Preservatives and antioxidants

Preservatives and antioxidants are used to protect cosmetic products during storage and use. However, individual ingredients in this category can have different functions – some act as antimicrobials , others act as broad-spectrum preservatives , boosters or antioxidants .

Antimicrobial preservatives are substances that limit the growth of microorganisms in cosmetic products containing water. Their effectiveness can be targeted to specific groups of microorganisms and is influenced by pH, dosage and overall composition of the formulation.

Broad-spectrum preservatives act against a wider range of microorganisms simultaneously and are often used as the main preservative system in aqueous formulations. They are particularly suitable for creams, emulsions, gels, shampoos, lotions and other products where comprehensive product protection is required.

Preservative boosters do not replace a full-fledged preservative by themselves, but they increase the effectiveness of the preservative system or contribute to the stability of the formulation. They are often combined with antimicrobial or broad-spectrum preservatives to optimize their dosage or extend the effectiveness of the system.

Antioxidants do not protect the product from microorganisms, but from the oxidation of oil components. They are used primarily in oils, butters, balms and emulsions, where they help slow down changes in properties caused by the action of oxygen.

In this category you will find preservative systems, auxiliary ingredients and antioxidants suitable for various types of cosmetic products. When choosing them, it is important to take into account the water content, pH of the formula, type of product and combination of individual ingredients.
