Regulatory Note

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.

Documentation Supplied

Certificate of Analysis (CoA) for the batch supplied; Safety Data Sheet (SDS / MSDS) in the current GHS format; INCI and technical specification sheet; allergen, GMO and origin statements on request; vegan, halal and kosher declarations where the supply chain supports them.

Available Pack Sizes

Disclaimer & Caution in Use

For external cosmetic use in professionally formulated products only. This is a concentrated raw material, not a finished product: do not apply it undiluted to skin or hair. Wear suitable gloves and eye protection when handling, weigh in a ventilated area, and keep out of reach of children. Patch test every finished formulation. Not for ingestion unless a food or oral-care grade is specifically supplied and documented as such. Seek medical advice in case of eye contact, ingestion or an adverse reaction. Low-pH material. Confirm the finished-product pH and provide the sun-protection and irritation warnings your market requires.

How to work with it

1 Check the phase before you weigh

The specification's Add at row is the one to read first. Water-phase materials added to a hot oil phase are the most common reason a batch separates.

2 Hold the pH inside the stated range

Measure the finished product, not the premix. Outside the range the activity drops away and, for some materials, the degradation route is what causes complaints.

3 Start at the bottom of the use level

Then work up through stability and compatibility testing. Higher is not better, and the destination market's limit may sit below your formulation ceiling.
