Skin irritation


RAW MATERIALS / VALIDATED TEST METHOD (under OECD Test Guidelines 439)

   

 

 

DESCRIPTION

Our epidermal models and corresponding protocols are designed for regulatory purposes to classify and label chemicals regarding in vitro skin irritation assessment.

In case of irritant test substance, an additional run using in vitro skin corrosion test method may be required when data are generated in the context of OECD TG 439.

 

 

MODELS

EpiSkinTM Small model

SkinEthicTM RHE
                                                                                         

 

PROTOCOL PRINCIPLE

 Both EpiskinTM Small Model and SkinEthicTM RHE model can be used for in vitro skin irritation assessment but they should be used with their respective protocol.

 

DETAILED ASSAY PROCEDURE

NB: please note that this protocol is currently under revision in order to meet OECD TG439 version 2015; website news will  will keep you informed of new updated protocol version. Do not hesitate to get information on our training sessions or to contact our technical support.
