Product Overview & Specifications

CAS Number: 9005-00-9
Synonyms: PEG-18 stearyl ether, Steareth-18
Molecular Formula: C18H37(OCH2CH2)nOH (n ≈ 18)

Key Applications & Use Cases

Pharmaceutical Industry

Used as solubilizer in oral/topical formulations (e.g., increases bioavailability of poorly soluble APIs by 30-40%).

Cosmetic Formulations

Primary emulsifier in creams/lotions (O/W systems), improves texture stability under extreme temperatures (-20°C to 50°C).

Industrial Applications

Lubricant additive reducing friction coefficients by 15-20% in metalworking fluids.

Industry Case Studies
