This standard specifically covers hair dyes based on para-phenylenediamine (PPD)/ aryl amine. The BIS has also prescribed standards for other types of hair dyes. IS 10350:2019: Specification for powder hair dyes IS 15205:2005: Specification for oxidation hair dyes (emulsion type) It’s important to note that the manufacturer is at liberty to describe their ‘Hair Dye’ product as ‘Hair Colour’ or ‘Hair Colorant’, since ‘Hair Dye’, ‘Hair Colour’, and ‘Hair Colourant’ are synonyms Please have a look at our website www.tamilnadutesthouse.com for further details and mail us to info@tn-th.com
