What Is Poly(oxy-1,2-ethanediyl), .alpha.-(isooctylphenyl)-.omega.-hydroxy-?
This synthetic polymer is primarily used in industrial applications rather than consumer fragrances. It’s found in some specialty surfactants and emulsifiers. While not a traditional fragrance ingredient, it may appear in functional fragrance formulations where emulsification properties are required alongside scent delivery.
Safety Profile
PROFESSIONAL USEWhat Does Poly(oxy-1,2-ethanediyl), .alpha.-(isooctylphenyl)-.omega.-hydroxy- Smell Like?
This material is not characterized by any distinctive odor profile as it’s primarily a functional polymer rather than a fragrance ingredient. In formulations, it would serve as a carrier or emulsifier rather than contributing to the scent profile. The polymer itself is typically odorless and tasteless in pure form.
Chemistry, Properties & Perfumer Guide
The Chemistry
Poly(oxy-1,2-ethanediyl), α-(isooctylphenyl)-ω-hydroxy- is a synthetic nonionic surfactant polymer. It belongs to the class of alkylphenol ethoxylates, formed through the polymerization of ethylene oxide with isooctylphenol. The material exhibits surfactant properties due to its amphiphilic structure, with a hydrophobic alkylphenyl group and hydrophilic polyoxyethylene chain. Production involves controlled ethoxylation reactions under alkaline conditions.
