Preservative 1388 Eco Plus, 100 ml

Preservatives are substances that help extend the shelf life of your cosmetic products.

They combat bacteria, yeasts, fungi and moulds in cosmetics by being able to stop their proliferation for a certain period of time. They are needed wherever you add water to products. However, these properties predestine them to be potentially poisonous or toxic in their pure form, therefore their dosage in cosmetic products is minimal.

Preservative 1388 eco plus is a modern broad-spectrum antimicrobial ingredient intended for the preservation of cosmetic products. It contains sodium salt of levulinic acid, sodium salt of anisic acid, glycerin and water, which makes it a 100% natural and vegan blend. Thanks to the optimal ratio of active substances, it provides reliable protection against bacteria, yeasts and moulds, while not causing any change in the colour or scent of the final product.
