Solid Cosmetic Composition Using Sucrose Polyesters for Migration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lipsticks and other cosmetic products face issues with migration, affecting the sharpness of lip contours and eye make-up application, while structuring agents used to reduce migration often compromise gliding and gloss.
Innovation Solution
A solid cosmetic composition combining sucrose polyesters as lipophilic gelling agents with hydrogenated oils and non-volatile oils, along with a controlled wax content, to prevent migration without impacting gliding or gloss, ensuring a sharp, precise application and increased staying power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If structuring agents of the wax and/or filler type are used to reduce migration, then migration is reduced, but the gliding of the composition onto the lips is negatively affected and a matt effect is produced
Solution Approach 1:
The patent changes the chemical composition parameters by using specific wax types (beeswax, carnauba wax, candelilla wax) and controlling their proportions (0.1-5% each), along with specific filler types (silica, titanium dioxide) at controlled levels (0.1-5%), to achieve migration resistance while preserving gliding properties and gloss appearance
Solution Approach 2:
The patent creates a composite formulation combining multiple wax types, fillers, oils, and active ingredients in specific proportions to achieve a balanced composition that simultaneously provides migration resistance, maintains gliding, and preserves gloss without producing a matte effect
2Reliability
If structuring agents of the wax and/or filler type are used to reduce migration, then migration is reduced, but a matt effect is produced that is not desirable for lip glosses
Solution Approach 1:
The patent carefully controls the type and amount of fillers used (silica, titanium dioxide at 0.1-5%) to provide migration resistance while selecting and dosing gloss-providing ingredients (oils, waxes) to maintain the desired glossy appearance and prevent matte effect
3Ease of operation
If the composition is made to glide easily onto the lips, then gliding is improved, but migration increases affecting the sharpness of lip contours
Solution Approach 1:
The patent optimizes the balance between gliding agents (oils, butters) and structuring agents (waxes, fillers) by controlling their proportions, ensuring the composition glides smoothly during application while the structured network prevents subsequent migration that would blur lip contours
Solution Approach 2:
The composition exhibits dynamic behavior where it remains structured and firm at rest to prevent migration, but becomes softer and more pliable during application to provide smooth gliding, then sets again after application to maintain sharp contours
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 composition effectively reduces migration, maintains a glossy appearance, and provides a creamy texture with enhanced staying power, ensuring a sharp lip contour and precise application without a matte effect.
