Mascara Primer and Lengthening Formulation for Eyelash Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mascaras lack staying power on eyelashes when subjected to external forces or water, often causing damage upon removal and failing to provide desired thickening or lengthening effects.
Innovation Solution
A set of mascara formulations, including a primer and lengthening mascaras, utilizing specific combinations of polymers, synthetic fibers, natural film formers, and waxes to enhance staying power, ease of application, and removability, with the primer drying quickly to create a base for subsequent mascara application and the lengthening mascara using synthetic fibers to build along the hair shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mascara formulations are used to increase staying power and water-resistance, then the mascara becomes difficult to remove and damages eyelashes, but if stronger bonding agents are used to achieve lengthening and thickening effects, then the mascara becomes more difficult to remove and causes damage
Solution Approach 1:
The mascara system is divided into two separate products: a primer formulation and a mascara formulation. The primer is applied first and allows the mascara to be applied over it, creating a layered structure where each product has optimized properties for its specific function without compromising the other.
Solution Approach 2:
The primer formulation acts as an intermediary layer between the eyelash and the mascara. It provides a bonding base that enhances mascara adhesion and staying power while maintaining ease of removal and preventing damage to the eyelash structure.
2Quantity of substance
If thicker and more voluminous mascara formulations are used to achieve desired thickening effect, then the mascara becomes more difficult to remove and damages eyelashes, but if stronger film formers are used to enhance staying power, then the mascara becomes more difficult to remove
Solution Approach 1:
The system separates volume enhancement (achieved through fiber content in the mascara) from adhesion enhancement (achieved through the primer), allowing each component to be optimized independently for its specific function without compromising ease of removal.
Solution Approach 2:
The primer formulation uses specific polymer parameters (polyquaternium-69 at 1-3% by weight) to control film formation and adhesion properties, creating a bond that is strong enough to hold mascara but weak enough to allow easy removal without damage.
3Productivity
If faster drying primer formulations are used to improve application efficiency, then the primer dries quickly allowing second mascara application, but the formulation must still maintain ease of removability and not damage eyelashes
Solution Approach 1:
The primer formulation uses specific polymer parameters (polyquaternium-69 at 1-3% by weight) to control film formation and adhesion properties, creating a bond that is strong enough to hold mascara but weak enough to allow easy removal without damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The formulations achieve significant lengthening and thickening effects while being easy to remove without damaging eyelashes, with increased wearability and water-resistance, allowing for up to 2-5 times volume increase and lengthening of eyelashes.
Implementation Method 1
the primer formulation can include an aqueous base and 1 to 3% by weight of a polymer film former, wherein the aqueous base comprises 85 to 95% by weight of water... the composition is capable of drying within 30 seconds or within 60 seconds after application to eye lashes
Implementation Method 2
1 to 3% by weight of a polymer film former... the polymer film former is polyquaternium-69
Implementation Method 3
This lengthening process is achieved by using a combination of synthetic fibers which build along the hair shaft in combination with polymeric and natural film formers
Implementation Method 4
the primer formulation... creates the desired staying power or substantivity for the second mascara formulation
