Unscented Malodor Control Composition Using Chemical Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current unscented and low scented malodor control products face challenges in effectively reducing a broad range of malodors, particularly amine-based and sulfur-based odors, often relying on masking scents rather than true neutralization, which can lead to consumer doubt in their efficacy.
Innovation Solution
A malodor control composition comprising a perfume mixture with benzophenone, methyl palmitate, farnesol, vetivert acetate, and undecylenic aldehyde, optionally with an acid catalyst, that neutralizes and blocks malodors through odor neutralization and blocking technologies, rather than just masking them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scented perfumes are incorporated to mask malodors, then malodor control efficacy is improved, but scent intensity increases
Solution Approach 1:
The patent converts the harmful malodors into beneficial effects by using chemical neutralization. Specifically, it employs acidic compounds (like citric acid, acetic acid) to neutralize basic malodors (amines, ammonia) and basic compounds to neutralize acidic malodors (sulfur compounds), transforming the harmful odor molecules into non-odorous or less odorous substances through chemical reactions.
Solution Approach 2:
The patent changes the chemical parameters of the malodor control composition by using compounds with specific pH values and chemical properties. It selects materials with appropriate acidity/basicity levels, molecular weights, and reactivity to target specific malodor types, allowing effective neutralization without relying on masking fragrances.
2Object-generated harmful factors
If unscented or low scented products are used, then consumer acceptance is improved, but malodor control efficacy deteriorates
Solution Approach 1:
The patent converts the harmful malodors into beneficial effects by using chemical neutralization. Specifically, it employs acidic compounds (like citric acid, acetic acid) to neutralize basic malodors (amines, ammonia) and basic compounds to neutralize acidic malodors (sulfur compounds), transforming the harmful odor molecules into non-odorous or less odorous substances through chemical reactions.
Solution Approach 2:
The patent uses composite material strategies by combining multiple neutralizing agents with complementary properties. It formulates compositions containing both acidic and basic compounds, along with buffering agents and adjuvants, to create a synergistic system that effectively handles diverse malodor types (amine-based, sulfur-based, organic acids) without requiring strong fragrances for masking.
