Embodiment 1

[0031] The preparation method of the vine tea extract of the present invention: grind the dry leaves of the vine tea into powder, reflux extraction with 12 times of 50% ethanol in a water bath for 2 hours, concentrate under reduced pressure to recover ethanol, and stand still to obtain brown-red crystals. Heat and dissolve the crystals with 95% ethanol, decolorize with activated carbon, concentrate to remove part of the ethanol, add 2 to 3 times the water of the raffinate, stand still, filter, and dry to obtain the vine tea extract, which is ready for use.

Embodiment 2

[0033] Compared with Example 1, the only difference is that in this example, 10 times of 60% ethanol water bath was used for reflux extraction for 1 h.

Embodiment 3

[0035] Compared with Example 1, the only difference is that in this example, 15 times of 40% ethanol water bath was used for reflux extraction for 3 hours.

Abstract

The invention discloses an antiaging sunscreen cream containing natural plant active ingredients. The antiaging sunscreen cream is prepared by using three components including A, B and C, wherein the component A contains 2-8 parts of stearic acid, 1-3 parts of C18 alcohol, 4-8 parts of isopropyl palmitate, 0.5-2 parts of lanolin, 0.1-0.5 part of Tween-60, 0.05-0.25 part of methylparaben and 35-45 parts of deionized water by weight; the component B comprises 0.2-0.8 part of triethanolamine, 6-10 parts of glycerol, 0.5-3 parts of Span-60, 0.2-0.8 part of EDTA (Ethylene Diamine Tetraacetic Acid), 0.5-2 part of azone and 28-35 part of deionized water by weight; and the component C comprises 0.15-0.35 part of vine tea extract, 0.2-0.4 part of licorice extract and 1-3 parts of camellia oleifera seed oil by weight. The antiaging sunscreen cream has a broad-spectrum, stable and strong absorption effect on ultraviolet rays and in particular obtains strong absorbing performance to the ultraviolet rays UVA; meanwhile, the antiaging sunscreen cream also has very good moisturizing, hydrating and antiaging effects on skins.

Description

technical field [0001] The invention relates to an anti-aging sunscreen containing natural plant active ingredients and a preparation method thereof, belonging to the technical field of daily chemical industry. technical background [0002] Solar radiation refers to the continuous electromagnetic radiation reaching the earth's surface, including part of ultraviolet light and visible light, wherein the wavelength of visible light is 400nm-800nm, and the wavelength of ultraviolet light is 200nm-400nm. The skin science community divides ultraviolet rays into short-wave ultraviolet rays (UVC, 200nm-280nm), medium-wave ultraviolet rays (UVB, 280nm-320nm) and long-wave ultraviolet rays (UVA, 320nm-400nm). [0003] In the UV and visible light spectrum, the longer the wavelength, the stronger the penetrating power; the shorter the wavelength, the stronger the energy, and the easier it is to cause skin lesions. Among them, UVC has the strongest killing ability to living cells, but i...
