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.

VBASE® Sales and Application Support

We work closely with blenders and formulators to harness the enhanced performance of VBASE® base oils in their environmentally acceptable lubricants. When provided with samples of your current formulated oil, we will work with you to validate compatibility to ensure a smooth transition.

  • 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.

VBASE Base Oils Enable Environmentally Acceptable Lubricants

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.
