Solution Overview

Problem

There is a need to enhance the antimicrobial effectiveness of plant essential oils by increasing their cellular uptake, as existing compositions may not adequately address microbial infections, particularly in the gastrointestinal tract.

Innovation Solution

A combination of at least two plant essential oils, such as oregano and cinnamon, is used with antimicrobial enhancers like polyethyleneimine or polyphosphate, to create a composition that maximizes antimicrobial activity, which can be further enhanced through microencapsulation for extended gastrointestinal tract coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plant essential oils are used alone, then they have antimicrobial activity and pleasant fragrance, but their cellular uptake and antimicrobial effectiveness are insufficient

Engineering Contradiction:
Improveantimicrobial effectivenessVSAvoidcellular uptake
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent introduces enhancers (polycations, surfactants, or combinations thereof) as intermediary substances that facilitate the uptake of essential oils by microbial cells. These enhancers act as mediators between the essential oil molecules and the bacterial cell membrane, increasing permeability and enabling greater cellular uptake of the antimicrobial agents, thereby resolving the contradiction between maintaining fragrance and improving effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates composite antimicrobial compositions by combining essential oils with enhancers (polycations and/or surfactants). This composite approach allows the mixture to exhibit enhanced antimicrobial activity compared to the essential oils alone, while maintaining the desirable fragrance properties. The composite formulation synergistically combines the antimicrobial essential oils with uptake-enhancing agents.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If essential oils are mixed with carriers for veterinary and human uses, then they gain potential applications in teat dips, skin ulcers, shampoos, and internal use, but their antimicrobial effectiveness remains limited without enhancers

Engineering Contradiction:
Improveapplication rangeVSAvoidantimicrobial effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent develops a universal enhancer system (polycations and surfactants) that can be applied across multiple product types and application areas. The same enhancer classes effectively improve antimicrobial uptake whether the composition is used as a teat dip, skin ulcer treatment, shampoo, or internal GI tract medication. This multi-functional approach allows a single formulation strategy to serve diverse veterinary and human health applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 essential oils with enhancers significantly increases antimicrobial efficacy, effectively treating a range of microbial infections, including those in the GI tract, as demonstrated by testing at Iowa State University, and can be formulated into various veterinary and human use products.

Implementation Method 1

Some researchers have theorized that plant essential oils soften the walls of the bacteria then permeate them thus causing the enhanced anti-bacterial effect

Methodology Applied
Scientific EffectPermeability enhancement: Permeation

Implementation Method 2

plant essential oils, that is oils derived from plants by distillation, expression or extraction may have antimicrobial activity when exposed to bacterial cells

Methodology Applied
Scientific EffectAntimicrobial activity:

AI summary

Antimicrobial compositions based on a combination of plant essential oils of enhanced antimicrobial effectiveness are prepared by adding to the combination of at least two plant essential oils, a small but antimicrobial enhancing effective amount of an enhancer selected from the group consisting of polyionic organic enhancers and polyionic inorganic enhancers. One preferred composition it is a mixture of plant essential oils wherein at least one of the oils is oregano oil.
