Moldable Solid Cleansing Composition with Phase Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing makeup removal products, particularly anhydrous oil-based balms, are difficult to apply and require a separate cleansing step due to their solid form, leading to user dissatisfaction and inefficiency in removing makeup.
Innovation Solution
Development of an anhydrous composition comprising an oil phase with linear fatty esters and non-ionic surfactants that is solid at ambient temperature but transitions to a cream upon application, providing a moldable and pre-measured format for effective makeup removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anhydrous oil-based balm is used for makeup removal, then effective makeup removal is achieved, but the product is difficult to apply and requires separate cleansing step
Solution Approach 1:
The patent changes the physical state parameter of the cleansing composition from solid to moldable at ambient temperature, allowing it to be easily shaped and applied while maintaining effective makeup removal capabilities
Solution Approach 2:
The composition transitions from a solid state during storage to a moldable state during application, providing dynamic adaptability that enables both effective makeup removal and ease of application without requiring separate cleansing steps
2Manufacturing precision
If solid form composition is used, then pre-measured format is achieved, but difficult to apply and requires separate cleansing step
Solution Approach 1:
The patent modifies the physical state parameter to create a moldable composition that can be precisely measured during manufacturing while remaining easily manipulable during application, eliminating the need for separate cleansing steps
3Stability of the object's composition
If solid form composition is used, then stability during storage is achieved, but not travel-friendly and difficult to apply
Solution Approach 1:
The patent adjusts the physical state parameter to create a moldable composition that maintains stability during storage while becoming easily applicable during use, making it travel-friendly and eliminating the need for separate cleansing steps
Applied Scientific Principles

Data Source
AI summary
Described herein are anhydrous compositions including at least one oil phase and at least one non-ionic surfactant. The oil phase includes one or more linear (i.e., unbranched) fatty esters, such as cetyl palmitate. The oil phase can further include at least one branched fatty esters, such as ethylhexyl palmitate and/or isocetyl stearate.
