Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid-based cleansing compositions face challenges such as agglomeration, undesirable viscosity, and insufficient lathering when used in humid or high-temperature environments, making them difficult to dispense and use effectively, especially in single-use applications.
Innovation Solution
A cleansing powder composition comprising a solid surfactant system with isethionate or taurate, an effervescent system with a dry acidic and alkaline material, a stabilizing system with a polysaccharide builder and carboxylic acid salt, and optionally a viscosity builder, which remains free-flowing and self-foaming, even under high humidity and temperature conditions, and is easy to hydrate for single-use applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid-based cleansing compositions are used, then easy dispensing and consumer use are achieved, but environmental impact increases due to plastic packaging and water content
Solution Approach 1:
The invention changes the physical state parameter from liquid to powder form, eliminating the need for plastic packaging and reducing water content while maintaining ease of use through effervescent activation upon contact with water
Solution Approach 2:
The powder composition is designed for single-use applications in biodegradable packaging, eliminating the need for reusable plastic bottles and pumps, thereby reducing environmental impact while maintaining consumer convenience
2Quantity of substance
If concentrate form is used to reduce water content, then environmental impact decreases, but agglomeration occurs under high humidity and temperature conditions
Solution Approach 1:
The invention modifies the physical and chemical parameters of the concentrate by incorporating effervescent agents and specific surfactant systems that prevent agglomeration through gas evolution and maintain powder flowability under high humidity and temperature conditions
Solution Approach 2:
The effervescent system acts as an intermediary mechanism that generates gas bubbles during hydration, preventing direct contact between water and powder particles that would cause agglomeration, while also enhancing the self-lather formation
3Quantity of substance
If concentrate is used to reduce water content, then shipping efficiency improves, but viscosity is insufficient after hydration
Solution Approach 1:
The invention incorporates viscosity builders and stabilizing systems in the powder formulation that are activated upon contact with water, pre-preparing the composition to achieve optimal viscosity and stability after hydration without requiring excessive water content
4Reliability
If conventional liquid formulations are used, then adequate lathering is achieved, but plastic packaging and water content increase environmental impact
Solution Approach 1:
The powder composition is designed to be self-foaming upon contact with water, eliminating the need for mechanical mixing or additional lather-building agents, thereby maintaining reliable lathering performance while reducing environmental impact through minimal packaging and water content
