Sodium Lauroyl Oat Amino Acids-CAS 222400-43-3
Sodium Lauroyl Oat Amino Acids is a premium, plant-derived amino acid surfactant renowned for its exceptional gentleness and skin-friendly properties. Produced by reacting hydrolyzed oat protein amino acids with lauroyl chloride, this mild anionic surfactant combines the nourishing benefits of oat protein with effective cleansing power. Unlike harsh sulfate surfactants that can strip the skin's natural barrier, Sodium Lauroyl Oat Amino Acids cleanses gently while maintaining skin integrity, leaving the skin feeling soft, hydrated, and comfortable rather than tight or dry. Its near-neutral pH matches the skin's natural acid mantle, making it ideal for sensitive, delicate, and baby skin. The surfactant produces rich, creamy, stable foam that feels luxurious on the skin, and it is fully biodegradable, making it an excellent choice for both high-performance and eco-conscious formulations.
Key Benefits
• Ultra-mild cleansing: Very low skin irritation, respects skin barrier, no stripping effect
• Natural plant-derived: Made from oat protein amino acids, renewable and sustainable source
• Skin-friendly pH: Near-neutral pH (6.0–7.5), matches skin's natural acid mantle
• Rich creamy foam: Produces abundant, fine, velvety foam with luxurious sensory experience
• Skin conditioning: Leaves skin soft, smooth, and hydrated, no tightness after washing
• Hair conditioning: Improves hair manageability, reduces static, adds softness and shine
• Hard water resistant: Maintains performance in hard water, no calcium soap formation
• Excellent biodegradability: Easily biodegradable, environmentally friendly and sustainable
• Broad formulation compatibility: Works well with anionic, nonionic, and amphoteric surfactants
• Sensitive skin and baby safe: Extremely gentle, suitable for most delicate skin types

Frequently Asked Questions (FAQ)
Q1: How does Sodium Lauroyl Oat Amino Acids compare to other amino acid surfactants like Sodium Cocoyl Glutamate?
A: Both are mild amino acid surfactants, but oat-derived versions tend to be even gentler with better skin conditioning benefits from oat protein components. Sodium Lauroyl Oat Amino Acids has a slightly higher pH (closer to neutral) and produces richer, creamier foam. It also offers better hair conditioning properties than glutamate-based surfactants.
Q2: Is this surfactant really mild enough for baby products and sensitive skin?
A: Yes, it is considered one of the gentlest anionic surfactants available. Its near-neutral pH, amino acid structure, and oat-derived components make it extremely skin-friendly. It does not strip the skin's natural lipid barrier like harsher surfactants. It is widely used in premium baby care and sensitive skin formulations globally.
Q3: What is the recommended usage level and how do I add it in formulations?
A: Typical usage ranges from 2%–30% active matter depending on product type. Add directly to the water phase of formulations. It is stable in a pH range of 5.0–8.0 and works best at temperatures below 80°C. It can be used as a primary surfactant or blended with other surfactants for synergistic effects.
Q4: How is the foam quality compared to SLS/SLES? Is it good enough for body washes and shampoos?
A: While the initial foam volume may be slightly lower than SLS, the foam quality is superior—richer, creamier, and more stable with better skin feel. For most cleansing products, it provides more than sufficient foam. Many formulators blend it with other surfactants like CAPB to boost foam while maintaining gentleness.
Q5: What compliance documents can you provide?
A: Batch COA, SDS/GHS safety data sheet, Certificate of Origin, China Cosmetic Ingredient Inventory confirmation (No. 08436), technical data sheet, heavy metal and microbiological test reports, plant-derived/natural origin certification, and biodegradability test data. REACH and FDA documentation available upon request.
Q6: What is the shelf life and are there any special storage requirements?
A: Shelf life is 24 months in original sealed packaging. Store in a cool, dry, well-ventilated area away from direct sunlight. Avoid prolonged exposure to temperatures above 80°C, which can cause degradation. Keep containers tightly sealed to prevent evaporation and contamination. No special handling required beyond standard surfactant precautions.
