Basic Information
Product Name: Sodium Laurate
CAS Number: 629-25-4
Alias: Sodium dodecanoate, Lauric acid sodium salt
Chemical Full Name: Sodium dodecanoate
Molecular Formula: C12H23NaO2
Molecular Weight: 222.30
EINECS: 211-082-4
Structural Information
- Structure Type: Anionic saturated fatty acid salt
- Structural Features: Long linear alkyl hydrophobic chain + carboxylate hydrophilic head group; good surface active performance, easy to form micelles in water
- Characteristic: Mild low-irritation surfactant, excellent foaming and emulsifying capacity
Physical & Chemical Properties
- Appearance: White crystalline powder or flake solid
- Odor: Faint characteristic fatty odor
- Melting Point: 240–242 °C (decomposes)
- Density (20℃): 1.12 g/cm3
- Solubility: Soluble in hot water, ethanol; slightly soluble in cold water; insoluble in mineral oil, benzene
- Stability: Stable under dry sealed storage; hydrolyzes in acidic environment to release lauric acid; compatible with nonionic surfactants, unstable with strong acid and polyvalent metal ions (forms insoluble laurate precipitates)
Synthesis & Applications
Production Method
Neutralization reaction of lauric acid with sodium hydroxide aqueous solution, concentration, spray drying or flaking to obtain finished product.
Main Applications
- Daily chemical surfactant: Mild foaming raw material for facial cleanser, shampoo, body wash, soap base
- Cosmetic emulsifier: O/W emulsifier for cream, lotion, makeup remover
- Industrial additive: Metal lubricant, plastic heat stabilizer, textile softening agent
- Food auxiliary: Food-grade emulsifier and anti-caking agent
- Laboratory reagent: Raw material for preparation of other laurate derivatives
Safety & Storage Instructions
GHS Hazard Classification
- H315 Causes skin irritation
- H319 Causes serious eye irritation
- H335 May cause respiratory irritation from dust inhalation
Personal Protection
Dust mask, chemical splash goggles, nitrile gloves; ventilated operation to avoid dust inhalation.
Storage Condition
Hermetically sealed plastic lined paper drum, cool dry warehouse ≤30℃; isolate strong acid, avoid moisture absorption and caking.
Transportation
General fine chemical solid powder; waterproof packaging to prevent dampness.
Quality Specifications
- Purity: ≥98.0%
- Loss on Drying: ≤0.5%
- Free lauric acid: ≤1.0%
- pH (1% aqueous solution): 9.0–11.0
