Cosmetic, Beauty, Healthcare Products Testing

MB Research has been conducting product safety assessments for the cosmetics, personal care, chemical and pharmaceutical industries for over 40 years and is often sought out by Cosmetics Industry Leaders to ensure the safety their ingredients and aid in the rapid development of products.

MB Research Scientists develop and conduct in vitro and alternative toxicology testing assays such as nitric oxide production, melanin transfer, cell proliferation, apoptosis, ocular irritation, dermal irritation, phototoxicity, angiogenesis / antiangiogenesis and corrosivity.

We are a leader in the use and development of In Vitro and Alternative Toxicology Tests and continue to introduce new testing methods regularly.

More information about specialized research projects is available by calling us directly and speaking with Client Services.

Cosmetic, Beauty and Healthcare product industries are subject to global regulatory requirements such as the EU Cosmetics Directive (76/768/EEC) in response to growing concern over the safety of cosmetic products and their ingredients.

Ocular Irritation Assays

Three Dimensional Human Ocular Tissue Equivalent Systems

MatTek EpiOcular™, SkinEthic corneocyte models

  • These models mimic characteristics of the epithelium of the eye
  • Unique properties of 3D models allow test articles to be applied topically, allowing testing of solids, organics, and insoluble materials

Alternative Ocular Irritation Test Methods

HET-CAM - Hen's Egg Test - Chorioallantoic Membrane (HET-CAM)

  • Uses fertilized chicken eggs

Chorioallantoic Membrane Vascular Assay (CAMVA)

  • Uses fertilized chicken eggs on embryonic day 10 or 14 of development
  • Measures hemodynamic effects, injury, and anti-angiogenic effects to the membrane microvasculature
  • Especially useful for alcohol-containing formulations

Bovine Corneal Opacity and Permeability Assay (BCOP)

  • Uses excised bovine corneas that are normally discarded as waste in food production
  • Measures two endpoints; 1) changes in opacity, reflecting protein denaturation and corneal injury, and 2) fluorescent dye permeability reflecting damage to corneal epithelium
  • Optional histological endpoint is available (H & E staining)
  • Measurement of pro-inflammatory mediators in liberated corneal cells (by flow cytometry or ELISA)

Porcine Cornea Reversibility Assay (PorCORA)

  • Uses excised porcine corneas that are normally discarded as waste in food production
  • Corneas maintained in culture for up to 21 Days
  • Measures "Days to Recover" after exposure to possible Irritants
  • Allows discrimination between Severe Irritant and Ocular Corrosive

Keratinocyte/Fibroblast Viability Assay (Neutral Red or MTT)

MB Research uses normal human primary epidermal keratinocytes or fibroblasts (or mouse keratinocytes and fibroblasts)
  • Cells are representative of the eye and skin epithelium
  • Human cells are derived from neonatal, adolescent, or aged donors
  • Cytokine expression or release (LDH, PGE-2, interleukins) can be measured
  • Low serum or serum free protocol options are available

Keratinocyte Proliferation (turnover) Assay

  • Using primary human cell or mouse cell lines in serum-free or low serum media
  • Rate of proliferation or apoptosis is measured by vital dye uptake (MTT or neutral red) or by BrdU incorporation and flow cytometry

Dermal Irritation Assays

Three Dimensional Human Skin Equivalent Systems

The 3D models available at MB Research (MatTek EpiDerm™ and SkinEthic systems) allow the application of the test material directly to the "skin" surface and permit the assessment of dermal toxicity via a wide variety of parameters.

  • In Vitro Skin Irritation: Reconstructed Human Epidermis (RHE) Test- OECD TG 439
  • Cytotoxicity via MTT, neutral red viability assay, or flow cytometry
  • Histological examination (H & E) of the epidermal layers, including the stratum corneum
  • Measurement of inflammatory mediator and lytokine release (PGE-2, nitric oxide, TNFa, IL1a, and other interleukins)
  • Dissolution of the tissue equivalent into a single cell suspension, with subsequent flow cytometric analysis allows evaluation of gene expression and peroxide production (antioxidant status of cells)

Dermal Corrosivity Assays


  • An accepted alternative to the Draize rabbit corrosivity test that recently has been validated by ICCVAM for use for DOT, FHSA, CPSC, EPA and FDA testing
  • Allows Packing Group assignment of test materials
  • Can be used to compare the relative corrosivity of materials within Packing Groups for product development purposes. See for more information.

MatTek EpiDerm™ Corrosivity Test- OECD TG 431

  • Validated by ECVAM and ICCVAM as an in vitro alternative corrosivity test based on human skin cells
  • Allows testing of material not compatible with Corrositex™

Back to top

Phototoxicity Assays

  • With 3T3 mouse fibroblast cells via the EC/COLIPA validated protocol. See for more information.
  • Using the MatTek EpiDerm™ protocol currently under review by ECVAM
  • Human keratinocytes or fibroblasts
