Foamable Solid Cleanser Segmentation and Composite Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid cleansing products typically do not foam quickly enough or provide desired foam stability, and they lack moisturizing and skin conditioning benefits, making them unsuitable for effective personal use, especially on the skin or face.
Innovation Solution
A solid cleansing product formulation that includes a combination of surfactants, skin conditioning agents, buffering agents, and other additives, which transforms into a foamy, cushiony texture upon contact with water, providing enhanced foaming, cleansing, and moisturizing properties while maintaining skin health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid cleansing products are used, then leakage and spillage are prevented and packaging size is reduced, but foaming speed and foam stability are insufficient
Solution Approach 1:
The solid cleansing product is segmented into multiple functional components: surfactants for foaming, effervescent agents for rapid dissolution, binders for structural integrity, and moisturizing agents for skin care. This segmentation allows each component to perform its specific function optimally, enabling fast foaming while maintaining solid form stability
Solution Approach 2:
The invention uses composite material formulation combining surfactants, effervescent agents, binders, and moisturizing agents in a solid matrix. This composite structure enables the product to simultaneously provide rapid foaming, structural stability for leak-free transport, and additional skin benefits, resolving the contradiction between solid form reliability and foaming performance
2Volume of stationary object
If solid cleansing products are used, then packaging size is reduced, but foam stability is insufficient
Solution Approach 1:
The effervescent agents (sodium bicarbonate and citric acid) are pre-positioned in the solid matrix to react upon contact with water, creating carbon dioxide bubbles that rapidly expand the formulation and incorporate air. This preliminary action ensures stable foam formation immediately upon use, while the compact solid form minimizes packaging volume
Solution Approach 2:
The invention changes the physical and chemical parameters of the foam by adjusting surfactant concentration, effervescent agent ratios, and binder types. These parameter optimizations ensure that the foam maintains stability and structure throughout the cleansing process, resolving the contradiction between compact packaging and foam stability
3Ease of operation
If traditional solid cleansers are used, then convenience is improved, but moisturizing and skin conditioning benefits are lacking
Solution Approach 1:
The solid cleansing product is designed with multi-functionality, combining cleansing, foaming, and moisturizing capabilities in a single formulation. Moisturizing agents (glycerin, aloe vera, vitamin E) and skin conditioning agents are integrated into the solid matrix, allowing the product to deliver multiple benefits simultaneously while maintaining the convenience of solid form usage
Solution Approach 2:
The effervescent reaction acts as an intermediary mechanism that facilitates the release of moisturizing and skin conditioning agents during use. As the solid product dissolves and foams, these beneficial agents are gradually released and delivered to the skin, bridging the gap between convenient solid form application and effective skin care
