Product Overview

L-Pyroglutamic Acid, with the CAS number 98-79-3 and also referred to as L-5-oxoproline, is a naturally occurring cyclic amino acid derivative derived from L-glutamic acid. Typically produced through biological fermentation, it serves as a crucial constituent of the skin’s natural moisturizing factor, offering exceptional skin hydration and humectant capabilities. It is primarily utilized as a functional ingredient in cosmetic skincare formulations, as well as in functional foods and nutritional supplements, owing to its remarkable water-binding capacity and favorable biocompatibility.

 

Character

L-Pyroglutamic acid is a cyclic derivative of L-glutamic acid. It is freely soluble in water, and maintains stable chemical properties under normal storage conditions. It exists naturally in fermented food and human skin natural moisturizing factor (NMF). It has strong water retention capacity and low skin irritation, ideal for cosmetic and food raw material applications.

Main Functions

1.Powerful humectant: binds water molecules to maintain skin hydration, one of natural skin moisturizing ingredients

2.Nutritional fortifier for functional food and nutritional formulations

3.Formulation stabilizer, improves the stability of cosmetic & food systems

4.Biochemical intermediate for amino acid related synthesis

 

Applications

 

1.Cosmetic & personal care: moisturizing serum, cream, lotion, skincare raw materials

2.Food industry: functional food additives, dietary supplement raw materials

3.Biochemical field: biochemical synthesis intermediates and research usage
