CUPRIAVIDUS METALLIDURANS FERMENT EXTRACT FILTRATE.

Insufficient Data / SKIN CONDITIONING - EMOLLIENT

CUPRIAVIDUS METALLIDURANS FERMENT EXTRACT FILTRATE is a derivative obtained from the fermentation process of the *Cupriavidus metallidurans* bacterium. While the source bacterium is notably resistant to heavy metals, public domain research currently provides very limited specific information regarding this ingredient's cosmetic efficacy and safety on human skin.

Summary

emollient

Science

Mechanism of Action

The *Cupriavidus metallidurans* bacterium exhibits remarkable capabilities in detoxifying various heavy metals, including the biotransformation of toxic gold ions into elemental gold, through intricate cellular mechanisms. However, the specific mechanism of action by which its ferment extract filtrate confers benefits to human skin remains largely undocumented in publicly accessible literature. The sole attributed cosmetic function for the filtrate is as an emollient, suggesting a potential role in surface hydration and conditioning.

Dusting Analysis

Not commonly dusted

Given the designation of CUPRIAVIDUS METALLIDURANS FERMENT EXTRACT FILTRATE as a 'new ingredient' with 'no known benefits' beyond emollient function by recognized industry resources, it is not currently identified as an ingredient commonly 'dusted' in formulations. The lack of specific efficacy data precludes defining a dusting threshold or red-flag percentage.

Stability

Specific information regarding the optimal pH range for the stability of the ferment extract filtrate as a cosmetic ingredient is currently unavailable. Studies on the live *Cupriavidus metallidurans* bacterium indicate robust activity across a pH range of 5.0 to 8.0, with peak performance around pH 7.0 for heavy metal accumulation. However, this metabolic data for the organism may not directly translate to the stability requirements of its isolated ferment filtrate.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

CUPRIAVIDUS METALLIDURANS FERMENT EXTRACT FILTRATE has not undergone specific safety assessments by major cosmetic regulatory bodies such as the Cosmetic Ingredient Review (CIR), the Scientific Committee on Consumer Safety (SCCS), or the FDA. While CIR has evaluated general categories of yeast and Lactobacillus derived ferment ingredients, this particular ferment extract filtrate lacks dedicated safety profiles in public records, resulting in an unknown sensitization risk.
