Proextend® CHL is INNO’s Chlorphenesin preservative for cosmetic and personal care formulations. It is supplied as off-white to white crystals or crystalline powder and is recommended at 0.1 to 0.3%. Lotions, creams, face masks, gels, sprays, color cosmetics and shampoos are all listed application areas for this grade.
The product has broad-spectrum activity against bacteria and fungi. Preservation performance must still be confirmed in the complete formula because surfactants, emulsifiers, botanical extracts, packaging and manufacturing conditions can change the result. Compatibility testing and a finished-product challenge test are required before launch.
Recommended applications
In lotions and creams, Proextend® CHL forms part of the preservation system for the water-containing emulsion. It is also suited to face masks, gels and sprays, giving formulators one Chlorphenesin grade across several skin-care formats.
For water-containing color cosmetics and shampoos, Proextend® CHL supports microbial control without changing the intended product category.
Formulation points
Chlorphenesin is slightly soluble in water. The incorporation process therefore needs to achieve complete and uniform dissolution under the intended batch conditions. Check the finished product again after cooling and during stability testing, especially when clarity or a smooth appearance matters.
Formula composition can change preservation performance. Evaluate Proextend® CHL together with the other preservative ingredients, chelating agents, surfactants and extracts present in the final product. Record the exact formula version used for the challenge test so the result is not applied to a later reformulation without review.

Frequently asked questions
Is cosmetic Chlorphenesin the same as chlorphenesin carbamate?
No. Proextend® CHL is Chlorphenesin with CAS number 104-29-0 and is supplied as a cosmetic preservative. Chlorphenesin carbamate is a different chemical substance. Supplier approval and formula records should use the full INCI name and CAS number to prevent confusion.
Can Proextend® CHL be used as the only preservative?
The raw-material specification cannot answer that question for every formula. Water activity, product format, other ingredients, manufacturing hygiene and use conditions all affect preservation. Confirm the complete system with a challenge test on the final formula.
Is this grade suitable for both leave-on and rinse-off cosmetics?
Yes. The recommended applications include leave-on formats such as lotions, creams, masks, gels, sprays and color cosmetics, as well as rinse-off shampoo. The use level and preservation system must be set for the individual formula and its destination market.
What should a buyer compare when qualifying Chlorphenesin suppliers?
Match the INCI name, CAS number, appearance, color, odor, assay method and acceptance limit across the specification and COA. Packaging, shelf life and document revision should also be aligned before the first commercial order.
Why source Chlorphenesin from INNO?
INNO keeps supplier qualification practical: clear product identification, current technical and safety documents, and direct discussion of the target formula. Send us your product format, destination market, planned use level and current preservative system. We will provide the available Proextend® CHL TDS, SDS and COA and help define the next formulation-evaluation step.
