Alchemy 21/12 Files Patent for AHK-Cu Scalp Technology

Alchemy 21/12, an independent skincare company, has announced that its AHK-Cu scalp technology is now patent-pending. The company filed a U.S. provisional patent application on September 26, 2026, with the application number 64/163,219. This application covers a controlled ligand architecture for AHK-Cu topical scalp compositions.

AHK-Cu, also known as Copper Tripeptide-3, is a naturally derived copper-binding tripeptide that has been studied for its relationship to cellular signaling and processes relevant to hair and skin biology. Alchemy 21/12’s patent application focuses on the chemical environment surrounding the copper-peptide complex and the controlled use of free histidine within that architecture.

Founder Jen Valenti sees the filing as a significant step in combining advances in chemistry with the signaling systems that already exist within human biology.

The patent-pending technology grew from development work surrounding Alchemy 21/12’s AHK Peptide Hair + Scalp Serum, a topical scalp formulation built around AHK-Cu and a complementary peptide system. The serum was developed as a non-drug approach to scalp care, with an emphasis on creating an environment that supports the biological processes associated with healthy-looking hair and scalp function.

Alchemy 21/12’s research and development philosophy emphasizes understanding the chemistry and questioning the assumptions around how bioactive ingredients are used.

This filing marks the first patent application for Alchemy 21/12 and expands the company’s growing research focus on peptide signaling, copper-peptide chemistry, and biologically informed formulation design. The company continues to develop barrier-first, retinoid-free formulations that combine modern cosmetic chemistry with research into peptide signaling, skin biology, cellular communication, and formulation architecture.

This approach aims to bridge advanced chemistry with the body’s own signaling systems, providing a more holistic and biologically informed approach to scalp care.

Alchemy 21/12’s philosophy of combining chemistry with biology is rooted in a broader approach to formulation.

The company’s focus on peptide signaling and copper-peptide chemistry reflects a commitment to innovation and scientific rigor. By exploring the complex interactions between bioactive ingredients and the body’s natural signaling systems, Alchemy 21/12 aims to develop more effective and biologically informed skincare and scalp care products. This approach not only enhances the efficacy of the formulations but also aligns with a growing trend in the industry towards more natural and biologically informed solutions.

This filing is a significant milestone for Alchemy 21/12, marking the beginning of a new chapter in its research and development efforts. As the company continues to explore the potential of AHK-Cu and other bioactive ingredients, it aims to push the boundaries of what is possible in skincare and scalp care.
