ALKEMIST™ SDA 40B (Specially Denatured Alcohol 40B)
High-Purity Cosmetic & Perfumery Grade Denatured Ethanol Solvent
Product Overview
ALKEMIST™ SDA 40B is an ultra-pure, cosmetic- and perfumery-grade Specially Denatured Alcohol designed specifically as an optimal carrier solvent for fine fragrances, personal care formulations, and botanical extractions. Processed to exacting chemical and olfactory standards, it features a neutral aroma base that rapidly flashes off without leaving foul denaturant notes, off-putting chemical undertones, or greasy skin residue.
Denatured in strict accordance with standard regulatory formulations using trace tert-butyl alcohol and denatonium benzoate (Bitrex), ALKEMIST™ SDA 40B renders the ethanol unpalatable while preserving complete compatibility with delicate aroma compounds, essential oils, and fixatives.
Key Performance Features
- Olfactory Neutrality: Free from foul, fuel-like denaturants (such as methanol or pyridine); preserves the subtle top notes of bespoke perfumes.
- Superior Solvency: Effortlessly dissolves hydrophobic fragrance oils, essential oils, absolutes, cosmetic esters, and UV stabilizers without cloudiness or phase separation.
- Clean Evaporation Profile: Fast-drying, non-sticky flash evaporation that imparts a refreshed, smooth sensory finish on skin and hair.
- Consistent Purity: Low moisture and minimal non-volatile matter deliver exceptional batch-to-batch stability.
- Regulatory Compliance: Standard denatured formula exempt from beverage alcohol excise burdens, suitable for international cosmetic supply chains.

Formulation & Blending Guidelines
For perfume composition, slowly introduce concentrated fragrance compounds into ALKEMIST™ SDA 40B under moderate mechanical agitation. For optimal aromatic development and harmony, allow a maturation/maceration period (typically 2 to 4 weeks at ambient temperatures away from direct sunlight) followed by chilling and fine filtration (e.g., 0.22 – 1.0 micron) to remove any precipitated waxes or insoluble heavy terpenes.
