Key Properties & Benefits

• Preservation across a wide pH range
• Contributes to a preservation system that must still be validated by challenge testing on the finished product.

Uses & Applications

Caprylhydroxamic Acid and Glyceryl Caprylate is used in every water-containing format — cleansers, toners, serums, creams, masks and hair care.

Typical applications from the catalogue record: Natural-positioned skincare at neutral pH.

As a formulation essential it is specified by function rather than by claim, and the level is set by the performance the formula needs rather than by a marketing target.

Handling note: Warm gently to a pourable consistency before weighing; do not overheat.

How to Use — Recommended Use Level

General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Technical Specification

Technical Notes

Works at neutral pH where the acid-based naturals fail — but it is sensitive to chelators.

Regulatory Note

Preservatives are permitted only if they appear on the destination market's positive list, and only within the stated maximum and conditions of use. Levels apply to the total from all sources in the formula. Confirm the current entry and support the finished product with challenge testing.

Supplier diligence required: Confirm efficacy by challenge testing; chelator interaction possible.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.

Disclaimer & Caution in Use

For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished cosmetic, and it is not intended for undiluted application to skin, for ingestion, or for any medicinal purpose. Wear gloves and eye protection when handling, avoid raising dust with powders, and keep out of reach of children and pets. Always run a patch test on the finished formulation, and validate stability, compatibility, pH and preservative efficacy before sale. Information supplied is offered in good faith as formulation guidance and does not constitute a safety assessment, a regulatory approval or a medical claim.

Low-pH material. Can cause burns to skin and eyes in concentrated form. Add to water, never water to acid; neutralise carefully and confirm the final pH of the finished product. Products formulated at low pH increase sun sensitivity — a daily sunscreen instruction is expected on the finished pack.
