The stability and safety of a product is at the very heart of a business: does the product exhibit the characteristics and behaviour desired or advertized. Wild Orchid Farm is a small rural business in goat breeding which has branched out into manufacturing and selling natural cosmetics made from goat dairy products. They have recently formulated a new product, goat's milk body lotion, of great interest to their consumers, but with one huge drawback: the preservative blend they are using, is formaldehyde-releasing, unacceptable in the field of natural cosmetics with very low consumer acceptance. Natural products with a high concentration of milk, such as made by Wild Orchid Farm, requires special care and testing, as milk is an excellent nutritional source for microbes. The preservative used by Wild Orchid Farm is Liquid Germall Plus, a convenient, which inhibits the growth of both gram-positive and -negative bacteria, yeasts, and moulds. However, one of ts components releases formaldehyde and another was described as "Suspected to be an environmental toxin". This project is to (a) find a Natural preservative for the requirements of microbial inhibition and emulsion stability for the goats' milk body lotion, (b) demonstrate its effectiveness through microbial challenge tests and shelf-life studies and (c) develop and provide guidelines for the production process in order to minimize microbial contamination. Natural preservatives are more organism-specific than synthetic ones. Blending them has the potential to create a collective protective effect against a range of organisms, and the use of blended preservatives is a rapidly growing segment of the natural cosmetics industry. We shall also study the efficacy of paraben-free and formaldehyde-free "man-made" preservatives and their combination with natural preservatives to achieve the product stability desired. The project will have three stages: [1] Selection of preservatives, [2] Emulsion stability tests, [3] Microbial challenge tests, [4] Work complementary to the utilization of new preservatives. Solving the preservative problem for the goat's milk lotion would put the Wild Orchid Farm into a strong position for market growth.

产品的稳定性和安全性是企业的核心：产品是否表现出 所期望的或所期望的特性和行为。野生兰花农场是一个小的农村企业在山羊 该公司已扩展到生产和销售由山羊奶制成的天然化妆品 产品.他们最近配制了一种新产品，羊奶身体乳液，他们非常感兴趣。 消费者，但有一个巨大的缺点：他们使用的防腐剂混合物，是甲醛释放， 这在消费者接受度非常低的天然化妆品领域中是不可接受的。天然产品具有高 牛奶的浓度，如由野生兰花农场，需要特殊的照顾和测试，因为牛奶是一种 微生物的绝佳营养来源。野生兰花农场使用的防腐剂是Liquid Germall Plus， 方便，可抑制革兰氏阳性和阴性细菌、酵母菌和霉菌的生长。 然而，其中一个组件释放甲醛，另一个组件被描述为“疑似 环境毒素”。本项目的目的是（a）寻找一种天然防腐剂，以满足微生物的要求。 抑制和乳化稳定性，（B）通过以下方式证明其有效性： 微生物挑战试验和保质期研究，以及（c）制定和提供生产指南 以尽量减少微生物污染。天然防腐剂对生物体的特异性比 合成的将它们混合在一起有可能产生一种集体保护作用， 天然化妆品行业的一个快速增长的部分是使用混合防腐剂。 我们亦会研究不含对羟基苯甲酸酯和不含甲酰胺的“人造”防腐剂的功效，以及它们对 与天然防腐剂组合以实现所需的产品稳定性。该项目将有三个 阶段：[1]防腐剂选择，[2]乳剂稳定性试验，[3]微生物挑战试验，[4]工作 补充新防腐剂的使用。解决羊奶防腐问题 乳液将使野生兰花农场在市场增长中处于有利地位。
