Sodium Cocoyl Isethionate is a natural ingredient that is derived from coconuts, specifically coconut oil.
The process includes mixing a natural sulfonic acid called isethionic acid with the fatty acids that naturally occur in coconut oil.
The mixture is then heated to remove extra water as well as distilled to remove any unnecessary fatty acids.

This powerful ingredient is common in many soaps and cleansers as it effectively washes away dirt and oil without leading to dryness or irritation.
Sodium Cocoyl Isethionate is a sodium salt ester, or a fatty acid derived from coconut oil.
Sodium Cocoyl Isethionate is used in cosmetics and personal care products as a surfactant and is often seen in hair care products like shampoos because of its ability to help water to mix with oil and dirt, allowing them to be more easily rinsed away.
Sodium Cocoyl Isethionate is also seen as an ingredient in a variety of soaps and cleansing products.
As a surfactant, Sodium Cocoyl Isethionate creates a wet feeling, it solubilizes oils and reduces surface tension, and can aid in foaming as well.
Sodium Cocoyl Isethionate is a mild soap-free cleansing agent known for its ability to mitigate disruption of skin's barrier.
Sodium Cocoyl Isethionate is derived from coconut and is regarded as compatible with sensitive skin.
Sodium Cocoyl Isethionate's an anionic surfactant, meaning a cleansing agent with a negative instead of a positive charge.
Sodium Cocoyl Isethionate is a naturally-derived ingredient that comes from the fatty acids that are present in isethionic acid and coconut oil.
These fatty acids are reacted with sodium isethionate and the mixture is heated to remove any water left behind.
Further, the mixture is distilled to remove excess fatty acids.
In its raw form, Sodium Cocoyl Isethionate appears as a fine white powder.
Sodium Cocoyl Isethionate is a mild, high foaming anionic surfactant with high purity made from coconut fatty acids.
Minimum 85% active matter.
Free fatty acid 14% maximum.
Excellent foam density and foam stability.
Has very good lime soap dispersion and surface activity.
Leaves no soap scum as it is very hard water tolerant.
Compatible with soaps and anionic, non-ionic, and amphoteric surfactant.
Excellent lathering; exceptionally mild, provides soft skin after-feel.
Can be used in clear / pearlescent gels.
Sodium cocoyl isethionate is a surfactant that is used in pharmaceutical preparations for skin care.
Sodium Cocoyl Isethionate has good stability and activity index, and can easily be solubilized in water and ethanol.
Sodium cocoyl isethionate has been shown to have antioxidant properties, which may be due to its ability to scavenge free radicals.
Sodium Cocoyl Isethionate also has moisturizing properties, which may be due to the presence of glycerin and fatty esters.
Sodium cocoyl isethionate can be found in fruit extracts, such as mangoes and papaya.
Sodium cocoyloxyethyl sulfonate is an anionic surfactant based on natural coconut oleic acid. Sodium cocoyloxyethyl sulfonate is a mild, high foam personal wash product.

Sodium cocoyl isethionate is the Sodium salt of the coconut fatty acid ester of Sisethionic acid which functions as a surfactant-cleansing agent.
Sodium cocoyl isethionate is in the form of a fine white powder that consists of active ingredient plus minor impurities and has a mild odor.
Sodium Cocoyl lsethionate is stable at a pH of 6-8 and hydrolyzes outside of this pH range.
Uses
Sodium Cocoyl Isethionate is an ingredient derived from coconut oil.
In cosmetics and personal care products, Sodium Cocoyl Isethionate is used primarily in the preparation of bath soaps and cleansing products.
Sodium Cocoyl Isethionate is also used in the formulation of shampoos, tonics, dressings, other hair grooming aids and skin cleansing preparations.
Sodium cocoyl isethionate is used as a surfactant-cleansing agent in cosmetic formulations.
Sodium Cocoyl Isethionate is slightly to practically nontoxic, with an oral LD50 of 24.33 g/kg for rats.
Dermal application of 1.0-36.0% w/w aqueous Sodium Cocoyl lsethionate to rats for 28 days did not produce any significant toxic effects.
Sodium Cocoyl Isethionate is a mild, high-foaming surfactant.
Sodium Cocoyl Isethionate leaves the skin with a soft afterfeel, which is why it is sometimes referred to as "baby foam".
Sodium Cocoyl Isethionate is a good sulfate-free alternative for people who want to avoid commonly known surfactants such as sodium lauryl sulfate (SLS).
Sodium cocoyl isethionate is a popular surfactant used in personal care products, particularly those marketed as gentle or mild.
Sodium Cocoyl Isethionate's widely used in bar soaps, liquid soaps, shampoo bars, body washes, facial cleansers and bath bombs.
1. Sodium Cocoyl Isethionate's mildness and high efficiency, it acts as a self-emulsifier in facial cleanser, which has low irritation, fine and rich foam, and the skin is soft, smooth and silky after washing.
2. Sodium Cocoyl Isethionate has low surface tension, excellent effects of wetting, foaming and detergency, and excellent resistance to hard water.
3. Used for fine textile detergents, Sodium Cocoyl Isethionate is also widely used in the production of daily chemical products such as soap, shower gel, facial cleanser, foaming lotion and bath liquid.

Side effects
The CIR has approved the use of Sodium Cocoyl Isethionate in concentrations up to 50% for rinse-off products, and 17% for leave-on products.
Although Sodium Cocoyl Isethionate is considered generally mild, all surfactants can be irritants, and tend to be more irritating at higher concentrations.
Sodium Cocoyl Isethionate has been specifically shown to cause some eye irritation at higher concentrations.
According to the Cosmetics Database, Sodium Cocoyl Isethionate is also linked to organ-system toxicity (the American College of Toxicology reported that one or more animal studies showed broad systemic effects at high doses), although the EWG notes lesser concerns regarding this side effect, and ultimately finds it to be a low hazard ingredient.
Preparation
Sodium Cocoyl lsethionate is preparedvia the following reaction: sodium isethion- ate is reactedwith either the fatty acid mixture from coconut oil or the corresponding chlorides to form Sodium Cocoyl lsethionate.
Sodium Cocoyl Isethionate was first prepared by adding 1 mole of ethylene oxide to sodium bisulfite.
Manufacture
Sodium cocoyl isethionate is produced by reacting sodium isethionate with coconut fatty acids followed by neutralization with sodium hydroxide.
The mixture is heated to remove water and distilled to remove excess fatty acid.
Sodium Cocoyl Isethionate is originally made by ethoxylation of sodium sulfites and their derivatives.
