Foamable cleansing compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oil and emulsifier-based cleansing formulations fail to produce satisfactory quality foam when used with inverted foam dispensers, despite working with conventional upright dispensers, until the discovery of fatty acid glucamides as additives that resolve this issue.
Innovation Solution
Incorporating fatty acid glucamides, such as cocoyl methyl glucamide, into the formulations allows for the production of foams that can be used in both upright and inverted foam dispensers, combining with other surfactants and oils to enhance cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional washing additives are added to oil-based formulations, then foam production is improved, but compatibility with inverted dispensers deteriorates
Solution Approach 1:
The patent achieves universality by developing a formulation system that works across multiple dispenser types (both upright and inverted). The specific combination of fatty acid glucamides with oils and emulsifiers creates a versatile composition that maintains foam production capability while adapting to the unique requirements of inverted dispensers, thus resolving the contradiction between foam production and dispenser compatibility.
Solution Approach 2:
The patent resolves the compatibility issue by changing the surfactant system parameters through the introduction of fatty acid glucamides. This compositional modification alters the formulation's physical and chemical properties to ensure proper operation in inverted dispensers while maintaining effective foam generation, addressing both aspects of the contradiction.
2Area of moving object
If foam is used instead of liquid, then surface area and spreading ease are improved, but cleaning efficiency deteriorates
Solution Approach 1:
The patent applies composite materials by formulating a foam system that combines fatty acid glucamides with oils and conventional surfactants. This composite composition maintains the high surface area advantage of foams while restoring cleaning efficiency through the synergistic interaction of multiple surfactant components, resolving the contradiction between surface area and cleaning performance.
Solution Approach 2:
The patent resolves this contradiction by changing the chemical composition parameters of the foam formulation. The specific inclusion of fatty acid glucamides at optimized concentrations modifies the foam's cleaning properties, enabling it to maintain both high surface area coverage and effective cleaning performance that matches or exceeds liquid formulations.
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 use of fatty acid glucamides in oil-based cleansing compositions results in foams with improved cleaning efficiency, comparable to or exceeding that of liquid cleansers, while reducing the amount of initial liquid required, and ensuring effective operation in both upright and inverted dispensing systems.
Implementation Method 1
0.5 to 12% by weight of at least one fatty acid glucamide
Implementation Method 2
A pumping unit is attached to the top of the bottle and comprises a dispenser which is pumped downwards towards the bottle and forces air through the liquid to cause foam to be dispensed
