Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a blueberry anthocyanin sunscreen composition, a sunscreen mud cream and a preparation method thereof.
Background
Ultraviolet rays in sunlight are electromagnetic waves having a wavelength shorter than that of visible light. Ultraviolet rays absorbed by the skin can damage DNA, so that wrinkles, sunburn, cataracts, skin cancer, even visual damage, immune system damage and other diseases can be caused. According to different actions of ultraviolet rays on organisms, the ultraviolet rays are medically divided into different wave bands: the wavelength of 320-400nm is the UVA wave band, and ultraviolet rays in the wave band have strong penetrating power and can directly reach the dermis layer of the skin to damage elastic fibers and collagen fibers, so that the skin is tanned and wrinkles are generated; the wavelength of 280-320nm is UVB wave band, ultraviolet rays in the wave band have erythema effect on human bodies, and long-term or excessive irradiation can cause skin to be suntan and cause red swelling and desquamation. In recent years, with the increasing awareness of people on protection from ultraviolet rays, people have attracted public attention to sun protection of skin, and people have increasingly demanded sun protection cosmetics.
Sunscreen cosmetic is a cosmetic added with sunscreen agent capable of blocking or absorbing ultraviolet rays to prevent skin from suntan and sunburn. Sunscreen cosmetics are various in types, and are generally classified into emulsion type and non-emulsion type in terms of formulation. At present, most of sunscreen products on the market at home are emulsified, and sunscreen cream, sunscreen milk, sunscreen gel and the like are common.
CN103202783A discloses a sunscreen cream and a preparation method thereof, which contains a physical sunscreen agent nano-scale titanium dioxide, a polymethylsilsesquioxane coated chemical sunscreen agent ethylhexyl methoxycinnamate, a polymethylsilsesquioxane coated chemical sunscreen agent bis-ethylhexyloxyphenol methoxyphenyl triazine and other UVB sunscreens, UVA sunscreens, additives and the like.
CN102008403A discloses a sunscreen oil, which contains dimethyl silicone oil, vaseline, olive oil, benzyl salicylate, peppermint oil and the like, is a non-emulsified sunscreen product, has a simple preparation process, has the characteristics of good waterproofness, easiness in spreading and the like, but is all grease components, is sticky and heavy, has poor moisturizing performance and is easy to cause skin pore blockage.
CN105662920A discloses a refreshing and low-irritation sunscreen oil and a preparation method thereof, wherein the sunscreen oil comprises polydimethylsiloxane, olive oil, rose hip oil, shea butter, tocopherol acetate, octyl p-methoxycinnamate, menthol anthranilic acid and mint essential oil, however, the refreshing property of the sunscreen oil mainly comes from the refreshing feeling brought by the mint essential oil, and is not a true refreshing and low-sensitivity formula, so that the sunscreen oil is also easy to cause skin pore blockage and acne.
Therefore, it is very meaningful to develop a sunscreen product which is truly green and natural, has no burden on the skin, and has a remarkable sunscreen effect.
