Mint-Rosemary Oil Pest Control Composition for Odor-Efficacy Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insecticide and insect repellent compositions have unpleasant, harsh, and lingering chemical odors, compromising their efficacy when reduced chemical concentrations are used to mitigate these odors.
Innovation Solution
A pest control composition comprising a synergistic blend of mint oils (spearmint, peppermint, or cornmint) and rosemary oil, along with a carrier, solvent, and dehydrate, providing a pleasant fragrance while maintaining high insecticidal and repellent efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If chemical concentrations are reduced to mitigate harsh odors, then odor pleasantness is improved, but insecticidal efficacy deteriorates
Solution Approach 1:
The patent combines multiple essential oils (mint oil and rosemary oil) in a synergistic formulation to achieve both pleasant odor and high insecticidal efficacy. This merging of natural components allows the composition to maintain effectiveness while providing a comfortable fragrance, resolving the contradiction between reducing chemical odor and maintaining efficacy.
Solution Approach 2:
The patent optimizes the concentration parameters of essential oils within specific ranges (mint oil: 0.1-11 wt%, rosemary oil: 0.05-5 wt%) to achieve the desired balance between odor quality and insecticidal activity. By carefully controlling these parameters, the formulation maintains high efficacy while providing a pleasant fragrance.
2Object-affected harmful factors
If chemical concentrations are reduced to mitigate harsh odors, then environmental safety is improved, but pest control effectiveness deteriorates
Solution Approach 1:
The patent employs essential oils as natural, biodegradable active ingredients that break down easily in the environment. These natural components provide effective pest control while being environmentally safe, eliminating the need for persistent synthetic chemicals that cause environmental damage.
Solution Approach 2:
The patent converts the natural fragrance properties of essential oils into a beneficial feature that masks harsh chemical odors while maintaining pest control effectiveness. The natural compounds provide both odor pleasantness and insecticidal activity, turning potential drawbacks into advantages.
3Object-affected harmful factors
If essential oils are used to mask harsh odors, then odor pleasantness is improved, but composition complexity increases
Solution Approach 1:
The patent extracts and isolates specific active components from natural plants (mint and rosemary oils) to create a focused formulation. By using purified essential oils rather than complex plant extracts, the composition achieves odor pleasantness while maintaining relative simplicity in its ingredient list and formulation.

AI summary
A pest control composition, in one embodiment the composition including an active component that includes between about 0.1 wt. % and about 11 wt. % of a mint oil and between about 0.05 wt. % and about 5 wt. % rosemary oil. The composition may further include a carrier or a solvent, and a dehydrate, where all weight percentages are percent by weight of the total composition. In one embodiment a weight ratio of the dehydrate to the mint oil is preferably greater than 1.
