Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleansing compositions fail to provide a clear, mild, foaming, and moisturizing solution that maintains skin hydration for an extended period while ensuring clarity and mildness.
Innovation Solution
A clear cleansing composition comprising 0.05 to 30 weight percent anionic surfactant, 0.5 to 20 weight percent amphoteric or nonionic surfactant, and 0.1 to 50 weight percent humectant, which provides moisturization for at least 4 hours, ensuring clarity, mildness, and effective foaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a cleansing composition uses traditional surfactant formulations, then it achieves good foaming and cleansing, but it fails to provide extended moisturization and clarity
Solution Approach 1:
The patent employs a composite surfactant system combining anionic surfactants (0.05-30 wt%) with amphoteric surfactants (0.5-20 wt%) and nonionic surfactants (0.1-20 wt%). This multi-component surfactant complex achieves both effective cleansing and extended moisturization (at least 4 hours) that single surfactant types cannot provide alone, resolving the contradiction between cleansing reliability and moisturization duration.
Solution Approach 2:
The patent optimizes specific parameter ranges for each surfactant type to achieve the desired balance. By controlling the anionic surfactant at 0.05-30 wt%, amphoteric at 0.5-20 wt%, and nonionic at 0.1-20 wt%, the formulation achieves both reliable cleansing performance and extended moisturization duration of at least 4 hours, resolving the contradiction between these two requirements.
2Duration of action of moving object
If the composition includes multiple surfactant types for moisturization, then moisturization duration improves, but formulation complexity increases
Solution Approach 1:
The patent uses a composite surfactant system with three types of surfactants in specific ranges (anionic: 0.05-30 wt%, amphoteric: 0.5-20 wt%, nonionic: 0.1-20 wt%). This composite approach achieves extended moisturization duration of at least 4 hours while maintaining manageable formulation complexity through defined concentration ranges for each component.
3Object-affected harmful factors
If the composition aims for clarity and mildness, then consumer appeal and skin gentleness improve, but foaming capability may be reduced
Solution Approach 1:
The patent combines anionic surfactants (0.05-30 wt%) with amphoteric (0.5-20 wt%) and nonionic (0.1-20 wt%) surfactants to create a composite system that maintains good foaming capability while achieving mildness (reduced skin irritation). The synergistic interaction between these surfactant types allows the formulation to be both gentle on skin and effectively foaming.
Solution Approach 2:
The patent optimizes surfactant concentration parameters to balance mildness and foaming. By controlling anionic surfactant at 0.05-30 wt%, amphoteric at 0.5-20 wt%, and nonionic at 0.1-20 wt%, the formulation achieves reduced skin irritation while maintaining good foaming capability, resolving the contradiction between these two properties.
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 excellent moisturization duration, mildness, and good foaming properties, maintaining skin hydration for extended periods while maintaining clarity and being gentle on the skin.
Implementation Method 1
The composition comprises... a humectant, wherein said composition provides moisturization duration for at least about 4 hours
Implementation Method 2
The composition comprises an anionic surfactant, an additional surfactant that is an amphoteric surfactant, a nonionic surfactant... delivers good foaming

AI summary
A clear cleansing composition that also provides excellent moisturization is described. The composition comprises about 0.05 to about 30 weight percent anionic surfactant, an additional surfactant selected from about 0.5 to about 20 weight percent amphoteric surfactant, about 0.1 to about 20 weight percent nonionic surfactant, or both, and about 0.1 to about 50 weight percent humectant. Advantageously, the composition is also mild.
