These oils are suitable for Pharmaceutical, Cosmetics and Food Industries for Direct & Indirect Food Contact. It is insoluble in water and acids. The degree of strain rate dependence (shear thinning) also decreases with increasing paraffin oil content. The exception is the pure paraffin oil, which displays a linear relationship between shear strain rate and shear stress and a constant value of viscosity, indicative of Newtonian behaviour.

When the paraffin content gets saturated in the crude oil, the paraffin crystals start forming and depositing on the tubular surfaces, aggregating, getting thick, may cause paraffin stuck in the producer. OSDTM is a type of solvent containing wax-philic group and wax-phobic group in an organic dispersant.

All mixtures have yield stress and flow stress (strain softening) values that decrease with decreasing shear rate, and with increasing relative amounts of paraffin oil. We present new rheological tests of petrolatum–paraffin oil mixtures. In this paper, we present rheological tests of petrolatum, paraffin oil and several homogeneous mixtures of the two. 0 All the other mixtures are non-Newtonian with stress exponents n between 3.3 and 7.5 ( Table 3 ).

Kinematic Viscosity The ratio of the absolute viscosity of a liquid to its density frequently occurs in the study of viscosity and hydraulics and the term "kinematic viscosity" with the symbol V has been assigned to it where p is the density.
