Embodiment 1

[0020] Put 5 grams of kaempferen volatile oil, 1.5 grams of bellflower extract, 3 grams of astaxanthin, 2.5 grams of shea butter and 88 grams of deionized water in a mixer, stir and mix evenly, and the sunscreen that absorbs ultraviolet rays can be obtained combination.

[0021] UV protection test:

[0022] Measured by QB / T2410-98 "Measurement method for UVB sunscreen skin care effect of sunscreen skin care products - ultraviolet absorbance method", the relevant data are as follows in Table 1:

[0023] Table 1

[0024]

[0025]

[0026] As can be seen from the data in Table 1, the sunscreen composition of Example 1 is significantly higher than TiO to the blocking rate of ultraviolet rays. 2 , the blocking rate of ZnO to ultraviolet rays, indicating that the sunscreen composition of the present invention has excellent sunscreen efficacy.

Embodiment 2

[0028] Preparation of segregation cream:

[0029] 3 kg glyceryl stearate / PEG-100 stearate, 2 kg cetearyl alcohol, 6 kg squalane, 2.5 kg dimethicone, 4 kg caprylic / capric triglyceride , 1.2 kg of polyacrylamide, 0.1 kg of methylparaben, 0.1 kg of propylparaben, and 10 kg of sunscreen composition are mixed and put into an oil phase pot, heated and stirred to 85 degrees, stirred and dissolved completely, and 0.02 kg of sodium hyaluronate, 8 Mix kilograms of glycerin, 1.8 kilograms of tocopherol, 0.5 kilograms of carbomer, and 55.78 kilograms of deionized water into the water phase pot, heat and stir to 85 degrees, stir and dissolve completely, preheat the emulsification pot to 65 degrees, and stir at a speed of 50 rpm , first pump in the water phase, then pump in the oil phase, stir for 30 minutes, keep the temperature at 85 degrees, cool down to 45 degrees, add 5 kg of titanium dioxide, keep stirring for 10 minutes, cool to 40 degrees and discharge.

Embodiment 3

[0031] Preparation of sunscreen:

[0032] Heat 4 kg of glyceryl stearate, 15 kg of ethylhexyl hydroxystearate, 3 kg of sorbitan oleate and 15 kg of sunscreen composition to 85 degrees, stir until completely dissolved, and 7 kg of hydroxyethyl urea , 0.4 kg of xanthan gum, and 55 kg of deionized water are heated to 85 degrees, stirred until completely dissolved, the oil phase and the water phase are stirred and mixed, and then 0.4 kg of phenoxyethanol and 0.2 kg of essence are added, stirred and mixed to obtain sunscreen.

Abstract

The invention discloses a sun-resistant composition capable of absorbing ultraviolet rays. The composition comprises the following components: an ultraviolet adsorbent, an anti-inflammatory agent, anantioxidant and a wetting agent, wherein the ultraviolet adsorbent comprises one or more than one of rhizoma kaempferiae volatile oil, an alpinia japonica extract, ultrafine titanium dioxide or an evening primrose seed meal extract. Through synergistic effect of the components, the composition can effectively ultraviolet rays and achieve the sun-resistant effect, also can reduce skin damage symptom caused by ultraviolet irradiation, and has remarkable skin-care effect.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a sunscreen composition for absorbing ultraviolet rays. Background technique [0002] With the global atmospheric ozone depletion in recent years, the atmospheric ozone layer has been severely damaged, and the intensity of solar ultraviolet radiation has increased. UVB is an ultraviolet light with a wavelength of 315-280nm. Most of this type of ultraviolet light is absorbed by the epidermis of the skin. Due to its high energy level, it can cause strong photodamage to the skin, which can cause skin redness, blisters, inflammation, skin aging and other symptoms. UVA is ultraviolet rays with a wavelength of 400-315nm, which can reach deep into the dermis and act on the melanin in the epidermis, causing the skin to darken, which is one of the causes of skin aging and serious damage. With the strengthening of people's awareness of the hazards of ultraviolet rays and self-protection, people's...
