Your Proffesional Sodium Laurate Supplier in China
High-Purity Sodium Laurate (分子式 C12H23NaO2) for Soap, 化妆品, 药品 & 工业应用
Sodium Laurate is the sodium salt of lauric acid, a naturally occurring C12 fatty acid found in coconut oil and palm kernel oil. It is widely used as a surfactant, 乳化剂, foaming agent and cleansing ingredient in soap, detergents, skincare, pharmaceuticals and food-processing applications.
Owing to its excellent cleansing ability, mildness, emulsifying performance and formulation stability, Sodium Laurate remains one of the most reliable functional ingredients in both commercial and industrial production.
As a direct manufacturer in China, KosNature supplies high-purity Sodium Laurate with consistent quality, competitive pricing and full technical documentation (TDS, COA, MSDS) for global customers.
What Is Sodium Laurate?
Sodium Laurate (中国科学院 629-25-4) is formed by neutralizing lauric acid with sodium hydroxide. Chemically, it is classified as:
Anionic surfactant
Medium-chain fatty acid salt (C12)
Soap-forming agent
Mild cleansing ingredient
Because of its molecular structure—long hydrophobic chain with an ionic head—Sodium Laurate provides excellent detergency, 乳化, wettability and foaming stability.
It is recognized for:
consistent performance under alkaline conditions
biodegradability
mild-to-skin cleaning
compatibility with natural & synthetic surfactants
主要特点 & 好处
1. Excellent Surfactant Performance
Strong detergency, foaming and degreasing ability, ideal for soap and detergent bases.
2. Mildness & Skin Compatibility
Gentler than many synthetic surfactants, making it suitable for body soaps, facial cleansers and personal care formulations.
3. High Foaming Stability
Stable lather in both hard and soft water.
4. Natural-Origin Ingredient
Derived from coconut and palm oils; biodegradable and environmentally friendly.
5. Wide Formulation Compatibility
Effective in blends with SLS, SLES, potassium soaps, fatty acid salts and amphoteric surfactants.
6. 高纯度 & Low Impurities
Consistent whiteness, low heavy metals and low free acid content.
Sodium Laurate Applications
1. Soap & Detergent Manufacturing
Sodium Laurate is a core base material in:
bar soaps/laundry soap/syndet bars/household and industrial cleaners
It improving hardness, foaming and cleansing performance.
2. 化妆品 & 个人护理
Due to its mild cleansing and emulsifying properties, Sodium Laurate is widely used in:
shampoos/facial cleansers/bath products/shaving creams/toothpaste
It acts as a stabilizer, 乳化剂, lathering agent and thickener.
3. 食物 & Beverage Processing
Used as an emulsifier and anti-caking agent under food-grade standards.
4. Pharmaceutical Applications
Serves as a lubricant, excipient and emulsifying agent in drug formulations.
5. 工业应用
Used in:
emulsified metal cleaners/deinking agents/textile scouring agents
leather treatment chemicals/surface cleaning formulations

| 财产 | Sodium Laurate | Sodium Lauryl Sulfate (SLS) |
|---|---|---|
| Chemical type | Fatty acid sodium salt (C12) | Synthetic sulfate surfactant |
| Mildness | Milder | More irritating |
| Foaming | Strong, stable | Strong |
| 源 | Coconut / palm oils | Petroleum or lauryl alcohol |
| Biodegradability | High | Moderate |
| Use cases | Soap bars, natural cleansers | Shampoos, detergents |
结论
Sodium Laurate is not the same as SLS.
It is generally milder, more natural-origin, and less irritating.
