Products Description

Copper PCA (Copper Pyrrolidone Carboxylate) is a high‑efficiency cosmetic active ingredient combining natural moisturizing factor PCA and essential trace element copper. It delivers superior antioxidant, repairing, anti‑aging, oil‑controlling, and soothing properties, widely used in high‑end skincare, hair care, and after‑sun products.
Copper PCA is a water-soluble bidentate chelate complex formed via coordinate bonding between divalent copper ion (Cu²⁺) and two molecules of L-Pyrrolidone-5-Carboxylic Acid(PCA, endogenous natural moisturizing factor of human stratum corneum). Its in-vitro & in-vivo biological efficacy derives from two core structural components with independent synergistic biochemical mechanisms:

Product Application
Color enhancer
Copper pyrrolidone carboxylate significantly enhances the color rendering effect of dyes or pigments on the skin by complexing with nitrogen-containing water-soluble small molecules such as amino acids, urea, etc. The ratio range is 30:1 to 3:200 (copper pyrrolidone carboxylate: water-soluble nitrogen-containing small molecule).
Application of external dosage forms
Swertia sinensis bitter glycoside has a promoting effect on hair growth. Japanese research has shown that it can effectively stimulate hair follicles and is suitable for use in hair growth products to help improve hair loss problems.
Others
1. Helps repair damage to the skin's protective barrier
2. Provide immediate refreshing hydration
3. Improve skin elasticity and firmness
4. Enhance the glossiness and radiance of the skin
5. Suitable for sunburn/erythema.

Frequently Asked Questions
What core chemical structure makes Copper PCA stable in cosmetic pH5.0~7.0 aqueous formula?
-
Copper PCA forms stable coordinate chelate via Cu²⁺ and two PCA carboxylate groups; the chelate bond prevents rapid copper dissociation under neutral-weak acid environment, avoiding precipitation and loss of biological activity in conventional cosmetic systems.
What is the maximum legal usage percentage of Copper PCA in EU leave-on skincare per CosIng regulation?
-
EU CosIng sets upper safe limit at 1.0% w/w for leave-on cosmetic products; formulation above 1% needs finished human skin patch safety certification before mass production.
How does Copper PCA achieve dual effects of moisturization and antioxidant on skin layer?
-
Undissociated PCA ligand provides humectation via polar water-binding groups; slowly released Cu²⁺ activates cutaneous SOD enzyme to eliminate ROS free radicals, realizing two independent biochemical functions from single ingredient.
Can Copper PCA be compounded with Zinc PCA and Hyaluronic Acid in the same cosmetic formula?
-
Verified formulation test shows excellent compatibility at processing temperature below 40℃; no precipitation or chemical degradation, meanwhile generates synergistic sebum-control & barrier-repair efficacy.
What's proper storage condition to reach 24-month shelf life of bulk Copper PCA?
-
Keep package sealed with nitrogen filling, store at 10~25℃ cool dry warehouse away from sunlight and iron/copper containers; once unpacked, finish consumption within 3 months to prevent deliquescence.
