Embodiment 1

[0019] Enzymatic hydrolysis of wood frog oil to produce collagen peptides: Weigh dry wood frog oil, soak in 100 times distilled water at 4°C for 12 hours; grind and homogenize; heat in a boiling water bath, and heat-treat at 90°C for 10 minutes to obtain a suspension solution; cool the suspension to 60°C; add 5% protease by weight of dry Rana oil; at 70°C and pH 7, perform enzymolysis in a constant temperature water bath for 6 hours, accompanied by magnetic stirring during the process; after enzymolysis, Inactivate the enzyme at 85°C for 15 minutes; cool to room temperature to obtain the collagen peptide of Rana oil.

[0020] Rana oil collagen peptide-coated nano-titanium dioxide: Weigh a certain amount of titanium sulfate and prepare a 1.2mol / L titanium sulfate solution; take the prepared titanium sulfate solution, add Rana oil hydrolyzate at a volume ratio of 4:1, and add Mix a certain amount of urea; heat in a water bath at 80°C for 5 hours with slow stirring; after the rea...

Abstract

The invention relates to rana japonica oil collagen peptide moisturizing sun cream and a preparation method thereof and belongs to the technical field of preparation of cosmetics. The invention discloses physical sun cream containing rana japonica oil collagen peptide. The physical sun matter comprises nano titanium dioxide and zinc oxide which can prevent ultraviolet irradiation in the long-wavelength region. The sun protection factor of the sun cream is relatively high (SPF is greater than 15) and long in sunscreen time, and has the characteristics of uniform smearing, harmlessness and safety to human body and skin protection such as moisturing and crease resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of cosmetics production, and relates to a method for making moisturizing sunscreen by using wood frog oil collagen peptide as a raw material. Background technique [0002] With the deterioration of the environment, the threat of ultraviolet rays to human skin is becoming more and more serious. Medical research has found that long-term exposure to ultraviolet rays can cause epidermal cell damage, pigmentation, and severe skin cancer. Ultraviolet rays can be divided into near-ultraviolet UVA region (320nm-400nm), far-ultraviolet UVB region (280nm-320nm) and ultra-short ultraviolet UVC region (200nm-280nm) according to wavelength. UVA is the main culprit that causes harm to the skin. UVA can enter the dermis, destroy collagen, elastic fibers, etc., cause skin aging, produce fine lines, and melanin deposition; UVB can cause skin erythema or blisters, etc., increase melanin deposition, through Appropriate shiel...
