Embodiment 1

[0029] Taking 100g sunscreen as an example in the present embodiment, the using method of almond oil and rutin composition in sunscreen is:

[0030]

[0031] The preparation method of above-mentioned sunscreen is:

[0032] Step 1: Prepare the oil phase

[0033] According to the above-mentioned ratio of parts by mass, first take almond oil and put it in a clean beaker, and add squalane, ethylhexyl palmitate, beeswax, vitamin E acetate, and Tween 80 into the beaker in turn while stirring continuously , heated to 70-75 ° C, in order to prevent deterioration of raw material components, to avoid excessive heating.

[0034] Step 2: Prepare the water phase

[0035] Then disperse the hydrophilic components, i.e. hyaluronic acid, rutin, propylene glycol, glycerol, 1,3-butanediol, disodium diethylamine tetraacetate, and Span 80, to the Place in another clean beaker in deionized water, heat to 70°C, stop heating and stir thoroughly to ensure that the added components are fully swol...

Embodiment 2

[0042] The present embodiment takes the preparation of 100g sunscreen as an example, and the method of using almond oil and rutin composition in the sunscreen is as follows:

[0043]

[0044] The specific preparation method is the same as in Example 1.

Embodiment 3

[0046] Taking 100g sunscreen as an example, the method of using almond oil and rutin composition in sunscreen lotion is as follows:

[0047]

[0048] The specific preparation method is the same as in Example 1.

[0049] In order to better understand the essence and beneficial effects of the present invention, the following will detect the physical and chemical properties of the sunscreen that has added almond oil and rutin composition, the ultraviolet radiation of the sunscreen containing almond oil and rutin composition Light absorption characteristics and the influence test on the activity of tyrosinase in human melanoma cells A875 damaged by ultraviolet rays, to illustrate its new application in the preparation of sunscreens.

[0050] 1. Physical and chemical performance testing

[0051] According to the test method and inspection rules stipulated in the light industry standard QB / T2266-1997 of the People's Republic of China in the emollient cream, the almond oil rutin ...

Abstract

The invention relates to application of composition of flat almond soil and rutin in a sun-screening agent. According to the invention, the composition comprises the following components in parts by mass: 5 to 15 parts of flat almond soil and 0.1 to 0.5 part of rutin. An experiment proves that the composition of the flat almond soil and the rutin can obviously inhibit the activity of tyrosinase in human melanoma cell A875 which is damaged by ultraviolet rays, and the composition also has the synergistic effect. The composition can be applied to the sun-screening agent as a natural additive; and moreover, the flat almond soil and the rutin are both natural products, are softer on the skin, and have no irritation; and the composition can play a role in screening the sun and caring the skin if being used for a long term.

Description

technical field [0001] The invention relates to a new application of almond oil and rutin composition in sunscreen. Background technique [0002] The field of cosmetics research pays more and more attention to the development of sunscreen skin care products, by applying sunscreen skin care products on the skin surface to avoid damage to the skin caused by excessive ultraviolet radiation during outdoor activities. Sunscreens currently on the market mainly achieve sunscreen effects by adding the following two sunscreen agents. [0003] (1) UV absorbers UV absorbers are usually aromatic compounds, which generally have a large conjugated structure or contain a large number of carbonyl groups. Rays with shorter wavelengths (250-340nm) in sunlight can be absorbed by single and double building blocks in the compound and released in the form of heat energy. UV absorbers often used in sunscreen skin care products include UVB absorbers (isooctyl methoxycinnamate, 4-methylbenzylidene...
