One of the most important steps in development is to confirm the safety of your product and we have a variety of standard methods available. Our database can also provide standard or more sensitive volunteers to suit your specific requirements.

Primary Irritation

24, 48, 72 or 96-hour patch tests to screen for irritation potential

Cumulative Irritation

21-day patch test to investigate potential irritation from chronic exposure

Repeat Insult Patch Tests: Sensitisation

100 or 200 subject patch test to investigate sensitisation (allergy) potential following repeated exposures and a challenge at a naïve site

Phototoxicity & Photosensitisation

Screening test for irritancy and/or allergy potential following exposures to UV light

Comedogenicity

Screening test for potential of a product to promote the formation of comedones (“blackheads”) following chronic exposure

Soap Chamber Tests

Benchmarking test for mild surfactant products, based on the Frosch & Kligman method

In-Use Safety

Provides reassurance that products do not cause adverse reactions under normal use conditions

Ocular Irritation

Screening test; products are applied around or directly into the eyes, under supervision of an ophthalmologist

Exaggerated Use

Provides reassurance that products do not cause adverse reactions, under most use conditions
