MSL offers a seamless, integrated approach, resulting in products and services getting to market quickly, compliantly, and cost effectively, whilst still ensuring the highest standards of testing.

Regulatory Support


MSL fully understands the role of the Responsible Person within Cosmetic Regulation 1223/2009 and can either adopt that position for a brand or manufacturer or alternatively advise clients on the actions necessary if they wish to act as RP for their own products (if possible).

Since UK companies are no longer legal entities within the EU post-Brexit, MSL has a wholly owned subsidiary business in Dublin, Ireland, which can take on this role. Similarly, thanks to its Greater Manchester-based HQ, it will be able to act as the UK Responsible Person for EU businesses wishing to trade within the UK too. MSL is therefore able to offer a dual Responsible Person service, helping companies gain regulatory compliance and seamless entry to both the EU and UK markets without having to deal with multiple service providers.

MSL holds full insurance cover for its Responsible Person services, and its complete EU Cos Reg process is ISO9001 accredited. MSL operates a fully secure data retrieval, storage and management system and regularly work to NDAs/CDAs.
