Ethyl Isooleate Production via Zeolite Catalyzed Isomerization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current applications of ethyl isooleate are limited due to the co-production of isooleic acid during the isomerization of unsaturated fatty acids, and there is a need for a lubricating agent with superior properties compared to ethyl oleate.
Innovation Solution
The production of ethyl isooleate through the isomerization of fatty acids from soy, palm, sunflower, rapeseed, and peanut, using zeolites as catalysts, which results in non-linear branched chains with enhanced emollience, lubricity, and stability, making it suitable for cosmetic formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ethyl oleate is used as a lubricating agent, then it provides basic lubrication function, but it lacks superior emollience and stability compared to ethyl isooleate
Solution Approach 1:
The patent applies parameter changes by transforming oleic acid into isooleic acid through isomerization process, changing the molecular structure from linear to branched configuration. This structural parameter change results in ethyl isooleate having superior emollience, lubricity, and stability properties compared to ethyl oleate, while maintaining compatibility with existing cosmetic formulations.
2Productivity
If isooleic acid is produced as a co-product of isomerization, then production volumes increase, but applications remain concentrated on ethyl oleate due to limited knowledge of isooleate properties
Solution Approach 1:
The patent creates new application formulations using ethyl isooleate as a substitute for ethyl oleate in cosmetic products. By developing specific formulation examples (face creams, body creams, hair conditioners with defined compositions), the patent demonstrates the versatility and adaptability of ethyl isooleate, expanding its application range beyond the traditional limited uses.
3Reliability
If ethyl oleate is used in cosmetic formulations, then it serves as an excipient for active ingredient delivery, but it lacks the superior emollience and solvency properties of ethyl isooleate
Solution Approach 1:
The patent utilizes parameter changes in the molecular structure by replacing ethyl oleate with ethyl isooleate, which has a branched chain structure instead of linear. This structural parameter change provides superior emollience, lubricity, and solvency properties, enhancing the performance of cosmetic formulations without requiring complex additional components.
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
Ethyl isooleate demonstrates superior properties over ethyl oleate, including greater emollience, lubricity, solvency, and stability, making it an effective ingredient in cosmetic formulations such as face creams, body creams, and hair conditioners without causing skin or ocular irritation.
Implementation Method 1
the transformation of oleic acid into isooleate, through the isomerization process, where it is initially transformed into isooleic acid from the combination with zeolites, which acts as a catalyst
Implementation Method 2
Isomerization creates non-linear branched chains that generate unique properties such as greater emollience, lubricity, solvency, spreadability, thermal and chemical stability

AI summary
The development of ethyl isooleate obtained from the isomerization of fatty acids from soy, palm, sunflower, rapeseed, peanut and its applications in the cosmetic field, more specifically, in formulations of face creams, body creams and hair conditioners is described. Isomerization creates non-linear branched chains that generate unique properties such as greater emollience, lubricity, solvency, spreadability, thermal and chemical stability, as well as greater fluidity in viscous systems. Ethyl isooleate is free from ocular and skin irritation, being completely non-allergenic. Ethyl oleate is an excellent solvent for active ingredients in ointments, creams, lotions. It works as an excellent excipient in delivery system formulations, helping the penetration of active ingredients into the skin. All of these characteristics above belong to ethyl oleate, however, from a physicochemical point of view, ethyl isooleate has superior properties to its isomer ethyl oleate.
