What Is Zinc Lactate?
Zinc lactate is a salt formed from zinc and lactic acid. It appears in skincare and personal care products primarily for its deodorant function, where it works to reduce odour-causing bacteria and moisture on the skin surface.
This ingredient is relatively uncommon in skincare formulations, appearing in fewer than 1 in 1,000 products. Its role is distinct from other zinc compounds used in skincare, which are typically chosen for their antioxidant or soothing properties.
How It Works
Zinc lactate functions as a deodorant by inhibiting the growth of odour-producing bacteria on the skin and by helping to regulate moisture. The zinc component carries antimicrobial properties, whilst the lactate carrier may improve the solubility and bioavailability of the zinc.
Unlike antiperspirants, zinc lactate does not block sweat production; instead, it addresses odour at the source by reducing bacterial proliferation in the sweat environment.
Clinical Evidence & References
Research suggests that zinc lactate demonstrates good solubility and bioavailability when formulated correctly, which supports its use in personal care applications where these properties are advantageous. Studies comparing different zinc sources indicate that lactate-bound zinc may offer improved availability compared to other zinc formulations.
However, specific clinical evidence for zinc lactate's effectiveness as a deodorant agent in skincare products is limited. Most published research focuses on zinc's general antimicrobial properties rather than this particular salt form in cosmetic applications.
How to Use
Zinc lactate is typically incorporated into deodorant or antiperspirant formulations rather than used as a standalone skincare treatment. Follow product instructions for application frequency, which is usually daily. If combining with other active ingredients, apply as directed by the product label to avoid over-layering.
