We have used Emsworth Stability Plus for several years. They are extremely reliable and exceptionally helpful. They are also very competitively priced. They did stability work for us for our Biocide Product Regulatory submission and not only was the work of the highest quality but the costs compared to other companies who offer such work for Biocidal products was very competitive. I do not hesitate to recommend them.

Emsworth have been looking after our products since the launch of our FARMERS’ Welsh Lavender body care line six years ago. Their stability and compatibility testing is very thorough and as swift as it can be. We always appreciate the way they’re happy to keep us posted during the testing period so we have some idea of the outcome. This is helpful with production planning and product launch dates. They’re also very well connected throughout the world of testing, so useful when other specialist advice is needed. On top of the excellent service they provide they are a delight to work with.

‘As manufacturers of high quality Personal Care Products and Private Label formulations for skin, hair and body care we require any third party testing to be carried out to the highest standards. We have regularly outsourced stability and compatibility projects to ESP and have been very pleased with the professional, efficient and helpful service we have received. We will continue to use them in the future.’
