Multi-phase makeup remover with Hildebrand solubility parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-phase liquid cleansing compositions for makeup removal often contain irritating synthetic ingredients and fail to achieve satisfactory phase separation and high natural content, making it challenging to create a 'highly natural' or 'all natural' product that is aesthetically pleasing and effective.
Innovation Solution
A multi-phase cleansing composition with distinct phase layers, including a cationic surfactant and inorganic salt, utilizing solvents with specific Hildebrand solubility parameters, which forms a milky single phase upon agitation and separates into distinct phases, avoiding harsh ingredients and achieving effective makeup removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multi-phase liquid cleansing compositions include emulsifying surfactants and polymers, and volatile silicone oils to provide excellent aesthetic appearance and visual appeal, then the product becomes irritating to skin or eyes
Solution Approach 1:
The invention extracts and removes harmful synthetic ingredients (emulsifying surfactants, polymers, volatile silicone oils) from the formulation while retaining the desired multi-phase visual appeal through natural ingredient combinations that separate into distinct phases when left standing
Solution Approach 2:
The invention changes the chemical composition parameters by substituting synthetic ingredients with natural alternatives, specifically using natural oils and plant-based components that provide phase separation and visual appeal without causing skin or eye irritation
2Illumination intensity
If multi-phase liquid cleansing compositions use synthetic ingredients to achieve desired aesthetic benefits, then the product fails to achieve high natural content
Solution Approach 1:
The invention changes the origin parameter of ingredients from synthetic to natural, achieving over 99% natural content while maintaining aesthetic appeal through the visual separation of natural oil phases and water phases that create an attractive multi-layer appearance
Solution Approach 2:
The invention uses composite natural materials combining multiple natural oils and plant-based ingredients that work together to provide both aesthetic multi-phase appearance and high natural content certification compliance
3Quantity of substance
If multi-phase liquid cleansing compositions are formulated with natural ingredients, then phase separation performance becomes unsatisfactory
Solution Approach 1:
The invention adjusts the physical parameters of natural ingredients, specifically selecting oils with appropriate viscosity, density, and polarity to ensure sharp phase separation and stable multi-phase structure when left standing, while maintaining natural composition
Solution Approach 2:
The invention combines multiple natural ingredients with complementary properties - using natural emollients, plant oils, and water-soluble components in specific ratios that promote efficient phase separation and stable stratification into distinct visual layers
4Quantity of substance
If multi-phase liquid cleansing compositions aim to be highly natural, then the ability to remove long-wear makeup effectively is compromised
Solution Approach 1:
The invention segments the formulation into multiple functional phases - an oil phase for dissolving makeup, a water phase for cleansing, and natural surfactant components that work synergistically to effectively remove long-wear makeup while maintaining high natural content
Solution Approach 2:
The invention creates a composite natural formulation combining plant-derived surfactants, natural oils, and water-soluble ingredients that work together to provide effective makeup removal performance comparable to synthetic formulations while achieving high natural content certification
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 a visually appealing, non-greasy, and effective makeup removal solution with high natural content, demonstrating excellent phase separation and ability to remove long-wear makeup without irritating the skin or eyes.
Implementation Method 1
a first visually distinct phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value that is greater than 15 cal1/2cm−3/2, a second visually distinct phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value less than 7.5 cal1/2cm−3/2, and a third visually distinct phase layer comprising at least one cosmetic solvent having a Hildebrand solubility parameter δ value that is between 8 and 10 cal1/2cm−3/2
Implementation Method 2
When left standing, 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
