Performance & Formulation Insights for SanFill TA
Talc-Comparable Performance Profile
SanFill TA closely matches conventional talc (SanTalc H108) across key performance metrics. Oil absorption measured at 66.40 g/100g, comparable to talc’s 64.00 g/100g, while pH (5–10) and low loss on drying (LoD <1%) fall within a similar functional range, supporting drop-in substitution in existing formulations.
Drop Resistance & Contact Angle
In 5-inch and 10-inch, 5-drop impact testing, SanFill TA showed drop resistance behavior comparable to SanTalc H108. Contact angle measurements over a 20-minute period tracked closely with conventional talc, indicating similar wetting and surface interaction characteristics important for pressed powder cohesion and skin-feel.
Consumer-Validated Sensory Performance
In a 17-panelist consumer evaluation of pressed eyeshadow formulations, the majority reported no noticeable differences between SanFill TA and SanTalc H108: 76% saw no difference in color, 59% in application, 53% in texture, and 59% in pickup. Among panelists who did note a difference in application and pickup, all preferred the SanFill TA formulation; among those noting a texture difference, half found the SanFill TA version felt softer.
Key Formulation Benefits
- Talc-Equivalent Oil Absorption: Matches conventional talc’s oil absorption profile (66.40 vs. 64.00 g/100g) for consistent formulation behavior.
- Comparable Drop & Impact Resistance: Performs similarly to talc under 5-inch and 10-inch drop testing, supporting cake integrity in pressed formats.
- Matching Wetting Behavior: Contact angle performance tracks closely with talc over time, indicating similar surface wetting characteristics.
- Consumer-Preferred Sensory Feel: Independent panel testing found no adverse sensory trade-offs, with a preference toward SanFill TA where differences were noted.
