Product Highlights

Strat-M Transdermal Diffusion Membrane

Ethical and regulatory pressures have limited testing of personal care formulations on human or animal skin which has driven the need for access to alternative models.

Strat-M is a synthetic, non-animal based model for transdermal diffusion testing that is predictive of diffusion in human skin without lot-to-lot variability.

Organotypic 3D Skin Cultures

Animal models have gradually been replaced by “cruelty-free” in vitro organotypic skin models that use primary human cells and cell culture inserts to recapitulate the stratified epidermal architecture.

We have developed a simple step-by-step culture protocol that can be used to generate human epidermal skin models using primary human keratinocytes (PHK), dermal fibroblasts (primary human fibroblasts, PHF), collagen-coated MilliCell culture inserts and the proprietary 3dGRO Skin Differentiation Medium which supports the robust differentiation of keratinocytes during the air:liquid interface culture steps.

Immunoassays for Protein Biomarker Analysis

Protein biomarker immunoassays characterise the interactions between a biological system and a potential hazard. Our industry-leading range of single (ELISA), multiplex (MILLIPLEX) and ultra-sensitive (SMC) immunoassays allow direct monitoring of the biological effects of cosmetic products by assessing markers of inflammation, sensitisation, aging and tissue regeneration among others.

Standards for Cosmetics & Personal Care Products

Due to growing regulations and banned ingredients, using analytical standards is key to ensuring the safety of your next formulation. Our standards manufacturing sites are accredited to ISO/IEC 17025, ISO Guide 34/ISO 17034, which is the highest achievable quality level for reference material producers. Because our high standards match yours.
