洗发香波的配制及其粘度测定

摘要:根据配方的不同,香波可分为多种,本实验的配方为温和性配方,并具有泡沫丰富、对皮肤损伤小等特点,主要是利用主/辅表面活性剂进行香波的增稠、润湿,并通过实验室中粘度的测定来确定原料的加入量,使其达到最优效果。

香波是英文shampoo的音译。据说,香波一词原系印度语,是“按摩”的意思。在国内俗称洗发精,据香波的特征,除了用来清除头发和头皮上积聚的皮脂、皮屑、灰尘以及发用制品的残污物以外,还需要使头发松软、爽洁、有光泽以及易梳理等功能。另外香波在使用时还需要在揉搓头发时产生丰富的泡沫,使使用者在洗发时产生一种将头发洗得很干净的心理上的愉悦感,同时泡沫对头发和头皮之间有润湿作用,所以香波的配方一直不断改进,出现了许多不同类型的品种,本配方具有高泡性、温和性等特点,用本品洗发后发质光泽、容易梳理。

1 实验

1.1 主要试剂

羧甲基纤维素,又名CMC,分子式[C6H7O2(OH)2CH2COONa]n,外观为白色絮状纤维粉末;十二烷基硫酸钠(SDS),白色结晶粉末,熔点67~70°C;椰油基二乙醇胺(Ninol),浅黄色粘稠液体;香精;去离子水。

1.2 仪器

NDJ-5s型数显粘度计(上海精科);万用电炉(上海树立仪器仪表有限公司);电子天平(北京赛多利斯仪器系统有限公司)。

1.3 洗发香波的配制

将75mL去离子水、CMC混合加热至70°C左右使其溶解,在缓缓搅拌下依次加入十二烷基硫酸钠、Ninol,当温度降至45°C时加入适量香精,搅拌均匀即可。

2 结果与讨论

2.1 CMC加入量对香波粘度值的影响

CMC易溶于冷水形成胶状,其重要特性是形成高粘度的胶体、溶液,有粘着、增稠、流动、保护胶体、耐酸、悬浊等特性,因此在本实验中选用CMC作为原料。当SDS、Ninol的质量分别为15g、8g时,改变CMC的质量,依次为1g、1.2g、1.4g、1.6g、1.8g、2.0g,每次溶液溶解均匀后,用数显粘度计测其粘度值。结果如图1所示。

图1粘度值随CMC加入量变化曲线

从图中可看出,随着CMC质量的增多,香波的粘度值逐渐升高,在CMC质量为1.8g时,粘度值达到最高为3972mPa·s,但当CMC质量进一步增加时,粘度值反而下降,说明CMC的最佳加入量为1.8g。

2.2 Ninol加入量对香波粘度值的影响

在香波的配制时需使用表面活性剂,本实验分为主/辅表面活性剂,其中的主表面活性剂为阴离子表面活性剂SDS,但由于阴离子表面活性剂清洁力十分好,脱脂力很强,过度使用会损伤头发,婴儿香波更不可用,因此需要配入辅助表面活性剂,本实验采用非离子表面活性剂Ninol,其具有能溶于水、并大幅度降低水的表面张力等特性,而且耐硬水、泡沫丰富、稳定、去污力强、无毒、不损伤皮肤。实验的反应条件为SDS15g、CMC选择其质量为1.8g,Ninol加入量依次为2g、4g、6g、8g、10g、12g,每次结束测其粘度值。结果如图二。
