The chemistry of vitamin A is called retinol, is found vitamin the earliest.Vitamin A has two kinds.A kind of is retinol (retionl), is initial vitamin A form (only being present in animal food); Another kind is carotene (carotene), changes in vivo the preformation material (provitaminA can absorb from vegetalitas and animal food) of vitamin A into; The measurement unit of vitamin A is 3 kinds of USP unit (United States Pharmacopoeia), IU unit (International Units), RE units (Retinol Equivalents) etc.
Summary of the invention:
For the prior art above shortcomings, technical problem to be solved by this invention is to provide a kind of retinol protective skin cream.
Technical problem of the present invention is achieved by following technical proposals:
A kind of retinol protective skin cream, comprise the raw material of following weight portion: 0.4-0.6 part retinol, 0.3-0.7 part spermol, 8-12 part spermol lactate, 6-10 part glycerol, 2-3 part polysorbate60,50-80 part water.
Adopt the general protective skin cream preparation method in this area can make above-mentioned retinol protective skin cream.For example, oil phase retinol, spermol and spermol lactate mixed is heated to 65-85 ℃; The water that glycerol, polysorbate60 and water are mixed is heated to 65-85 ℃; Under agitation water is added in oil phase, be cooled to room temperature and can make retinol protective skin cream of the present invention.
Preferably,
A kind of retinol protective skin cream, comprise the raw material of following weight portion: 0.4-0.6 part retinol, 0.3-0.7 part spermol, 8-12 part spermol lactate, the agent of 6-10 part plant sun, 6-10 part glycerol, 2-3 part polysorbate60,50-80 part water.
The oil phase that retinol, spermol, spermol lactate and plant sun agent are mixed is heated to 65-85 ℃; The water that glycerol, polysorbate60 and water are mixed is heated to 65-85 ℃; Under agitation water is added in oil phase, be cooled to room temperature and can make retinol protective skin cream of the present invention.
Described plant sun agent is a kind of or its mixture in rutin, mulberrin and silymarin.
Described plant sun agent consists of by weight following component: rutin 1-3 part, mulberrin 1-3 part and silymarin 1-3 part.
Described rutin, English name: Rutin, CAS accession number: 153-18-4.
Described mulberrin, have another name called: Morusin, morindone C, Kuwanon C, chemical name: 4H-1-Benzopyran-4-one, 2-(2,4-dihydroxyphenyl)-5,7-dihy-droxy-3,8-bis (3-methyl-2-butenyl), CAS accession number: 62949-79-5 is documented in " active components of plants dictionary ".
Described silymarin, English name: Silybin, CAS accession number: 65666-07-1.
Obviously, according to specific needs, can also add in the present invention the raw materials such as wetting agent, antiseptic, essence, whitening agent, pigment and other functional additives.
Retinol protective skin cream of the present invention, have and regulate epidermis and the metabolic effect of horny layer, can defying age, and the wrinkle removing stricture of vagina; Can reduce seborrhea and make skin flexible, while spot fading, soft and moist skin.
The specific embodiment:
Following embodiment further illustrates of the present invention, rather than limits the scope of the invention.In the present invention, if no special instructions, each raw material all be take working substance content as 100%.
Embodiment 1
The oil phase that retinol, spermol and spermol lactate are mixed is heated to 70 ℃; The water that glycerol, polysorbate60 and water are mixed is heated to 70 ℃; In under continuous stirring condition, water being added to oil phase, stir, be cooled to room temperature and can make retinol protective skin cream of the present invention.

Along with people, to the intensification of ultraviolet harm understanding and the generally report of skin photoage problem, consumer is growing to the demand of sun-proof series products.Sunscreen is divided into Orangic sunscreen, inorganic sunscreen and natural plant sun agent.
The organic chemistry sunscreen easily infiltrates skin, and particularly the micromolecule after the degraded, easily be absorbed by the skin.Orangic sunscreen commonly used causes the common report of sensitization of skin phenomenon, and native land man is strictly regulated its use amount.
Inorganic sunscreen is generally metal-oxide, and main inorganic sunscreen has zinc oxide, titanium dioxide, zirconium oxide, silicon dioxide and iron sesquioxide etc.Inorganic sunscreen outward appearance and use skinfeel are poor, easily cause pore to stop up simultaneously.
Add the natural plant sun agent in embodiment of the present invention 2-5, safe and non-stimulating, can play effective anti-sunlight function, there is the skin repair of enhancing simultaneously and prevent and treat the effect of skin photoage.Especially, rutin, mulberrin and silymarin are composite, sun-proof performance Synergistic.
