TL;DR. This ingredient is mainly used in oral care and deodorant formulas as an odor-control and antimicrobial-support agent. It can also contribute a mild astringent feel in skin and scalp products.
What does Zinc Citrate do in a cosmetic formula?
This ingredient is mainly used in oral care and deodorant formulas as an odor-control and antimicrobial-support agent. It can also contribute a mild astringent feel in skin and scalp products.
Is Zinc Citrate clean?
It is generally well accepted in clean-beauty frameworks and is not a common restricted-list concern. The main formulation watchout is astringency or dryness at higher use levels, especially in products used on sensitive skin or mucosa.
Is Zinc Citrate sustainable?
This material combines a mined metal source with an acid component commonly made by fermentation. The acid portion is biodegradable, but the metal ion is not biodegradable and can contribute to aquatic load if released in high concentrations.
Is Zinc Citrate COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic formulations when the raw material meets the standard’s sourcing and processing requirements. Its Green Chemistry profile is mixed, with simple salt chemistry and a biodegradable acid component on the positive side, and mined, non-biodegradable metal content as the compromise.
How does Zinc Citrate work chemically?
This compound is a sparingly soluble divalent metal it salt that can release metal ions gradually and interact with odor-related sulfur compounds. In oral care, typical use is often around 0.5% to 2%, with performance depending on dispersion, water phase chemistry, and compatibility with anionic surfactants and chelators.
