Japanese household goods maker Kao Corp may soon be using algae to produce cleansing agents for its products, specifically shampoo. Kao found two types of algae among nearly 1,200 species in its research into more sustainable raw materials for its products, Xinhua reported, citing a report in Japan’s Asahi Shimbun newspaper.
The algae to be used contain medium-chain fatty acids, which are similar in structure to those of palm kernel oil, used as a raw material for surfactants, the main component in shampoo. Surfactants or surface-active agents have the ability to remove dirt. Surfactants that Kao Corp uses are produced from particular types of medium-chain fatty acid.
Kao presented the findings at an academic meeting related to fats and oils in the city of Sapporo on September 9. As palm kernel oil is extracted from oil palm seeds, concerns have been raised about deforestation for the purpose of planting palm trees, especially in Southeast Asian countries. Palm fruits are also used as a food source.
Kao has been seeking alternative materials for producing surfactants, which used to be made from petroleum prior to palm kernel oil. “We had been working on switching from petroleum-based materials to natural materials,” said a Kao spokesperson. “But we now want to focus on non-edible materials to promote a more sustainable society.”
Going forward, Kao will research cost-effective means of producing large amounts of surfactants. This will involve experimenting with how to increase the amount of algae, while effectively extracting medium-chain fatty acids. The company aims to finish the basic research by 2020, after which it will take steps toward commercialising algae-based products such as shampoo. This work was recently presented at the European College of CNP Congress in Berlin.
