Isoamyl salicylate

CAS: 34377-38-3

Overview

Isoamyl salicylate (CAS 34377-38-3 ), also known as isopentyl salicylate, is a synthetic ester used as a fragrance ingredient in personal care and cosmetic formulations.

It delivers a soft, floral-orchid scent profile that perfumers rely on to add depth and diffusion to finished compositions. In fine fragrance and eau de toilette development, it functions as a mid-note modifier.

This ingredient blends floral, green, and powdery accords. Cosmetic formulators incorporate it into skin creams, lotions, and body washes where a light, lasting scent is required without heavy musk bases.

It also appears in hair care products such as conditioners and styling formulations, where controlled fragrance release on the hair fiber is a formulation objective for the manufacturer.

Soap and detergent manufacturers use it to anchor floral fragrance systems that must perform through rinse-off conditions. Isoamyl salicylate is supplied as a clear to pale yellow liquid.

It is available in fragrance-grade quality, with purity specifications typically at 98% or higher to meet the standards expected by cosmetic and personal care customers.

Packaging options generally range from drum quantities for industrial buyers to smaller lots for fragrance blenders and laboratory-scale development projects in the chemical industry.
