Abstract

The invention discloses sunscreen cream and a preparation method thereof. The sunscreen cream is prepared from the following raw materials in parts by weight: a polydimethylsiloxane PEG-10 / 15 cross-linked polymer, 3-4 parts of polydimethylsiloxane, 2.5-3.5 parts of polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer / decamethylcyclopentasiloxane, 1-2 parts of cetyl PEG / PPG-10 / 1 polydimethylsiloxane, 8-10 parts of decamethylcyclopentasiloxane, 4-6 parts of diphenylsiloxy phenyl trimethicone, 2-4 parts of SunCat MTA, 2-4 parts of titanium dioxide, 0.5-1.5 parts of shark glycol, 0.3-0.7 part of phenoxyethanol and 68-73 parts of water. SunCat MTA is matched with titanium dioxide, so that a higher SPF value can be achieved with fewer sunscreen ingredients and lower concentrations, the addition amount of the traditional sunscreen agent is reduced, and the processing cost is reduced; shark glycol is used for inhibiting skin inflammation caused by ultraviolet light, the chemical sunscreen agent is wrapped in a double-layer phospholipid film for shark glycol, and the skin feeling of the sunscreen cream is greatly improved.

Description

technical field [0001] The invention relates to skin care and sunscreen, in particular to a sunscreen and a preparation method thereof. Background technique [0002] Ultraviolet rays in the sun are the first killer of the skin. Ultraviolet rays can not only tan the skin, but also sunburn the skin, accelerate skin aging, and produce wrinkles. People, especially women, have taken sun protection as an important prerequisite for skin care. Today's sunscreen products come in a variety of varieties, with different SPF values, and with different skin feel. Many of these sunscreens or lotions contain chemical ingredients that are very easy to irritate the skin and cause a tingling sensation after sweating, and it is easy to cause skin sensitivity, redness, itching or tingling when removing makeup. [0003] Therefore, the "sunscreen containing liposome components of pearl hydrolyzed liquid" provided by Chinese patent CN101278894B uses liposomes to wrap pearl aqueous solution to redu...
