Embodiment 1

[0021] Take 1KG of sunflower oil soap stock and 1200mL of acetone, mix and stir vigorously, let stand to precipitate to obtain acetone insoluble matter, add the above acetone insoluble matter to 500mL of ethanol to dissolve, centrifuge at 3000rpm for 5min to obtain a supernatant, add buffer to the supernatant Solution and phospholipase A2 0.3mL, react at 42°C for 8 hours, add 20% sodium hydroxide solution to make the pH of the solution 7.0 when the measured acid value is >60. Vacuum rotary evaporation at 45°C for 20min, remove the solvent to obtain enzymatic lecithin 62.7 g, add an appropriate amount of glycerin to 100g to obtain an emulsifier.

Embodiment 2

[0023] Take 1KG of sunflower oil soap stock and 1200mL of acetone, mix and stir vigorously, and let stand to precipitate to obtain acetone insoluble matter. Add 500 mL of methanol to dissolve the above-mentioned acetone insoluble matter, and centrifuge at 3000 rpm for 5 min to obtain a supernatant. Add buffer and phospholipase A2 0.3mL to the supernatant, react at 42°C for 8 hours, add 20% sodium hydroxide solution to make the pH of the solution 8.0 when the acid value is >60, and remove the solvent by vacuum rotary evaporation at 45°C for 15min That is, 64.5 g of enzymatically hydrolyzed lecithin was obtained, and an appropriate amount of glycerin was added to 100 g to obtain an emulsifier.

Embodiment 3

[0025] Take 1KG of sunflower oil soap stock and 1200mL of acetone, mix and stir vigorously, and let stand to precipitate to obtain acetone insoluble matter. Add 500 mL of ethanol to dissolve the acetone insoluble matter above, and centrifuge at 3000 rpm for 5 min to obtain a supernatant. Add buffer and phospholipase A2 0.3mL to the supernatant, react at 42°C for 14 hours, add 20% sodium hydroxide solution to make the pH of the solution 7.0 when the acid value is >60, and remove the solvent by rotary evaporation at 45°C for 20min 66.5g of enzymolyzed lecithin was obtained, and an appropriate amount of glycerin was added to 100g to obtain an emulsifier.

Abstract

The invention discloses a natural emulsifier as well as a preparation method and application thereof, and belongs to the technical field of personal care, the prepared natural emulsifier is from vegetable oil, and the natural emulsifier prepared by an enzymolysis method contains 60-85wt% of enzymolysis lecithin, 10-30wt% of glycerol, 10-30wt% of glycerol, 10-30wt% of glycerol and 10-30wt% of glycerol. The natural emulsifier disclosed by the invention has the characteristics of natural source, mildness, no irritation, low chromaticity, light grease smell, low viscosity, stability and capability of increasing transdermal absorption of active matters. The cream can be prepared into a milky white formula, provides soft, moist and light skin feeling, adopts renewable raw materials, is simple in preparation method, stable in performance, low in production cost and beneficial to industrial production, and conforms to the green and environment-friendly trend of the current society.

Description

technical field [0001] The invention belongs to the technical field of personal care, and in particular relates to a natural emulsifier and its preparation method and application. Background technique [0002] The manufacture of personal care products is inseparable from emulsifiers. Emulsifiers can be divided into two types: synthetic and natural. Chemically synthesized emulsifiers have stronger emulsifying performance and stability, and are cost-effective. Synthetic emulsifiers account for a large proportion of products currently on the market. However, chemically synthesized emulsifiers are irritating to sensitive skin and have a high risk of sensitization. Therefore, emulsifiers with natural origin and good biodegradability will surely become the development trend in the future. [0003] The natural emulsifiers that are currently studied more include lecithin, sugar esters, glycosides and glycerides. At present, natural emulsifiers mainly have problems such as weak ...
