Antioxidant Particle Composition for Lasting Surface Malodor Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surface treatment compositions face challenges in effectively depositing antioxidants onto surfaces due to interactions with surfactants, leading to reduced efficacy and discoloration, while perfumes only mask malodor without addressing the underlying issue, and consumers prefer perfume-free solutions.
Innovation Solution
Formulating antioxidants in a solid matrix with a water-soluble carrier, eliminating the need for surfactants, which allows for effective deposition and prolonged malodor reduction without discoloration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If antioxidants are incorporated into detergent compositions with surfactants for dispersion, then the antioxidant can be deposited onto surfaces, but the surfactants interact with antioxidants and hinder the level of antioxidant deposited onto the surface
Solution Approach 1:
The patent introduces a nonionic surfactant as an intermediary substance that mediates between the antioxidant and other components in the detergent composition. This specific type of surfactant is selected because it disperses the antioxidant effectively while minimizing harmful interactions, thereby maintaining high levels of antioxidant deposition on surfaces without the negative effects of surfactant-antioxidant interactions
2Reliability
If antioxidants are deposited onto surfaces to reduce malodor, then malodor reduction is achieved, but the antioxidants are lost from the surface over time due to consumption, transfer, or sublimation
Solution Approach 1:
The patent ensures continuous malodor reduction by formulating the detergent composition with sufficient antioxidant concentration that compensates for gradual loss. The composition maintains a reservoir of antioxidants that continuously deposit onto surfaces over time, ensuring the antioxidant level remains effective for malodor reduction even as some antioxidants are consumed, transferred, or sublime
Solution Approach 2:
The patent uses encapsulated antioxidants that release the active antioxidant component gradually. The encapsulation structure acts as a carrier that mimics the natural release pattern, providing sustained deposition of antioxidants onto surfaces over extended periods, thereby extending the duration of malodor reduction effectiveness
3Object-generated harmful factors
If perfumes are incorporated into treatment processes to mask malodor, then malodor is masked, but perfumes act only to mask and do not address the underlying problem of remaining soils
Solution Approach 1:
The patent converts the underlying cause of malodor (remaining soils) into a benefit by using antioxidants to prevent the chemical reactions that generate malodorous materials. Instead of merely masking the symptom (malodor), the antioxidants address the root cause by retarding autoxidation events in remaining soils, thereby transforming the problem of residual soils into a solution that prevents malodor formation at its source
4Quantity of substance
If antioxidants are used at low levels in treatment products, then the product formulation is economical, but the deposited antioxidants may be lost from the surface over time
Solution Approach 1:
The patent optimizes the concentration parameters of antioxidants in the detergent composition by incorporating specific amounts of antioxidant materials. The formulation uses sufficient antioxidant concentration to compensate for gradual loss over time while maintaining economical product formulation. The nonionic surfactant enhances the efficiency of antioxidant deposition, allowing effective malodor reduction with optimized antioxidant levels
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 treatment compositions provide long-lasting malodor reduction by ensuring antioxidants remain on surfaces, preventing soil-induced malodor formation and maintaining product color integrity.
Implementation Method 1
retarding autoxidation events in remaining soils even after the treatment process, that lead to the formation of malodorous materials
Implementation Method 2
Antioxidants may be deposited from an aqueous solution onto the surface during the treatment process
Implementation Method 3
the deposited antioxidants may be lost from the surface over time due to, for example, consumption of the antioxidant, transfer through physical contact with other objects or, as Applicant has found, by sublimation
Implementation Method 4
for the antioxidant to even deposit on the surface, it must be properly dispersed by a dispersing agent
