Ajinomoto Develops New Manufacturing Method for Palm Oil-Free, Amino Acid-Based Bio-Surfactant

※1) Refers to "Bioacyl Glutamate" Ajinomoto Co., Inc. (President: Shigeo Nakamura, Headquarters: Chuo-ku, Tokyo) has developed a new manufacturing method using fermentation technology that uses only sugars stably procurable worldwide as raw materials for amino acid-based surfactants, which traditionally use fatty acids derived from palm oil (patent pending). This technology enables the provision of amino acid-based bio-surfactants (surfactants produced by microorganisms) that do not use petroleum-derived raw materials or palm oil. By leveraging this technology, we have solved the color and odor issues that were challenges with conventional bio-surfactants and achieved higher foaming performance. Through environmentally conscious manufacturing technology that utilizes sustainable raw materials, we promote the development of high-performance materials and will continue to provide consumers with gentle and comfortable products.

In recent years, transformations in raw materials for cosmetics and detergents are also being called for to realize a sustainable society that includes consideration for the environment. Palm oil, in particular, is widely used around the world, but environmental and social issues such as the reduction of tropical rainforests due to production expansion, the resulting increase in carbon dioxide emissions, and human rights issues for workers on plantations have been pointed out internationally. There are also supply constraints, as palm oil production is limited to warm, rainy regions within 10 degrees latitude. Against this backdrop, research is underway to reduce the use of palm oil and select alternative sustainable raw materials※2. ※2) Source: WWF-Report-Palm-Oil-Searching-for-Alternatives.pdf

Bio-surfactants produced by microorganisms are attracting attention due to their natural origin, high biodegradability, and low environmental impact. The market is rapidly expanding against a backdrop of technological innovation and cost reduction. Currently, the global bio-surfactant market is expected to grow at an annual rate of 13% from 2021 to 2030※3. However, conventional bio-surfactants have had challenges in terms of weak foaming, coloration, and residual odor, making them difficult to use in cosmetics※4. "Bioacyl Glutamate," manufactured by the new fermentation method developed this time, is a type of amino acid-based surfactant, and is the result of our company's research and development, leveraging our knowledge and know-how in AminoScience®, taking into account market needs and technical challenges.
