Quick answer
The hydrophobic chains of fatty alcohols such as cetyl or stearyl alcohol and betaine surfactants like cocamidopropyl betaine come from plant oils or possibly animal fatty acids, so the INCI name is not enough. Reviewers ask suppliers for a fatty-chain origin statement, process route, a grade-specific halal certificate, and preservatives or solvents in blends. Aids used in CAPB production need a complete origin chain too.
Detailed explanation
Origin judgment points
- Fatty alcohols: natural-oil and petrochemical routes coexist; the natural route splits plant or animal
- Betaines: fatty acid condensed with an amine, so feedstock oil decides origin
- Blended surfactants: preservatives, thickeners and solvents are often missed
Surfactant Origin Document Checklist
- Chain-feedstock origin statement and oil proof
- Process route, amidation and quaternization, and aids
- Halal certificate covering the grade
- Shared-line and cleaning information
Cosmetic Surfactant Alternatives
Clearly plant-derived coconut or palm-kernel surfactants, alkyl polyglucosides and amino-acid surfactants work as substitutes; run foam, skin-feel and stability tests after switching.
Sourcing reminder
The same INCI name may hide different supplier origins; purchase by grade so chemistry-name receiving does not mix batches of different origin.
