Sunscreen refers to cosmetics that add a sunscreen agent that can block or absorb ultraviolet rays to prevent skin from being tanned and sunburned. According to the principle of sun protection, sunscreens can be divided into physical sunscreens and chemical sunscreens.
Sunscreens need to choose products with different SPF or PA values according to specific objects to achieve the purpose of sun protection. Sunscreens work by shielding the skin from UV rays. The main difference between sunscreen lotion and sunscreen lotion lies in the physical properties. The general water content of the cream is about 60%, which looks "thick" and is paste-like; while the lotion, with a water content of more than 70%, looks relatively rare and has fluidity. Lotions are generally lighter than creams because of the higher water content, but formulators can still adjust the "greasy" level of creams using different oily ingredients and thickeners. So, you still need to look at the product itself.
KimaCell cellulose ethers are widely used as thickeners, rheology modifiers, emulsifiers and dispersants in Sunscreen products. KimaCell cellulose ethers have pseudoplastic and shear thinning properties. Sunscreen products can be formulated with KimaCell cellulose ethers to not only provide thickening benefits to the product, but also improve solution stability.
