Embodiment 1-3

[0061] The following is a description of the raw material components and preparation process of the sunscreen composition containing inorganic sunscreen agents in Examples 1-3 of the present invention.

[0062] Example of preparation of new inorganic sunscreen

[0063] The preparation process of a new type of inorganic sunscreen agent (modified titanium dioxide) can be described as follows:

[0064] 1) Using tetrabutyl titanate as the titanium source, using an appropriate amount of concentrated nitric acid to control the pH value of the system, and synthesizing the titanium dioxide xerogel by the sol-gel method.

[0065] 2) Mix the titanium dioxide xerogel synthesized in the above steps with different nitrogen sources. The new inorganic sunscreen (modified titanium dioxide) in the present invention uses urea as the nitrogen source, and the titanium dioxide xerogel is uniformly mixed with urea. The content ratio of these is controlled between 1:4 to 1:3, and then a new inorganic sunsc...

Embodiment 1

[0067] A sunscreen composition containing a novel inorganic sunscreen agent, comprising the following raw material components in weight percentage:

[0068]

[0069]

[0070] The above-mentioned sunscreen composition containing a novel inorganic sunscreen agent is prepared by the following process steps:

[0071] 1) Add bis-ethylhexyloxyphenol methoxyphenyl triazine, stearyl alcohol, glyceryl stearate, beeswax, tocopherol acetate, and sorbitan stearate to the airtight emulsification pot, and heat up To 85-90℃, make it completely dissolve to obtain an oil phase mixture;

[0072] 2) Add a new type of inorganic sunscreen (modified titanium dioxide) to the above-mentioned mixed oil phase, and homogenize it with a homogenizer at about 80°C;

[0073] 3) While performing the above two steps, add sodium hyaluronate, glycerin, and panthenol to the water, stir, and heat to about 80°C for later use;

[0074] 4) Add the product in step 2) to step 3) for emulsification. The temperature is reduced t...

[0077] A sunscreen composition containing an inorganic sunscreen agent, comprising the following raw material components by weight percentage:

[0078]

[0079]

[0080] The above-mentioned sunscreen composition containing inorganic sunscreen agent is prepared by the following process steps:

[0081] 1) Add bis-ethylhexyloxyphenol methoxyphenyl triazine, stearyl alcohol, glyceryl stearate, beeswax, tocopherol acetate, and sorbitan stearate to the airtight emulsification pot, and heat up To 85-90℃, make it completely dissolve to obtain an oil phase mixture;

[0082] 2) Add unmodified titanium dioxide to the above-mentioned mixed oil phase, and homogenize it with a homogenizer at about 80°C;

[0083] 3) While performing the above two steps, add sodium hyaluronate, glycerin, and panthenol to the water, stir, and heat to about 80°C for later use;

[0084] 4) Add the product in step 2) to step 3) for emulsification. The temperature is reduced to 40 to 45°C and the flavor, iodopropynol butyl...

Abstract

The invention discloses a sunscreen composition containing a novel inorganic sunscreen agent. The sunscreen composition is prepared from the following ingredients in percentage by weight: a, organic ultraviolet protecting agents; b, the novel inorganic sunscreen agent; c, at least about 15 percent of water; d, an oil phase, containing ingredients in a liquid state at the normal temperature and water-insoluble ingredients in a solid state at the normal temperature. The sunscreen composition provided by the invention contains one inorganic metal oxide; the metal oxide is the metal oxide subjected to modification treatment; the sunscreen product containing the metal oxide has the high sunscreen index. The modified inorganic metal oxide provided by the invention can provide the high sunscreen index; the effective ultraviolet irradiation protection can be provided; the irritation and unclean feeling caused by an organic sunscreen agent is reduced; the damage to the skin caused by the self photocatalysis effect of the titanium dioxide is reduced; in addition, the skin damage caused by the sunscreen agent optical activity is reduced.

Description

Technical field [0001] The invention discloses a sunscreen composition, which contains a modified inorganic metal oxide. The sunscreen composition can effectively shield ultraviolet radiation, provide a high sun protection index, and reduce the photoactivity of the sunscreen The skin damage caused, while providing a refreshing and non-greasy feeling to the skin. Background technique [0002] Due to the short wavelength of ultraviolet light, high energy and strong destructive power, long-term exposure will not only cause skin damage and skin diseases, but also accelerate skin aging. In order to prevent skin damage and skin diseases, sunscreen products are more and more widely used. In the early days, organic compounds were mainly used as UV protective agents in cosmetics, mostly organic compounds such as benzophenones, anthranilones, salicylate, p-aminobenzoic acid, cinnamate, etc. It shields the damage of ultraviolet rays to a certain extent, but due to its instability, short l...
