[0039] Two) preparation and purification of dextran sucrase

[0040] Inoculate the Leuconostoc enterica stored in an ultra-low temperature refrigerator on a solid slant medium, activate it in a constant temperature incubator at 25°C for 24 hours, then inoculate it on a solid surface medium and culture it for 24 hours under the same conditions, and pick it up with an inoculation loop Inoculate a single colony on the seed medium, cultivate it to the logarithmic phase (about 20h) at 25°C under a 150r / min shaker, and inoculate it on the enzyme-producing medium at an inoculation amount of 2% (v / v) with a pipette , after culturing for 20 hours under the same conditions, at 4°C, 12,000 r / min high-speed refrigerated centrifugation for 20 minutes to obtain crude enzyme solution. Take 20mL of crude dextran sucrase enzyme solution and place it in a 50mL centrifuge tube, add 16mL of 50% (w / w) polyethylene glycol 6000 (PEG) solution, and make up to 40g with sterile water. After mixing tho...

Embodiment 1

[0058] The formula (percentage by weight) of sunscreen skin care cream: dextran 2%, sweet tea polyphenol 1.0%, lauryl lactate 10%, olive oil 10%, squalane 6%, methoxy ethylhexyl cinnamate 6% , zinc oxide 8%, glycerin 10%, butanediol 10%, EDTA disodium 0.05%, and the balance is deionized water; mass concentration 3% citric acid is used as a pH regulator. Among them, sweet tea polyphenols come from the sweet tea extract of Guangxi specialty Yaoshan sweet tea: sweet tea polyphenols ≥ 40%, Guangxi Guilin Jiqi Shili Natural Products Technology Co., Ltd.

[0059] The preparation method of sunscreen and skin care cream: mix lauryl lactate, olive oil, squalane, zinc oxide, and ethylhexyl methoxycinnamate in proportion, and stir continuously with a magnetic heating stirrer until the temperature rises to 70~ Make it fully melt or dissolve at 75°C to obtain the oil phase; take the formula amount of dextran and stir it evenly on a magnetic stirrer, then add the mixed solution of glycerin ...

Embodiment 2

[0061] The formula (percentage by weight) of sunscreen and skin care cream: 6% dextran, 0.5% sweet tea polyphenols, 10% lauryl lactate, 10% olive oil, 6% squalane, 6% ethylhexyl methoxycinnamate , zinc oxide 8%, glycerin 10%, butanediol 10%, EDTA disodium 0.05%, and the balance is deionized water; mass concentration 3% citric acid is used as a pH regulator.

[0062] Preparation method is the same as embodiment 1.

Abstract

The invention discloses a sunscreen skin care product additive which is dextran. Accordingly, the inventor also prepares a corresponding sunscreen skin care product and a preparation method thereof. The obtained product has the characteristics of being good in sunscreen effect and being safe, comfortable and non-irritant. Tests show that due to the unique function of the dextran, the sunscreen skin care product has the advantages of effectively relieving light aging of the skin and making up for the problems that the traditional sunscreen cream is strong in decorous feeling, easy in blocking of pores, irritant for skin, insufficient in persistence, low in comfort and the like; meanwhile, the moisture level of the product can be improved, so that the requirements of consumers can be met toa higher degree.

Description

technical field [0001] The invention belongs to the technical field of sunscreen skin care products, and in particular relates to a sunscreen skin care product additive, a sunscreen skin care product and a preparation method thereof. Background technique [0002] Scientific experiments have proved that long-term and high-dose ultraviolet radiation can cause cell reactions, change the structure or function of individual cell components, lead to the loss of intercellular information transmission and cell apoptosis, and even cause various skin diseases and skin cancer. Ultraviolet rays can be divided into three types according to different wavelengths, long-wave ultraviolet (UVA, wavelength between 315nm and 400nm, accounting for 90% to 99%); medium wave ultraviolet (UVB, wavelength between 280nm and 315nm, accounting for 1% to 10%) %); short-wave ultraviolet light (UVC, the wavelength is between 200nm and 280nm, very small amount). Human skin is composed of stratum corneum, e...
