Description
Specification:
Sodium Cocoyl Isethionate (SCI) is a mild anionic surfactant,It’s formed by reacting coconut fatty acids (predominantly lauric acid) with sodium isethionate,creating an ester linkage between the fatty acid chain and the sulfonate,bearing isethionate group:
Coconut fatty acid–CO–O–CH₂CH₂–SO₃Na.
SCI Cas 61789-32-0 is typically supplied as a white to off-white waxy solid, powder, flake or noodle form. It’s only slightly soluble in cold water but becomes more soluble/active when combined with other surfactants or when the formulation is warmed,making it well-suited for solid formats.

Application of Sodium Cocoyl Isethionate:
1.Synthetic detergent cleansing bars (main use)
SCI is a flagship ingredient in modern soap-free cleansing bars, which are increasingly used as a gentler alternative to traditional saponified soap bars:
>Facial cleansing bars — Widely used in dermatologist-recommended and sensitive-skin cleansing bars (e.g., products marketed for acne-prone, eczema-prone, or generally sensitive skin) because it cleanses without the high pH and stripping effect of traditional soap.
>Body cleansing bars — Used in premium solid body wash bars as an alternative to traditional soap.
2.For mild, low-irritation cleansers
SCI is prized in personal care formulation specifically because:
It has a near-neutral pH compatible with skin’s natural pH (unlike traditional soap, which is alkaline).
It produces a rich, creamy, dense lather while being significantly gentler than harsher surfactants like sodium lauryl sulfate.
It doesn’t strip the skin’s natural oils as aggressively,making it popular in sulfate-free or gentle as SCI is technically a sulfonate,not a sulfate.
3.Used for solid shampoo bars
Increasingly popular in solid shampoo bar formulations,valued for gentle cleansing of hair and scalp without over-drying.
4.For sensitive skin products
Its gentle profile makes it a common choice for sensitive or compromised skin barriers.
Safety of it:
It is ordinary product,the MSDS of it can be provided.
Practical note on formulation: Sodium Cocoyl Isethionate is harder to work with than liquid surfactants because of its poor cold-water solubility and waxy consistency — it typically requires heating and specific processing techniques (often blended with co-surfactants like cocamidopropyl betaine or sodium lauryl sulfoacetate) to create a smooth, moldable solid cleansing bar. This is part of why it’s more expensive and technically demanding to formulate with compared to traditional soap or simpler surfactants, but the mildness payoff has made it a go-to choice in the gentle/dermatologically-focused skincare segment over the past decade.
