Abstract

More than 10 million tonnes of metal salts of fatty acids are manufactured worldwide every year, to create a range of soft condensed-matter cosmetic products such as bar soaps, liquid washes, deodorant sticks, skin creams, toothpastes, and so on. These salts, popularly known as soaps, mainly use palm or tallow-based oils as the source of fatty acids. Soap bars comprised of more than 80% soaps alone account for a significant part of the global oil/fat footprint in non-edible usage. The COVID pandemic highlighted the need for hygiene and germ protection, thereby driving the consumption of soap bars further. Providing these personal hygiene assets to all strata of society while minimizing the negative impact on the environment through increased material consumption is a critical challenge faced by the soap industry today. Considerable research is ongoing toward making more sustainable soap bars by reducing the use of oils/fats without compromising the sensory and functional performance. Another challenge faced is that in many geographies, soap bars must comply with regulatory standards which mandate minimum levels of oils/fats (called TFM—total fatty matter) in the product with no reference to the performance or benefits provided. What this paper will demonstrate is that there are technologies to manufacture soap bars that meet the desired product performance independent of the level of TFM. These technologies have the potential to provide formulation flexibility and environmental benefits by opening the ingredient space and cutting down significantly on greenhouse gas emissions through reduced consumption of oils.

重新审视总脂肪物质在皂条中的作用
超过10 全球每年生产数百万吨脂肪酸金属盐,用于生产一系列软质浓缩物化妆品,如条形皂、液体洗涤剂、除臭剂棒、护肤霜、牙膏等。这些盐通常被称为肥皂,主要使用棕榈油或牛油油作为脂肪酸的来源。仅由80%以上肥皂组成的皂条就占全球非食用油脂足迹的很大一部分。新冠肺炎疫情凸显了卫生和细菌保护的必要性,从而进一步推动了肥皂条的消费。向社会各阶层提供这些个人卫生资产,同时通过增加材料消耗最大限度地减少对环境的负面影响,是当今肥皂行业面临的一项重大挑战。目前正在进行大量研究,通过减少油脂的使用,在不影响感官和功能性能的情况下,制作更可持续的肥皂条。面临的另一个挑战是,在许多地区,皂条必须遵守监管标准,该标准要求产品中的油/脂肪(称为TFM——总脂肪物质)达到最低水平,而不考虑所提供的性能或益处。本文将展示的是,有一些技术可以制造出满足所需产品性能的皂条,而与TFM水平无关。这些技术有可能通过开放成分空间和通过减少油的消耗来大幅减少温室气体排放,从而提供配方灵活性和环境效益。
