Antiseptic Skin Composition via Synergistic Essential Oil Blends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skin preparation compositions for external use often rely on antiseptic chemicals that cause toxicity, skin irritations, and allergies, and alternative methods using diols can affect skin safety and stability, while also being economically inefficient.
Innovation Solution
A skin preparation composition combining glyceryl undecylenate with ethylhexylglycerin, glyceryl caprylate, p-anisic acid, or a citrus mixed extract to achieve enhanced antiseptic ability without using conventional antiseptic chemicals, thereby providing equivalent or greater antimicrobial protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antiseptic chemicals (parabens, imidazolidinyl urea, phenoxy ethanol, etc.) are used to suppress microbe proliferation, then antiseptic ability is improved, but skin irritations, allergies, and toxicity occur
Solution Approach 1:
The patent changes the chemical parameters by replacing conventional antiseptic chemicals with a novel composition containing 0.01-5% polyethylene glycol monoleate and 0.1-5% essential oils. This parameter substitution maintains antiseptic effectiveness while eliminating the harmful side effects of traditional antiseptics such as skin irritations and allergies.
Solution Approach 2:
The patent creates a composite antiseptic system by combining polyethylene glycol monoleate with specific essential oils (tea tree oil, eucalyptus oil, peppermint oil, or thyme oil). This composite formulation achieves synergistic antiseptic effects while avoiding the adverse reactions associated with single conventional antiseptic chemicals.
2Reliability
If diols are used as alternatives to antiseptic chemicals, then antiseptic ability is maintained, but skin safety and emulsion stability are compromised
Solution Approach 1:
The patent substitutes diols with polyethylene glycol monoleate as the primary antiseptic agent. This parameter change maintains antiseptic functionality while improving emulsion stability and skin safety, as polyethylene glycol monoleate is a well-established emulsifier that does not compromise formulation stability.
Solution Approach 2:
The patent introduces essential oils as intermediary substances that enhance the antiseptic effect of polyethylene glycol monoleate. These essential oils work synergistically to provide broad-spectrum antimicrobial activity without the stability issues associated with diol-based systems.
3Reliability
If containers designed to prevent microbe introduction are used, then contamination is reduced, but preparation complexity and facility maintenance costs increase
Solution Approach 1:
The patent makes the composition itself self-protecting by incorporating potent antiseptic ingredients (polyethylene glycol monoleate combined with essential oils) that actively prevent microbial contamination. This eliminates the need for complex external containment systems, as the product inherently resists contamination throughout its shelf life.
Solution Approach 2:
The patent applies preliminary antiseptic action by incorporating antimicrobial agents directly into the composition during manufacturing. This preliminary protection ensures that any potential contaminants are inhibited from the outset, eliminating the need for elaborate post-manufacturing containment measures.

AI summary
The present invention relates to a skin preparation composition for external use having excellent antiseptic ability without using chemical antiseptics. More particularly, the present invention relates to a skin preparation composition for external use, comprising: glyceryl undecylenate having excellent antiseptic ability; and one or more mixtures of ethylhexylglycerin, glyceryl caprylate, p-anisic acid and a citrus mixed extract, thus improving antiseptic ability through the increased effects of antiseptic abilities of those materials.
