Cosmetic Cleansing Composition for High-Oil Foam and Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic cleansing compositions struggle to incorporate high amounts of vegetable oils for conditioning while maintaining satisfactory foaming properties, viscosity, and transparency, leading to potential damage to keratinous materials and aesthetic issues.
Innovation Solution
A personal care composition comprising a specific combination of taurate and sultaine surfactants with a non-ionic solubilizer, such as a mono- or poly-alkyl or alkenyl ester of an alkoxylated fatty acid, allows for high vegetable oil content without negatively impacting viscosity, foaming, and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high amounts of vegetable oils are incorporated in cleansing personal care compositions, then conditioning properties are improved, but foaming properties and transparency are negatively impacted
Solution Approach 1:
The patent introduces a specific non-ionic surfactant as an intermediary substance that enables the solubilization of high amounts of vegetable oils (at least 0.3 pbw) without adversely affecting the foaming properties, viscosity, or transparency of the cleansing composition. This intermediary component acts as a bridge between the oil phase and aqueous phase, allowing the system to maintain both conditioning benefits and aesthetic properties.
Solution Approach 2:
The patent modifies the chemical composition parameters by incorporating a specific non-ionic surfactant with defined molecular structure and properties. This parameter change enables the system to solubilize high concentrations of vegetable oils while maintaining transparency and foaming characteristics, effectively changing the physical-chemical parameters of the overall formulation.
2Reliability
If high amounts of vegetable oils are incorporated in cleansing personal care compositions, then conditioning properties are improved, but viscosity is negatively impacted
Solution Approach 1:
The non-ionic surfactant serves as a mediator that controls the interaction between vegetable oils and the aqueous phase, preventing excessive viscosity increase. By forming micellar structures, the surfactant allows high oil content while maintaining fluidity and acceptable viscosity characteristics for a cleansing composition.
Solution Approach 2:
The introduction of the non-ionic surfactant changes the rheological parameters of the formulation. The surfactant's molecular structure and concentration are optimized to maintain the composition within acceptable viscosity ranges despite high vegetable oil content, effectively controlling the flow and consistency properties.
3Reliability
If high amounts of vegetable oils are incorporated in cleansing personal care compositions, then conditioning properties are improved, but greasiness increases
Solution Approach 1:
The non-ionic surfactant acts as an intermediary that prevents the direct contact and accumulation of vegetable oils on the skin surface. By forming stable micellar structures in the aqueous phase, the surfactant allows the oils to be carried and distributed uniformly without creating a greasy film, thus maintaining conditioning benefits while avoiding excessive greasiness.
