Description

Suncream
Technical field
The present invention relates to cosmetic technical field, more particularly, to a kind of suncream.
Background technology
Skin plays the role of barrier protection to human body, it make in vivo it is various tissue and organ from physical, mechanicalness, Chemically with the invasion and attack of pathogenic microorganism.Human skin, especially skin of face often expose to the open air outside, are easily subject to the external world to invade Evil.After skin receives ultraviolet overexposure, epidermal cell can be damaged, activates Tyrosinase, accelerates pigment synthesis, destroys skin The moisture-keeping functions of skin, make skin become drying, and the elastic fibers allowed in skin corium is damaged, and produces microgroove, under acute irradiation, Skin inflammation can also be caused, burnt.Even in extreme circumstances, it is also possible to pigmentosa cutaneum carcinoma etc. can be become.Therefore, it is daily In life, people are more and more vigorous to sun-proof demand.
The sun-proof principle of sunscreen product mainly has two kinds:Physical sunscreen and chemical sunscreen.Physical sunscreen is former using physics Reason progress is sun-proof, is mainly used for reflecting sunlight, achievees the purpose that sun-proof;Chemical sunscreen is mainly absorbed purple using chemical composition Outside line, and then carry out sun-proof.Existing sunscreen product is only capable of respite skin water shortage, has certain sun-screening function, but anti- Shine it is ineffective, and it is sun-proof while, skin injury can not be repaired, skin effect is poor.Therefore it is good to develop a kind of sun-proof result, And skin injury can be repaired at the same time, the suncream with skin-protecting function has great importance.
The content of the invention
In view of this, it is an object of the invention to provide a kind of suncream, the suncream can be achieved sun-screening function, at the same time Skin injury can also be repaired, promotes dermal cell growth, there is preferable skin effect.
To achieve the above object, the present invention provides a kind of suncream, it includes umbilical cord stem cells extract, oat peptide, Wild soybean peptide, moisturizer, thickener, plant extracts, nano particle and solvent.
Preferably, based on the suncream of 100 parts by weight, the content of the umbilical cord stem cells extract is 0.5- 1.5 parts by weight, the content of the oat peptide are 1-2 parts by weight, and the content of the Wild soybean peptide is 1-3 parts by weight, the moisturizing The content of agent is 5-8 parts by weight, and the content of the thickener is 6-8 parts by weight, and the content of the plant extracts is 1.5-3 weights Part is measured, the content of the nano particle is 3-6 parts by weight, and surplus is solvent.
Preferably, based on the suncream of 100 parts by weight, the content of the umbilical cord stem cells extract is 0.8- 1.2 parts by weight, the content of the oat peptide is 1-1.5 parts by weight, and the content of the Wild soybean peptide is 1.5-2 parts by weight, described The content of moisturizer is 6-7 parts by weight, and the content of the thickener is 6.5-7.5 parts by weight, the content of the plant extracts For 1.8-2.5 parts by weight, the content of the nano particle is 4-5 parts by weight, and surplus is solvent.
Preferably, the moisturizer is selected from least one of hyaluronic acid, glycerine, butanediol.
Preferably, the plant extracts be selected from turmeric root extract, Thymus serpyllum extract, Fructus Cucumidis sativi extract and At least one of peppermint leaf extract.
Preferably, antioxidant is further included, based on the suncream described in 100 parts by weight, the antioxidant contains Measure as 1-3 parts by weight.
Preferably, the antioxidant is at least one in vitamin E, ascorbic acid, cocoa extract, caffeine Kind.
Preferably, the nano particle is selected from Al2O3、SiO2、TiO2、ZnO、ZnS、BaSO4In one or more;Institute The particle diameter for stating nano particle is 50-500nm.
Preferably, the solvent is deionized water or ethanol.
The suncream provided according to the present invention, contains nano particle in the suncream, it can be achieved that physical sunscreen function, together When, also contain umbilical cord stem cells extract in suncream provided by the invention, it is with powerful cell tissue repair function, energy Skin injury is enough repaired, promotes dermal cell growth, meanwhile, coordinate oat peptide, Wild soybean peptide and plant extracts, can be into one Step stimulates the division of skin base cell, softens tender skin, increases skin elasticity, enhances the skin effect of suncream.
The additional aspect and advantage of the present invention will be set forth in part in the description, and will partly become from the following description Obtain substantially, or recognized by the practice of the present invention.
