About us

We formulate, develop and test the product on the inside, so your product is ready for launch on the outside.

What we do

From concept to manufacture and fulfilment we offer an unrivalled level of industry knowledge and expertise.

Founded in 2008, we are Chartered Chemists, Toxicologists, Microbiologists, Analysts and Regulatory experts specialising in the provision of formulation and testing services to clients within various industries including cosmetic, supplement, and household products.

We have exceptional expertise and complementary skills in manufacturing, process controls, industry regulation, health and safety, marketing, and project management. We are with our clients every step of the way to see their product through to successful market launch and sustainability.

When required we partner with our clients to provide technical consulting. We very often help clients fill any gaps in their knowledge base and provide a fresh perspective and strategy on the best way to improve their production line.

Formulation & Development

We develop cosmetic, household, and food products from concept to manufacture, or refine existing formulations to meet regulatory and consumer needs. Our expertise includes formulation development across skincare, hair care, cleaning solutions, candles, fragrances, and supplements, with specialist capability in infant, vegan, and sensitive-skin products.

Alongside formulation, we provide stability studies, compatibility testing, and packaging durability assessments to ensure your product performs as intended. We also guide clients through regulatory compliance, helping to navigate EU, UK, and global requirements. For those ready to scale up, we offer manufacturing support, pilot runs, and specification testing—giving you confidence your product is safe, effective, and market-ready.

Each service is delivered in line with UK, EU, and international regulations, with ingredient evaluation supported by our in-house NOAEL and SED databases to ensure accurate Margin of Safety calculations and fully evidenced outputs. This gives you the assurance of robust, regulation-ready reports across all key areas of product safety and compliance.

If you’re developing a cosmetic product, you’ll know that product testing and clinical trials are essential. Any claims you make must be substantiated in line with regulations such as Commission Regulation (EU) No 655/2013.

At our UK DermaCentre, we provide a full suite of claim substantiation studies using state-of-the-art technology. Services include SPF Testing and Clinical Sunscreen Testing Studies, Ophthalmology and Periocular Acceptability, and Consumer User Trials. We also offer specialist assessments such as Gynaecologically Tested and Dermatologically Approved evaluations.

Our team conducts detailed measurements including patch testing, skin moisture and TEWL assessments, erythemal index and melanin testing, SPF, elasticity and sebum analysis. This ensures your products meet safety standards, deliver validated performance, and inspire consumer confidence.
