MSL is a consultancy specialising in the regulatory compliance and microbiological testing of cosmetics and personal care products


MSL is a consultancy, based in the UK, which specialises in the regulatory compliance and microbiological testing of cosmetics and personal care products. It has a customer base spanning five continents that includes raw material suppliers, finished product manufacturers and brand owners.

As the UK’s largest 3rd party Responsible Person and offering ISO 9001 and insurance backed regulatory services MSL is ideally placed to support your compliance needs. As well as consultancy, MSL has a host of other linked disciplines offered by our in-house UKAS accredited laboratory including microbiological testing, claims substantiation, auditing and user trials.

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).

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.

As well as Responsible Person, MSL can provide all other services you may require, ensuring your products are compliant with the European Cosmetic Regulation including:

  • Cosmetic Product Safety Reports (CPSRs)
  • Artwork/Packaging review
  • CPNP Notification
  • Formulation Reviews
  • PIF Collation and Maintenance
  • Cosmetovigilance
  • Safety Data Sheets.


MSL has expertise with the US Food, Drug & Cosmetics Act as well as state legislation including California’s Proposition 65. Drawing on this experience, MSL can offer:

Regulatory Compliance

  • Labelling Reviews
  • Formulation Reviews (Federal and State requirements)
  • Proposition 65 Reviews
  • Supply Chain Management Schemes i.e. WERCS.

Product Testing

  • Preservative Efficacy (Challenge) testing (USP 51)
  • Stability testing
  • Microbial Limits (USP 61 & 62)

MSL has expertise with the Canadian Food and Drugs Act and the Cosmetics Regulations. With this, it can offer:

  • Formulation Reviews – Cosmetic Ingredient Hotlist
  • Health Canada Notification.


MSL can help businesses prepare for Brexit, and indeed, has helped more than 100 companies do so. The most notable issues raised involve CPNP notification transfers, re-labelling and the requirement for a suitable 'Responsible Person' as a legal entity to represent UK cosmetic businesses within the EU community.

Since UK companies will no longer be 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.
