Abstract

The invention relates to the field of skin care cosmetics, and provides a camellia oil micro-nano emulsion and a preparation method thereof to solve the problems that the existing camellia oil is sticky in appearance, which is inconvenient for daily skin care; the camellia oil skin care product prepared by the traditional emulsification method is bad in sensory effects and large in particle size,as a result, the dispersion performance in a medium is poor, and the use is not convenient, thus, the development and application of camellia oil are limited in the field of cosmetics. The camellia oil micro-nano emulsion is prepared from the following components by weight percentage: 35-50 percent of camellia oil, 2-8 percent of phospholipids, 0.1-0.3 percent of antioxidant, 2-10 percent of waterand the balance of glycerin. By selecting natural and safe raw materials and adopting proper proportion, the camellia oil micro-nano emulsion prepared by the invention is small in micro-nano emulsionparticle size, thus, the camellia oil is easier to penetrate skin so as to reach better absorbency; the load of the camellia oil is large so as to reach a better moisturizing effect; and moreover, the appearance of the product is transparent or semi-transparent, bringing customers more aesthetic experience.

Description

technical field [0001] The invention relates to the field of skin care cosmetics, in particular to a camellia oil micro-nano emulsion and a preparation method thereof. Background technique [0002] Camellia oil, also known as camellia oil, camellia seed oil, etc. Camellia oil is composed of fatty acids, camellia glycosides, phospholipids, saponins, vitamin E, tannins and other components. Camellia oil is rich in unsaturated fatty acids, as high as 85%, and its fatty acid composition is very similar to that of olive oil. As edible oil, camellia oil can effectively prevent cardiovascular disease, enhance immune function, and accelerate absorption. Camellia oil also has good skin care and emollient effects. Studies have shown that 70-80% of the components of camellia oil are the same as human skin, which has good skin affinity and can maintain normal physiological functions and metabolic activities of skin cells. [0003] The appearance of camellia oil is viscous, and it is...
