GB cosmetics labels tighten July 2026; enzacamene ban

From 15 July 2026, the rules for cosmetics in Great Britain start to tighten. The UK Government has made Statutory Instrument 2026/23 on 12 January 2026, laid before Parliament on 15 January 2026, to update the retained Cosmetic Regulation (EC) No 1223/2009. We’ve read the official text on legislation.gov.uk so you don’t have to; here’s the plain‑English guide for you and your students.

A sunscreen ingredient called enzacamene-also written as 3‑(4′‑methylbenzylidene)‑camphor-will be prohibited in cosmetic products. It is being removed from the list of allowed UV filters and added to the list of banned substances. Ministers say there is sufficient scientific evidence of a potential risk to human health, which is why this change is being made.

The law also tightens the trigger for a formaldehyde warning on products that use ‘formaldehyde‑releasing’ preservatives. The threshold falls from 0.05% to 0.001% in the finished product, and the legal note now talks about preservatives that ‘release’ rather than ‘contain’ formaldehyde. In practice, more products will carry a clear warning, and they will do so at much lower levels.

CMR is the safety shorthand you’ll see in the schedule. It means carcinogenic, mutagenic, or toxic to reproduction. Under the chemicals rulebook (Regulation 1272/2008), Category 1B signals strong evidence-usually from animal studies-that harm is expected in humans, while Category 2 flags a suspected risk. The instrument adds a set of Category 1B or 2 substances to the cosmetics ban list.

Here are the dates to remember. Most changes, including the enzacamene ban and the new formaldehyde warning threshold, apply from 15 July 2026 in England, Wales and Scotland. A second block of bans-covering the newly listed CMR substances-kicks in from 15 August 2026.

Grace periods are built in so shelves can be cleared. If a product was first placed on the market before 15 July 2026 and contains enzacamene, it can continue to be made available until 14 January 2027-so long as it was labelled under the pre‑July rules. After that date, it must not be supplied.

For the CMR additions that start on 15 August 2026, the sell‑through window runs until 14 February 2027 for items placed on the market before the August start date. That lets retailers move existing stock for six months after the rules take effect, but any new batches must comply from day one.

Two phrases in the law are worth decoding for learners. ‘Placed on the market’ is the first time a product is supplied-think of the moment a brand or importer introduces it into GB commerce. ‘Made available’ covers offering or supplying it later on, such as retail sale. Only items already placed on the market qualify for those sell‑through periods.

What should you look for as a shopper? Expect clearer formaldehyde warnings on more hair, skin and nail products that use these preservatives. If you teach science or PSHE, this is a helpful case study in how hazard labels support informed choices, even at very low concentrations.

If you work in product, retail or labs, the homework starts now. Audit formulas for enzacamene and for substances newly classified as CMR 1B or 2, update labels to meet the 0.001% formaldehyde warning, and plan stock so nothing remains on shelves past January or February 2027. These rules apply in Great Britain (England, Wales and Scotland).

Why now? The Department for Business and Trade cites advice from the Scientific Advisory Group on Chemical Safety of Non‑Food and Non‑Medicinal Consumer Products, pointing to potential health risks from enzacamene and from the previous, higher labelling threshold for formaldehyde‑releasing preservatives. The Government has published an Explanatory Memorandum alongside the regulations on legislation.gov.uk and notes that no full impact assessment was produced.
