Shampoo and conditioner OEM for Thailand: what matters in a sulfate-free formula and on the label?
OEM sulfate-free hair care for Thailand is governed by the Cosmetics Act B. E. 2558 (2015) and its 2022 amendment. First, verify that surfactants and co-solvents are not on the ASEAN Cosmetic Directive prohibited or restricted lists. Second, a Thai-language label is legally required and must be affixed within 30 days of import. Third, any 'sulfate-free' claim must be substantiated by the absence of SLS or SLES, and preservative systems must pass ISO 11930 / USP <51> challenge tests.
1Pre-market notification pathway
A pre-market notification must be filed electronically with the Thai FDA's Cosmetic Control Group before manufacture or import.
2Statutory label requirements
Thai-language labels must be affixed within 30 days of import, including product name, notification number, ingredients, importer details, and net content.
3Sulfate-free surfactant selection
Sulfate-free systems typically use APG or amino acid surfactants, requiring evaluation of foaming, rinse-out, and preservative challenges, avoiding high-concentration fragrance.
