What is Cocoyl Glutamic Acid CAS 210357-12-3?

Cocoyl glutamic acid is an amino-acid-based anionic surfactant precursor made from coconut fatty acids and glutamic acid. This CAS identifies the free acid form, which is neutralized during formulation to produce a mild cleansing agent.

Why is this supplied as the free acid rather than a neutralized salt?

The free acid form allows formulators to choose the neutralizing base, such as potassium hydroxide, arginine or triethanolamine. This provides control over pH, clarity, viscosity and final skin feel in the finished product.

What are the main applications?

It is used in mild facial cleansers, sulfate-free shampoos, body washes, baby-care products, liquid soaps and other personal-care formulations where low irritation and gentle cleansing are required.

Why is cocoyl glutamic acid considered a mild surfactant?

It is derived from amino-acid chemistry, is readily biodegradable and typically produces dense but gentle foam. Its mildness makes it suitable for sensitive-skin, baby-care and high-frequency-use products.

How should it be incorporated into a formulation?

Neutralize the free acid with the selected base in water while mixing, then adjust the final pH to the target range. It is usually combined with amphoteric or nonionic co-surfactants, humectants and viscosity modifiers to build the finished cleansing system.

Which grade and packaging are available?

The listing is cosmetic/personal-care grade and is supplied in 1 kg aluminum-foil bags or 25 kg fiber drums with an inner PE liner. Other packaging can follow the customer's requirement.

What specifications should be checked before ordering?

Confirm appearance, acid value, active content, moisture, pH of a reference neutralized solution, heavy metals and microbial limits. Request the current batch analysis, technical data and safety information before purchase.

How should cocoyl glutamic acid be stored?

Store in tightly closed containers in a cool, dry, ventilated area away from moisture, heat and incompatible materials. Use dust-control measures and suitable PPE when handling the powder, and follow the safety information.

Product Description

Cocoyl Glutamic Acid, CAS 210357-12-3, also known as N-cocoyl-L-glutamic acid, is an amino-acid-based anionic surfactant precursor made from coconut fatty acids and glutamic acid.

Synonyms: cocoyl glutamic acid.

CAS: 210357-12-3.

Molecular formula: C₁₇H₃₁NO₅.

It is a white to light-yellow powder or flakes with a slight characteristic odor.

Active content is ≥95–98% (assay).

It is supplied as the free acid form, which is neutralized with NaOH, KOH, arginine or TEA to produce the corresponding cocoyl glutamate salt.

Compared with SLS/SLES, it offers very low irritation, fine creamy foam and excellent skin feel; it is readily biodegradable and derived from renewable raw materials.

It is used in facial cleansers, sulfate-free shampoos, body washes, baby-care products and liquid soaps.

It is used as a primary mild surfactant or co-surfactant to improve foam quality and reduce irritation.

The free acid form allows formulators to choose the neutralizing base and control pH, clarity, viscosity and final skin feel.

It is usually combined with amphoteric or nonionic co-surfactants, humectants and viscosity modifiers.

Its mildness makes it suitable for sensitive-skin, baby-care and high-frequency-use products.

Confirm appearance, acid value, active content, moisture, pH of a reference neutralized solution, heavy metals and microbial limits.

Store in tightly closed containers in a cool, dry, ventilated area away from moisture, heat and incompatible materials.

Confirm packaging with the requested quantity and destination requirements.

Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.
