Green Science Alliance has developed a gel nail polish made from plant biomass. The formula is free of TPO, HEMA and TMPTA, three ingredients common in conventional gel nail products.
Researchers Hirotoshi Umemoto and Ryohei Mori, both PhDs in engineering, led the bio-based development.Â
The three excluded chemicals each carry known risks. TPO, a photopolymerization initiator, is banned in Europe over reproductive toxicity concerns. HEMA can trigger skin irritation and allergic reactions. TMPTA has been reclassified as a Category 2 carcinogen under EU rules, and the IARC lists it as a possible carcinogen.
Gel nail products free of both TPO and HEMA already exist. But bio-based versions that also avoid both compounds remain rare worldwide, according to the company.
The new polish currently contains 22% to 25% biomass content. Green Science Alliance plans to increase that share over time.
The product fits into the company’s wider push to replace petroleum-based materials with plant and biomass alternatives. Green Science Alliance has already developed biodegradable resins, bioplastics, bio-based coatings, adhesives and nanocellulose from wood waste and other organic sources.
Petroleum-based plastics add to atmospheric CO2 during production and contribute to plastic pollution after disposal. Bio-based materials, by contrast, can offer lower net emissions since the plants they’re made from absorb CO2 as they grow.
Green Science Alliance said it will accelerate rollout of the new gel nail polish in Japan and international markets.
