Further, the preparation method of the gulfweed extract in the deep moisturizing cosmetic composition comprises the following steps: cleaning fresh Sargassum, oven drying, and pulverizing to 40 mesh to obtain Sargassum powder; adding sargassum powder into deionized water, heating to 90-100deg.C, leaching with hot water for 10-15 hr, and centrifuging to obtain supernatant I and precipitate I; adding the sediment I into deionized water again, wherein the mass ratio of the gulfweed powder to the deionized water is 1:20-25, performing ultrasonic wall breaking, and performing centrifugal separation to obtain supernatant II and sediment II; mixing the supernatant I and the supernatant II, cooling, and concentrating to 1/3 volume to obtain crude extract; adding ethanol to the crude extract until the mass concentration of the ethanol is 10%, then adding palmitoyl tripeptide-1 and azelaic anhydride, heating to 60-70 ℃, keeping the temperature, stirring for reaction for 1-2h, cooling, and concentrating to 1/3 volume to obtain the product.
Sargassum is a type of seaweed in brown algae, and Sargassum polysaccharide extracted from Sargassum is a polysaccharide compound which is easily dissolved in water and has high viscosity, can stabilize cell membrane in human cells, can be combined with protein in human body to generate anti-dry component, and can make skin smooth. Hydroxyl, carboxyl and other polar groups in gulfweed polysaccharide molecules can form hydrogen bonds with water molecules to combine a large amount of water, polysaccharide molecular chains are mutually interwoven into a net shape, and the water is combined with the hydroxyl, carboxyl and other polar groups through the hydrogen bonds, so that a strong water-retaining effect is achieved. However, the gulfweed polysaccharide has poor fat solubility, so that the skin surface has poor transdermal absorbability, the palmitoyl tripeptide-1 is adopted to form a conjugate with the gulfweed polysaccharide through azelaic anhydride, and the conjugate formed by the palmitoyl tripeptide-1 and the gulfweed polysaccharide can act on the dermis layer, so that the fat solubility of the gulfweed polysaccharide is improved, the skin transmittance of the gulfweed polysaccharide is further enhanced, and simultaneously, the palmitoyl tripeptide-1 can promote the generation of collagen, elastin and hyaluronic acid, improve the water content of skin and reduce fine wrinkles.
Furthermore, the ultrasonic frequency of the ultrasonic wall breaking is 30-40KHz, the ultrasonic time is 1-1.5h, and the ultrasonic temperature is 40-50 ℃.
Furthermore, the dosage of the palmitoyl tripeptide-1 is 0.2-0.5 times of the mass of the gulfweed powder, and the dosage of the azelaic anhydride is 0.01-0.03 times of the mass of the gulfweed powder.
Further, the preparation method of the rose flower extract in the deep moisturizing cosmetic composition comprises the following steps: taking fresh cleaned rose petals, air-drying, crushing, and sieving with a 100-mesh sieve to obtain rose pollen; adding distilled water, stirring for 0.5-1h, pumping into a PEF treatment system at a speed of 5-10mL/min, and performing high-pressure pulse extraction to obtain extractive solution; adding malic acid into the extractive solution, heating to 90-110deg.C, reacting for 3-5 hr under stirring, cooling, and concentrating to 1/3 volume.
The rose flower is rich in vitamin E, vitamin C and flavonoid substances, can effectively eliminate free radicals on skin, and has the effects of delaying aging, reducing melanin generation, supplementing water and preserving moisture. The invention adopts a high-pressure pulse method to extract the rose flowers, so that the active ingredients in the rose flowers can be extracted efficiently. The inventor finds that the rose flower extract has good effects of moisturizing and delaying aging, but contains a large amount of hydroxyl groups in the rose glycoside, and has certain irritation to sensitive skin, so that the inventor adds malic acid to carry out esterification reaction in the preparation process of the rose flower extract, and effectively reduces the irritation of the rose glycoside to the skin. Meanwhile, the redundant malic acid can also remove redundant keratinocytes on the surface of the skin, thereby being beneficial to the absorption of the cosmetic composition.
Further, the distilled water is 5-8 times of the mass of the rose pollen; the electric field strength extracted by the high-voltage pulse method is 20-30kv/cm, and the number of pulses is 8-15.
Furthermore, the amount of the malic acid is 0.02-0.04 times of the mass of the rose pollen, and the stirring speed is 500-700rpm.
Further, the transdermal absorbent in the deep water-replenishing cosmetic composition consists of lactobionic acid and nerol according to the mass ratio of 23-27:16-20.
