Natural Essential Oil Insect Repellent Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chemical insecticides are toxic to humans, animals, and the environment, requiring hazardous handling and storage, and often have limited effectiveness with significant side effects, necessitating the development of a non-toxic, long-lasting insect repellent formulation.
Innovation Solution
A safe, non-toxic insect repellent formulation comprising natural essential oils such as cinnamon leaf, garlic, lemon eucalyptus, lemongrass, peppermint, citronella Java, and blue raspberry oils, combined with an emulsifying agent and pH conditioning agent like apple cider vinegar, which can be diluted in water for broad application methods, providing effective repellency for up to eight weeks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional chemical insecticides are used, then insect eradication effectiveness is improved, but toxicity to humans, animals, and the environment increases
Solution Approach 1:
The patent changes the chemical composition parameters by replacing synthetic insecticides with natural essential oils (cinnamon leaf, garlic, lemon eucalyptus, lemongrass, peppermint, citronella Java, and blue raspberry oils). This parameter change maintains insect repellent effectiveness while eliminating the harmful toxicity associated with conventional chemical insecticides, directly resolving the contradiction between effectiveness and safety.
Solution Approach 2:
The invention uses a composite formulation combining multiple natural essential oils together with emulsifying agents and pH conditioning agents. This composite approach leverages the synergistic repellent properties of different essential oils while using biodegradable emulsifiers to maintain stability, achieving both effectiveness and environmental safety simultaneously.
2Reliability
If chemical insecticides are used, then insect control effectiveness is improved, but handling and storage complexity increases due to hazardous requirements
Solution Approach 1:
The patent changes the chemical hazard parameters by substituting toxic synthetic chemicals with non-toxic natural essential oils. This parameter change eliminates the need for special hazardous material licenses, permits, and specialized handling equipment, thereby simplifying storage and handling requirements while maintaining insect control effectiveness.
3Object-affected harmful factors
If natural essential oils are used, then safety and non-toxicity are improved, but duration of action decreases
Solution Approach 1:
The patent creates a composite formulation that combines multiple essential oils with different volatility profiles and repellent mechanisms. This composite structure extends the overall duration of action by ensuring that as some oils evaporate or degrade, others remain active, providing continuous protection while maintaining safety.
Solution Approach 2:
The invention introduces emulsifying agents as intermediaries that stabilize the essential oil mixture and control its release rate. These emulsifiers act as mediators between the oil-based repellents and water-based carriers, enabling sustained release of active ingredients over extended periods while maintaining the non-toxic natural composition.
4Ease of operation
If essential oils are combined with emulsifying agents, then ease of application is improved, but formulation complexity increases
Solution Approach 1:
The patent uses emulsifying agents as intermediaries that bridge the incompatible oil and water phases. These emulsifiers simplify application by creating stable, homogeneous formulations that can be easily mixed and applied, while their self-emulsifying properties actually reduce the need for complex mixing equipment or specialized application procedures.

AI summary
A non-toxic insect repellent concentrate formulation utilizing a plurality of all natural active components has been proven to be effective in repelling mosquitoes for periods of between six to eight weeks, with one application. The insect repellent concentrate formulation includes a plurality of natural essential oils comprising at least one emulsifying agent to maintain the oils in a stable solution. A pH conditioning agent may be added to assure the formulation is pH balanced for application to grass, plants, and trees, without detriment. The formulation may be provided as either a concentrate, or at dilutions ready for direct application, and may be applied by any of a variety of methods including broadcast spraying, boom applicators, misting systems, aerosol spray devices, etc.
