Refreshing and lasting sunscreen cream and preparation method thereof

Abstract

The invention discloses refreshing and lasting sunscreen cream. The refreshing and lasting sunscreen cream comprises the following raw materials in parts by weight. 10-15 parts of a highland barley extract, 10-15 parts of a sweet potato vine extract, 5-10 parts of a white willow bark extract, 3-5 parts of pullulan, 3-5 parts of pentapeptide-34 trifluoroacetate, 0.5-1 part of dipotassium glycyrrhizinate, 0.5-1 part of allantoin, 1-1.5 parts of ethylhexylglycerin, 1-2 parts of walnut oil, 1-5 parts of butanediol, 0.5-1.2 parts of cetostearyl alcohol,1-5 parts of nanometer titania, 0.1-0.3 part of spice, 0.01-0.05 part of a preservative, 1-5 parts of an emulsifying agent, and 55-65 parts of deionized water. According to the sunscreen cream, the plant extracts namely the highland barley extract, the sweet potato vine extract and the white willow bark extract, are added to effectively absorb ultraviolet rays and prevent skin from being sunburnt, through synergistic effect of a physical sunscreen agent namely the nanometer titania, and skin intolerance caused by adding of a chemical sunscreen agent is avoided, and the pullulan and the pentapeptide-34 trifluoroacetate are also added; andtherefore, the action time of the plant extracts and the nanometer titania on the surface of the skin is prolonged, the sunscreen time is longer, and besides, the use skin feeling of the sunscreen cream is improved.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a refreshing and long-lasting sunscreen and a preparation method thereof. Background technique [0002] With the increasingly serious environmental pollution, the ozone layer is gradually thinning, and the ultraviolet rays reaching the ground are increasing. The damage of ultraviolet rays to human skin has attracted more and more attention. Ultraviolet rays can not only increase the skin temperature through its thermal radiation effect, but also dilate the capillaries. Congestion, increase the evaporation of epidermal water, etc., directly cause adverse effects on the skin, accelerate skin aging, and also cause skin pigmentation, forming various spots such as freckles and chloasma, which in turn affect people's appearance. Therefore, in order to reduce the harm caused by ultraviolet radiation, sun protection is particularly important. [0003] Sunscreen refers to cosmetics that add suns...

Problems solved by technology

Physical sunscreens use fine particles to reflect ultraviolet light, such as commonly used fine particles such as titanium dioxide and zinc oxide. It is safer to choose physical sunscreens for sensitive skin, but there are many problems with physical sunscreens, such as easy Whitening, if the content of titanium dioxide is high, the skin will become whiter after use, it will be unnatural after application, and the smear feeling of physical sunscreens is not good, because physical sunscreens are all powder particles, unlike chemical sunscreens, which are more durable. poor skin feel
