Applications

Lubricant Industry

• Trimethylolpropane Oleate plays a crucial role as a synthetic ester base oil in modern lubricant formulations. Its molecular structure, containing multiple ester linkages, provides exceptional lubricity, film strength, and oxidative stability, which ensures consistent performance under high temperature and heavy-load operating conditions. The product demonstrates a high viscosity index, maintaining stable viscosity across a wide temperature range, which is particularly valuable for equipment operating in extreme climates.
• TMPO also exhibits a low pour point and excellent thermal stability, making it suitable for use in a variety of lubricant systems including gear oils, compressor oils, hydraulic fluids, and turbine oils. Its high biodegradability makes it a preferred ingredient for environmentally friendly lubricants that comply with EU Ecolabel and ISO 15380 standards. When blended with polyalphaolefins (PAO) or other esters, TMPO enhances lubricating film strength and reduces friction coefficients, improving energy efficiency and extending equipment service life.

Metalworking and Industrial Fluids

• In the field of metalworking, Trimethylolpropane Oleate is recognized as a high-performance boundary lubricant and oiliness agent. It forms a stable adsorption layer on metal surfaces, reducing direct metal-to-metal contact and minimizing frictional heat. This property not only enhances tool life but also improves the smoothness of finished metal surfaces. TMPO performs effectively under both low-speed and high-pressure conditions, offering outstanding anti-wear and extreme-pressure (EP) characteristics.
• Furthermore, TMPO provides inherent anti-rust and anti-corrosion properties, protecting metallic components during and after machining operations. Its good solubility in various base oils and additive packages allows it to be incorporated into semi-synthetic and full-synthetic cutting oils, stamping fluids, and rolling oils. Compared with traditional mineral-based lubricants, TMPO improves biodegradability and operator safety, making it a key material in sustainable metalworking fluid development.

Polymer and Plasticizer Applications

• Trimethylolpropane Oleate serves as an efficient non-phthalate plasticizer for thermoplastic polymers, elastomers, and coatings. It improves the flexibility, elongation, and processing characteristics of resins such as PVC, polyurethane, and acrylics, while maintaining long-term durability and mechanical integrity. TMPO’s balanced molecular structure prevents migration and volatilization, helping maintain product stability during extended use or high-temperature processing.
• Its biodegradability and non-toxic nature make TMPO a strong alternative to traditional phthalates, aligning with global trends toward safer and more sustainable plasticizers. In flexible cable coatings, sealants, and synthetic leathers, TMPO enhances low-temperature impact resistance and surface smoothness. The product also acts as an internal lubricant that reduces melt viscosity and promotes homogeneous pigment and filler dispersion, improving product gloss and uniformity.

Coatings and Paints

• In coating formulations, Trimethylolpropane Oleate functions as a reactive diluent and film-forming additive that improves flow, gloss, and substrate adhesion. It is particularly compatible with alkyd, epoxy, and polyurethane systems, helping increase the solid content and reduce volatile organic compounds (VOCs). TMPO contributes to superior flexibility and resistance to cracking or yellowing, ensuring long-term film durability and color stability.
• During formulation, TMPO enhances coating rheology and provides a smoother leveling effect, resulting in uniform film appearance. Its lubricity also reduces surface friction, improving scratch resistance and application smoothness. In industrial coatings, it supports excellent resistance to weathering and oxidation, while in decorative coatings, it provides a natural gloss and pleasant tactile feel. These properties make TMPO an ideal component for both high-performance and eco-friendly coating systems.

Cosmetic and Personal Care Industry

• Trimethylolpropane Oleate is an effective emollient and skin-conditioning agent used in skincare, haircare, and cosmetic formulations. Its non-greasy, light texture provides a soft, smooth feel while improving product spreadability and absorption. TMPO forms a delicate, breathable film on the skin surface, enhancing moisture retention without clogging pores. It is widely applied in creams, lotions, sunscreens, and serums, where it improves texture and enhances overall product sensorial quality.
• In haircare applications, TMPO serves as a conditioning and shine-enhancing agent. It smooths the hair cuticle, reduces static, and increases combability, contributing to softer and more manageable hair. Its excellent compatibility with surfactants, waxes, and esters allows formulators to design stable emulsions and lightweight formulations. Because of its biodegradability and natural origin, TMPO meets the growing demand for sustainable and mild cosmetic ingredients favored by international brands.

Emerging and Specialty Applications

• Beyond traditional markets, Trimethylolpropane Oleate has attracted attention in bio-based hydraulic fluids, transformer oils, and specialty greases, where environmental performance and operational stability are both critical. Its high flash point, strong lubricity, and oxidation resistance make it a key candidate for next-generation synthetic fluids.
• In polymer processing, TMPO serves as a processing aid, improving filler dispersion and melt flow properties. It is also being studied for use as a carrier oil in agricultural formulations, promoting better distribution and absorption of active ingredients. With the global emphasis on sustainability, TMPO’s renewable feedstock origin and multifunctional characteristics position it as a versatile material for industries transitioning toward greener and higher-performance products.
