Rheological Characterisation of a Carbopol Microgel and a Commercial Body Lotion: Steady, Oscillatory, and Parallel Superposition Measurements

This dataset comprises rheological measurements of two viscoplastic materials: (i) a neutralised Carbopol microgel prepared at 2 g/L concentration (Ultrez-21, Lubrizol), and (ii) a commercial emulsion (Dove Essential Care Body Lotion, Unilever). The dataset includes raw data from steady shear rheometry, oscillatory shear tests (frequency and strain amplitude sweeps), and parallel superposition of stresses measurements.All tests were conducted using an MCR 302 rheometer (Anton Paar) using a roughened parallel-plate geometry (PP50/P2, Anton Paar) at a controlled temperature of 25 °C.The parallel superposition tests were performed for a stress signal sigma(t) = sigma0 + epsilon * sin(omega * t) where sigma0 is the stress offset, epsilon the amplitude of the oscillatory component and omega the frequency.

本数据集包含两种粘塑性材料的流变学测试数据：(i) 浓度为2 g/L的中和型卡波姆（Carbopol）微凝胶（Ultrez-21，路博润（Lubrizol））；(ii) 市售乳液——多芬（Dove）滋养护理身体乳，联合利华（Unilever）出品。本数据集涵盖稳态剪切流变测试、振荡剪切测试（含频率扫描与应变振幅扫描）以及应力平行叠加测试的原始数据。所有测试均采用安东帕（Anton Paar）MCR 302流变仪完成，搭配带粗糙表面的平行板夹具（PP50/P2，安东帕（Anton Paar）），并将测试温度精准控制在25 ℃。本次应力平行叠加测试所采用的应力信号为σ(t) = σ₀ + ε·sin(ωt)，其中σ₀为应力偏置量，ε为振荡分量的幅值，ω为角频率。
