Behind food, cosmetics, pharmaceuticals, and even plastic products lies a low-key “all‑rounder”— Glyceryl monooleate As a leading example of green chemistry, this compound derived from natural oils is quietly reshaping the landscape of modern industry.

Precision architecture at the molecular level

Glyceryl monooleate (GMO) has a molecular structure that resembles an intricate “chemical building block.” It consists of two core components: a glycerol molecule (propane‑1,2,3‑triol) serving as the backbone, which is esterified to a single oleic acid molecule (octadecenoic acid). This structure belongs to the monoglyceride family, clearly distinct from diglycerides—containing two oleic acid chains—and triglycerides—containing three oleic acid chains.

Depending on the levels of total monoacylglycerols and free glycerol, products on the market are typically classified as GMO40 and GMO90. They appear as milky white or pale yellow liquids or pastes, with an HLB value of 3.5–4.0, and are readily soluble in oils and fats while dispersible in water.

From a chemical perspective, its molecule consists of three elements: carbon, hydrogen, and oxygen. Carbon forms the molecule’s basic backbone, hydrogen imparts appropriate flexibility and hydrophobicity, while oxygen links glycerol and oleic acid tightly via ester bonds. This distinctive structure endows glyceryl monoolate with both hydrophilic and lipophilic properties—precisely the secret behind its effectiveness as an emulsifier.

It is reassuring that the safety of glycerol monooleate has been recognized by leading global authorities. The U.S. FDA has listed it on its GRAS (Generally Recognized As Safe) roster, the Cosmetic Ingredient Review (CIR) Expert Panel has confirmed its safety for use in cosmetics, and the Food and Agriculture Organization/World Health Organization (FAO/WHO) has not established a daily intake limit for it.

The pinnacle of green technology

The production process of glycerol monooleate has undergone a leap‑forward evolution, transitioning from conventional methods to innovative ones. At present, the industry primarily employs three distinct production approaches:

Traditional esterification method It is one of the earlier processes, which involves the reaction of fatty acids and glycerol in the presence of a catalyst. While this method is well‑established, it suffers from long reaction times and limited product purity.

Enzymatic catalysis method This signifies the industry’s direction toward green innovation. By employing specific enzymes as catalysts, efficient conversions can be achieved under mild conditions, offering high selectivity and minimal by‑product formation. However, the initial challenge of relatively high enzyme costs has been gradually addressed through technological advances.

Supercritical fluid method This represents a more advanced technology that leverages the unique properties of fluids in the supercritical state to achieve highly efficient esterification, yielding products of exceptionally high purity; however, it also places higher demands on equipment.

Jiadele has achieved technological breakthroughs in this field, collaborating with universities such as Jinan University and South China University of Technology to jointly develop… “The large-scale, continuous, green manufacturing technology for high-purity fatty acid glycerides” has reached an internationally leading level. This technology employs a solvent-free or green-solvent system, achieving zero discharge of wastewater, exhaust gases, and solid waste, while reducing energy consumption by approximately 20% compared with conventional processes. Moreover, a four-stage molecular distillation purification process elevates the purity of glycerol monooleate from 99.2% to over 99.8%.

Standard for the Determination of Monoolein

A versatile all-rounder for cross-industry applications

Glycerol monostearate, with its outstanding emulsifying, stabilizing, and thickening properties, has demonstrated remarkable performance across a wide range of applications:

Food industry It is its primary application scenario. Monoolein, through a fourfold mechanism—interfacial emulsification, starch complexation, crystallization control, and foam stabilization—comprehensively enhances food texture, shelf life, and processability, while also offering health benefits (containing the essential fatty acids linoleic acid and alpha-linolenic acid).

Emulsification: stabilizing the oil–water interface

Reduce interfacial tension: They are oriented at the oil–water interface, forming stable micelles that prevent the separation of the oil and water phases. For example, they inhibit oil flotation and protein sedimentation in beverages.

Enhance uniformity: When used in ice cream and whipped cream, it promotes the fine dispersion of fat, prevents the formation of ice crystals, and maintains a smooth, creamy texture.

Anti-starch retrogradation: delays food hardening.

It exerts its function by specifically binding to starch molecules:

Complexed linear amylose: It is incorporated into the starch helical structure, inhibiting starch molecular recrystallization (staling) and extending the softness and shelf life of bread and cakes. An addition level of 0.3%–0.8% (based on flour weight) can significantly enhance dough extensibility.

Regulating lipid crystallization: optimizing textural stability

Directed regulation of crystallization behavior in lipid-containing foods:

Inhibition of crystal coarsening: In chocolate and margarine, it adsorbs onto the surface of fat crystals, delaying the formation of β‑type crystals and preventing bloom (fat separation) and textural hardening.

Improve plasticity: Enhances the spreadability of fats, making baked goods easier to handle.

Foam Stability and Functional Enhancement

Foam-stabilizing effect: In cake production (at an addition level of 3%–10%), it reduces the surface tension of egg mixtures, enhances egg white foaming and stabilizes the air‑bubble structure, thereby increasing product volume.

Nutrient carrier function: As a solvent carrier for fat-soluble vitamins (such as vitamins A and D) and pigments, it enhances their dispersibility and bioavailability in food.

Cosmetics industry Among them, glycerol monooleate serves as both an emulsifier and an emollient, widely used in products such as facial creams, lotions, and lip balms. It helps achieve uniform dispersion of oil and water phases, enhancing product stability while delivering a smooth, silky feel upon application. Its excellent skin compatibility has been confirmed through numerous safety assessments.

Pharmaceutical field In this context, it can serve as a drug carrier or solubilizing agent, enhancing the bioavailability and therapeutic efficacy of drugs, and is commonly used in the formulation of creams, ointments, and other dosage forms.

Industrial Applications In addition, glycerol monooleate is used in the textile industry as a fabric finishing agent, in plastic processing as an internal antistatic agent (typically at 0.5–2.0%), and also as a pigment‑grinding additive, among other applications.

Gadel’s monoglyceride of oleic acid boasts several key advantages:

Strong technical capabilities. As a nationally recognized “Little Giant” enterprise specializing in niche, specialized, and innovative fields, Jiadele has been deeply engaged in ester‑based materials for 20 years.

The product quality is excellent. By means of a self-developed curved-plate distillation unit, heat-exchange system, vacuum system, and online monitoring system, stable product purity exceeding 99.8% has been achieved, significantly surpassing the industry average.

Practicing the concept of green production. By employing an efficient preparation process based on solvent-free or green-solvent systems, the facility achieves zero discharge of wastewater, exhaust gases, and waste materials, while reducing energy consumption by approximately 20% compared with conventional methods, thus realizing truly environmentally friendly and sustainable production. In 2024, it was recognized by the Ministry of Industry and Information Technology as a “National Green Factory.”

Leading production capacity. An intelligent, continuous production line for high-purity fatty acid glycerides—boasting the world’s largest single‑line capacity of 100,000 tons per year—has been commissioned, equipped with an industrial Internet platform to enable large-scale, digitalized, networked collaboration, as well as smart and green manufacturing.
