Natural Preservatives to Extend Stability and Shelf-Life of Goats' Milk Natural Cosmetic Products

产品的稳定性和安全性是企业的核心：该产品是否展示了 想要的或宣传的特征和行为。野生兰花农场是一家经营山羊的农村小企业 养殖业已经扩展到生产和销售由山羊乳制品制成的天然化妆品 产品。他们最近研制出了一种新产品--山羊奶身体乳液，这引起了他们的极大兴趣 消费者，但有一个巨大的缺点：他们使用的防腐剂混合物，释放甲醛， 在消费者接受度极低的天然化妆品领域不可接受。天然产物具有很高的 浓缩牛奶，如野生兰花农场生产的牛奶，需要特殊的护理和检测，因为牛奶是一种 为微生物提供极好的营养来源。野生兰花农场使用的防腐剂是液体Germall Plus，一种 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，其中一种ts成分释放出甲醛，另一种被描述为“怀疑是一种 这个项目是为了(A)寻找一种符合微生物要求的天然防腐剂 山羊乳体乳液的抑制性和乳状液稳定性，(B)通过以下方法证明其有效性 微生物挑战测试和保质期研究；(C)制定和提供生产指南 工艺，以最大限度地减少微生物污染。天然防腐剂比传统防腐剂具有更强的生物特异性 人工合成的。将它们混合在一起可能会产生集体保护效果，以抵御一系列 使用混合防腐剂在天然化妆品行业中是一个快速增长的细分市场。 我们亦会研究不含对羟基苯甲酸酯和甲醛的“人造”防腐剂及其防腐剂的功效。 与天然防腐剂相结合，达到所需的产品稳定性。该项目将有三个 阶段：[1]防腐剂的选择，[2]乳状液稳定性试验，[3]微生物挑战试验，[4]工作 补充使用新的防腐剂。解决羊奶的防腐问题 乳液将使野生兰花农场在市场增长方面处于有利地位。

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.
