Description

A kind of Whitening sunscreen cream and preparation method thereof

Technical field

The present invention relates to a kind of sunscreen cream, relate in particular to a kind of Whitening sunscreen cream.

Background technology

Ultraviolet in sunlight is to cause skin blackening and aging main cause, conventionally resists ultraviolet by the mode of smearing sunscreen cream to skin.The action principle of sunscreen cream is that skin and ultraviolet are kept apart, thereby prevents skin sunburn.

Margarita is exactly classical beauty treatment medical material since ancient times, the successive dynasties medical science monumental works such as Compendium of Material Medica, " Mingyi Bielu ", " opening precious vegetation " all point out Margarita by calming the nerves, detoxify, preserve youthful looks, the effect such as correcting and skin moisturizing and rejuvenating, make skin gloss pure white, its beauty treatment mechanism is aminoacid and the trace element that contains various needed by human body in Margarita, its nutritional labeling and the required nutrient of mankind's skin approach, be easy to be absorbed by the body, there is the effect of good aesthetic health care and slow down aging.The Margarita powder that Margarita processes from strand is the most general a kind of mode of application pearl cosmetic.Margarita powder can solve face oil and dead bark problem, specifically, can play skin whitening, antidotal effect by the activity of enhancement of SOD, and therefore, Margarita powder can be used as a kind of additive of sunscreen cream, plays the auxiliaring effect that moistens whitening.

In Bombyx bombycis, containing abundant sericin composition is a kind of nature moisturizing factor material, containing 18 seed amino acids, there is good nutritive value and high medical value, can effectively prevent that scaly dry skin crowfoot cracks are aging, the melanin suppressing in skin generates, skin is had to good performance of keeping humidity and skin moistening effect, and also there is following function: thus antioxidant activity, suppress that TYR enzyme check melanin forms, activating skin cell, promote regeneration, anti-ageing cosmetology effect of waiting for a long time of cell.Sericin wherein can make skin keep certain moisture, there is characteristic and the skin moisture-keeping functions of stronger decomposition free radical activity, and possess the function to body-care such as antibacterial, anti-ultraviolet, antioxidation, generation that can also check melanin, delaying skin is wrinkling aging.

Summary of the invention

The object of the invention is to design a kind of Whitening sunscreen cream, this product contains the sericin in the Bombyx bombycis extracting by ad hoc approach, and add Margarita powder, be equipped with glycerol, iso-octyl palmitate, xanthan gum, isopropyl myristate, bisabolol, methyl glucoside sesqui-stearate, vitamin E, titanium dioxide, phenoxyethanol simultaneously and make novel sun cream product, it has the smooth exquisiteness of the skin of allowing, remove free radical, keep the skin wet and the effect such as collagen protein.

Technical scheme of the present invention is as follows:

A kind of Whitening sunscreen cream, is prepared from by the component of following weight percentage ratio:

Sericin 3～5%, Margarita powder 2～4%, glycerol 4～7%, iso-octyl palmitate 1～5%, xanthan gum 2～3%, isopropyl myristate 1～7%, bisabolol 4～5%, methyl glucoside sesqui-stearate 1～5%, vitamin E2～10%, titanium dioxide 3～6%, phenoxyethanol 2～5%.

Surplus is water.

Preferred each weight percentages of components is:

Sericin 4%, Margarita powder 3%, glycerol 6%, iso-octyl palmitate 2%, xanthan gum 2%, isopropyl myristate 2%, bisabolol 3%, methyl glucoside sesqui-stearate 3%, vitamin E 8%, titanium dioxide 5%, phenoxyethanol 4%.Surplus is water.

Preparation method, comprises the steps:

(1) prepare Margarita powder

Grind Margarita with grinder, obtaining fineness is 1000 object Margarita powder.

(2) prepare sericin

The silkworm cocoon that dries is pulverized, raw material fragment be impregnated in water, boil, in the time that liquor capacity is concentrated into original 20%, stop heating, be cooled to room temperature.In solution, add neutral protease to carry out enzymolysis, hydrolysis temperature is 20-35 DEG C, and pH value is 6-8, continues enzymolysis 2h, then solution is heated to boiling and maintains 30min, and enzyme denaturing is lived.Undissolvable silkworm silk residue is pulled out, and washed with water 2-5 time, and washings are merged in hydrolyzed solution.The heating of sericin hydrolyzed solution is concentrated into 30% of original volume, obtains the concentrated solution of sericin.Then 95% ethanol that adds same volume in sericin bioactive peptide solution, fully mixes 5-30min, makes sericin bioactive peptide flocculation sediment, and collecting precipitation filters, and vacuum drying, to constant weight, is crushed to 500 orders, obtains silk glue protein.

(3) finished product preparation.

A. in main mulser, Margarita powder, sericin aqueous solution are heated to 70-80 DEG C;

B. in oil phase pot, glycerol, iso-octyl palmitate, xanthan gum, isopropyl myristate, methyl glucoside sesqui-stearate, titanium dioxide are heated to 80-85 DEG C to the complete melting of each composition;

C. under room temperature, prepare bisabolol, vitamin E, phenoxyethanol aqueous solution.

Open vacuum pump by the main mulser of solution suction in oil phase pot, fully stir, be cooled to 50 DEG C, add bisabolol, vitamin E, phenoxyethanol aqueous solution, continue to stir 1h, after blowing, ageing 24 hours, after the assay was approved, fill obtains finished product.

And body embodiment

Embodiment: a kind of Whitening sunscreen cream preparation method

(1) prepare Margarita powder

Select high quality pearl, with grinder grinding, obtaining fineness is 1000 object Margarita powder.

(2) prepare sericin

The silkworm cocoon drying is pulverized to the fragment for 1mm size, then measure the distilled water of 30 times of quality of husks husk as raw material, raw material fragment be impregnated in aqueous solution, make its abundant swelling 40min, then under normal pressure, boil, the sericin part in raw material is eluted in solution, and to a certain degree hydrolysis, when solution be concentrated into original volume 20% time, stop heating, be cooled to room temperature.In solution, add the neutral protease of husks shell 2.0% quality to carry out enzymolysis, hydrolysis temperature is 25 DEG C, and pH value is 7.0, continues enzymolysis 2h, makes the sericin in solution be hydrolyzed to the active sericin that mean molecule quantity is 10000-20000Da.Then solution is heated to 100 DEG C and maintains 25min, enzyme denaturing is lived.Undissolvable silkworm silk residue is pulled out, and with a small amount of distilled water wash 3 times, and washings are merged in hydrolyzed solution.Silkworm silk is dried to constant weight at 60 DEG C of temperature, weigh silkworm silk, cocoon husk as raw material weight is deducted to silkworm silk weight, can calculate the sericin quality of dissolving in eluent.Sericin hydrolyzed solution is heated at 80 DEG C of temperature, be concentrated into 1/3 of original volume, naturally cool to after room temperature, obtain the concentrated solution of sericin.Then 95% ethanol that adds same volume in sericin bioactive peptide solution, fully mixes 20min, makes sericin flocculation sediment, and sedimentation and filtration is collected, and vacuum drying, to constant weight, is crushed to 200 orders, obtains sericin.

(3) finished product preparation.
