Two-Phase Makeup Remover Oil Phase Density and Interfacial Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-phase makeup removers without silicone oils and lower alkanes suffer from increased separation time, sweating effects, and haziness, which affect their ability to remove waterproof makeup effectively.
Innovation Solution
A two-phase cosmetic cleansing composition with an aqueous phase and an oil phase, where the oil phase has an interfacial tension towards water ranging from 22 to 35 mN/m and a density between 0.82 and 0.90 g/cm3, and is free from silicone oils and lower alkanes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If silicone oils and lower alkanes are used in two-phase makeup remover, then phase separation is fast and effective, but consumer acceptance decreases due to controversial ingredients
Solution Approach 1:
The patent changes the chemical composition parameters of the oil phase by specifying interfacial tension (22-35 mN/m) and density (0.82-0.90 g/cm³) ranges, replacing silicone oils and lower alkanes with alternative oils that meet these parameters, thereby maintaining fast phase separation without controversial ingredients
Solution Approach 2:
The patent creates a composite oil phase system combining multiple oil components (e.g., caprylic/capric triglyceride, isodecyl neopentanoate, cocoglycerides) in specific proportions to achieve the desired interfacial tension and density characteristics while avoiding silicone oils and lower alkanes
2Object-affected harmful factors
If silicone oils and lower alkanes are omitted from two-phase makeup remover, then consumer acceptance improves, but sweating effects and haziness increase
Solution Approach 1:
The patent precisely controls the interfacial tension parameter (22-35 mN/m) and density parameter (0.82-0.90 g/cm³) of the oil phase to prevent sweating and haziness while maintaining consumer-friendly composition without silicone oils and lower alkanes
3Object-affected harmful factors
If silicone oils and lower alkanes are removed from two-phase makeup remover, then consumer acceptance improves, but ability to remove waterproof makeup decreases
Solution Approach 1:
The patent optimizes the oil phase composition parameters (interfacial tension 22-35 mN/m, density 0.82-0.90 g/cm³) to ensure sufficient lipid solubility and cleansing effectiveness while using consumer-preferred ingredients without silicone oils and lower alkanes
