This project provides recommendations for finding safer preservatives for laundry detergent, hand soap, and dish soap, aiming to replace phenoxyethanol. It looks for alternatives that are just as effective, or even better, but with fewer health and environmental risks....
Quaternary ammonium compounds (quats), like behentrimonium chloride (BTAC) and cetrimonium chloride (CTAC), are commonly used in hair conditioners to make hair smooth, glossy, and easier to comb. However, these compounds pose significant health and environmental risks. L'Oréal is working on finding safer, more biodegradable alternatives, but this is a challenge across the industry.
In this first cohort of Berkeley Changemakers Green Materials Innovation undergraduate course, student teams partnered with Black Women for Wellness to investigate safer alternatives to sodium hydroxide & phthalates in hair relaxers.
In partnership with the California Dept. of Toxic Substances Control and L’Oreal, this student team was tasked with identifying safer alternatives to previously used “bad actor” chemicals, such as toluene, in nail polish formulations.
The Safer Sunscreens group identified naturally-sourced compounds such as colorless carotenoids, mycosporine-like amino acids, and vitamin E compounds, for use as potential alternatives to existing sunscreen compounds. These substances may serve as viable alternatives to the benzophenone compounds recently banned in the State of Hawaii. The team based its research on plant and microbial approaches to UV protection. The group also considered the properties of compounds that have been accepted for use in Europe, but not in the United States, with an aim to identify the...
The product packaging researchers identified biopolymer films for product packaging for a range of Method Home products, including laundry powders, detergents, and soaps, with a range of moisture barrier needs. The team came up with strategies that fell into three categories: Biopolymer films derived from natural sources, including chitosan, pectin, and gelatin; chemical additive cross-linking film to improve barrier and mechanical properties, including with genipin and ferulic acid; and physical additive nanofillers to reinforce film’s barrier and mechanical properties,...
This team was challenged to assess current laundry detergent formulations and propose strategies for laundry detergents that work effectively in cold water, low-energy wash cycles. Partners on this challenge included Method and Seventh Generation, who are both seeking industry-wide solutions to this challenge, and Amyris and BioAmber, two companies who are developing innovative, sustainable, and green ways to produce chemicals.
