CRYPTOCOCCUS/FILOBASIDIELLA/GRAPE EXTRACT FERMENT LEES.

Avoid CAS - / ANTIMICROBIAL

This ingredient comprises the fermentation lees from grape extract, involving microorganisms from the genera Cryptococcus and Filobasidiella. While generic ferment lees typically yield beneficial biomolecules, precise information on this specific combination for cosmetic application is currently unavailable.

Science

The proposed mechanism, extrapolated from general wine lees, involves the autolysis of yeast cells, which liberates a rich array of cellular components. These include peptides, amino acids, nucleotides, fatty acids, and mannoproteins, recognized for their potential antioxidant and skin-conditioning properties. However, the specific biological activity and precise mechanism of action on the skin for CRYPTOCOCCUS/FILOBASIDIELLA/GRAPE EXTRACT FERMENT LEES have not been specifically studied or characterized.

Stability

Specific pH range and stability data for this exact ingredient are not available. However, components typical of yeast-derived extracts, such as peptides and amino acids, often exhibit stability across a broad pH range, potentially from 4.0 to 10.0. The overall extract contains both water-soluble compounds (e.g., polysaccharides) and potentially oil-soluble compounds (e.g., lipids).


Safety

CIR Status
Not reviewed
Sensitization risk Unknown

The inclusion of 'Cryptococcus' and 'Filobasidiella' in the ingredient name raises significant safety concerns. Research indicates that species such as *Cryptococcus neoformans* are recognized human fungal pathogens capable of causing serious infections. No specific safety assessments for this combined ingredient have been conducted by cosmetic regulatory bodies like CIR, SCCS, or FDA. While general grape and yeast-derived ingredients have typically received favorable safety assessments, these do not extend to this specific combination, particularly given the association with potentially pathogenic organisms. Without explicit verification of the specific non-pathogenic strains used and robust processing methods to ensure complete safety, this ingredient carries a high degree of unknown risk for cosmetic application.

Our Assessment

Avoid

Due to the explicit association of Cryptococcus and Filobasidiella with human pathogens and the complete lack of specific safety and efficacy data for this ingredient in cosmetics, its use is currently not recommended.
