Stearyl Alcohol (CAS 112-92-5) is a C18 saturated fatty alcohol with the formula CH₃(CH₂)₁₆CH₂OH (MW 270.49), also known as 1-octadecanol. It is a white, waxy solid used as an emollient, thickener, emulsion stabilizer, and co-emulsifier in pharmaceutical creams, cosmetic formulations, and personal care products. Stearyl Alcohol has a higher melting point and harder consistency than cetyl alcohol (C16).
TCS Industries Limited, a Hong Kong-based trading and sourcing company, supplies Stearyl Alcohol in pharmaceutical (USP-NF/Ph.Eur.) and cosmetic grades for global procurement programs.
> Applications
Thickener and emulsion stabilizer in pharmaceutical topical formulations
Stearyl alcohol contributes to the consistency, viscosity, and stability of oil-in-water and water-in-oil cream and ointment bases. It is a component of pharmaceutical cream formulations specified in USP and BP. The higher melting point (56–60 °C) compared to cetyl alcohol (45–50 °C) provides firmer texture at ambient temperature. Mohsin et al. (J Pharm Innov, 2016, 11:105–118) evaluated the impact of C16/C18 fatty alcohol ratio on cream microstructure and rheological properties.
Cosmetic emollient and opacifier
Stearyl alcohol provides emollient, conditioning, and opacifying properties in body creams, hair conditioners, and stick formulations (deodorants, lip balms). It is used at 1–10% in emulsion formulations. The waxy character provides structure to anhydrous products. Cosmetic-grade material requires controlled colour (white) and low odor.

TCS Industries Limited supports development, qualification and commercial purchasing discussions for Stearyl Alcohol –- Emollient & Thickener for Creams and Lotions with buyers in South America, Europe, the United Kingdom, Australia, New Zealand, Mexico and Canada.
- Evaluation and commercial quantities: 5 kg samples for formulation trials; 25 kg bags or drums for production. Pharmaceutical (NF/Ph.Eur.) and cosmetic grades available.
- Pallet quantities and production campaigns: repeat supply is coordinated against packaging, lead time, annual demand and destination-market import requirements.
> Quality & Documentation
Key specification parameters include assay (≥95.0% C18 for pure stearyl grade), acid value (≤1.0), iodine value (≤2.0), saponification value (≤2.0), hydroxyl value (200–220), melting range (56–60 °C), colour (white), odor (faint characteristic), and heavy metals. Pharmaceutical grade must meet USP-NF or Ph.Eur. (Alcohol stearylicus) monograph. COA and MSDS are standard.
> Packaging
Stearyl Alcohol is supplied as white waxy pastilles or flakes. Standard packaging includes 25 kg multiply paper bags with PE liner or fibre drums. Store at controlled room temperature (15–25 °C). Shelf life is typically 36 months. Labels and documents are checked before dispatch.
> Pricing & MOQ
Pricing is quoted by specification, packaging and destination. Common commercial discussions use 25 kg bag/drum formats, pallet quantities and production-campaign planning; smaller samples may be reviewed for qualified formulation teams.
> Regulatory & Compounding Context
Stearyl Alcohol is monographed in USP-NF, BP and Ph.Eur. (Alcohol stearylicus). Listed in the FDA IID. INCI-listed (Stearyl Alcohol). Permitted in cosmetics per EU Regulation 1223/2009 (non-restricted). Kosher and Halal certification available. Not classified as dangerous goods. No special import permits required.

> FAQ
What is the difference between Stearyl Alcohol and Cetyl Alcohol?
Stearyl Alcohol (C18, CAS 112-92-5, m.p. 56–60 °C) and Cetyl Alcohol (C16, CAS 36653-82-4, m.p. 45–50 °C) are different chain-length fatty alcohols. Stearyl provides harder consistency; cetyl provides softer texture. They are often used together as cetostearyl alcohol. Specify the pure grade or mixture required.
What documents are available for Stearyl Alcohol –- Emollient & Thickener for Creams and Lotions orders?
COA and MSDS are standard for commercial discussions. COO, packing list, invoice and other import-support documents can be arranged according to order scope.
Can TCS Industries Limited support Stearyl Alcohol –- Emollient & Thickener for Creams and Lotions supply to South America?
Yes. We support B2B buyers in Argentina, Colombia, Chile, Peru, Ecuador, Uruguay, Bolivia, Brazil, Paraguay, Venezuela, Guyana and Suriname, subject to route and document review.
Do you support Europe, the United Kingdom, Australia, New Zealand, Mexico and Canada?
Yes. These destinations can be reviewed for project supply, import documents, packaging and logistics planning before quotation.
Is Stearyl Alcohol a drying alcohol for skin?
No. Stearyl alcohol is a long-chain fatty alcohol with emollient properties. It does not dry or irritate skin. Short-chain alcohols (ethanol, isopropanol, denatured alcohol) are classified as drying alcohols — they are chemically different from C16–C18 fatty alcohols.
Can Stearyl Alcohol be plant-derived?
Yes. Stearyl alcohol is produced from hydrogenation of stearic acid derived from palm, coconut, or other vegetable oils. Plant-derived material is available for natural and vegan cosmetic formulations. Specify the required origin at inquiry.
Can you arrange samples before commercial purchasing?
Samples or evaluation quantities may be reviewed for qualified buyers after target specification, application and destination-market requirements are clarified.
How is Stearyl Alcohol –- Emollient & Thickener for Creams and Lotions packaged for export?
Packaging is confirmed by quantity and material properties. Typical options include foil bags, HDPE containers, fibre drums, 25 kg bags or palletized export packaging.
Can buyer-defined specifications be reviewed?
Yes. Send the specification, methods, impurity limits and required documents. TCS can review feasibility before confirming quotation and lead time.
What payment terms are normally used?
Standard payment is 100% T/T before dispatch unless a different arrangement has been approved for an established commercial account.
What lead time should buyers expect?
Lead time depends on stock, batch size, document scope and destination. Available stock can move faster; made-to-order or pallet programs require longer planning.
Is Stearyl Alcohol monographed in pharmacopoeias?
Yes. Stearyl Alcohol is monographed in USP-NF and Ph.Eur. (Alcohol stearylicus). The pharmacopoeial monograph specifies minimum C18 content (≥95%), hydroxyl value, iodine value, and impurity limits. Specify the target pharmacopoeia at inquiry.
