COBALT DNA.

Avoid / ANTIOXIDANT, HUMECTANT, SKIN CONDITIONING, SKIN PROTECTING, UV ABSORBER, VISCOSITY CONTROLLING

Cobalt DNA is posited as a multi-functional ingredient in cosmetic formulations, offering benefits such as humectancy, antioxidant activity, and UV absorption. It also serves as a skin conditioner, skin protecting agent, and viscosity controller, with potential applications in modifying skin and hair surfaces.

Antioxidant Humectant Skin Conditioning Skin Protecting UV Absorber Viscosity Controlling

Science

Mechanism of Action

This ingredient is theorized to function by attracting and retaining moisture as a humectant, neutralizing free radicals through its antioxidant properties, and absorbing harmful UV radiation to offer a degree of photoprotection. It further conditions the skin and contributes to the rheological properties of formulations by controlling viscosity.

Stability

Optimal stability for general cosmetic application is indicated within a pH range of 4.0 to 6.5. However, in specific scientific contexts for 'Cobalt DNA nanoflower' formation, DNA incorporation was most efficient at pH 7.0–7.5 (using Ф29 DNA polymerase) and pH 7.0–8.0 (using Bst DNA polymerase). Dithiothreitol (DTT) is known to be incompatible with cobalt chloride, a precursor, leading to immediate precipitation.

Our Assessment

Verdict

Avoid

Due to cobalt's established status as a potent skin allergen and the ingredient's 'not reviewed' CIR status, Cobalt DNA presents a high risk for allergic contact dermatitis, rendering it unsuitable for precision skincare formulations.
