium, calcium, iron, zinc, copper, manganese, potassium, phosphorus and selenium. According to the technical scheme, the quality and the health-care effect of the camellia oil can be effectively improved, meanwhile, the loss of active ingredients is reduced, the oil yield is increased, and the nutritional ingredients of the camellia oil are kept. Besides, the method also has the advantage of environmental protection, as supercritical CO2 can be recycled, the influence on the environment is reduced, the selenium-enriched camellia oil capsule can stay in the intestinal tract of a human body for a long time, the absorption rate of effective components is improved, and unsaponifiable matters, such as gamma-tocopherol, beta-sitosterol and squalene, of the camellia oil are retained.
