Embodiment 1

[0029] Embodiment 1, preparation of Sapindus chinensis extract

[0030] Weigh Sapindus sapindus pericarp, dry, crush, add 75% ethanol solution, microwave extraction at 27°C for 20min, microwave power 30-40W, filter through microporous membrane, collect filtrate, remove ethanol, spray dry, and obtain Sapindus sapindus sub-extract.

Embodiment 2

[0031] Embodiment 2, hydrophobic nano SiO 2 preparation

[0032] S1. Add 4 g of ammonia water with a mass percentage concentration of 20% to 150 g of absolute ethanol, add 2 g of water to mix, stir and heat up to 70° C., and stir for 0.5 h;

[0033] S2. Add 6 g of tetraethyl orthosilicate dropwise at a rate of 0.5 g / min to the solution in step S1 above, and keep stirring for 2 hours;

[0034] S3. Add 2.5 g of methyltriethoxysilane dropwise to the solution of step S2 at a rate of 0.5 g / min, heat and stir for 18 hours, filter, wash, and dry to obtain hydrophobic nano-silica with a particle size of 28 nm.

Abstract

The invention relates to a skin cleansing composition and a preparation method thereof. The skin cleansing composition comprises 5-20 parts of sapindus chinensis extract, 5-15 parts of laccarnation acid and 0.1-3.0 parts of nano silicon dioxide. The present invention synergizes with nano-SiO with specific particle size through special modification by adding laccarnation acid 2 , significantly improved the foamability of the Sapindus chinensis extract in a weakly acidic environment, the foam produced is dense and rich, and the foam stability is very good, and the half-life is significantly improved; in addition, the above composition made of The facial cleanser has a good degree of cleanliness. At the same time, it has a high sense of comfort, no sense of tightness, no excessive loss of moisture and oil, and the skin has a better moisturizing degree after cleansing. It is friendly to both dry skin and oily skin.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a skin cleaning composition and a preparation method thereof. Background technique [0002] The thick fleshy peel of Sapindus contains saponin, which can be used for cleaning and is one of the main cleaning agents in ancient times, as long as it is rubbed hard, it will produce foam. Sapindus is rich in glycosides, mainly triterpene saponins and sesquiterpene glycosides, which have strong antibacterial and antipruritic, bactericidal and antiseptic effects, cleansing the skin, removing freckles and whitening. However, the foaming ability and foam stability of Sapindus extract have a great relationship with the pH of the environment in which it is located. The greater the pH value of the environment, the better the foaming ability of Sapindus extract, and the foam is more stable. , and in a weakly acidic environment, the foam performance is poor due to the non-ionic form of Sapin...
