What is Octyldodecanol CAS 5333-42-6 2-Octyl-1-dodecanol?
Chemical labeling
Molecular formula: C₂₀H₄₂O
Molecular weight: 298.55 g/mol
Alternative names: Isocitanol, Gelbert alcohol, octyllauryl alcohol, 2-octyl-1-dodecanol
Appearance: Colorless to light yellow transparent oily liquid, almost odorless.
It is recommended to select the purity based on the application scenario: for cosmetics/pharmaceuticals, it should be ≥99% (to reduce impurity irritation), and for industrial lubricants, 90-95% can be chosen (to optimize costs). Strictly follow safe operations to avoid decomposition caused by high-temperature environments
Octyldodecanol CAS 5333-42-6 2-Octyl-1-dodecanol Use
Cosmetics and personal care
Emulsifiers & emollients: Used in creams and lotions to improve skin feel and stretch, and reduce irritation.
Transdermal enhancers: Enhance the transdermal absorption efficiency of drugs (such as naproxen).
Industrial materials
Lubricating oil additive: Synthetic tris (2-octyl dodecyl) cyclopentane, with excellent anti-wear property and low pour point (-57℃), suitable for aviation and automotive engine oil.
Printing and textile auxiliaries: Improve ink wettability, fiber softness and antistatic property.
Organic synthesis intermediate
It is used for the preparation of surfactants, plasticizers (such as sebacate derivatives) and pharmaceutical raw materials.
Octyldodecanol CAS 5333-42-6 2-Octyl-1-dodecanol safety
Health risk
Toxicity: Low toxicity (oral LD₅₀ >5 g/kg in rats), but contact with skin or eyes may cause irritation.
Environmental risk: Toxic to aquatic organisms. Leakage must be prevented.
Protection and Storage
Operation protection: Wear solvent-resistant gloves and goggles, and ensure good ventilation.
Storage conditions: Keep sealed, away from light, in a cool and dry place (<30°C), away from oxidants and acids and alkalis.
