Appearance Waxy solid/flakes
Acid value ≤ 8 mg KOH/g ≤ 10 mg KOH/g
Water ≤ 1.5% ≤ 2.0%
Color Light yellow
CAS (reference) 1338‑39‑2
Use W/O emulsifier, dispersant
Applications Packaging Storage & Handling
• W/O emulsions, wetting and dispersion in agro formulations (EC, EW, ME).
• Personal care/OTC creams and balms (grade permitting).
• Coatings, metalworking fluids, defoamers.
• 25 kg cartons/pails (solids) • 200 kg drums • 900–1000 kg IBC (liquids).
• Food/cosmetic grades, Kosher/Halal on request.
• Store cool and dry, sealed. Warm solids gently (≤ 60 °C) to liquefy—avoid overheating.
• Protect from moisture/air; rotate stock FIFO to control peroxide value.
HS classification depends on formulation and market (surfactants 3402 / preparations 3824). Buyer must confirm labeling and approvals for the destination use.
