mucilage

sodium methyl cellulose

All the above

Explanation:
Detailed explanation-1: -Pseudoplastic flow exhibits the behavior of both Newtonian flow and plastic flow. In the process of pseudoplastic flow, the liquid tends to flow as plastic at high shear rates. However, it does not have a yield point, and therefore, it will always flow under the shear stress similar to a Newtonian liquid.
Detailed explanation-2: -In rheology, shear thinning is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain. It is sometimes considered synonymous for pseudo-plastic behaviour, and is usually defined as excluding time-dependent effects, such as thixotropy.
