Polyurethane-34 Cleansing Compositions for Bacterial Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleansing compositions fail to prevent bacteria from re-attaching to the skin after skin contact with bacteria-contaminated surfaces during cleansing.
Innovation Solution
Incorporating polyurethane-34 into cleansing compositions, such as body washes and liquid hand soaps, which forms a barrier on the skin to prevent bacteria attachment, using a cleansing effective amount of surfactants and polyurethane-34 in various weight percentages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional cleansing compositions are used, then skin is cleaned, but bacteria can re-attach to skin after cleansing
Solution Approach 1:
The polyurethane-34 polymer is incorporated into the cleansing composition to pre-form a protective barrier on the skin during the cleansing process itself, rather than requiring a separate application step. This preliminary action ensures bacteria are blocked from attaching in the first place
Solution Approach 2:
The invention combines surfactants with polyurethane-34 polymer to create a composite cleansing composition that provides both cleaning and protective barrier functions simultaneously, addressing the limitation of conventional single-function cleansers
2Object-affected harmful factors
If a protective barrier is applied to skin, then bacteria attachment is prevented, but an additional step is required beyond cleansing
Solution Approach 1:
The invention merges the cleansing function and protective barrier formation into a single integrated product. The polyurethane-34 polymer is included in the cleansing composition itself, so that one application performs both cleaning and protection functions simultaneously
Solution Approach 2:
The cleansing composition is designed to perform multiple functions: cleaning the skin and forming a protective barrier against bacteria. This multi-functionality eliminates the need for separate products or application steps
3Reliability
If polyurethane-34 is added to cleansing composition, then protective barrier is formed, but composition complexity increases
Solution Approach 1:
The invention specifies optimal concentration ranges for polyurethane-34 (0.1-5% by weight) to achieve effective barrier formation while maintaining formulation simplicity. This parameter optimization balances performance with compositional complexity
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
Polyurethane-34 effectively reduces or prevents bacteria attachment to the skin, as demonstrated by significant reduction in dye uptake on skin samples, showing its efficacy in forming a protective barrier during and after cleansing.
Implementation Method 1
the polyurethane-34 can deposit on skin and form a barrier. The barrier can reduce or prevent bacteria from attaching to skin
Data Source
AI summary
