Embodiment 1

[0048] Prepare phases A, B, C, and D according to the weight percentages described in the above basic formula (the total weight of the sunscreen is 1kg for preparation). First heat the material of phase A to 50°C in a stainless steel pot, then place it in a 10-liter stainless steel high-speed homogeneous mixer with heating, and mix the material of phase B (the amount of NCC is 3%, Based on the total weight of the sunscreen), phase C (the amount of nano-titanium dioxide dispersion is 6.5%, based on the total weight of the sunscreen) materials are slowly added to the materials of phase A, after the materials of phases A, B, and C are mixed evenly , then add the D phase material, continue to stir at the same speed for 30 minutes, then remove the total material, place it in a 20MPa high-pressure homogenizer for treatment, and obtain a sunscreen containing NCC and nano-titanium dioxide. The sunscreen is sterilized at a constant temperature of 95° C. for 2 hours, cooled naturally to...

Embodiment 2

[0050] According to the formula and operating method of Example 1, wherein the NCC consumption in phase B is adjusted to 4% (based on the total weight of sunscreen), the amount of nano-titanium dioxide dispersion in phase C is adjusted to 5.5% (based on the total weight of sunscreen) count), get sunscreen.

Embodiment 3

[0052] According to the formula and operating method of Example 1, wherein the NCC consumption in phase B is adjusted to 1% (based on the total weight of sunscreen), and the amount of nano-titanium dioxide dispersion in phase C is adjusted to 8.5% (based on the total weight of sunscreen) count), get sunscreen.

Abstract

The invention discloses a sunscreen cream cosmetic composition containing nano crystal cellulose. The sunscreen cream cosmetic composition comprises the nano crystal cellulose and nano titanium dioxide. The sunscreen cream cosmetic composition is used for a sunscreen cream, is capable of preventing ultraviolet irradiation in a UVA (Ultraviolet A) region being 320-400nm and a UVB (Ultraviolet B) region being 280-320nm, and is high in sunscreen efficiency; and the sun protect factor (SPF) value is more than 15. The sunscreen cream is safe for a human body without toxicity, and can be suitable for being used by various kinds of persons.

Description

technical field [0001] The present invention relates to a sunscreen cosmetic composition. Background technique [0002] Sun protection products (such as sunscreen) are skin care products that block the ultraviolet rays in the sun's rays from the human skin. There are many forms of sunscreen. For example, physical sunscreen is to add sunscreen particles in sunscreen, which can absorb and reflect ultraviolet rays, so as to play a role in sun protection; chemical sunscreen is to add certain chemical substances to absorb ultraviolet rays. ; Biological sunscreen is to penetrate certain chemical substances into the nucleus of skin cells to protect cell DNA, thereby achieving the purpose of preventing ultraviolet damage; medicinal sunscreen uses Chinese herbal ingredients to absorb ultraviolet rays, thereby achieving a sunscreen effect. Although some compounds can prevent ultraviolet rays from harming the skin, they also have side effects on the skin, causing damage to the skin fr...
