Alkanediol and Cooling Agent Composition for Malodour Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current homecare, cosmetic, and pharmaceutical products are inadequate in effectively reducing or inhibiting malodour development and body odour, as they often fail to simultaneously address sweat reduction, microbial activity inhibition, and odour masking, while requiring toxicological acceptability, skin tolerability, stability, and ease of formulation.
Innovation Solution
A composition comprising 1,2-nonanediol, 2,3-nonanediol, or a mixture of alkanediols in combination with a cooling agent and optionally antimicrobial compounds, providing a synergistic effect for malodour reduction, sweat inhibition, and odour masking, suitable for various product forms like deodorants and homecare products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional homecare, cosmetic, and pharmaceutical products are used, then basic deodorant functions are provided, but they fail to effectively reduce or inhibit malodour development and body odour while addressing sweat reduction, microbial activity inhibition, and odour masking simultaneously
Solution Approach 1:
The patent combines multiple functional components into a single deodorant composition: alkanediols (for sweat reduction and microbial inhibition), cooling agents (for sensory cooling and additional malodour reduction), and antimicrobial compounds (for enhanced microbial activity inhibition). This merging allows the product to simultaneously address sweat reduction, microbial activity inhibition, and odour masking, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The invention uses a composite formulation comprising multiple active ingredients working synergistically: alkanediols (C5-C14 linear chains), cooling agents (such as menthol, eucalyptol, or other terpenes), and optional antimicrobial compounds. This composite material approach enables the single product to deliver multiple functions (sweat reduction, microbial inhibition, odour masking) simultaneously, achieving both high reliability and versatility.
2Reliability
If multiple active ingredients are combined to achieve synergistic effects, then malodour reduction and antimicrobial efficacy are improved, but formulation complexity increases
Solution Approach 1:
The patent specifies particular parameter ranges for the alkanediols (linear chains with 5-14 carbon atoms, preferably 7-11 carbons) and defines specific concentration ranges for each component (alkanediols: 0.1-20%, cooling agents: 0.01-5%, antimicrobial compounds: 0.1-10%). By optimizing these parameters, the formulation achieves synergistic effects with improved malodour reduction and antimicrobial efficacy while maintaining manageable formulation complexity through standardized concentration guidelines.
3Reliability
If new compounds are searched for malodour reduction, then odour control effectiveness may be improved, but toxicological acceptability and skin tolerability requirements must be met
Solution Approach 1:
The patent selects alkanediols with specific carbon chain lengths (C5-C14, preferably C7-C11) and defines safe concentration ranges (0.1-20%) based on toxicological considerations. These parameter specifications ensure that the compounds provide effective odour control while maintaining toxicological acceptability and skin tolerability, as the chosen alkanediols are recognized as safe cosmetic ingredients at the specified concentrations.
Solution Approach 2:
The invention uses well-established, safe cosmetic ingredients (alkanediols, cooling agents like menthol, and common antimicrobial compounds) rather than experimenting with novel, potentially hazardous substances. This approach prioritizes toxicological acceptability and skin tolerability while still achieving effective odour control through the synergistic combination of proven safe ingredients at optimized concentrations.
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 composition effectively reduces malodour, inhibits its development, and controls body odour through sweat reduction and antimicrobial action, while being toxicologically acceptable, stable, and easy to formulate, with enhanced odour masking capabilities.
Implementation Method 1
at least one cooling agent... providing a synergistic effect for malodour reduction, sweat inhibition, and odour masking
Implementation Method 2
The compounds produced by microbes from human or animal sweat, and the compounds directly produced by the apocrine sweat glands also lead to a malodour smell of old age
