The 12 Principles of Green Chemistry were introduced in the late 1990s as a collection of ways to reduce both the environmental impact and the potential negative health effects of chemicals and chemical synthesis.4 The polyester ingredients discussed here were designed and manufactured according to many of the Principles of Green Chemistry. The starting materials are benign to both the environment and human safety. The polymers that result are equally nontoxic to humans and the environment. LexFeel Vibrant is partially derived from palm acid which is responsibly sourced according to the RSPO Mass Balance supply chain. During production, a one-pot solvent-free process is employed and this process produces no waste. The only by-product is water. The resulting polyesters are biodegradable and contain >70% biobased content. By using these novel polyesters in colour cosmetic applications, consumers can trust in the safety and low environmental impact of the ingredient and receive the strong performance benefits they expect.
