For a product developer it is important to know what ingredients could face restrictions in the future. This allows the developer to select their ingredients so they are not forced to make changes after the restriction or prohibition becomes official.
The process varies from region to region. Typically, Safety committees issue preliminary opinions. Governments notify the WTO. Advocacy groups publish reports. The ban itself, when it finally arrives, is typically the end of a 3-5 year process that was visible to anyone paying attention.
The list below identifies ten ingredients currently in that warning window — under active scientific review, the subject of new restrictions, or facing regulatory proposals that are gaining momentum across multiple markets. None of these is an alarm; several remain permitted in most markets today. But each represents a formulation risk worth assessing now, while you still have time to find alternatives and build a supply chain around them.

In-Depth: Five Ingredients Worth Immediate Attention
1. Octocrylene — The Next Sunscreen Ingredient Facing a European Exit
Octocrylene is one of the most widely used UV filters in sunscreens, moisturizers, and anti-aging products globally. It absorbs UVB and short UVA radiation effectively, is photostable, and has decades of use behind it. Which is what makes its current regulatory situation notable.
ECHA has issued a proposal to drastically restrict octocrylene's use due to concerns over its potential harmful effects on the environment and the availability of safer alternatives. Under the draft restriction, cosmetic products containing octocrylene at concentrations equal to or greater than 0.001% w/w would no longer be allowed to be placed on the EU market. A two-year transition period would apply after the regulation enters into force. The public consultation closed in March 2026.
That proposed limit — 0.001% — is essentially a functional ban. Octocrylene's UV-filtering efficacy requires concentrations typically between 1% and 10%. A limit of 0.001% means it cannot perform its intended function.
For formulators: if octocrylene is in any of your products targeting the EU market, this is the time to begin evaluating alternatives. The regulatory window between ECHA proposal and enacted ban is typically 2-3 years — which maps directly to a typical reformulation and supply chain timeline.
2. Benzophenone-1 (BP-1) — A Ban Already Confirmed
The EU July 2026 draft regulation introduces new prohibitions for Benzophenone-1 following SCCS opinions, combined with CMR-related amendments. CMR-related prohibitions shall apply from February 1, 2027.
BP-1 (also known as Oxybenzone-1 or Uvinul 400) has been used as a UV filter and UV-absorber in various cosmetic and personal care products. The SCCS assessed Benzophenone-2 and related compounds due to concerns regarding their potential endocrine-disrupting properties, concluding that safety could not be established due to inability to exclude genotoxic potential and limited data on repeated-dose and reproductive toxicity.
This is not a proposal — it is a confirmed prohibition. If you're formulating for the EU or UK and BP-1 appears anywhere in your formula (including as a UV stabilizer protecting fragrance or color), it needs to come out before the February 2027 deadline.
3. Propylparaben and Butylparaben — Tightening, Not Banned
Parabens have been under scrutiny for over two decades since a 2004 study detected them in breast tissue. The science since then has been nuanced — the original alarm was not supported by causal evidence — but regulators have progressively tightened limits, particularly for longer-chain parabens and products used on children.
Propylparaben and butylparaben face stricter limits under EU cosmetics regulation, with a maximum of 0.14% (as acid) each when used individually, contributing to an overall 0.8% paraben cap when combined with other parabens. These stricter thresholds stem from SCCS findings that higher concentrations may pose endocrine risks, especially with prolonged skin exposure. Propylparaben and butylparaben cannot be used in leave-on products for the diaper area of children under 3 years old.
The SCCS has issued preliminary opinions flagging additional safety concerns for Butylparaben in products used by children under 10. The direction of travel is clear: further restrictions on product type and age group are likely in the next revision cycle. Formulators serving the children's personal care market should be treating these parabens as ingredients with a limited runway.
The short-chain variants — methylparaben and ethylparaben — remain on a more stable regulatory footing for now. But given the pattern of progressive restriction, building formulas dependent on any paraben system warrants a longer-term substitution plan.
4. Formaldehyde-Releasing Preservatives — A Tightening Net
Formaldehyde releasers are a class of preservatives — including DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea, and quaternium-15 — that work by slowly releasing small amounts of formaldehyde in a formula to inhibit microbial growth. They are effective, inexpensive, and have been widely used for decades. The regulatory pressure on them is now coming from multiple directions simultaneously.
The UK's 2026 cosmetics amendments include stricter labelling requirements for formaldehyde-releasing preservatives effective July 15, 2026 — the trigger threshold for mandatory warnings drops from 0.05% to 0.001%. This is a dramatic change: at 0.001%, virtually any formula containing a formaldehyde releaser will now require an on-pack warning in the UK.
Japan's Ministry of Health, Labour and Welfare has banned formaldehyde-releasing preservatives in mascaras and eye cosmetics, targeting DMDM hydantoin and imidazolidinyl urea specifically, citing eye irritation and cancer risks.
At the US state level, Washington's HB 1047 (effective 2025) bans formaldehyde and formaldehyde-releasing agents in cosmetics. Vermont and Oregon follow in 2026 and 2027 respectively.
The pattern across all four regions is the same: formaldehyde releasers are being progressively restricted or eliminated. For new formulations, designing them out entirely is the lower-risk path.
5. Galaxolide (HHCB) — The Fragrance Ingredient Watching Its Clock
Galaxolide is a synthetic musk — one of the most widely used fragrance ingredients in personal care, home care, and fine fragrance globally. It gives products a clean, musky, long-lasting scent character and has excellent skin substantivity. It is also, by most environmental measures, a persistent bioaccumulative substance.
Galaxolide is part of the 81 new fragrance allergens requiring labelling in the EU and Canada. Any future CMR classification would therefore add further concern on top of the environmental issues already associated with this ingredient. There might be a window of opportunity for Galaxolide if the long-awaited Cosmetics Regulation recast removes the food safety criteria for SCCS review — however, even if Galaxolide undergoes an SCCS review, it does not guarantee that the ingredient would remain allowed at current levels in the EU.
For fragrance formulators and perfumers, Galaxolide sits in an uncomfortable middle ground: widely used, technically not yet restricted, but with a combination of environmental persistence, allergen labelling requirements, and potential CMR classification making it a high-risk long-term ingredient. The fragrance industry has been quietly building alternative musk systems for years. If Galaxolide is a significant contributor to your fragrance profile, understanding what would replace it is worth doing now.
A Note on Methodology
This list was compiled from official SCCS opinions, EU Regulation (EU) 2026/909, ECHA restriction proposals, UK statutory instruments, and regulatory notifications to the WTO published through mid-2026. It reflects the current state of regulatory proposals — not all of these will result in bans, and timelines will shift. But the direction of travel on each is established and consistent with the broader trajectory of cosmetics regulation toward eliminating endocrine-active, persistent, and genotoxic substances.
The most reliable early warning system for your specific formula is to run it against the current regulatory database regularly — not just at launch, but on a 6-month cycle. Regulations that don't affect you today may affect you at your next production run.
