Do essential oil roller blends need to meet IFRA or FDA regulations?

In the US, roller blends are regulated as cosmetics under FDA 21 CFR Part 701, requiring accurate INCI labelling and allergen disclosure. IFRA compliance is an industry standard — not US law — but is required by most EU importers and major retailers. Sensitising compounds like limonene, linalool, and citronellol must stay within IFRA Category 1 (leave-on skin) limits. Vetted manufacturers on AJ Cosmo Labs are familiar with these requirements and incorporate compliance review into their standard process.
