The UK Cosmetic, Toiletry and Perfumery Association (CTPA) has held its first-ever scientific conference in London, a sold-out, member-only event staged under the theme 'Aligning Science, Policy and Consumer Perception'.

The programme put a spotlight on where scientific evidence, regulatory decision-making and public understanding collide — a pressure point for formulators and compliance teams working in an era of information overload and widespread misinformation about chemicals in cosmetics.

Speakers came from across the regulatory and industry ecosystem:

• Experts from the UK government
• International and European cosmetic and personal care associations
• Cosmetic companies
• Academics
• Journalists and communications consultants

Through presentations, interactive workshops and panel discussions, the event covered five scientific and regulatory topics with direct consequences for product development and compliance workloads.

What did the agenda cover?

The conference programme addressed:

• Hazard versus risk — how consumers understand and respond to information about chemicals, including the critical distinction between the two concepts that so often gets lost in public debate.
• Science-based policy — the latest developments in regulation shaping the cosmetics sector.
• Animal-free safety assessment — building confidence in next-generation approaches that will define how safety dossiers are compiled.
• UV filters and the marine environment — the cutting-edge science behind UV filters and what the evidence says about their environmental impact.
• Science communication — how effective communication can build trust and confidence among consumers and the media.

For formulation and regulatory teams, each of these tracks maps onto live workstreams. The hazard-versus-risk discussion addresses a recurring reputational problem: consumer campaigns that treat intrinsic hazard as proxy for real-world exposure risk, which can drive ingredient removal decisions ahead of any regulatory requirement.

The animal-free safety assessment session reflects the sector's ongoing transition toward new approach methodologies, where confidence among regulators and safety assessors determines how quickly such methods gain acceptance in dossiers.

What did CTPA say about the event?

"The event demonstrated the value of collaboration between scientists, regulators, policymakers and communications professionals in addressing important issues such as public understanding of science, trust in evidence, and the role of robust scientific data in informed decision-making," said CTPA's science director Caroline Rainsford.

"At a time when misinformation can spread quickly, open discussion and clear communication are more important than ever. CTPA will continue to work on fostering collaboration across the scientific community to promote evidence-based approaches and support greater understanding of the science behind, and safety of, cosmetics and personal care products," she added.

Rainsford's framing signals the association's read on where the sector's credibility battle sits: not primarily inside the laboratory, but in the space between evidence and public perception. That has practical implications for procurement and brand communications teams, who increasingly face questions from retailers and consumers grounded in misread hazard data rather than risk assessments.

Why does a first-time conference matter for the trade?

A sold-out debut on this agenda tells its own story. UK-based formulators, safety assessors and regulatory affairs professionals packed the room for sessions on exactly the topics generating the heaviest compliance and communication load — UV filter environmental data, animal-free assessment acceptance, and consumer-facing chemical literacy.

The involvement of UK government experts alongside European and international association representatives also matters post-Brexit, when UK and EU regulatory pathways can diverge and industry needs forums where both sides of the channel share evidence bases.

The member-only format suggests CTPA sees scientific and regulatory intelligence as a core benefit of membership, positioning the conference alongside its existing advocacy and technical work as a venue where regulators, academics and industry confront shared problems directly.

What comes next?

CTPA has committed to continuing its work fostering collaboration across the scientific community to promote evidence-based approaches. Watch for follow-up outputs from the conference sessions — position papers, guidance or workshop materials on hazard-versus-risk communication and animal-free safety assessment — as the association converts the event's discussions into member resources, and for the announcement of a second edition given the first outing sold out.
