Oleochemicals and their applications: a sustainable future

Oleochemicals, derived from natural fats and oils, are gaining traction as sustainable alternatives to petrochemicals. These versatile compounds are used across various industries, from personal care to agriculture, offering eco-friendly solutions. This article explores the production, applications, and environmental impact of oleochemicals, supported by recent studies and industry reports.

What Are Oleochemicals?

Oleochemicals are chemical compounds that are obtained from fats and oils, both vegetable and animal, such as palm oil, coconut oil, soybean oil, and animal fats like tallow. They are defined as a class of aliphatic compounds. The primary types of oleochemicals include fatty acids, fatty alcohols, methyl esters, and glycerin.

Oleochemicals are renewable and sustainable, which makes them an eco-friendly substitute for petrochemicals. They are also biodegradable and decompose in the environment without causing pollution. Oleochemicals are part of the formulation in a variety of daily-used products like detergents, soaps, cosmetics, pharmaceuticals and candles. But they can also be used in lubricants, additives for plastics, textiles, food and many others.

Applications of Oleochemicals

Personal care and cosmetics:

Oleochemicals are extensively used in the personal care and cosmetics and personal care industry. They act as emulsifiers, surfactants, and emollients, providing texture, foaming properties, and moisturizing benefits. Additionally, oleochemicals are less likely to irritate the skin compared to synthetic alternatives. Products like soaps, shampoos, lotions, and creams rely on oleochemical derivatives for their effectiveness.

Detergents and cleaning agents:

In household and industrial cleaning, oleochemicals play a crucial role as surfactants. Fatty alcohol sulfates and fatty acid soaps help break down oils and grease, ensuring effective cleaning.

Food industry:

Oleochemicals are used in the food industry as additives, emulsifiers, and stabilizers. Mono- and diglycerides enhance the texture and shelf-life of processed foods. They are also employed in biodegradable food packaging materials, contributing to sustainability.

Pharmaceuticals:

In pharmaceuticals, oleochemicals serve as excipients and active ingredients. Glycerin, a byproduct of oleochemical production, is used as a humectant, solvent, and sweetener in medications. Fatty acids and their derivatives improve the efficacy and stability of active pharmaceutical ingredients. They are used as excipients in drug formulations, lubricants in tablet manufacturing, and base materials for topical ointments and creams.

Agriculture:

Oleochemicals contribute to the formulation of bio-based pesticides, herbicides, and fertilizers. These eco-friendly alternatives reduce dependency on synthetic chemicals, promoting sustainable farming practices. Fatty acids and glycerin are used as adjuvants, enhancing the effectiveness of agricultural chemicals.

Industrial applications:

Oleochemicals are used in the production of lubricants, greases, and metalworking fluids. Oleochemical-derived plasticizers and adhesives are important components in manufacturing plastics and composites.

Oleochemicals act as polymers additives, they enhance or modify the properties, processing, and performance levels of polymers, these additives can improve mechanical strength, thermal stability, UV resistance, flexibility, color, and other characteristics of different applications.

Glycerine:

Glycerine was once produced synthetically. Today, it comes from the natural resources of animal or vegetable oils or fats. It is derived via hydrolysis (saponification) and by reaction with acid and alcohol (transesterification). Several hundreds of applications rely on crude or refined glycerine feedstocks. They range from food, medicine and personal care to detergents, solvents and plastics.

Conclusion and future trends:

The distribution of oleochemical products is very capillary and is related to a multiplicity of uses in all the markets related to food, personal care, cosmetics, pharmaceuticals, medical, paint, resins, emulsifiers, plasticizers, and many others. The oleochemical market has been continuously expanding over the last century and is foreseeable that it will continue to grow, being strictly related to population growth and to the modification of people’s habits to be more inclined to use products.
