Water-Soluble Non-Woven Wipe for Bottle-Free Facial Cleansing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic cleansing routines rely on liquid products and disposable wipes made from cotton or polymeric fibers, which are not recyclable and do not provide a convenient, 'bottle-free' facial cleansing solution that combines multiple functionalities like makeup removal and cleansing.
Innovation Solution
Development of water-soluble non-woven cleansing pads comprising fibers such as polyvinyl alcohol, which are soluble in water at 30°C or less, allowing for a single product to dissolve into a liquid cleanser for skin washing after makeup removal, eliminating the need for additional liquid products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cotton or polymeric fiber wipes are used for cleansing, then the wipes provide durability and absorbency, but they are not recyclable and require separate liquid product containers
Solution Approach 1:
The patent combines multiple cleansing functions (makeup removal, cleansing, moisturizing) into a single water-soluble wipe that dissolves in water to release embedded surfactants and active ingredients. This eliminates the need for separate liquid product containers and simplifies the overall product system while maintaining multi-functionality.
Solution Approach 2:
The water-soluble wipe serves multiple functions: it acts as a physical cleaning tool, a carrier for surfactants, a source of moisturizing ingredients, and an environmentally friendly disposable product. The single product replaces traditional multi-product cleansing routines.
2Ease of operation
If liquid cleansers are used in separate containers, then the products provide effective cleansing, but the packaging is not recyclable and requires additional storage and transportation
Solution Approach 1:
The patent employs a disposable water-soluble wipe that is used once and then dissolves completely in water, leaving no waste. The wipe is made from water-soluble polymers that break down into harmless components, eliminating the need for recyclable packaging and reducing environmental waste.
Solution Approach 2:
After use, the wipe is discarded by simply rinsing it in water where it dissolves completely, releasing the embedded surfactants and active ingredients. The dissolved components are washed away with water, leaving no residual waste requiring separate disposal or recycling processes.
3Reliability
If water-soluble fibers are used to create dissolvable wipes, then the wipes can be disposed of by flushing, but the fibers must remain durable when contacted with anhydrous formulations
Solution Approach 1:
The patent uses water-soluble polymers with specific molecular weight ranges and hydrolysis levels that provide different properties in different conditions. The fibers remain durable and structurally intact when dry or in anhydrous formulations, but dissolve completely when exposed to water, achieving both durability and water solubility through localized material properties.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The water-soluble pads offer a sustainable, economical, and convenient 'bottle-free' facial cleansing solution by combining makeup removal and cleansing functionalities in a single product, reducing waste and eliminating the need for separate liquid products.
Implementation Method 1
the sheets are soluble in running or standing water having a temperature of 30° C. or less
Implementation Method 2
the fibers comprise a hydrophobic coating
