Polyglutamic acid (CAS 25513-46-6) is usually in the form of white powder.
Polyglutamic acid is a high molecular compound with good water solubility and biocompatibility.
It has many excellent properties, such as water retention, plant growth promotion, and improved fertilizer utilization. In the agricultural field, it can be used as a fertilizer enhancer, water retainer, etc., which helps to improve the fertility and water retention capacity of the soil and promote the growth and development of crops. For example, adding it to fertilizer can reduce fertilizer loss and improve the effect of fertilizer.
In the field of cosmetics, polyglutamic acid is also used, because its moisturizing properties can be used in skin care products.
