Using a preservative in natural cosmetics

Many natural cosmetic makers use Liquid Germall Plus, a paraben-free broad spectrum preservative that is very effective against gram positive and negative bacteria, yeasts and moulds. It is considered safe to use and compatible with most cosmetic ingredients. However, some folks will not use it because it releases formaldehyde, albeit in very small amounts, over time. Others say that the formaldehyde has such a short life that it does not build up over time, and that‘s what makes it appealing as a preservative in natural cosmetics. The slow release of formaldehyde allows for a constant low level at all times, just enough to ensure sufficient levels to inhibit microbial growth.
