Technology Features & Specifications
The technology involves the structural modification of PPD. Among the PPD derivatives, a few promising candidates showed a reduced sensitizing potential in the Direct Peptide Reactivity Assay (DPRA, recognized by the OECD guidelines as a test to predict skin sensitization), stably coloured bleached hair samples without staining the skin and confirmed minimal penetration through the skin in ex vivo skin penetration studies.
Potential Applications
To replace PPD in PPD-containing products such as:
- Hair dyes
- Textile dyes and fur dyes
- Dark coloured cosmetics
- Photographic developer and lithography plates
- Photocopying and printing inks
- Black rubber
- Oils, greases and gasoline
Market Trends and Opportunities
The global dyestuff market is expected to grow at a compound annual growth rate of 8.8% to USD 306.2 million by 2025. There is currently no dye product that can claim to be hypoallergenic. In view of the growing market of beauty and personal care technologies, our technology provides huge commercial potential for consumer-friendly cosmetic products.
