Lauroyl Glutamic Acid supplier
🌿 Lauroyl Glutamic Acid – Technical Grade Amino Acid-Based Surfactant
Lauroyl Glutamic Acid is an amino acid–derived surfactant obtained through the condensation of lauroyl chloride (C12 fatty acid) and L-glutamic acid. With its amphiphilic molecular structure, it provides excellent surface activity, emulsification, and dispersion properties while maintaining low skin irritation.
It is widely used in cosmetic formulations, personal care products, and mild cleansing systems, especially for sensitive skin, baby care, and premium haircare products. The raw materials are plant-derived, aligning with natural and eco-friendly product trends.

⚙️ Formulation Tips
Lauroyl Glutamic Acid is compatible with a wide range of cosmetic ingredients, including anionic, nonionic, and amphoteric surfactants. Its recommended usage varies depending on the product type, desired mildness, and formulation pH.
1. Facial Cleansing Foam (Mild Formula)
Target pH: 5.0 – 6.0
Recommended Dosage: 2 – 5% (active matter)
Example Formula:
| Ingredient | % w/w | Function |
|---|---|---|
| Lauroyl Glutamic Acid | 4.0 | Mild amino acid surfactant |
| Cocamidopropyl Betaine | 5.0 | Foam booster & mild co-surfactant |
| Glycerin | 3.0 | Humectant |
| Sodium PCA | 1.0 | Moisturizer |
| Preservatives (Phenoxyethanol etc.) | q.s. | Preservation |
| Citric Acid / NaOH | q.s. | pH adjustment |
| Water | to 100 | Solvent |
Formulation Tips:
- Ensure pH is maintained between 5.0 – 6.0 for optimal skin compatibility.
- Combine with amphoteric surfactants for richer foam and reduced irritation.
2. Baby Shampoo
Target pH: 5.5 – 6.5
Recommended Dosage: 1 – 4% (active matter)
Example Formula:
| Ingredient | % w/w | Function |
|---|---|---|

| Disodium Laureth Sulfosuccinate | 4.0 | Ultra-mild primary surfactant |
| PEG-120 Methyl Glucose Dioleate | 1.0 | Viscosity builder |
| Hydrolyzed Wheat Protein | 0.5 | Hair conditioning |
| Preservatives | q.s. | Preservation |
| Water | to 100 | Solvent |
Formulation Tips:
- Avoid strong anionic surfactants to keep the irritation index low.
- Add natural conditioning agents (e.g., hydrolyzed proteins) to improve hair feel.
3. Moisturizing Body Wash
Target pH: 5.5 – 6.0
Recommended Dosage: 3 – 6% (active matter)
Example Formula:
| Ingredient | % w/w | Function |
|---|---|---|
| Lauroyl Glutamic Acid | 5.0 | Mild cleansing base |
| Sodium Cocoyl Isethionate | 6.0 | Creamy foam enhancer |
| Betaine | 3.0 | Skin conditioning |
| Aloe Vera Extract | 1.0 | Soothing agent |
| Fragrance | q.s. | Sensory enhancement |
| Water | to 100 | Solvent |
Formulation Tips:
- Combine with isethionates for a richer, creamier foam texture.
- Maintain mild acidic pH for skin barrier protection.
4. Makeup Remover Cleanser
Target pH: 5.0 – 6.0
Recommended Dosage: 2 – 5% (active matter)
Example Formula:
| Ingredient | % w/w | Function |
|---|---|---|
| Lauroyl Glutamic Acid | 4.0 | Gentle emulsifier & cleanser |
| Caprylyl/Capryl Glucoside | 3.0 | Solubilizer for oils |
| Light Mineral Oil / Ester Oil | 10.0 | Makeup dissolution |
| Glycerin | 2.0 | Moisturizer |
| Preservatives | q.s. | Preservation |
| Water | to 100 | Solvent |
Formulation Tips:
- Pair with mild nonionic surfactants for better oil removal.

5. Solid Cleansing Bar (Syndet)
Recommended Dosage: 5 – 15% (active matter)
Example Formula:
| Ingredient | % w/w | Function |
|---|---|---|
| Lauroyl Glutamic Acid | 8.0 | Mild surfactant base |
| Sodium Cocoyl Isethionate | 30.0 | Primary cleansing agent |
