Bio-based tunable adhesive for artificial nail applications
Discover a sustainable, bio-based adhesive system using zein for durable and safe artificial nail applications. This adhesive offers strong bonding without UV curing and easy removal with ethanol, addressing industry challenges like poor adhesion and painful removal.
Overview
Introducing a revolutionary bio-based adhesive system designed for artificial nail applications, addressing key industry challenges such as poor adhesion and painful removal. Based on zein—a plant protein—this adhesive forms a tunable film that bonds strongly to nails, including opaque ones, without the need for UV curing. It provides water resistance and can be easily removed using a standard ethanol solution, ensuring no damage to natural nails. The adhesive strength is adjustable, offering long-lasting wear without discomfort during removal. Safe for use and compatible with existing manufacturing processes, this adhesive promises a user-friendly and sustainable alternative for artificial nail wear.
Technical specifications
- Base Component: Zein, a plant protein known for forming cohesive, hydrophobic films.
- Adhesion Strength: Tunable to prevent pop-off and ensure easy removal, targeting a pull-off strength of 1-2 MPa.
- Durability: 7+ days of wear with potential for 14-day durability under dry and wet conditions.
- Removal Method: Easily dissolves in ethanol, preventing damage to natural nails.
- Application Time: Full adhesion achieved within 5-10 minutes after application.
- Scalability: Uses safe, inexpensive ingredients and eliminates the need for UV light or harsh solvents.
Technology readiness level
This adhesive system is currently at Technology Readiness Level 3, having undergone early-stage validation. Future steps include formulation optimization, real nail testing, prototype development, and optional shelf-life assessments to further validate safety, performance, and consumer expectations.
