Diethylaminoethyl Dimethoxycinnamate UV Protective Sunscreen Raw Material-CAS 21245-01-2
Octinoxate (Ethylhexyl Methoxycinnamate), also known as OMC, is a high-purity cosmetic grade UVB filter refined by advanced esterification reaction, methoxy modification and multi-stage rectification purification technology. It is one of the most widely used core functional raw materials in the global high-end sunscreen and personal care industry.
Different from traditional inorganic sunscreen agents with heavy texture, easy to whiten and poor skin affinity, and ordinary organic sunscreen agents with low UV absorption efficiency and poor photostability, Octinoxate has a unique methoxycinnamate molecular structure, which is a typical oil-soluble UVB absorber.
It can efficiently absorb ultraviolet rays in the 290-320nm band, with a peak absorption at 310-315nm, forming a dense protective barrier on the skin surface to effectively resist UVB radiation damage, prevent skin sunburn, redness, peeling and long-term photoaging problems such as fine lines and pigmentation.
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 and stabilizer for other UV filters (such as Avobenzone and Octocrylene), improving the photostability of other sunscreen agents, avoiding their decomposition under sunlight, and extending the effective protection time of sunscreen products.
It has lightweight and delicate texture, excellent spreadability and good skin affinity, can be quickly integrated into various cosmetic formulas, will not cause heavy or sticky feeling on the skin, and will not leave white residue on the skin surface, bringing a refreshing and comfortable use experience.
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 lightweight, high-protection and broad-spectrum sunscreen cosmetic formulas.
Key Benefits
