This synthetic polymer is used as a fixative in fragrances to prolong scent longevity. It is found in high-end perfumes and body sprays. The ingredient helps stabilize volatile fragrance components, ensuring the scent profile remains consistent throughout wear. Its ability to extend fragrance performance makes it valuable in modern perfumery.
Safety Profile
GENERALLY SAFEWhat Does Poly(oxy-1,2-ethanediyl), .alpha.-[3,5-dimethyl-1-(2-methylpropyl)hexyl]-.omega.-hydroxy- Smell Like?
This ingredient is odorless but acts as a fixative, enhancing the longevity of other fragrance components. It works by slowing the evaporation of volatile top and heart notes, allowing the scent to unfold gradually. Its presence is felt through the extended duration of the fragrance rather than any distinct aroma.
