Synercide Herbal Fusion


Advances in technology have allowed for the evolution of preservation techniques throughout the centuries. Some of the original approaches included dehydration and fermentation. Other traditional methods used for preservation have involved creating herbal tisanes. Of course today there is a need to preserve more than just food. Although some of the aforementioned techniques are still utilized, until recently, more popular methods for the preservation of cosmetics have been the use of ingredients such as parabens and phenoxyethanol. However as these ingredients have fallen out of favor with consumers, chemists have been striving to find effective alternatives.


Active Micro Technologies has taken a unique approach by developing the Synercide Fusion line of products, which are a fusion of traditional and more modern preservation techniques. These actives are intended to provide skin conditioning and hydrating benefits as well as inhibit microbial growth.

Synercide Herbal Fusion consists of oregano, thyme and rosemary extracted in caprylyl and hexylene glycols. In this system, the glycols act as more than just a solvent as they are understood to provide emollient and humectant properties.

Oregano is a widely recognized herb that is frequently used as an accent in a variety of Mediterranean cuisines. Traditionally used as an antiseptic, the botanical contains phytocompounds such as oleanolic and caffeic acids. These are capable of providing protection against oxidative stress which contributes to aging. In addition to its culinary uses, thyme has been used medicinally to treat both infection and inflammation. Thymol, an essential oil in thyme was historically used on bandages before the advent of antibiotics. Long credited with improving one’s memory, research has shown that Rosemary may actually enhance cognitive function while providing antioxidant protection.
