Novaguard UG (Undecenoyl Glycine) is an amino acid derivative that offers antimicrobial, skin-conditioning, and emulsifying properties. Derived from undecenoic acid and glycine, this ingredient is commonly used in personal care products to balance sebum production, promote skin clarity, and enhance the preservation system. It is effective in both oily and acne-prone skin formulations due to its ability to regulate sebum without causing irritation.
