Sodium Ethyl 2-sulfolaurate CAS 7381‑01‑3

Sodium Ethyl 2-sulfolaurate CAS 7381‑01‑3

Sodium Ethyl 2-sulfolaurate, with CAS number 7381-01-3, can also be called sodium lauroyl isethionate. This is an anionic surfactant (sulfate-free), synthesized from lauric acid (a natural fatty acid derived from coconut or palm) and sodium hydroxyethylsulfate.

Solubility: Excellent solubility in hot water, lower solubility in room temperature water; recommended for high-temperature feeding (about 80℃)
pH (10% aqueous solution): 4.7 – 6.0; suitable formula pH range 5.0 – 7.0
Core functions: Cleansing, foaming, calcium soap dispersion, skin sensation conditioning, anti-static

Спецификация

Применение

– Sodium ethyl 2-sulfolaurate can be used to produce soap / syndet bar (a popular mild soap).
– Suitable for sensitive skin facial cleanser, cream cleanser, body wash, hand sanitizer.
– Sulfate-free shampoo, hair care products for infants and children.
– Foaming agent for toothpaste, makeup remover; a small amount of Sodium ethyl 2-sulfolaurate is used in industrial mild cleaning agents.

✨ Product Features

1. Extremely low irritation, sodium ethyl 2-sulfolaurate is gentle on the skin/ scalp: The protein denaturation is much lower than that of SLS and SLES. It is the preferred choice for sensitive skin and baby/child hair care formulas. It does not damage the skin barrier during washing, and after washing, there is no dryness or tightness.
2. Fine, creamy foam, strong stability in hard water: The foam is fine and creamy, and remains stable even in soft water and hard water conditions; It has excellent calcium soap dispersion ability, and when combined with fatty acids to make synthetic soaps, it does not produce soap scum or floating debris.
3. Excellent compatibility in formulation: Sodium ethyl 2-sulfolaurate can be combined with anions, non-ions, amphoteric surfactants, and most cationic conditioners; When combined with betaine, it can synergistically increase foam, and the formulation has high flexibility.
4. Self-regulating effect: After washing the skin, it becomes soft and smooth; When used in shampoo products, it can reduce hair static electricity, reduce flyaway hair, and improve the smoothness and ease of combing of hair strands.
5. Biodegradable, green raw materials, good environmental attributes; Stable in weakly acidic and weakly alkaline systems; Easily hydrolyzed in strongly acidic and strongly alkaline environments, and the formula needs to avoid extreme pH.
6. Manufacturing advantages: Sodium ethyl 2-sulfolaurate is used as a synthetic soap base for soap bars, improving the printing and shaping of soap bars, and enhancing the appearance and usage feel of the finished product.

Вопросы и ответы

Q: Poor solubility in cold water?
A: Correct. It dissolves well in hot water. Recommended feeding temperature: 75~80℃under stirring.

Q: What pH range is stable?
A: Raw material solid is stable. In finished formulation, keep pH 5.0~7.0. Long-term storage above pH7.5 will cause ester hydrolysis and reduce activity.

Q: What applications?
A: Syndet solid cleansing bar, sensitive skin facial cleanser, body wash, sulfate-free shampoo, baby care, toothpaste foaming agent.

Q: MOQ & sample?
A: Sample available; bulk MOQ: 25kg.

Q: Shelf life?
A: 24 months under sealed cool & dry storage.
