Base Oils

Based on new Secondary Polyol Ester ™ technology, VBASE base oils provide exceptional hydrolytic stability, efficiency, and compatibility to enable the formulation of high-performance Environmentally Acceptable Lubricants (EALs).

This new class of synthetic esters surpasses the performance of both mineral base oils and traditional synthetic ester base oils. VBASE® is available across a range of viscosity grades (ISO 32-460) and provides compatibility with all major base oils and seals, easy formulation, and excellent solvency.

Esters have long been known to provide high VI and high shear stability leading to more efficient operation of fluid power systems. Due to their molecular structure, VBASE® lubricants may provide reductions in viscous drag generating efficiency gains beyond those noted in common ester fluids. VBASE base oils provide enhanced lubrication and performance across boundary, mixed, and hydrodynamic lubrication regimes.

With a novel molecular structure, VBASE® lubricants provide enhanced thermo-oxidative and hydrolytic stability compared to other Group V base oils. VBASE base oils achieve higher viscosity grades (ISO VG 32-100) without utilizing complex esters or viscosity modifiers and maintain cold temperature stability with saturated fatty acid components, further bolstering their in-service stability.

VBASE® lubricants are compatible with most conventional lubricants enabling seamless change over. As synthetic esters, VBASE™ lubricants have high solubilizing power for polar contaminants and additives without phase separation. VBASE lubricants show good seal and paint compatibility (John Deere Fluid Resistance Testing and Caterpillar Fluid Immersion Resistance Testing). With superior compatibility, VBASE lubricants can be used as a performance boosting compatibilizer/additive or utilized in a stand-alone formulation like VBASE™ Hydro T-EL. 

Designed for performance first, all VBASE® products are environmentally acceptable lubricants and suitable for use in many environmentally sensitive areas such as hydropower plants, agricultural, forestry, and marine environments. VBASE lubricants have high inclusion of renewable carbon (>50%), are biodegradable (>60% by OECD 301B), non-toxic, and do not bioaccumulate.

VBASE® lubricants are high performance, environmentally acceptable fluids that deliver renewable solutions without trade-offs in performance, price, or availability. VBASE lubricants are available in drum, tote, and bulk quantities.

  • Service to Formulators

    We understand developing a lubricant with a new base oil is a commitment on our customers' part and we are prepared to meet that commitment with a high level of technical support by providing testing and characterization.


    Reach out for samples and support to bring your formulation to market.


Tiarco Chemical is experienced in formulating lubricants with VBASE base oils.

Tiarco Chemical, a subsidiary of Textile Rubber & Chemical Co., Inc. was established in 1973. Since that time, our primary goal has been to develop and continually deliver specialty chemicals designed to provide the highest levels of cost performance in grease and lubricants, natural and synthetic latices, water treatment, and oil & gas applications.

Lubricant formulators interested in working with VBASE base oils should contact us.

Sustainability and Circular Economy
The desire for sustainable solutions for companies in every industry has never been greater, but sustainability is about more than just being safe for our environment. By developing VBASE® oils with improved efficiency and greater stability, oil lifetimes are extended and waste reduced. Sustainable oils also reduce fuel consumption and emissions by increasing overall equipment efficiency. At the end of oil life, VBASE® plans to work with our customers to bring used oil back for reconditioning, repurposing, or remanufacturing. Work to develop methods to maximize reused content in remanufactured oils is ongoing.

As VBASE® grows, it is our goal to develop a supply chain that minimizes environmental impacts of transportation and distribution while maximizing positive effects on local economies by manufacturing in region and sourcing local natural feedstocks.

VBASE Base Oils Enable Environmentally Acceptable Lubricants
VBASE® produces oils that deliver the highest performance and greatest energy savings without compromising our environment. This new family of products enables the use of environmentally acceptable lubricants (EALs) in many environmentally sensitive areas such as hydropower plants, agricultural & forestry equipment, and marine environments.

VBASE® base oils are biobased (inclusion of renewable carbon >50%), are readily biodegradable (>60% by OECD 301B), non-toxic (OECD 201, OECD 202, OECD 203, OECD 236), and non-bioaccumulating (OECD 117).

In addition, VBASE base oils are NSF HX-1 and thus suitable for formulation of H1 lubricants for use in and around food processing areas. VBASE 68SLV has been certified EU Ecolabel LuSC List and other base oil certifications are anticipated in the coming months.

Formulated Lubricants

Base oil performance must be demonstrated in a fully formulated lubricant. To that end, the VBASE® team designed Hydro T-EL™, a fully formulated lubricant developed to have the performance characteristics of a traditional Hydropower Turbine oil while eliminating the risk of contamination of public waterways. VBASE® HF-AW (Hydraulic Fluid/Anti-Wear) and VBASE® ECO-UTF are in development.
