Two Phase Water-Based Make-Up Remover Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-phase liquid cleansing compositions struggle to achieve satisfactory phase separation performances while maintaining high natural content, making it challenging to develop a 'highly natural' or 'all natural' make-up removing cleanser with aesthetic appeal and effective phase separation.
Innovation Solution
A cleansing composition comprising at least two visually distinct phase layers, where one phase includes an amino-acid derived cationic surfactant and an inorganic salt, and the other phase includes a plant-derived alkane or alkylether, achieving a milky single phase upon agitation that separates into distinct phases within 24 hours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-phase cleansing compositions use synthetic ingredients like emulsifying surfactants, volatile silicone oils, and polyalkylene glycols to achieve desired aesthetic appearance and phase separation, then phase separation performance and visual appeal are improved, but skin and eye irritation increases and natural content decreases
Solution Approach 1:
The patent changes the chemical parameters by replacing synthetic surfactants and silicone oils with amino acid-derived cationic surfactants and plant-derived alkanes/alkylethers. This substitution maintains the multi-phase structure and separation performance while eliminating irritating synthetic ingredients, achieving both reliable phase separation and reduced skin/eye irritation through fundamentally different chemical composition
Solution Approach 2:
The invention creates a composite formulation combining amino acid-derived cationic surfactants with plant-derived alkanes or alkylethers in a multi-phase system. This composite approach integrates natural ingredients that work synergistically to provide effective makeup removal and aesthetic appearance without relying on synthetic irritants, thus resolving the contradiction between performance and safety
2Shape
If conventional multi-phase compositions include synthetic ingredients to achieve aesthetic appearance, then visual and tactile appeal is improved, but natural content percentage decreases
Solution Approach 1:
The patent fundamentally changes the compositional parameters by formulating with 100% natural ingredients including amino acid-derived cationic surfactants and plant-derived alkanes/alkylethers. This parameter change enables the product to achieve high aesthetic appearance through natural means while maintaining 100% natural content, eliminating the trade-off between appearance and naturalness
Solution Approach 2:
The invention extracts and eliminates all synthetic ingredients from the formulation, retaining only natural components. By removing synthetic surfactants, silicone oils, and other petrochemical-derived substances, the patent achieves both aesthetic appeal and 100% natural content, resolving the contradiction between visual appeal and natural ingredient percentage
3Stability of the object's composition
If multi-phase compositions use synthetic emulsifiers and polymers to maintain phase separation, then phase stability is improved, but sustainability profile and environmental impact worsen
Solution Approach 1:
The patent changes the material parameters by substituting synthetic emulsifiers and polymers with naturally-derived alternatives. The amino acid-derived cationic surfactants and plant-derived alkanes/alkylethers provide sufficient phase stability through their natural chemical properties, achieving both composition stability and improved environmental sustainability by eliminating persistent synthetic chemicals
Solution Approach 2:
The invention converts the potential harm of synthetic chemicals into benefit by using naturally-derived ingredients that provide equivalent or superior performance. The natural ingredients offer biodegradability and environmental compatibility while maintaining phase stability, turning the limitation of natural materials into a sustainability advantage
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 composition provides effective make-up removal, is aesthetically pleasing, and maintains a high natural content, ensuring minimal irritation to the skin and eyes while demonstrating excellent phase separation properties.
Implementation Method 1
a multi-phase liquid forms two or more visibly distinct phases. When agitated, the cleansing composition forms a visible single phase, which separates and returns to the multiple visibly distinct phases
Implementation Method 2
When agitated, the cleansing composition forms a visible single phase

AI summary
A cleansing composition includes at least two visually distinct phase layers that include a first visually distinct phase layer including at least one amino-acid derived cationic surfactant, and at least one inorganic salt, and a second visually distinct phase layer including at least one plant-derived alkane or plant-derived alkylether. The at least one cationic surfactant is an amino acid based cationic surfactant that may be selected from a derivative ethyl lauroyl arginate or a salt thereof, and ethyl cocoyl arginate or a salt thereof (PCA ethyl cocoyl arginate). The first visually distinct phase layer may be present at about 50% to about 95% and the second visually distinct phase layer may be present at about 5% to about 50%, by weight, based on the total weight of the cleansing composition.
