PROCESSO PARA A PRODUÇÃO DE ISOOLEATO DE ETILA E FÓRMULAS APLICADAS EM PRODUTOS COSMÉTICOS

Abstract

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.

Description

The present invention is based on the development of ethyl isooleate obtained from the isomerization of fatty 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. 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.

RELATED CURRENT TECHNOLOGY

There are few applications for ethyl isooleate due to the fact that isooleic acid is still a co-product of the isomerization process of unsaturated fatty acids.

Technologies for its direct production using zeolite-based catalysts are being developed and in the future the production volumes of isooleic acid will increase due to its superior properties, compared to oleic acid.

Consequently, applications are concentrated on ethyl oleate that is used as a lubricating agent with the function of extending the life of car and truck engines.

Ethyl oleate has wide application in the food and cosmetics industries, it can also be used as a solvent in the pharmaceutical industry, as a lubricant, as a plasticizer, in the production of biodiesel or as an additive in diesel oil.

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.

The petroleum oil market in the United States was estimated at US$436.5 million per year in 2021, which corresponds to 25.86% of the global market which is equivalent to US$1.687 billion per year.

The most used raw material currently is palm oil due to the growth in its cultivation.

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.

BRIEF DESCRIPTION OF THE FIGURE

FIG. 1 shows a schematic view of the production of ethyl isooleate.

DESCRIPTION OF THE INVENTION

The production of ethyl isooleate shown in the diagram in FIG. 1 shows that it is 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 at temperatures between 250° C. and 280° C.

In this initial step, oleic acid can be replaced by linoleic acid.

At this stage, zeolites can also be compensated by montmorrillonites in the same temperature variation.

The isooleic acid obtained is then combined with ethanol, resulting in ethyl isooleate.

The product obtained has been tested in accordance with the following cosmetic formulae, and complete application tests have been carried out to guarantee its safe use:
