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.

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