Provided herein are thickened compositions produced upon assembling a first sub-formulation having a hydroxide, and at least one second sub -formulation having an alkaline material, wherein at least one sub-formulation is thickened by lightly-to moderately-crosslinked PVP. Unlike other compositions not having the lightly-to moderately-crosslinked PVP, those described herein maintain or even build viscosity when the first and second sub -formulations are blended. The compositions may be utilized in the formulation of personal care and performance chemicals, such as hair relaxers, hair straighteners, depilators, degreasers, paint strippers, and cleaners. Methods for enhancing product handling and performance are also described.
