What is Sodium Methyl Lauroyl Taurate?

Sodium Methyl Lauroyl Taurate (INCI: Sodium Methyl Lauroyl Taurate; CAS 27303-29-7) is a high-purity, hypoallergenic anionic surfactant in the N-acyl methyl taurate family. It is produced by acylating N-methyl taurine with lauric acid from vegetable sources and is supplied as a fine white powder with 95% active content and very low inorganic salt levels. Because its sulfonate head group remains fully ionized across the pH range, the ingredient delivers consistent detergency and foam performance under demanding conditions, including hard water. Its skin-compatible structure lifts sebum, dirt and sunscreen while protecting the stratum corneum, leaving the skin clean without dryness or tightness. These properties make it a preferred primary surfactant for premium facial cleansers and high-quality shampoos.

Key Benefits

• Consistent detergency: cleansing power equal to or greater than AES/SLES, with reliable performance batch after batch and across formulation conditions.
• Rich, fine, creamy foam: builds dense, long-lasting lather with a luxurious feel — the classic base for high-end amino-acid cleansing creams and “crystal paste” textures.
• Mild and low-irritation: significantly lower irritation potential than conventional sulfates; it is poorly absorbed by the skin and helps protect the skin barrier.
• Hard-water and pH stable: the sulfonate group stays fully ionized at any pH, maintaining foam and detergency in hard water and challenging systems.
• Easy rinsing, comfortable after-feel: rinses cleanly without residue and avoids the dry, tight sensation left by harsher surfactants.
• EO-free and versatile: suitable for EO-free, sulfate-free and premium free-from formulations, with excellent compatibility with other surfactants and conditioners.

Applications

• Premium facial care: foaming face washes, cleansing creams, facial tubes, amino-acid cleansers and soap-based combination products, where it creates dense, luxurious textures.
• Hair care: mild, cream-type and anti-dandruff shampoos, EO-free shampoos, co-washes and conditioners, supporting rich foam and soft, manageable hair.
• Body care: shower creams, body washes, foam baths, hand washes and syndet cleansing bars with a luxurious lather.
• Baby and sensitive care: gentle infant washes and products for reactive skin, thanks to its low-irritation profile.
• Oral care and other formats: toothpaste, mouthwash and solid or powder cleansers.

Typical use level: 5–30% in rinse-off products. As a high-activity powder it dissolves readily during production and pairs well with amphoteric co-surfactants and humectants.

FAQ

Q1: What is the difference between this and SLES/AES? A1: It offers equal or superior detergency and foam with significantly lower irritation, and it is EO-free, making it ideal for premium and sensitive-skin cleansers.

Q2: Is the powder form easy to use? A2: Yes. The 95% active white powder dissolves readily in the water phase, and it offers high active content, lower transport cost and flexible dosing compared with liquid surfactants.

Q3: Does it work in hard water? A3: Yes. As a sulfonate-type taurate it remains fully ionized across pH and water hardness, so its foam and cleansing performance stay consistent.
