What is Sodium Lauroyl Oat Amino Acids?

Sodium Lauroyl Oat Amino Acids (INCI: Sodium Lauroyl Oat Amino Acids; CAS 222400-43-3) is a mild, bio-inspired anionic surfactant in the acyl amino acid family. It is produced by condensing lauric acid, typically sourced from coconut or palm, with the characteristic amino acids of oats, and is supplied as a pale-yellow to clear liquid at 25% active content. Its lipoamino acid structure is highly compatible with the skin, giving it a selective, physiological cleansing action that lifts dirt, excess sebum and sunscreen while respecting the skin barrier. The ingredient is readily biodegradable and plant-derived, making it a natural, responsible choice for formulators developing gentle facial cleansers, body washes, baby care and sensitive-skin products.

Key Benefits

• Exceptionally mild cleansing: minimal delipidation and low irritation potential compared with SLS/SLES and other traditional surfactants; it can reduce the overall irritation of a surfactant blend.
• Abundant, creamy, stable foam: builds a rich, cushiony lather even under difficult conditions such as hard water, low pH and high sebum, with good makeup-removing power.
• Skin-compatible and comfortable: the oat-amino-acid base supports the skin’s natural moisture balance and leaves a soft after-feel rather than tightness.
• Natural source, biodegradable: derived from oat amino acids and vegetable lauric acid; supports natural, sulfate-free and eco-conscious claims.
• Versatile co-surfactant: compatible with anionic, nonionic, amphoteric and cationic systems, and easy to formulate at neutral pH.
• Multi-functional: combines cleansing, skin and hair conditioning and antistatic benefits in a single ingredient.

Applications

• Facial care: gentle gel and cream cleansers, foaming face washes, makeup removers and micellar-style products, including formulations for sensitive and reactive skin.
• Body and baby care: body washes, shower creams, liquid soaps, bubble baths and mild infant shampoos and washes.
• Hair care: gentle shampoos, co-washes, conditioners and children’s hair products, where it reduces irritation and improves softness and combing.
• Specialty lines: sulfate-free and AES-free formulations, natural and “free-from” ranges, and solid or paste cleansers.

Typical use level: 5–30% in rinse-off products and 0.1–0.8% in leave-on products. It pairs especially well with amphoteric surfactants such as cocamidopropyl betaine and with humectants such as glycerin and panthenol to further boost mildness.

FAQ

Q1: Is it suitable for baby and sensitive-skin products? A1: Yes. Its physiological, oat-amino-acid structure provides very gentle cleansing with minimal stripping, which is why it is widely used in infant washes and facial cleansers for sensitive skin.

Q2: Does it foam well despite being mild? A2: Yes. It produces an abundant, creamy, stable lather that rinses off easily, and it continues to foam well under hard water and other demanding conditions.

Q3: Is it a sulfate surfactant? A3: No. It is an acyl amino acid surfactant, so it can replace or reduce SLES/AES in sulfate-free formulations while improving skin feel.

Q4: Can I request samples, COA and SDS? A4: Yes. Contact YLPTO for samples at 25% active content, along with COA, SDS and formulation guidance; our technical team supports you from trial to scale-up
