The ingredient, gamma polyglutamic acid, joins the company's Tego range that was created in December 2007 with four Indian-sourced ingredients. Fermented soybean Tego Cosmo PGA is a polypeptide of the amino acid L-glutamic acid which can be found in fermented soybean, known as 'natto' in Japan where it is consumed for its health benefits. When added to cosmetics formulations the ingredient has good film forming and moisturising properties and can therefore add sensory benefits to the product, according to the company. In addition, it can help the absorption and bioavailability of positive ions such as calcium and magnesium, maintain Evonik. The ingredient can also be used as an additive to nutritional supplements as it can facilitate calcium absorption when ingested, increasing the efficacy of the supplement against conditions such as osteoporosis. The extract is produced by biotechnology involving the fermentation of the L-glutamic acid using Bacillus subtilis natto - the microorganism used to prepare natto. In an attempt to capitalise on the trend for sustainability the company stress that the ingredient is edible, non-toxic to the human body and biodegradable. Sabinsa partnership extension Cosmo PGA's addition to the Tego range closely follows two other ingredients that were launched by the company in April 2008. The horse chestnut extract called Venocin and the acid obtained from Santalum album seeds (a relative of the sandalwood tree) were the result of an extension with the company's Indian partner Sabinsa. The horse chestnut extract benefits those suffering from skin imperfections such as varicose or spider veins, and the Santalum album seed extract adds anti-inflammatory properties to formulations, according to the company.
