皂基皮肤清洁剂的泡沫形态及其对皮肤渗透性的影响

现今,对皮肤刺激小的清洁剂备受关注。本文利用液相色谱/质谱技术,从表面活性剂渗透的角度,研究泡沫特征与皮肤刺激性之间的关系。结果显示,随着泡沫析出液中表面活性剂浓度的降低,析出液中长链表面活性剂的含量降低,而此时泡沫的体积在逐渐变小。当皮肤上与泡沫接触时,泡沫的排水量决定了表面活性剂渗入皮肤的量,表面活性剂渗入到皮肤的量随泡沫体积的增大而增加。这是由于气/液界面的表面活性剂不能自由移动,因而泡沫析水液中的表面活性剂易于渗入皮肤。结果说明,在设计皮肤清洁剂配方时,表面活性剂种类、泡沫形态以及产生泡沫的方式都是应该考虑到的重要因素。     

Application of Ceramic Membranes for Regeneration of Detergent Cleaning Solutions

Pressure-driven membrane processes were investigated for the recovery of contaminated cleaning solutions （a single-phase detergent） emanating from a diary industry. The experiments were performed in a semi-pilot membrane installation in cross-flow regime. The filtration tests were carded out using tubular ceramic modules differing in cut-offvalue, with high resistance to chemical agents. The effect of long term filtration time and process conditions （transmembrane pressure, cross-flow velocity and temperature） on transport and separation properties of the modules was evaluated. The usefulness of ceramic modules for regeneration of a single-phase detergent for the purpose of its reuse in cleaning systems was revealed. The modules in a long-term filtration regime, due to their hydrophilic nature, were characterized by relatively low susceptibility to fouling. Rinsing modules with deionized water after filtration experiments helped significantly to restore their original permeability or cause even an increase of water flux in comparison with the stream of deionized water. The recovered spent detergent maintained its basic cleaning properties, i.e., high pH, high concentration of NaOH and low value of surface tension. Moreover, the ceramic modules showed high retention of specific milk components （protein and lactose） and organic matter expressed as chemical oxygen demand （COD）. It has been shown that the transport and separation properties of the modules were dependent on the process parameters, such as transmembrane pressure, cross-flow velocity and temperature.
