2-Ethylhexyl Salicylate, or octyl salicylate, is an organic compound used as an ingredient in sunscreens and cosmetics to absorb UVB (ultraviolet) rays from the sun. It is an ester formed by the condensation of salicylic acid with 2-ethylhexanol. It is a colorless oily liquid with a slight floral odor. The salicylate portion of the molecule absorbs ultraviolet light, protecting skin from the harmful effects of exposure to sunlight. The ethylhexanol portion is a fatty alcohol, adding emollient and oil-like (water resistant) properties.

Application field Octyl Methoxycinnamate (OMC) is one of the safest and mostwidely used UV B filters. OctylMethoxycinnamate can easily be dispersed into oil phase of anemulsion. It is compatible with most cosmetic materials and can beemulsified either hot or cold. depending upon the emulsifier. Octyl Methoxycinnamate (OMC) offers absorption of UV B radiation from 290 to 320 nm. Octyl Methoxycinnamate (OMC) is ideal for use in sun-care and skin-care products for everyday protection. Octyl Methoxycinnamate (OMC) is suitable for the formulation of sun-protection products.
1. Octocrylene is a UV-B filter that is approved in the USA, Europe, and Japan for use in sun care preparations. 2. Octocrylene is miscible with many cosmetic oils, it can easily be incorporated into the oily phase of an emulsion 3. Octocrylene is hydrophobic and oil-soluble, it is preferred for water-resistant and water-repellant formulations octocrylene is also compatible with all common plasticizers. Function & Application Octocrylene is a UVB sunscreen with strong water-resistant properties and a rather broad-band absorption range. It exhibits good photostability and is being evaluated by many companies as an effective SPF booster and waterproofing enhancer. This is an expensive ingredient with an approved usage level of 7 to 10 percent in both the United States and the European Union. Although gaining in popularity among formulators, its cost and usage level can limit use. In addition, some studies are indicating it may cause allergic reactions in the skin with a history of photoallergy. Use: Octocrylene is chemically related to cinnamates. It can be used to boost SPF and improve water resistance in a given formulation. Octocrylene is photostable and can improve the photostability of other sunscreens. It is expensive and can present difficulties in the formulation.
Ethylene glycol/MEG is also known as ethylene glycol, 1, 2-ethylenediol, or EG for short. Chemical formula is (CH2OH)2, is the simplest dihydric alcohol. Glycol is colorless, odorless, sweet liquid, low toxicity to animals, glycol can be mutually soluble with water, but in the ether class solubility is small. Used as solvent, antifreeze and synthetic polyester raw materials. The polymer of ethylene glycol, polyethylene glycol (PEG), is a phase transfer catalyst and is also used in cell fusion.

Tungsten is a metallic element with the symbol W and atomic number 74, belonging to the VIB family of the sixth cycle in the periodic table. Tungsten is mainly a hexavalent cation in nature, with an iron radius of 0.68-10-10m. Due to the small radius of W6+ions, high electricity price, strong polarization ability, and easy formation of complex anions, tungsten is mainly in the form of complex anions [WO4] 2-, which combine with cations such as Fe2+, Mn2+, Ca2+in the solution to form precipitates of wolframite or scheelite. specification Diamter(mm) Tolerance Max length(mm) sintering,Forging,Spinning Forging and polishing 1.0-10 +0.1 3000 10-20 +0.1 2000 20-50 +0.1 1500 50-70 +0.2 1000 70-90 +0.2 800 >90 Be customized
Introduction Homosalate CAS 118-56-9 is an organic compound used in some sunscreens. It is made by the Fischer-Speier esterification of salicylic acid and 3,3,5-trimethylcyclohexanol, the latter being a hydrogenated derivative of isophorone. Contained in 45% of U.S. sunscreens, it is used as a chemical UV filter. The salicylic acid portion of the molecule absorbs ultraviolet rays with a wavelength from 295 nm to 315 nm, protecting the skin from sun damage. Application The primary application of Homosalate is in sun care products such as sunscreens, lotions, and moisturizers to provide protection against damaging UV rays.
