Personal Cleansing Composition with Natural Surfactants and OPI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grading systems for personal cleansing products do not adequately consider the environmental impact and performance attributes, often requiring manufacturers to sacrifice one factor for another, such as biodegradability, low toxicity, and efficacy.
Innovation Solution
A personal cleansing composition is formulated using primary and secondary surfactants, humectants, and polymeric conditioners all originating from natural and renewable resources, with specific weight percentages and an Optimum Performance Index (OPI) calculation to ensure high consumer performance and environmental responsibility, including low carbon dioxide emissions and high biodegradability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional grading systems are used to evaluate environmental impact, then environmental attributes are considered, but product efficacy and performance attributes are not taken into account
Solution Approach 1:
The patent merges environmental evaluation criteria with performance evaluation criteria into a unified formulation system. The composition simultaneously addresses biodegradability, low toxicity, and consumer performance by selecting specific combinations of surfactants, humectants, and conditioners that satisfy both environmental grading requirements and performance thresholds, thereby resolving the contradiction between environmental attributes and product efficacy.
Solution Approach 2:
The patent changes the formulation parameters by specifying precise concentration ranges for different ingredient classes (primary surfactants at 2-15 wt.%, secondary surfactants at 1-10 wt.%, humectants at 1-10 wt.%, conditioners at 0.1-5 wt.%) to achieve an Optimum Performance Index of at least 5.450. This parameter optimization allows the composition to meet both environmental standards and performance requirements simultaneously.
2Object-generated harmful factors
If natural and renewable resources are used to improve environmental characteristics, then biodegradability and low toxicity are enhanced, but product performance may be compromised
Solution Approach 1:
The patent employs composite material principles by combining multiple surfactant types (anionic, amphoteric, nonionic) with humectants and conditioning agents in specific ratios. This composite formulation approach allows the natural and renewable resource-based ingredients to work synergistically, achieving both high biodegradability and consumer-satisfying performance attributes including skin feel, lather, and cleansing efficacy.
Solution Approach 2:
The patent optimizes performance parameters by controlling the concentration of each ingredient class and calculating the Optimum Performance Index (OPI). By adjusting these parameters within specified ranges and maintaining an OPI of at least 5.450, the composition achieves satisfactory consumer performance while using only natural and renewable resources that ensure high biodegradability.
3Reliability
If multiple ingredient components are combined to achieve high performance, then consumer satisfaction is improved, but environmental impact increases
Solution Approach 1:
The patent reduces environmental footprint by optimizing ingredient concentrations and formulating a composition with total solids content of 10-30 wt.%. The specific parameter control ensures that sufficient performance is achieved with minimal ingredient quantities, and all ingredients selected are from natural and renewable resources with high biodegradability, thereby reducing the overall environmental impact despite using multiple functional components.

AI summary
A method is provided for formulating a personal cleansing composition. At least one primary surfactant, at least one secondary amphoteric and/or nonionic surfactant, at least one humectant, and at least one polymeric and/or quaternary conditioner are selected, each of these components having a natural and renewable resource origin. The primary and secondary surfactants are combined with the at least one humectant and the at least one conditioner in a final composition that includes the combined primary and secondary surfactants at less than about 14 wt. %, and includes the combined at least one humectant and at least one conditioner at less than 5.5 wt. %. After forming the final composition, an optimum performance index (OPI) is determined for the composition to ensure that the composition has an OPI of at least about 5.450. The OPI is calculated as: OPI=3÷((solids wt. %+Zein score)÷performance grade).
