Three-Phase Cosmetic Composition With Clear Stable Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing triphasic cosmetic compositions lack stability and clarity, often containing silicone oil or paraffin, and fail to meet consumer demand for naturally derived ingredients while maintaining effective makeup removal and skin/hair care properties.
Innovation Solution
A three-phase cosmetic composition comprising a lower aqueous phase with at least 50% glycerin, an intermediate non-siliconized oily phase with castor oil, and an upper non-siliconized oily phase with linear or branched C10-C20 alkanes, ensuring clear interfaces and effective makeup removal without synthetic oils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If silicone oil or paraffin is used in triphasic compositions, then stability and interface clarity are improved, but natural ingredient content decreases and consumer acceptance worsens
Solution Approach 1:
The patent changes the chemical composition parameters by replacing silicone oil and paraffin with vegetable-derived oils (castor oil, jojoba oil, argan oil) and adjusting the aqueous phase composition to achieve stable phase separation without synthetic ingredients. This parameter substitution resolves the contradiction between stability and natural ingredient content.
Solution Approach 2:
The patent uses readily available vegetable oils that are naturally derived and biodegradable, replacing persistent synthetic oils. These natural ingredients provide the necessary functional properties while being environmentally friendly and consumer-accepted, effectively substituting the harmful synthetic components.
2Object-generated harmful factors
If alcohol is used in triphasic compositions to avoid silicone oil, then natural ingredient content is improved, but makeup removal effectiveness worsens
Solution Approach 1:
The patent creates a composite oily phase combining multiple vegetable oils (castor oil, jojoba oil, argan oil) with complementary properties. Castor oil provides strong makeup removal capability, while jojoba and argan oils provide moisturizing and stabilizing effects. This composite natural oil system achieves both effective makeup removal and natural ingredient compliance.
Solution Approach 2:
The patent merges multiple vegetable oils with different functional properties into a unified oily phase system. By combining the solubilizing power of castor oil with the emollient properties of jojoba and argan oils, the composition achieves comprehensive makeup removal effectiveness while maintaining 100% natural ingredient status.
3Object-generated harmful factors
If aqueous phase content is increased to meet consumer preferences, then natural ingredient content is improved, but phase separation clarity worsens
Solution Approach 1:
The patent introduces vegetable oils as intermediary substances between the aqueous and oily phases. These natural oils act as mediators that facilitate clear phase separation while maintaining high aqueous content. The vegetable oils provide the necessary interfacial properties to achieve clarity without requiring synthetic additives.
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 achieves stable, clear interfaces and effective makeup removal, suitable for skin and hair care, while being free from silicones and paraffins, meeting consumer preferences for natural ingredients.
Implementation Method 1
the lowest phase at rest is generally the aqueous phase, which is the densest, while at least one of the middle and upper phases is an oily phase
