A crucial component to any skin care formulation is the need to establish an effective preservative system. The climate that is Australia requires a certain level of preservation to skincare products to help inhibit microbial growth. Last thing you want is your products getting moldy and rancid after only a few weeks of purchase. Inadequate preservation can compromise the structure, effectiveness and freshness of the product. Any formulation that includes water in it or any product that may get water in it NEEDS a preservative to avoid bacteria forming and to keep germs at bay. That includes most lotions and creams & scrubs.

Preservatives we use.
Optiphen Plus is a globally approved liquid preservative developed for paraben and formaldehyde-free preservation. This blend of phenoxyethanol, sorbic acid, Caprylyl Glycol and an emollient base is ideal for personal care products. The combination of all four ingredients offers effective protection against bacteria, yeast and mould growth. Used at less 1% (.75%) of the formulation.
We are currently researching “natural” preservation options available and their suitability in our products and effectiveness withstanding the Australian climate. In due course we will be looking to phase out the above preservative in favour of a 100% natural preservative. Preservative Efficacy Testing is a time consuming, lengthy process that requires much trial and error but it is so very important to conduct this testing to ensure product safety. Once we discover a truly 100% natural, vegan, palm oil free preservative system that can offer excellent product stability and resistance to microbial contamination we’ll make the change.
