Embodiment 1

[0029] The oil phase and the water phase in the formula are prepared respectively, wherein the proanthocyanidin is 1g, and the content is 1%. Heat and stir separately to keep warm to 80°C, slowly add the water phase into the oil phase, and stir while heating. After complete addition, adjust the temperature to 85°C, stir at 500r / min, and keep it for 30 minutes. After the end, slowly lower the temperature to 80°C, add azone, and vacuum the pressure to -0.04mPa for 20 minutes. When the temperature drops to about 45°C, add a small amount of flavor and fragrance, continue to stir for 10 minutes and discharge. The obtained product has good stability and uniform texture.

Embodiment 2

[0031] The oil phase and the water phase in the formula are prepared respectively, wherein the amount of proanthocyanidin is 2g, and the content is 2%. Heat and stir separately to keep warm to 80°C, slowly add the water phase into the oil phase, and stir while heating. After complete addition, adjust the temperature to 85°C, stir at 500r / min, keep for 20min, then slowly cool down to 80°C, add azone, and vacuum the pressure to -0.05mPa for 20min. When the temperature drops to about 45°C, add a small amount of flavor and fragrance, continue to stir for 10 minutes and discharge. The obtained product has good stability and uniform texture.

Embodiment 3

[0033] The oil phase and the water phase in the formula are prepared respectively, wherein the amount of proanthocyanidin is 3g, and the content is 3%. Heat and stir separately to keep warm to 75°C, slowly add the water phase into the oil phase, and stir while heating. After complete addition, adjust the temperature to 80°C, stir at 500r / min, keep for 20min, then slowly cool down to 80°C, add azone, and vacuum the pressure to -0.05mPa for 30min. When the temperature drops to about 45°C, add a small amount of flavor and fragrance, continue to stir for 10 minutes and discharge. The obtained product has good stability, uniform texture, but darker color.

Abstract

The invention discloses a method for preparing proanthocyanidin whitening sunscreen cream, and belongs to the technical field of skin care products. A scientific formula for proanthocyanidin whitening sunscreen cream and a reasonable and high-utilization-rate sunscreen cream preparation method are provided. The proanthocyanidin whitening sunscreen cream is formed in the way that an aqueous phase and an oil phase are slowly mixed according to certain parts by weight for heat preservation and then stirring is conducted. The oil phase is prepared from oligomerization proanthocyanidin, stearic acid, hexadecanol, isopropyl palmitate, wool fat, olive oil, glycerin monostearate, methylparaben, propylparaben and water. The aqueous phase is prepared from glycerol, triethanolamine, lauryl sodium sulfate, water and azone. The effective component of the whitening sunscreen cream prepared through the method is the oligomerization proanthocyanidin which is a natural polyphenol substance, the oligomerization proanthocyanidin is obtained by purifying and extracting the proanthocyanidin through a macroporous resin isolation technology, and a good whitening sunscreen effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and mainly relates to a preparation method of proanthocyanidin whitening sunscreen. Background technique [0002] When people are exposed to light, ultraviolet rays can also cause damage to human skin, which not only damages the appearance, but may also affect skin health. Moreover, as environmental pollution becomes more and more serious, the destruction of the atmospheric ozone layer is also more and more serious, resulting in the intensity of ultraviolet rays in sunlight becoming stronger, and the damage of ultraviolet rays to people's skin under light is also becoming more and more obvious. [0003] Proanthocyanidins refer to a class of polyphenolic compounds extracted and isolated from plants that can produce red anthocyanidins under hot acid treatment, have strong antioxidant activity, and are used as a good oxygen free radical scavenger Oxidation inhibitor, its molecular struct...
