Science
Mechanism of Action
The specific mechanism by which POLYESTER-2 may interact with the skin or contribute to cosmetic efficacy is currently undefined due to a lack of available research.

Stability
Specific optimal pH ranges and comprehensive stability notes for POLYESTER-2 are currently unknown. General polyesters typically demonstrate good resistance to both acidic and alkaline conditions, though extreme pH levels can induce degradation. Studies on polyester surfaces indicate potential ionization around pH 6 and a plateau in alkaline regions. While general polyesters like PET are practically insoluble in water, some derivatives may exhibit enhanced solubility in specific organic solvents.
Safety
Safety Profile
Formal safety assessments for POLYESTER-2 specifically as a cosmetic ingredient by regulatory bodies such as CIR, SCCS, or FDA are not available. While certain general polyester materials possess FDA approval for non-cosmetic applications like food contact, this does not directly pertain to POLYESTER-2 in skincare. The CIR has evaluated other polyester derivatives (e.g., Polyester-8) and polysilicones, but not POLYESTER-2. General observations concerning polyester in fabrics suggest that any skin irritation is frequently attributable to dyes, resins, or finishing agents, rather than the polyester fiber itself.
