Science
Mechanism of Action
This copolymer utilizes a bio-based backbone of succinic and citric acids to establish a robust, cohesive structure. Upon application, it forms a flexible, hydrophobic barrier where the caproyl component acts as an internal plasticizer, ensuring the film remains pliable and water-resistant rather than becoming brittle or prone to cracking.

Key findings
- 01 Concentrations between 2-10% in nail lacquers demonstrate improved adhesion and wear-time extension up to 7 days.
- 02 Usage at 0.5-5% in pressed powders significantly increases mechanical stability, reducing the occurrence of product breakage and 'dusting' during use.

Dusting Analysis
This ingredient is typically utilized for its functional binding and film-forming properties; use below 0.5% in powders likely yields no measurable structural benefit, suggesting a label-only inclusion.
The Formula
Formulation
Stability
Exhibits peak stability in anhydrous environments. While stable in emulsions within physiological pH ranges, it is susceptible to hydrolysis in environments below pH 3 or above pH 8.
Synergies
- Anhydrous solvents
- Pigment dispersions
- Non-polar emollients
Conflicts
- Purely aqueous systems without emulsification
- Cationic surfactants
- Strong oxidizers
Safety
Safety Profile
Compliant with EU Regulation (EC) No 1223/2009. Due to its high molecular weight, dermal penetration is extremely unlikely, making it a safe choice for topical applications.
