Summary of 2024 UK Cosmetics Regulatory Developments

The UK cosmetics regulations were first introduced in 1978 and have undergone multiple revisions, including the latest amendments following Brexit in 2021. The current version of the regulations is based on the EU Cosmetics Regulation (EC) No. 1223/2009, with additional UK-specific requirements. Businesses operating in the cosmetics sector in the UK (England, Scotland, and Wales) must comply with the relevant regulations.

This article summarizes the latest developments in UK cosmetics regulations in 2024, as well as the scientific advice issued by the UK Scientific Advisory Group on Chemical Safety of Non-Food and Non-Medicinal Consumer Products (SAG-CS). The aim is to help businesses stay informed about the latest regulatory changes, ensure compliance, and successfully enter the UK market.

The Scientific Advisory Group on Chemical Safety of Non-Food and Non-Medicinal Consumer Products (SAG-CS) is an independent scientific advisory body responsible for assessing the safety of chemical substances in non-food and non-medicinal consumer products. It provides scientific advice and risk assessments in the fields of public health and consumer safety to the Office for Product Safety and Standards (OPSS).

Cosmetics and their ingredients, such as nanomaterials, hair dyes, preservatives, UV filters, colorants, and fragrance ingredients.
Other non-food and non-medicinal consumer products, such as toys and textiles.

The recommendations provided by SAG-CS contribute to policy development, ensuring consumer health and safety while also promoting industry compliance.
