What is Cocoyl Hydrolyzed Collagen CAS 68188-38-5?

It is a protein-based cosmetic ingredient whose CAS number corresponds to Sodium Cocoyl Hydrolyzed Collagen, made from coconut fatty acid derivatives and hydrolyzed collagen. It functions as a mild cleansing surfactant and as a skin- and hair-conditioning agent.

Why is Cocoyl Hydrolyzed Collagen described as a mild co-surfactant?

It is used in combination with anionic, nonionic, and amphoteric surfactants to reduce the irritation potential of the cleansing system while helping preserve foam quality. This makes it useful in facial cleansers, body washes, baby care products, and mild shampoos.

In what commercial form is Cocoyl Hydrolyzed Collagen usually supplied?

It is normally supplied as a water-soluble liquid with a clear to amber appearance and a mild protein-type odor. A common commercial active content is around 30%, but the exact solids and pH should be confirmed for the selected grade.

What pH range is suitable for formulating with Cocoyl Hydrolyzed Collagen?

Formulation references commonly place its optimal stability in the mildly acidic range around pH 5.0-6.5, while commercial solution pH may be reported near 5.5-7.5 depending on concentration and grade. Match the final formula pH to the supplier recommendation and the other surfactants in the system.

How does Sodium Cocoyl Hydrolyzed Collagen differ from other cocoyl hydrolyzed collagen salts?

The sodium salt has CAS 68188-38-5. Potassium Cocoyl Hydrolyzed Collagen is CAS 68920-65-0, and TEA-Cocoyl Hydrolyzed Collagen is CAS 68952-16-9. They share a protein/fatty-acid condensate structure but differ in counterion, ionic character, and formulation handling.

Cocoyl Hydrolyzed Collagen CAS 68188-38-5

Cocoyl Hydrolyzed Collagen is a lipoamino acid surfactant formed by the condensation of coconut fatty acids and hydrolyzed collagen. Functioning as a remarkably mild, protein-based co-surfactant, it is widely utilized in the formulation of commercial personal care and cosmetic products. Known for its high affinity with keratin, it effectively reduces the irritancy of primary cleansing agents while imparting skin-conditioning and hair-softening properties. In the B2B supply chain, this ingredient is primarily distributed to manufacturers of gentle cleansing systems, such as baby care formulas, premium facial washes, and damage-repair shampoos. We supply this material predominantly as a stable aqueous solution, supported by standard industrial packaging and essential quality documentation to ensure seamless integration into large-scale manufacturing lines.

Physicochemical Properties

Property	Typical Value
Appearance	Clear to amber-colored liquid
Odor	Characteristic mild protein odor
Active Content	~ 30% (Typical commercial solution)
pH (10% aqueous solution)	5.5 – 7.5
Solubility	Soluble in water
Boiling Point	~ 100°C (as water-based solution)

Typical Applications

Personal Care Formulation: Acts as an ultra-mild co-surfactant in facial cleansers, body washes, and baby care formulations. It significantly mitigates the irritation potential of harsher anionic surfactants when used in combined systems.
Hair Care Products: Utilized in conditioning shampoos and professional hair treatments. Its substantivity to hair keratin helps improve combability, reduce static, and provide a smooth, manageable feel.
Foam Modification: Employed as a foam stabilizer and modifier to produce a rich, dense, and creamy lather in premium liquid cleansing systems.

Packaging

As an aqueous solution, this product is standardly packaged in 200kg plastic drums or 1000kg IBC totes designed for safe liquid chemical transport. The containers are specifically selected to ensure the integrity of the protein-based solution, preventing moisture loss and external contamination. Packaging configurations can be accommodated based on specific bulk order requirements and supply logistics.

Storage

Store in a cool, dry, and well-ventilated environment, strictly away from direct sunlight and prolonged exposure to elevated temperatures, which may degrade the protein content. Containers must be kept tightly sealed when not in active use to prevent microbial contamination and the evaporation of the aqueous base. Protect the product from freezing during transit and warehouse storage to maintain phase stability.
