O17. The development of 'time release' nail enamels

Area of Science:

• Polymer Science
• Materials Science
• Cosmetic Science

Background:

• Plasticizers significantly influence nail enamel film properties.
• The phenomenon of 'internal flow' during film formation impacts durability.
• Optimizing the balance of resins, plasticizers, polymers, and solvents is key.

Purpose of the Study:

• To investigate the role of plasticizers in nail enamel film formation.
• To understand and control the 'internal flow' phenomenon for enhanced wear.
• To develop a nail enamel formulation with improved crack and scuff resistance.

Main Methods:

• Regulating the interactions and levels of film constituents to control 'time release' of solvents and plasticizers.
• Utilizing alkyl adipates as plasticizers to manage internal flow.
• Incorporating adhesion promoters for substrate compatibility.

Main Results:

• Extended 'internal flow' time correlates with improved nail enamel wear.
• Alkyl adipates effectively control internal flow via time release.
• The optimized formulation demonstrates superior crack and scuff resistance.
• The developed film adheres well and performs consistently on human nails.

Conclusions:

• Controlling the 'internal flow' phenomenon is crucial for enhancing nail enamel performance.
• Optimized time release of plasticizers and solvents leads to superior film characteristics.
• The study successfully optimized conventional quick-dry nail enamels for consumer expectations.
