There’s a lot of room for interpretation in this description, so how can a cosmetic formula be developed to meet a green definition...
Polyquaternium-74: An Advanced Hair Conditioning Polymer (pg 53)
Eric Leroy, Rhodia Research
Polyquaternium-74 is a synthetic high performance conditioning polymer whose flocculation and deposition characteristics enable it to match or outperform traditional conditioning polymers in detangling, overall hair conditioning, shine enhancement and buildup reduction when combined, as shown here, with a submicron dimethicone emulsion. Benefits are noted for 2-in-1 shampoo formulations...
Hair and Amino Acids (pg 61)
Eiko Oshimura, PhD, Ajinomoto Co., Inc.
Amino acids are taken up by hair and assist in improving hair surface hydrophobicity, tensile strength and luster. This article discusses interactions between amino acids and hair...
Greening Personal Care Chemistry (pg 69)
James H. Clark and Louise Summerton, Green Chemistry Centre of Excellence
Multiple economic, legislative and customer pressures are forcing an unprecedented level of change in chemical manufacturing and the design of chemical products. The authors examine the drivers for change and opportunities across the product lifecycle for green and sustainable chemistry including the use of renewable resources, cleaner synthesis methods and greener products...
Natural Preservation from Concepts in Nature (pg 81)
Fernando Ibarra, PhD, Dr. Straetmans GmbH and Christopher H. Johnson, Kinetik Technologies Inc.
