Antifoamer Polymer Phenyl Content for Suds Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning and treatment compositions with antifoamers often face stability issues due to incompatibility with other components, primarily attributed to high levels of phenyl moieties in the polymer component, leading to unwanted suds levels.
Innovation Solution
Developing compositions with antifoamers that limit phenyl moieties in the polymer component to less than 10%, ensuring compatibility and stability while maintaining desired suds profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high levels of phenyl moieties are used in the polymer component of the antifoamer, then the antifoaming performance is improved, but the stability and compatibility with other compositional components deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying the phenyl moiety content in the polymer component from the conventional high level (at least 10-15%) to a controlled lower level (less than 10%). This parameter adjustment resolves the contradiction by maintaining sufficient antifoaming performance while eliminating the stability and compatibility issues caused by excessive phenyl moieties interacting with other compositional ingredients
2Ease of operation
If antifoamer is added to reduce suds levels, then the suds control is improved, but the product stability deteriorates due to incompatibility with other components
Solution Approach 1:
The patent resolves this contradiction by changing the phenyl moiety parameter in the antifoamer polymer to less than 10%, which enables the antifoamer to effectively control suds levels without causing incompatibility or stability problems with other compositional components
Solution Approach 2:
The patent references and builds upon the antifoamer composition structure from U.S. Pat. No. 7,619,043 B2, copying the base polymer architecture while modifying the phenyl moiety content parameter to achieve both suds control and stability
