Solid Cleansing Powder Composition for Mild, Low-Packaging Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid cleansing products face challenges in formulation and manufacturing, requiring specific solid forms of ingredients that are easily blendable into a uniform product, and often cause skin harshness, dryness, or irritation, while also having a high environmental impact due to large packaging and energy consumption.
Innovation Solution
A solid cleansing composition comprising at least a first and a second surfactant, totaling at least 60% by weight, in powder form, with optional pH adjusters, preservatives, and antioxidants, formulated to be dissolvable in water, reducing environmental impact and ensuring mild skin use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If liquid cleansers are used, then cleansing effectiveness is achieved, but environmental impact increases due to larger packaging and higher water content
Solution Approach 1:
The invention changes the physical state parameter of the cleanser from liquid to solid powder form. This parameter change eliminates the need for large volumes of water (typically >70% in liquid cleansers) and reduces packaging requirements while maintaining cleansing effectiveness through surfactant-based formulation
Solution Approach 2:
The solid powder cleanser is designed for single-use or limited-use packaging such as sachets, packets, stick packs, and pouches. This disposable approach eliminates the need for reusable bottles and tubes, reducing plastic waste and environmental impact while providing adequate cleansing performance
2Loss of substance
If solid cleansing products are used, then environmental impact is reduced, but formulation complexity increases due to requirement for specific solid forms that are easily blendable
Solution Approach 1:
The invention specifies physical state parameters for ingredients, requiring them to be in solid form at storage temperature and capable of forming a uniform powder mixture. This parameter specification ensures ease of manufacture through simple mixing processes while maintaining the environmental benefits of solid-form packaging
Solution Approach 2:
The cleanser formulation uses composite surfactant systems (combining anionic, cationic, amphoteric, and nonionic surfactants) that can be easily blended into a uniform powder. This composite approach simplifies manufacturing while delivering effective cleansing performance
3Reliability
If surfactant concentration is increased to improve cleansing, then cleansing effectiveness improves, but skin harshness and irritation increase
Solution Approach 1:
The invention uses a composite surfactant system comprising multiple types of surfactants (anionic, cationic, amphoteric, and nonionic) in balanced concentrations. This composite formulation achieves effective cleansing through synergistic interactions between different surfactant types while maintaining skin compatibility and reducing harshness
Solution Approach 2:
The invention carefully controls the concentration parameters of individual surfactant types within the powder formulation. By optimizing the balance between different surfactant concentrations and their ionic characteristics, the formulation achieves effective cleansing without exceeding skin tolerance thresholds for harshness and irritation
