Solid Tablet Cleanser with Starch and Flour for Gentle Exfoliation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial skin care cleansing products often rely on synthetic preservatives, added water, and coatings, which are not environmentally friendly and can be harsh on the skin, while also lacking in gentle exfoliation and hydration.
Innovation Solution
A solid tablet cosmetic cleansing composition comprising starch, flour, surfactants, and natural ingredients like vegetable oil, enzymes, and antioxidants, which can be crushed into a powder and mixed with water to form a lather, eliminating the need for synthetic preservatives and water, and providing gentle exfoliation and hydration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic preservatives, added water, and coatings are used in facial cleansers, then product stability and shelf life are improved, but environmental friendliness and skin gentleness deteriorate
Solution Approach 1:
The patent removes synthetic preservatives, added water, and coatings from the facial cleanser formulation. The solid tablet form inherently prevents microbial growth without requiring synthetic preservatives, while the absence of added water eliminates the need for preservative systems. This extraction of harmful components directly resolves the contradiction by maintaining product stability through formulation design rather than chemical additives.
Solution Approach 2:
The patent changes the physical state of the cleanser from liquid to solid tablet form. This parameter change fundamentally alters the product's stability characteristics - the solid state prevents microbial proliferation and maintains formulation integrity without requiring synthetic preservatives.同时, the solid tablet can be crushed between fingers to form a powder that mixes with water to create lather, providing gentle exfoliation while maintaining skin compatibility.
2Duration of action of stationary object
If synthetic preservatives and coatings are used, then product shelf life is extended, but environmental friendliness deteriorates
Solution Approach 1:
The patent employs a solid tablet formulation that is designed to be used up completely. Each tablet is a self-contained, disposable unit that dissolves during use, leaving no persistent synthetic preservatives or coatings in the environment. This approach extends effective shelf life through proper storage of the stable solid formulation while ensuring complete biodegradability upon use, thus resolving the contradiction between shelf life and environmental friendliness.
3Reliability
If a solid tablet form is used without added water, then product stability and environmental friendliness are improved, but product complexity in formulation increases
Solution Approach 1:
The patent creates a composite solid tablet formulation combining multiple functional ingredients - surfactants for cleansing, starch and flour for exfoliation and texture, vegetable oils for moisturization, and natural antioxidants for skin protection. This composite approach achieves product stability without added water while incorporating multiple benefits in a single unified formulation, resolving the contradiction between stability and formulation complexity.
4Ease of operation
If starch and flour are included for exfoliation, then gentle exfoliation is provided, but manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes the natural particle size distribution of starch and flour ingredients to provide gentle exfoliation. Rather than requiring precise particle size control, the formulation leverages the inherent properties of these natural ingredients, where the varied particle sizes create effective mechanical exfoliation. The solid tablet form maintains these particles in a stable state until use, when they are released upon crushing and mixing with water, thus resolving the contradiction between gentle exfoliation and manufacturing precision requirements.
