2,5,5-TRIMETHYL-2-PHENYL-1,3-DIOXANE

Description

2,5,5-Trimethyl-2-phenyl-1,3-dioxane is a synthetic fragrance ingredient commonly used in skincare and personal care products. This colorless to pale yellow liquid compound belongs to the family of cyclic acetals and is known for its pleasant, sweet, and floral aroma with hints of herbaceous and woody notes.

In skincare formulations, this ingredient primarily functions as a fragrance enhancer, contributing to the overall sensory experience of the product. It has a low molecular weight, allowing for effective diffusion and long-lasting scent retention. The compound is relatively stable in various pH conditions and compatible with a wide range of cosmetic ingredients.

While 2,5,5-trimethyl-2-phenyl-1,3-dioxane is generally considered safe for use in cosmetics, it may cause skin sensitization in some individuals. As with any fragrance ingredient, patch testing is recommended for those with sensitive skin or a history of allergic reactions.

Formulators typically incorporate this compound at concentrations ranging from 0.1% to 1% in leave-on products and up to 3% in rinse-off formulations. It is often used in combination with other fragrance components to create complex and appealing scent profiles in skincare products such as lotions, creams, and serums.
