Abstract
The invention relates to silk-extract-containing sunscreen skincare emulsion and a preparation method thereof. The emulsion is characterized by being prepared from the following raw materials at weight ratio: 51.3%-76.9% of deionized water, 0.1%-15.0% of silk extract, 6.0%-8.0% of C12-C15 alkyl benzoate, 4.5%-6.0% of glycerin, 4.0%-6.0% of isopropyl myristate, 2.5%-4.0% of dicaprylyl carbonate, 2.5%-3.0% of cyclic poly(dimethylsiloxane), 1.5%-3.0% of C12-20 alkyl glucoside, 0.4%-0.8% of methyl hydroxybenzoate, 0.4%-0.8% of ethyl hydroxybenzoate, 0.6%-0.8% of panthenol, 0.3%-0.5% of allantoin, 0.1%-0.3% of ethylenediaminetetraacetic acid (EDTA) disodium, 0.1%-0.3% of dehydroxanthan gum and 0.1%-0.2% of essence. The sunscreen skincare emulsion obtained by the method is used safely and effectively.
Description
Technical field
The present invention relates to skin care field, relate in particular to a kind of silkworm silk extract sun-proof skin care breast and preparation method thereof.
Background technology
At present commercially available its sun-prevention component of sunlight screening skin-protecting product all is made up of chemical sunscreen nano grade inorganic metallic oxide opaque (like the titanium dioxide) sun-prevention component of accompanying.Current research shows, with these sun-proof raw materials certain risk is arranged, and the big more risk of consumption is big more.Fact proved that chemical sunscreen makes responsive skin matter allergic symptom occur usually, and normal skin matter is had obvious stimulation; Nano grade inorganic metallic oxide opaque sun-prevention component usually can stop up pore, influences skin eupnea and perspire, and then causes the hair follicle inflammation, does not also get rid of the probability of severity of symptoms.
The patent No. is 200910101948.5, and name is called that to disclose chemical sunscreen 4-methoxy cinnamic acid-2-ethyl hexyl ester and the benzophenone-3 listed in a kind of " cosmetics health standard " of issuing in January, 2007 with the People's Republic of China (PRC) in the Chinese patent of " a kind of sericin whitening sun protection emulsion and preparation technology thereof " be sun-proof whitening emulsion prescription and the preparation technology master, that contain sericin.Use sericin solution that soda dissolving sericin makes alkaline solution in this patent as pH10; Do not mention neutralization in the patent; Directly be used for manufacturing skin care item with such material liquid and can have potential safety hazard, be coated onto on the skin after, along with the evaporation of moisture; Alkaline components is by highly concentrated, and skin can come to harm.In addition, directly the cocoon shell is dissolved and take, sanitary index, sericin purity all is difficult to guarantee, because higher content of beary metal is arranged in the sericin, should not directly be used for cosmetics.And the sericin liquid that obtains like this is also very unstable, is easy to degeneration, becomes insoluble frozen glue.So there is bigger query in this practical applicability, and the ultra light sun block lotion that this method is made still contains chemistry (synthesize) component of sun, safety in utilization still remains raising.
Summary of the invention
Technical problem to be solved by this invention be overcome deficiency of the prior art and provide a kind of and human skin affine the close friend's and to have a silkworm silk extract sun-proof skin care that does not contain chemistry (synthesize) sunscreen and the sun-proof powder body of inorganic, metal oxide that intercepts the ultraviolet radiation characteristic newborn; During the present invention clearly comes to replace fully at present both at home and abroad cosmetic product with the silkworm silk extract as the sun-prevention component of Environmental Safety in employed, the international cosmetic material catalogue and chemistry (synthesizing) sunscreen and inorganic, metal oxide opaque (metal oxides such as titanium dioxide) sunscreen listed in People's Republic of China's " cosmetics health standard " of issuing in January, 2007; Make the sun-proof skin care product that makes both safe and effective; Promote quality again, obtain distinctive, the general soft and smooth comfortable skin sense of silk simultaneously.
The technical scheme that the present invention solves the problems of the technologies described above employing is: this silkworm silk extract sun-proof skin care breast is characterized in that comprising that following raw material and the shared weight ratio of each raw material are in the prescription:
Deionized water 51.3 %---76.9 %
Silkworm silk extract 0.1 %--15.0 %
C12 ~ C15 alcohol benzoate 6.0 %--8.0 %
Glycerol 4.5 %--6.0 %
Isopropyl myristate 4.0 %--6.0 %
Dicaprylyl carbonate 2.5 %--4.0 %
Cyclomethicone 2.5 %--3.0 %
C12-20 alkyl androstanediol 1.5 %--3.0 %
Methyl hydroxybenzoate 0.4 %--0.8 %
Ethyl hydroxybenzoate 0.4 %--0.8 %
Pantothenylol 0.6 %--0.8 %
Allantoin 0.3 %--0.5 %
EDTA disodium 0.1 %--0.3 %
Dehydrogenation xanthan gum 0.1 %--0.3 %
Essence 0.1 %--0.2 %.
Silkworm silk extract of the present invention is silkworm silk peptide and/or silkworm fibroin, and silkworm silk refers in particular to the silk without any processed of the initial conditions that Bombyxmori Linnaeus spues.
The silkworm silk extract can effectively intercept ultraviolet, and is especially to the ultraviolet of ultraviolet band medium wavelength 280nm-320nm, promptly the strongest to the maximum UVB band ultraviolet obstructing capacity of human harm.No matter be to use a kind of silkworm silk peptide or silkworm fibroin separately, also be to use the mixture of silkworm silk peptide and fibroin albumen, can both effectively intercept ultraviolet.Great advantage of the present invention is fully need not chemistry (synthesizing) sunscreen and nano grade inorganic metal-oxide powder (like titanium dioxide) sunscreen; Eliminated those injuries of the sun-proof powder body of chemical sunscreen or nano grade inorganic fully, as made skin allergy, obstruction pore and the potential threat as latest report causes experiment mice heredity teratogenesis human body.
The chemistry sunscreen is the material that makes skin allergy easily, also has other potential harm, thus in cosmetics by the strictness use of limiting the quantity of.
The present invention also provides a kind of method for preparing of silkworm silk extract sun-proof skin care breast, it is characterized in that may further comprise the steps:
1) by proportioning C12-15 alcohol benzoate, isopropyl myristate, dicaprylyl carbonate, Cyclomethicone, C12-20 alkyl androstanediol, ethyl hydroxybenzoate, methyl hydroxybenzoate are heated to 80--85 ℃ in oil cauldron, stir;
2) by proportioning glycerol, pantothenylol, allantoin, dehydrogenation xanthan gum, EDTA disodium are added in the deionized water suction after the heating for dissolving and be preheated in 80-85 ℃ the emulsifying pot, stir;
3) while stirring that step 1) is made oil soluble material adds in the emulsifying pot, continues to stir 5-10 minute;
4) vacuum emulsifying 3-5 minute;
5) stirring is cooled to 45-55 ℃, adds the silkworm silk extract by proportioning, and essence stirs;
6) discharging;
7) fill, packed products.
The present invention compared with prior art has the following advantages: be that fibroin is degraded into peptide or becomes fibroin albumen; Purifying and controlling molecular weight makes the ultraviolet ability of obstruct reach best; Simultaneously can conveniently process powder takes at any time; The material liquid of gained is stable before and after the powder process, and invariance can together be used with numerous cosmetic materials.The sun-proof skin care breast and the affine close friend of human skin that process, safe in utilization effective, obtain the general soft and smooth comfortable skin sense of distinctive silk simultaneously.
