Why preservatives are necessary

MYTH: All preservatives are dangerous and must be avoided

A water based product that is left unprotected, can quickly grow various undesirable microorganisms such microbes, bacteria, fungus, and yeast. It’s really, too much risk to take here!Preservatives do serve a purpose which is to protect consumers from bacteria, fungus, and yeast. It has been amply shown that inadequately preserved cosmetics can be hazardous to human health and cause problems such as skin infections, irritation and even blindness (case of unpreserved mascaras).The risk of using safe natural preservatives is lower than selling an unpreserved water based skincare products. 

Your safety and health come first! No compromise!

At Okoko Cosmétiques, we use natural preservatives that are effective, have wide-spectrum activity and that present low toxicity/irritation/sensitization.We provided a list of some of the most popular natural preservatives available to/used by natural skincare companies. Fortunately, technology is allowing us to become even more innovative and ingredient manufacturers are creating new, effective broad spectrum preservatives that are made from natural sources. 

When should/do we use a preservative?

Water containing products need a preservative. Even products with aloe vera, hydrosols, or hydro-soluble extracts need to be preserved. That would include things like: lotion, cream, cleanser, clay-cream, shampoo, water-based masque, etc. 

What are preservatives free cosmetics?

Waterless products: oil based

 That would include things like balm, oil based serum, massage oil, lip balm, etc. They don’t need preservatives because harmful microbes will not grow in them. If water is going to be introduced inside the product, then a preservative is needed. 

Dry clay face cleanser

Clay-based facial masques are notoriously difficult to preserve because the clay often absorbs most if not all of the preservative in your formulation. (Formula Botanica). In this case, the most acceptable option is to use a blend of synthetic preservatives that include phenoxyethanol. So we at Okoko, preferred to sell our clay masks in a powdered form instead.
