What restricted ingredients should UK buyers avoid under UK cosmetics rules?

Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

• Under the UK Cosmetics Regulation (derived from EU Regulation (EC) No 1223/2009 post-Brexit), buyers must avoid or limit ingredients such as parabens (e.g., methylparaben, propylparaben), phthalates (e.g., diethyl phthalate), formaldehyde donors, and certain colorants (e.g., CI 77266).
• This is enforced by the UK Office for Product Safety and Standards, requiring products to have a safety assessment (CPSR) and proper labelling.
• As an OEM/ODM factory, we guide brands in formulating skincare with approved ingredients, ensuring compliance through documentation like SDS and PIFs, though final regulatory approval rests with the brand.
• For MOQ guidance, compliant formulations often start at 10,000 units per SKU to offset raw material costs for specialized ingredients.
• Sampling typically takes 4-6 weeks, including stability and patch tests.
• We assist with testing for banned substances and microbial limits, plus provide packaging that meets UK labelling rules (e.g., ingredient lists in English).
• Lead time for production includes 1-2 weeks extra for compliance checks, but we cannot guarantee approval—only support with the process.
