Silicone Composition Reduces Rinsing Water in Cosmetic Foams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions face challenges in efficiently rinsing off lather without excessive water usage, leading to longer rinsing times and potential loss of constituents.
Innovation Solution
Incorporating a silicone composition with a hydrophobic organopolysiloxane fluid having a surface tension of 18 to 40 mN/m and a finely divided solid hydrophobic filler, which reduces water required for rinsing and maintains lather texture in foamable compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional cosmetic compositions are used, then lather can be formed, but excessive water is required for rinsing and rinsing time increases
Solution Approach 1:
The patent applies parameter changes by modifying the surface tension of the cosmetic composition through the addition of silicone compounds with specific surface tension values (15-40 mN/m). This parameter change enables the lather to be rinsed off more easily with less water, directly resolving the contradiction between water usage and rinsing time
Solution Approach 2:
The patent uses composite materials by combining silicone compounds (with specific surface tension properties) with surfactants and other cosmetic ingredients. This composite approach creates a formulation that maintains effective lather formation while significantly reducing the water required for rinsing, addressing both water usage and time concerns
2Quantity of substance
If silicone composition with surface tension of 18 to 40 mN/m is added, then water usage for rinsing is reduced, but composition complexity increases
Solution Approach 1:
The silicone composition serves multiple functions simultaneously: it acts as a surfactant booster for lather formation, a rinse aid for easy water removal, and a conditioning agent for hair softness. This multi-functionality reduces the need for separate additives, thereby limiting the increase in composition complexity while achieving significant water usage reduction
