Hexyl salicylate, a common fragrance ingredient, faces new concentration limits in Great Britain from 15 August 2026, when Statutory Instrument 2026/109 comes into force. The legislation caps it from 0.001 percent in toothpaste to 2 percent in adult fragrances, with stricter limits for children under three. Non-compliant stock must be withdrawn by February 2027.
What is changing, and when?
The instrument, made on 4 February 2026 and laid before Parliament on 9 February, amends the UK's retained cosmetics regulation by inserting hexyl salicylate into Annex 3, the restricted-substances list, and adding 17 prohibited substances to Annex 2. As regulatory consultancy Cosmeservice reports, the new limits apply to new products placed on the market from 15 August 2026, while the withdrawal deadline for existing stock falls on 15 February 2027. The direct legal text, including the full category-by-category limits, is published on legislation.gov.uk.
Why restrict a fragrance ingredient?
Hexyl salicylate is classified as a CMR category 2 substance, suspected of damaging fertility or the unborn child, and Cosmeservice reports it also carries a skin-sensitizer classification. Rather than ban it, UK regulators adopted a safety dossier that permits continued use within the new limits, which vary by product type and by whether the product is intended for young children. The move follows a similar European Union restriction, meaning brands reformulating for one market will largely meet the other's rule as well.
What does this mean for shoppers?
For consumers, nothing needs discarding this week: the obligation sits with brands, not buyers, and reformulated versions of familiar scents will simply replace old ones on shelves through 2026 and early 2027. The practical significance is informational, since ingredient lists are where this change is visible. Hexyl salicylate has long appeared near the end of fragrance-heavy formulas, and readers who track allergens will now see it either drop below the limits or disappear as brands reformulate.
For readers outside the UK, the ripple is larger than the map suggests. As Cosmeservice notes, the EU's Regulation (EU) 2026/78 covers similar ground, so global brands reformulating to one market's limits will largely carry the change into the other, meaning ingredient lists in the US and elsewhere will shift too as a side effect. Cross-market shoppers may spot hexyl salicylate thinning out of international formulas well before any US rule addresses it, which is how ingredient restrictions usually reach American shelves: quietly, through supply chains, before headlines.
