Applications & Typical Uses
Fragrance Applications
Fine fragrances and eaux de toilette
Soaps, shampoos, lotions
Air fresheners and candles
Qualification Before Purchase
Confirm the material identity (CAS 87731-18-8), supplied grade and intended fragrance application.
Request the current TDS, SDS and batch CoA, including the assay method and specification.
No food-use suitability is established by this fragrance profile; confirm any proposed food use in writing for the exact grade and destination market.
Household & Personal Care Products
Fabric softeners
Antiperspirants
Liquid detergents
Soaps and detergents: Confirm compatibility in the actual base; the supplier reference rates pH 11 powder detergent performance as poor.
Cleaning formulations require base-specific evaluation; the supplier reference rates bleach stability as poor.
Formulation Strategy & Pairings
Pairs well with: Linalool, Citronellol, Geraniol, citrus oils, and floral notes.
Role: Provides freshness, diffusion, and top-note lift.
Tips for Formulators:
Follow the supplier’s guidance on oxidation control and storage.
Combine with long-lasting bases (woody or balsamic notes).
Avoid high-pH environments to maintain stability.
Regulatory & Safety Overview
Food-use scope: No food-use suitability is established by this fragrance profile. Obtain written confirmation for the exact supplied grade, proposed application and destination market.
Fragrance use: Check current IFRA Standards and supplier restriction information for the exact material and intended product category.
Allergen information: Request a current supplier declaration and assess the destination market’s finished-product labeling requirements.
Handling and safety: Consult the current SDS and complete an application-specific assessment for the supplied grade and proposed use.
Analytical & Quality Control
Identity Verification: GC-MS retention index and spectrum
Assay: Supplier reference minimum is 65% for the main GC peak; confirm the current specification and batch CoA.
Monitoring: Evaluate oxidation products and pH-dependent stability
Purchasing Checklist
☑ Confirm CAS 87731-18-8, supplied grade and the 65% minimum main-peak reference against the current specification and batch CoA
☑ Confirm stability data and storage conditions
☑ Request the SDS, current allergen declaration and IFRA restriction information where relevant
☑ Conduct pilot trials in target formulations
