Abstract
The invention discloses a kind of UVB ultra light sun block lotion and preparation method thereof, its composition comprises solid oils and fats, liquid fat, solid emulsifier, UVB section sunscreen, rheology control agent, antiseptic, essence, deionized water.The oil phase that its preparation method soon will be made up of solid grease, liquid fat, solid emulsifier, UVB section sunscreen, with be distributed to by rheology control agent the water of forming in the deionized water mix the back homogenizing, stir the cooling back and add antiseptic, essence, restir is cooled to room temperature and promptly obtains a kind of UVB ultra light sun block lotion of the present invention.Because the solid lipid microgranule that preparation process forms parcel sunscreen, reduced the stimulation that causes with contact skin, simultaneously, the nano-lipid microgranule that coats sunscreen itself has the ultraviolet shielded effect of certain physics, the effect of Synergistic can be played with the ultra-violet absorption effect of chemical sunscreen, skin tanning, sunburn, solarization pain that sun exposure causes can be prevented.
Description
Technical field
The present invention relates to a kind of UVB ultra light sun block lotion and preparation method thereof, belong to the cosmetics technical field.
Background technology
Raising along with people's living standard, people also constantly increase the demand of skin-protection health products, and the cosmetics with specific function are also had demand, sun care preparations is the cosmetics with sun-proof effect, and its major function and effect are the skin damage that prevents that the ultraviolet in the sunlight from causing the human body skin irradiation; In recent years, people have had further raising to ultraviolet understanding, especially to the re-recognizing of ultraviolet light,long wave, make people pay close attention to the injury of ultraviolet to skin more, make the market prospect of sun care preparations more wide.The anti-sunlight function of sun care preparations mainly comes from the sunscreen in the prescription, so crucial effects has been played in being chosen in of sunscreen in the sun care preparations, the quality of sun care preparations depends on the performance of sunscreen to a great extent.Higher because of sunscreen shared ratio in sun care preparations, its safety and the stability of self will directly have influence on the quality of sun care preparations.
The nano-lipid microgranule coats chemical sunscreen, can significantly reduce the photo-labile of chemical sunscreen, avoided chemical sunscreen to contact simultaneously with the direct of skin, greatly reduce zest to skin, and the particle diameter of solid nano lipid particles is equivalent to the physics ultraviolet light screener, and the chemical uv absorption effect of physical sunscreen effect that self has and chemical sunscreen can be played the effect of Synergistic; In addition, the nano-lipid microgranule that has coated active component because of its particle diameter less than common emulsion, solid-state characteristic is arranged again, on skin, have good closure, and then improved the moisture retention of product; Therefore, the nanometer lipid sun-prevention microparticle of the chemical sunscreen of research coating can promote the extensive use of sunscreen and safety and the effectiveness that improves sunscreen product greatly.The size of nano-lipid microgranule will directly have influence on the closed effect in the application process, and its closure will directly influence its sun-proof property.Subparticle has one to stick effect at the surface of solids, and the particle diameter of microgranule is more little, and it is strong more that it sticks effect.And stick effect is that lipid granule forms the main cause that one deck has closed effect film on skin.The closed effect of nano-lipid carrier has increased the coverage rate on skin, and coverage rate is high more, and sun-proof performance is good more.
