Fatty Alcohol ｜ Raw Materials for the Chemical and Manufacturing Industries
Key Takeaways
• Fatty Alcohol is a key raw material in the surfactant, chemical, and cosmetics industries
• The carbon chain length (C-chain) directly affects solubility, properties, and applications
• Each type of Fatty Alcohol is suitable for different industries and functions
• Choosing the appropriate type helps improve formulation performance, reduce costs, and maintain stable production quality
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
Fatty Alcohol refers to long-chain alcohols derived from natural fatty acids such as palm and coconut. They are widely used in the chemical, food, cosmetic, and cleaning product industries due to their high stability and safety. In addition, their properties can be adjusted according to the length of the carbon chain.
In production lines, many factories select Fatty Alcohol based only on the chemical name. This can lead to unstable formulations, inconsistent viscosity, or uneven product performance. The main cause is usually the selection of a Fatty Alcohol type that does not match the actual functional requirements of the formulation.
Fatty Alcohols are alcohols with long carbon chains (C8–C22). The longer the carbon chain, the greater the hardness, thickness, and coating properties. Therefore, the final product performance depends directly on the type of Fatty Alcohol selected.
🔷 Octyl Alcohol (C8) | CAS No. 111-87-5
Has a short carbon chain and high volatility. It helps improve substance dispersion and is used as a solvent, coating additive, and fragrance ingredient.
🔷 Lauryl Alcohol (C12) | CAS No. 112-58-3
Provides a balance between solubility and stability. It is a major raw material for surfactants, offering good foaming and high cleansing performance.
🔷 Myristyl Alcohol (C14) | CAS No. 112-72-1
Helps increase thickness and softness. It provides higher stability than C12 and is commonly used in cosmetics and emulsions.
🔷 Cetyl Alcohol (C16) | CAS No. 36653-82-4
A solid alcohol that provides structure and stability. It acts as a thickening agent and co-emulsifier, helping reduce formulation phase separation.
🔷 Stearyl Alcohol (C18) | CAS No. 112-92-5
Provides high hardness and stability while enhancing coating properties. Suitable for formulations requiring strong structural stability.
🔷 Oleyl Alcohol (C18:1) | CAS No. 143-28-2
Contains a double bond that provides flexibility and prevents easy solidification. It helps improve smoothness and absorption.
🔷 Behenyl Alcohol (C22) | CAS No. 30303-65-2
Has a very long carbon chain that provides high viscosity and strong coating properties, helping create a premium texture.
When considering Fatty Alcohol based on carbon chain length
C8–C12 → Fluidity | Good dispersion | Cleaning applications
C14–C18 → Balanced | Stable | Cosmetics and emulsions
C18+ → Thick | High coating | Premium and specialized formulations
Understanding the properties of Fatty Alcohol based on carbon chain length is the key to designing stable chemical formulations and serves as the foundation for selecting other bio-based raw materials suitable for industrial applications.
Summary
Each type of Fatty Alcohol has its own specific role. Selecting the appropriate type improves formulation performance, reduces production process issues, and increases product value. For more details, it is recommended to contact the sales team or review the product documentation.

❓ FAQ
Q: How are Fatty Alcohols different from common alcohols?
A: Fatty Alcohols have long carbon chains, low volatility, and are mainly used for structural and coating functions.
Q: Which C-chain is commonly used in cosmetic formulations?
A: Generally C14–C18 are preferred because they provide stability and a pleasant texture.
