Octisalate (Ethylhexyl Salicylate) UVB Protective Sunscreen Raw Material-CAS 118-60-5
Octisalate (Ethylhexyl Salicylate) is a high-purity cosmetic grade UVB filter refined by advanced esterification reaction and multi-stage purification technology, which is a core functional raw material widely used in modern high-end sunscreen and personal care industries.
Different from traditional inorganic sunscreen agents with heavy texture and easy to whiten, and ordinary organic sunscreen agents with poor stability and strong irritation, Octisalate has a unique salicylate ester molecular structure, which is a typical oil-soluble UVB absorber, capable of effectively absorbing ultraviolet rays in the 280-320nm band, with a peak absorption at 307-310nm, forming a protective barrier on the skin surface to prevent skin damage caused by UVB radiation, such as sunburn, redness, dryness and long-term skin aging. As a multi-functional sunscreen raw material integrating UV protection, formula stabilization and texture optimization, it not only has excellent UVB absorption capacity, but also can act as a solvent for other UV filters (such as Avobenzone), improving the stability of other sunscreen agents and avoiding their decomposition under sunlight.
It has silky and delicate texture, excellent spreadability and good skin affinity, can be quickly integrated into the cosmetic formula, does not cause a heavy or sticky feeling on the skin, and will not leave a white residue on the skin surface. The product has excellent chemical stability and photostability, can be perfectly compatible with various cosmetic raw materials such as vegetable oils, emulsifiers, silicones, functional active substances and cosmetic pigments, no precipitation or delamination, no oxidation, discoloration or peculiar smell during long-term storage and high-temperature processing, mild and non-irritating, non-sensitizing, non-comedogenic, no harmful impurities, suitable for sensitive skin, oily acne-prone skin, dry skin and infant fragile skin, and is the core raw material for creating mild, high-protection and broad-spectrum sunscreen cosmetic formulas.
