Bornyl Acetate Malodor Neutralization via Acid Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current odor-neutralizing compositions, such as perfumes, often fail to effectively reduce malodors without masking them with intense fragrances, limiting their application and requiring high concentrations of perfumes.
Innovation Solution
A combination of isobornyl acetate or bornyl acetate with specific low molecular weight monocarboxylic acids, such as tiglic acid or hexenoic acid, which neutralize malodors without significant odor, allowing for broader fragrance options and reduced perfume usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If perfume compositions are used to mask malodors, then malodor intensity is reduced, but the perfume itself must have intense fragrance which limits application options and requires high concentrations
Solution Approach 1:
The patent introduces a mediator substance (borneol or isoborneol in combination with volatile organic acids) that acts between the malodor source and the perfume. This intermediary neutralizes malodors through chemical reaction, allowing perfumes of any desired type to be used without needing intense fragrances to overpower the malodor.
Solution Approach 2:
The patent changes the chemical parameters of the odor-neutralizing composition by combining borneol/isoborneol with specific volatile organic acids (formic, acetic, propionic, butyric, valeric, caproic acids). This parameter change creates a synergistic effect that enhances malodor neutralization, allowing reduction of perfume concentration while maintaining effectiveness.
2Object-affected harmful factors
If high concentrations of perfume oil are used to mask malodors, then malodor coverage is improved, but the intensity of fragrance increases which may be overwhelming
Solution Approach 1:
The patent converts the potentially harmful intense fragrance into a benefit by using odor-neutralizing active ingredients that chemically react with malodors. This allows effective malodor coverage with lower fragrance concentrations, as the neutralization mechanism provides coverage without the need for overwhelming scents.
3Object-affected harmful factors
If traditional perfume compositions are used for malodor masking, then malodors are covered, but the range of applicable fragrance types is limited
Solution Approach 1:
The patent creates a universal malodor-neutralizing system using borneol/isoborneol combined with volatile organic acids that can be paired with any type of perfume fragrance. This multi-functional approach allows the same active ingredient combination to work effectively with floral, fruity, woody, or any other fragrance type, greatly expanding adaptability.
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 combination of acetates and acids significantly enhances odor-neutralizing effectiveness, allowing for the use of less intense fragrances and broader fragrance options, effectively reducing malodor intensity without adding strong scents.
Implementation Method 1
combinations of bomyl or isobomyl acetate with certain low molecular weight monocarboxylic acids have shown surprising enhanced effectiveness in neutralizing malodors
Data Source
AI summary
Composition comprising bornyl or isobornyl acetate and certain acids are effective for reducing malodors. The acids have the formula R-COOH in which R is C1-5 aklyl or R is C3 or C4 alkylene optionally phenyl-substituted. These compositions can be used in perfumed products, household products and personal care products.
