Scent profile

Odour profile (FraterWork)

Octinoxate is a virtually odourless, colourless to pale yellow oily liquid — a functional UVB absorber that protects finished fragrances from light-induced degradation without contributing any noticeable scent.

Appearance (FraterWork)

Clear liquid Odour Profile: Octinoxate is a virtually odourless, colourless to pale yellow oily liquid — a functional UVB absorber that protects finished fragrances from light-induced degradation without contributing any noticeable scent. Uses: Protects perfumes from UVB-induced degradation and yellowing; miscible with fragrance oils, doubles as co-solvent. INCI Name: ETHYLHEXYL METHOXYCINNAMATE IUPAC Name: 2-ethylhexyl (2E)-3-(4-methoxyphenyl)prop-2-enoate

Descriptions

Comment (FraterWork)

Octinoxate is sunscreen for your perfume, not a scent material. This colourless, low-viscosity liquid absorbs UVB radiation (280–320 nm) before it can break down fragrance molecules. At typical use levels, it contributes no detectable odour to a composition. Use Octinoxate wherever UV-sensitive ingredients need shielding — citrus oils, aldehydes, and terpenes are the first casualties of light exposure. It's miscible with most fragrance oils and doubles as a co-solvent, dissolving other oil-soluble additives with ease. Simply stir it into your oil phase. One critical caveat: Octinoxate and Avobenzone destabilise each other under UV light unless a photostabiliser is also present. Add Oxynex ST [https://fraterworks.com/products/oxynex-st] at just 0.5% to quench this reaction and protect both filters. For UVB-only protection, pair Octinoxate with 2-Ethylhexyl Salicylate [https://fraterworks.com/products/2-ethylhexyl-salicylate] instead. OCTINOXATE VS AVOBENZONE Octinoxate and Avobenzone protect against different portions of the UV spectrum. Octinoxate absorbs UVB (280–320 nm) — the shorter-wavelength radiation that degrades terpenes, aldehydes, and other volatile components. Avobenzone absorbs UVA (320–400 nm) — the longer-wavelength light responsible for yellowing liquids and breaking down vanillin. Octinoxate is a pourable liquid that incorporates instantly; Avobenzone is a crystalline powder requiring heat (80–85°C) and a co-solvent to dissolve. Octinoxate itself can dissolve up to 26% Avobenzone by weight, making it a useful carrier for the powder. However, the two destabilise each other through photocyclisation unless a photostabiliser like Oxynex ST is included as a third ingredient. With Oxynex ST present (just 0.5% of the finished formula), the combination provides excellent broad-spectrum UV protection for your fragrances. aromachem Best Seller NEW
