A Pioneer

The Ajinomoto Group entered the Cosmetics and Toiletries Ingredient business with the launches of Ajidew® humectants in 1971 and Amisoft® surfactants in 1972. The base material for these products is monosodium glutamate (MSG) made with a fermentation method that uses plant-based raw materials.

Weakly acidic, safe for human use and highly biodegradable, Amisoft® started to enhance facial cleansers, shampoos and bar soaps. Products containing this new material were powerful in use and gentle for the environment. To this day, AMISOFT’s natural biocompatibility makes it one of the industry’s safest surfactants.

Since then, additional personal care ingredients made from various amino acids were launched by Ajinomoto, Co. They offer new options and have been used as ingredients in a wide range of cosmetics and toiletries that follow the concept of being environmentally friendly and mild to skin, thus opening up the new field of amino acid-based personal care ingredients.

Amino acids are essential for good skin and hair

Nowadays, many products such as shampoos, conditioners, and body washes advertise that they contain amino acids. Products formulated with amino acids offer a number of benefits. Amino acids are critical to the natural moisturizing factor (NMF) of the stratum corneum of the skin. When the cells in the epidermis die and become the stratum corneum, the proteins in these cells are broken down into amino acids and supplied to the stratum corneum. Roughly half of the NMF of skin consist of amino acids and pyrrolidone carboxylic acid (PCA). PCA comes from the amino acid glutamic acid.

Skin is naturally somewhat acidic with a pH of 5 to 6. Washing your hands repeatedly with alkaline soap increases the alkalinity of your skin and is the main reason of its roughness. Amino acid-based soaps and liquid handwashes are working optimally in mild acidic or neutral conditions. They clean your skin while maintaining its natural pH.
