Release agents are compounds usually sprayed on the molds surface, forming a thin film that can act as a barrier preventing the sticking. Herein, both physical and chemical optimization of a wax-based O/W emulsion for polyurethane (PU) foams is reported. E_N_1.8Cet_1.2Ac_2.5 sample (where N, Cet and Ac stand for the percentages of linear amine, cetyl alcohol and acetic acid), emulsified by the inversion point method, turned out to have the optimal composition, in terms of smaller oil droplets size (by Dynamic Light Scattering analysis and optical measurements), long-term stability (by Abbe refractometer and backscattering tests), good spreading (contact angle and surface tension measurements) and low corrosion phenomena (by potentiodynamic polarization tests, Scanning Electron Microscopy analysis). Principal Component Analysis helped to find the best correlations among all the investigated variables and to have some predictions on the role of the different raw materials in affecting the final stability of the emulsions.

脱模剂是通常喷在模具表面上的化合物，形成可以充当防止粘连的屏障的薄膜。在此，报道了用于聚氨酯（PU）泡沫的基于蜡的O / W乳液的物理和化学优化。E_N _1.8焦耳_1.2交流_2.5通过反转点法乳化的样品（其中N，Cet和Ac代表线性胺，鲸蜡醇和乙酸的百分比），以较小的油滴尺寸（通过动态光散射）证明具有最佳的成分分析和光学测量），长期稳定性（通过阿贝折射仪和反向散射测试），良好的扩展性（接触角和表面张力测量）和低腐蚀现象（通过电动力极化测试，扫描电子显微镜分析）。主成分分析有助于找到所有研究变量之间的最佳相关性，并对不同原材料在影响乳液最终稳定性中的作用做出一些预测。
