MSL extends its GMP expertise to support small-batch cosmetic manufacturers

Published: 3-Feb-2026

MSL’s CleanSure Hygiene Auditing Solution combines surface swabbing with air plate testing to assess both environmental and airborne microbiological testing, giving smaller, home-based producers a practical, evidence-based way to monitor hygiene in kitchens, studios, and small workspaces where full GMP infrastructure isn’t feasible

Leading regulatory and microbiological testing house MSL Solution Providers has expanded its CleanSure Hygiene Auditing Solution to include air quality testing. While the company already delivers comprehensive GMP environmental monitoring for larger cosmetic brands and manufacturers, CleanSure applies the same underlying principles in a format designed specifically for home‑based and small‑batch cosmetic producers.
MSL’s CleanSure Hygiene Auditing Solution combines surface swabbing with air plate testing to assess both environmental and airborne microbiological testing, giving smaller, home-based producers a practical, evidence-based way to monitor hygiene in kitchens, studios, and small workspaces where full GMP infrastructure isn’t feasible.

Quick, reliable, and effective, the service uses postal microbiological testing, drawing on the company’s extensive microbiology and industrial hygiene expertise. The enhanced service includes:

  • Surface swabbing for microbiological contamination
  • Air plate testing to detect airborne moulds, yeasts, and bacteria
  • Clear, UKAS aligned reporting within 3–5 days
  • Actionable recommendations to support hygiene improvement and prevent contamination

This dual approach gives small cosmetic makers a more complete picture of their production environment, helping them maintain hygienic conditions, validate cleaning protocols, and demonstrate due diligence during audits and inspections. The process is straightforward, with reports issued within 3 – 5 days of samples being received. Alongside the results, clients receive tailored recommendations to help them stay ahead of any potential hygiene problems. 

Peter Thistlethwaite, technical manager at MSL Solution Providers, comments, ‘We’ve supported GMP regulated manufacturers for years, and the principles of good environmental hygiene don’t change just because production happens in a smaller space. CleanSure adapts those same standards for home based and small batch makers, giving them a practical way to monitor both surface and airborne contamination without specialist equipment.’

Beyond CleanSure, MSL delivers full GMP aligned environmental monitoring, consultancy, and training for established cosmetic manufacturers. As one of the UK’s leading regulatory and laboratory testing houses, its inhouse accredited labs provide a comprehensive range of standard tests, including challenge/preservative efficacy testing (PET), stability testing, and pack performance and compatibility testing. It supports businesses of all sizes, from SMEs to blue chip cosmetic manufacturers internationally.
