Problems solved by technology

[0006] In the existing sunscreen technology, a single sunscreen method is used to protect against ultraviolet rays, so the mechanism of sunscreen is single. Generally, a chemical sunscreen can only absorb one kind of ultraviolet rays, so multiple chemical sunscreens are needed to increase the anti-ultraviolet ability.

Embodiment 1

[0021] A sunscreen cosmetic prepared by weight of the following raw materials: 16 parts of rosemary extract, 18 parts of ginkgo biloba extract, 10 parts of propylene glycol, 1 part of methylisothiazolinone, 5 parts of carbomer, urine 1 part of capsule, 3 parts of sodium citrate, 4 parts of modified titanium dioxide particles, 5 parts of new UV absorber, 1 part of stabilizer and 55 parts of solvent.

[0022] Wherein, the preparation method of rosemary extract is as follows: 22 weight parts of collected rosemary leaves are washed and dried, pulverized, passed through a 40-mesh sieve, added with 60% ethanol solution, sealed, mixed and placed in ultrasonic cleaning In the device, take out after 15min of ultrasonic at room temperature, suction filtration, and the filtrate is obtained after rotary evaporation to dryness.

[0023] Wherein, the preparation method of ginkgo biloba extract is as follows: take 25 parts by weight of fresh ginkgo leaves, wash, dry, pulverize, pass through ...

Embodiment 2

[0030] Compared with Example 1, the selection of each raw material and the number of parts by weight are different, and the amount of each raw material and the preparation conditions are different in the preparation process. The preparation method refers to Example 1, and is specifically:

[0031] A sunscreen cosmetic prepared by weight of the following raw materials: 22 parts of rosemary extract, 25 parts of ginkgo biloba extract, 12 parts of propylene glycol, 3 parts of methylisothiazolinone, 8 parts of carbomer, urine 3 parts of capsules, 5 parts of sodium citrate, 6 parts of modified titanium dioxide particles, 8 parts of new UV absorber, 3 parts of stabilizer and 65 parts of solvent.

[0032] Wherein, the preparation method of rosemary extract is as follows: 25 parts by weight of collected rosemary leaves are washed and dried, pulverized, passed through a 40-mesh sieve, added with 60% ethanol solution, sealed, mixed and placed in ultrasonic cleaning In the device, take ou...

Embodiment 3

[0039] Compared with Example 1, the parts by weight of each raw material are different, and the amount of each raw material and the preparation conditions in the preparation process are different, and the preparation method thereof refers to Example 1, specifically:

[0040] A sunscreen cosmetic prepared by weight of the following raw materials: 20 parts of rosemary extract, 22 parts of ginkgo biloba extract, 11 parts of propylene glycol, 2 parts of methylisothiazolinone, 6 parts of carbomer, urine 2 parts of capsules, 4 parts of sodium citrate, 5 parts of modified titanium dioxide particles, 6 parts of new UV absorber, 2 parts of stabilizer and 60 parts of solvent.

[0041] Wherein, the preparation method of rosemary extract is as follows: 24 parts by weight of collected rosemary leaves are washed and dried, pulverized, passed through a 40-mesh sieve, added with 60% ethanol solution, sealed, mixed and placed in ultrasonic cleaning In the device, take out after 20min of ultras...

Abstract

The invention belongs to the technical field of cosmetics, and particularly relates to a sunscreen cosmetic. The sunscreen cosmetic is prepared from the following raw materials: a rosemary extract, a ginkgo leaf extract, propylene glycol, methylisothiazolinone, carbomer, allantoin, sodium citrate, modified titanium dioxide particles, a novel ultraviolet absorbent, a stabilizer and a solvent. The surfaces of prepared titanium dioxide nanoparticles are coated with a polyethylene glycol monomethyl ether polymer layer through ultrasonic adsorption, so that the titanium dioxide nanoparticles have better dispersity, and meanwhile, 2-hydroxy-4-methoxy-5-benzophenone sulfonate is grafted to a polyethylene glycol monomethyl ether polymer chain to obtain the novel ultraviolet absorbent. And the prepared modified titanium dioxide particles have good integration, and a physical and chemical dual sunscreen mechanism is formed.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen cosmetic. Background technique [0002] Ultraviolet light is the most energetic part of the solar spectrum that reaches the Earth's surface and lies between wavelengths 100-400nm. They are usually subdivided into three regions: UVA (400-320nm), UVB (320-280nm) and UVC (280-100nm). Among them, UVC radiation is almost completely absorbed and scattered by the atmosphere and cannot reach the ground. UVB-mediated 7-dehydrocholesterol is the precursor of vitamin D, which can meet more than 90% of the human body's vitamin D needs. Therefore, appropriate UV irradiation is beneficial to the synthesis of vitamin D and prevents the occurrence of bone diseases and osteoporosis. [0003] However, due to the severe destruction of the earth's ozone layer, the amount of ultraviolet radiation reaching the ground has increased sharply, posing a great threat to people's ...
