2-Amino-1,3-propanediol for Neutralizing Aldehyde Off-Odors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing, cleaning, and care products fail to effectively reduce off-odors caused by aldehydes and ketones, particularly short-chain aldehydes, which are common contributors to undesirable smells in various environments.
Innovation Solution
The use of 2-amino-1,3-propanediol and/or substituted 2-amino-1,3-propanediol, either alone or in combination with fragrances and surfactants, in washing, cleaning, or care products to neutralize and eliminate off-odors by being added to the affected area or system, either through spraying, incorporation into detergents, or use in textile treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional washing, cleaning, and care products are used, then general cleaning function is provided, but off-odors caused by aldehydes and ketones cannot be effectively reduced
Solution Approach 1:
The patent converts the harmful aldehydes and ketones into beneficial substances by using amino-1,3-propanediol and substituted 2-amino-1,3-propanediol to react with these odor-causing compounds, transforming them into non-odorous or less odorous products through chemical reaction
Solution Approach 2:
The patent introduces amino-1,3-propanediol and substituted 2-amino-1,3-propanediol as intermediary substances that mediate between the odor-causing aldehydes/ketones and the desired odor-free state, facilitating the chemical transformation of harmful compounds
2Object-affected harmful factors
If 2-amino-1,3-propanediol and substituted 2-amino-1,3-propanediol are added to reduce off-odors, then odor reduction effectiveness is significantly improved, but product formulation complexity increases
Solution Approach 1:
The patent applies amino-1,3-propanediol and substituted 2-amino-1,3-propanediol across multiple product types including washing agents, cleaning agents, and care products, allowing a single active ingredient to serve multiple functions and applications while maintaining consistent odor reduction effectiveness
Solution Approach 2:
The patent optimizes the concentration parameters of amino-1,3-propanediol and substituted 2-amino-1,3-propanediol in product formulations to achieve effective odor reduction while controlling formulation complexity, using specific amount ranges to balance performance and simplicity
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
Significantly reduces bad odors attributed to ketones and aldehydes, providing an improved scent experience and odor control in textiles, hard surfaces, and air care applications, while being stable and versatile for various uses.
Implementation Method 1
The use of amino-1,3-propanediol and/or substituted 2-amino-1,3-propanediol, either alone or in combination with fragrances and surfactants, in washing, cleaning, or care products to neutralize and eliminate off-odors by being added to the affected area or system
