About
A reaction product of a trimethylcyclohexenyl pentanone with propargyl alcohol, used as a fragrance and skin-conditioning ingredient with some regulatory complexity.
This ingredient is a reaction product (CAS 68611-23-4) of 1-(2,6,6-trimethyl-2-cyclohexenyl)-3-pentanone (alpha-ionone derivative) with 2-propyn-1-ol (propargyl alcohol). The reaction product is used in cosmetics for its fragrance properties and skin-conditioning effects. EU Cosmetics Regulation 1223/2009 requires fragrance ingredients to comply with IFRA standards and does not specifically restrict this reaction product. However, the ingredient contains an alkyne moiety (propargyl group) which introduces reactivity considerations. The trimethylcyclohexenyl ketone component is related to ionone derivatives used in fragrance. Allergen declaration may be required depending on specific IFRA guidelines. The reaction product's safety profile depends on the extent of reaction and residual starting materials.
