Eyelash Coating Composition with Low Tg Latex for False Lash Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyelash and eyebrow coating compositions lack effective adhesion properties to securely attach false or artificial eyelashes and eyebrows to natural ones, requiring complex and cumbersome application processes.
Innovation Solution
A water-based coating composition containing fibers and a latex film-forming agent with a low glass transition temperature, which provides sufficient tack and quick-drying properties to facilitate the adhesion of false eyelashes and eyebrows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adhesives or glues are used to attach false eyelashes, then adhesion can be achieved, but the application process becomes complex and cumbersome requiring multiple steps
Solution Approach 1:
The patent combines the adhesive function with the mascara function into a single integrated composition. The coating composition includes both bonding agents (such as cyanoacrylate or polyvinyl alcohol) and mascara ingredients (wax, fiber, pigment) in one formulation, allowing users to apply false eyelashes and color their natural lashes simultaneously in a single step, eliminating the need for separate adhesive and mascara applications
Solution Approach 2:
The coating composition is designed to perform multiple functions: it acts as an adhesive to bond false eyelashes to natural lashes, provides mascara functionality to color and condition natural lashes, and offers easy removal properties. This multi-functional formulation replaces the need for separate adhesive, mascara, and conditioning products
2Duration of action of stationary object
If water-resistant mascaras are used, then long-wearing properties are improved, but ease of removal deteriorates
Solution Approach 1:
The patent modifies the formulation parameters by incorporating specific bonding agents (cyanoacrylate or polyvinyl alcohol) that provide controlled adhesion. These agents create a bond that is strong enough to maintain false eyelashes throughout the day but can be easily broken down by simple wiping or dissolving action, achieving both long-wearing and easy-removal properties through chemical parameter optimization
3Reliability
If separate application of liquid adhesive and fiber filaments is used, then adhesion can be achieved, but the process becomes time-consuming
Solution Approach 1:
The patent merges the application of adhesive and fiber filaments into a single simultaneous step. The coating composition contains both the bonding agent and fiber filaments mixed together, allowing the user to apply both components at once rather than sequentially. This maintains reliable adhesion while significantly reducing application time by eliminating the need for separate adhesive application and drying steps

Function Achieved in This Case
The composition effectively adheres false eyelashes and eyebrows to natural ones, simplifying the application process and providing a durable, long-lasting attachment.
Implementation Method 1
at least one latex film-forming agent having a low glass transition temperature (Tg)
Implementation Method 2
allowing the eyelash and/or eyebrow coating composition to dry
