化妝品具有美白、抗老化、撫平細紋等功能，這些功能的有效成份本身多是油脂或營養 成份，極易受到微生物感染而發生變質腐敗，導致產品品質下降。防腐劑是指可以阻止產品 受到微生物污染，延長產品貨架壽命，確保產品的安全性。 國內外學者紛紛以不同的植物中提取抑菌物質，並試圖將其開發成為防腐劑。有關化妝 品成份中的防腐劑導致乳癌、濕疹、過敏的實例，消費者對成份的重視程度提高，目前市場 上的化妝品成份使用的防腐機制與防腐劑類別評估比較以及探討健康趨勢的綠色防腐劑原料 及配方。 溫泉微生物原料應用清潔配方研究發現能減少頭皮微生物量，可持續36小時。在面膜 配方中發現含有溫泉微生物原料可延長產品的保存，單一無添加防腐劑往往需要兩種以上 混合使用，以達抑菌目的。綠色保養品的應用為現在關注的話題及未來化妝品產業主流趨 勢，並可提供化妝品科技與科學應用以及健康促進相關研究參考。

It is well known cosmetic whitening, anti-aging, smooth fine lines and other functions, the active ingredient of these functions themselves are mostly fats or nutrients, vulnerable to microbial infection occurs deterioration of corruption, resulting in decreased product quality. Preservative is one that can prevent products subject to microbial contamination and extend the shelf life of the product to ensure product safety. Scholars have antibacterial substance extracted in different plants, and trying to develop to become a preservative. The cosmetic composition of the preservative leads to breast cancer, eczema, allergic instance，consumer emphasis on improving ingredients, cosmetic ingredients zero added currently on the market for use in assessment categories corrosion mechanism preservatives and investigation on healthy trends and agent of raw materials and formulations. Hot Springs microbial cleaning formulations applied research materials found to reduce scalp microbial biomass, sustainable 36 hours. Save containing hot spring microbial materials to extend the product found in the mask recipe,No preservatives often require a single or two or more mixed, to achieve antibacterial purposes. Application of green skin care products for today and the future topic of concern to the mainstream cosmetics industry trends, and provide cosmetic science and technology and scientific research applications as well as health promotion reference.
