Introduction

Zinc is an essential trace element with a multitude of critical physiological functions. It is a constituent of over 200 enzymes that play pivotal roles in the metabolism of proteins, nucleic acids, lipids, and carbohydrates. Zinc is also integral to DNA and RNA synthesis, making it fundamental for cell division, proliferation, and differentiation—the very cornerstones of growth and development.

In personal care, zinc's benefits are widely recognized. It promotes wound healing, offers anti-inflammatory and antibacterial properties, acts as an antioxidant, controls sebum production, and supports collagen synthesis. However, conventional zinc ingredients, primarily inorganic and water-soluble organic zinc salts, present significant challenges for formulators. Their use is often limited by regulatory caps on free zinc content (e.g., a 1% limit) and can lead to formulation instability and potential skin irritation.

Our 4th generation chelated zinc is engineered for superior stability and a controlled, sustained release, overcoming the limitations of traditional zinc salts.

A Breakthrough in Formulation Science

We are proud to introduce the world's first independently developed "chelated" zinc—a fourth-generation, protein-like zinc compound. This innovation directly addresses the core issues associated with free zinc ions in cosmetic formulas, such as high ionicity, precipitation, poor compatibility, and skin irritation.

This novel compound is the culmination of over 20 years of our research team's expertise in aspartic proteins. The groundbreaking structure is a new chemical entity formed through chelation, where coordinate bonds are established between zinc and the carboxyl oxygen and amide nitrogen atoms in the side chains of polyaspartic acid. This unique structure ensures that zinc is delivered gently and effectively. This new raw material has completed its official notification process and is currently patent-pending.

"Our novel chelated structure solves the long-standing challenge of zinc instability and irritation by delivering its benefits through a sophisticated slow-release mechanism, enhancing both the safety and efficacy of cosmetic formulations."

The primary function of this ingredient is superior oil control. Its core advantage lies in the sustained release of zinc ions. This mechanism not only mitigates safety concerns but also significantly prolongs the active time of zinc at the target site. In both in vitro and in vivo studies, our chelated zinc has demonstrated a remarkably slower release profile compared to common water-soluble zinc salts. This data not only confirms its chelated nature but also validates its enhanced safety and prolonged efficacy. The ingredient has successfully passed a battery of tests, including comprehensive oil-control efficacy trials and independent safety assessments.

Conclusion

This advancement is more than just a new ingredient; it's a testament to the power of scientific innovation in cosmetics. We believe this fourth-generation chelated zinc provides a powerful new tool for formulators, enabling the creation of safer, more stable, and highly effective skincare and hair care products. We cordially invite brands and formulators to experience its practical efficacy firsthand. Request a sample today and join us in shaping the future of innovative cosmetic ingredients.
