Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions thickened with hydrophobically modified ethoxylated urethane face challenges in maintaining high-temperature stability and unique jiggling texture when exposed to salt concentration, pH variations, and high temperatures, often requiring additional thickeners that can compromise the jiggling feel.
Innovation Solution
Incorporating hydrophobically modified ethoxylated urethane into an oil-in-water emulsified product with oil droplets of 150 nm or less, achieving a synergistic thickening effect without additional thickeners, which maintains viscosity stability and the jiggling texture at high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydrophobically modified ethoxylated urethane is used as a thickener in cosmetic compositions, then the composition provides a unique jiggling touch and excellent viscosity stabilizing property, but the viscosity reduces when stored at high temperature (e.g., 50°C)
Solution Approach 1:
The patent combines hydrophobically modified ethoxylated urethane with fine oil-in-water emulsified products to create a composite thickening system. This composite approach allows the hydrophobically modified polymer to provide the characteristic jiggling touch while the fine emulsion structure contributes to high-temperature viscosity stability, resolving the contradiction between maintaining unique texture and ensuring thermal stability.
2Stability of the object's composition
If water-soluble polymers or microgels are added to prevent viscosity reduction at high temperatures, then high-temperature stability is improved, but the jiggling unique feeling is removed
Solution Approach 1:
The patent changes the physical parameters of the emulsion system by controlling oil droplet size to 150 nm or less. This parameter change enables the system to achieve high-temperature stability through the fine emulsion structure itself, rather than relying on additional thickeners that would compromise the jiggling sensation. The parameter change in droplet size allows both stability and texture to coexist.
3Stability of the object's composition
If additional thickeners are co-blended to improve high-temperature stability, then viscosity stability is improved, but the mixing removes the jiggling unique feeling originally possessed by the composition
Solution Approach 1:
The fine oil-in-water emulsified product acts as an intermediary system that mediates between the thickening function and the texture requirement. Instead of directly adding more thickeners that would disrupt the jiggling feel, the emulsion system provides a subtle structuring effect that enhances high-temperature stability while preserving the characteristic texture provided by the hydrophobically modified ethoxylated urethane.
