Does the preservative-free system really have no preservatives?

What’s ”No preservative system”?

Everyone’s understanding of No preservative system is that no preservatives are added. As long as the 51 preservatives in the “Safety Technical Specifications for Cosmetics” (2015 edition) are not added, many businesses can advertise that the products do not add preservatives, that is No preservative system. However, it is still necessary to add antiseptic ingredients, just it is not in the prescribed preservatives category. In fact, this approach is to change the concept secretly. Just from a commercial point of view, it is more attractive to consumers.

What’s non-preservative antiseptic substances?


pentanediol, hexanediol, octanediol, phenethyl alcohol, etc.

they are raw materials with antiseptic function or auxiliary antiseptic function, but at the time of registration, it was cleverly not registered as a “preservative” but as a “humectant”. Preservatives formulated with such a system can be declared as “preservative-free” because there is indeed “no preservative”, or in other words, no preservatives “registered”.

Long carbon chain polar hydrophilic lipophilic substance:

ethylhexylglycerol, glyceryl caprate, capric acid, glyceryl caprylate, sorbitan caprylate, glyceryl undecylenate, etc.

organic acid:

levulinum Acid, anisic acid, octanoyl hydroxamic acid, etc.; ketones: p-hydroxyacetophenone, etc.

natural extracts:

such as peony root extract. Of course, what can be preserved in this is still chemicals, but chemicals of natural origin (such as paeonol, paeoniflorin, paeoniflorin, β-sitosterol, gallic acid, tannins). In the pharmacological experiment report, peony Root extract is certified to have sedative, bactericidal, anti-inflammatory, anti-oxidant, and anti-allergic effects. For example, these two ingredients can be basically seen on the ingredient list of various products: 1,2-pentanediol and ethylhexylglycerol.

Preservatives are added to prevent the growth of microorganisms. One concept that needs to be corrected is that, products that do not add preservatives, and products that can last for a long time, only use another preservative ingredient to inhibit the growth of microorganisms, and It is not that preservatives are not added. From a commercial point of view, it is better to promote and meet the needs of consumers.
