Oil Cleansing Composition Transparency and Smoothness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oil-based cleansing compositions face issues with transparency loss and reduced cleansing performance when water is interfused, leading to white turbidity and decreased smoothness during use, limiting their application in wet conditions.
Innovation Solution
An oil-based cleansing composition comprising a nonionic surfactant with a HLB of 6 to 14, an oil component with 80% hydrocarbon or ester oil and 1-10% silicone oil, and a liquid fatty acid or alcohol, formulated to form a micellar aqueous solution or bicontinuous microemulsion phase when mixed with water, maintaining transparency and smoothness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water is interfused into the oil-based cleansing composition, then the cleansing performance is improved, but the transparency decreases and white turbidity occurs
Solution Approach 1:
The patent changes the HLB parameter of the nonionic surfactant to a specific range (6-14) and controls the water content parameter (less than 5% by mass) to maintain the optimal balance between water solubility and oil solubility, preventing white turbidity while enabling effective cleansing performance even when water is interfused
2Reliability
If water is interfused into the oil-based cleansing composition, then the cleansing performance is improved, but the smoothness of massaging is reduced
Solution Approach 1:
The patent optimizes the HLB parameter of the nonionic surfactant (6-14) and controls the water content (less than 5% by mass) to maintain optimal balance between water and oil phases, ensuring that the composition remains smooth and pleasant during massaging while achieving effective cleansing performance when water is interfused
3Quantity of substance
If the solubilizing power is increased to accommodate more water, then the transparency is maintained, but the microstructure limitation is reached
Solution Approach 1:
The patent optimizes the HLB parameter of the nonionic surfactant to a specific range (6-14) that provides maximum solubilizing power for water within the oil phase, allowing the composition to accommodate water content while maintaining a stable microstructure and transparency

Function Achieved in This Case
The composition achieves high cleansing performance with minimal eye irritation, no white turbidity, and maintained smoothness even when water is interfused, ensuring effective use on wet skin without reduced performance.
Implementation Method 1
the surfactant forms aggregates in the oil component by arranging hydrophilic groups along the inner side. Water is solubilized in the core of the micelle where the hydrophilic groups gather
Implementation Method 2
Water is solubilized in the core of the micelle where the hydrophilic groups gather, and the prepared 1-phase solution is completely transparent
Implementation Method 3
a micellar aqueous solution phase or a bicontinuous microemulsion phase is formed when said oil-based cleansing composition and water are mixed in the ratio of 4:6
