Function of Potassium Sorbate in Skincare

Earlier on the blog, we explored the use of benzyl alcohol in skincare, which serves a similar purpose to Potassium sorbate. These ingredients are used as preservatives in skincare products, to extend shelf lives and ensure a product remains sanitary and stable for use over a long period. Potassium sorbate presents some unique properties that we will dive into today.

What is Potassium Sorbate and what does it do?

Potassium Sorbate is a mild preservative, it has antibacterial and antifungal properties that ensure your skincare and cosmetic products are shelf-stable and remain hygienic for use in your daily routine. It is used much like benzyl alcohol as an alternative preservative to parabens -- which have become controversial due to potential health effects. The compound is the potassium salt found in sorbic acid, a naturally occurring mineral that is synthetically replicated and used in various skincare and cosmetic products.

Is Potassium Sorbate Safe to use on the skin?

Potassium Sorbate is safe to use in skincare, though it is avoided by people who favor products without any preservatives. Some people have an allergy to potassium sorbate, but this is incredibly rare. The preservative works effectively to combat bacteria, fungi, and mold from colonizing your favorite beauty and skincare products, and it ensures that a product’s performance remains consistent across its entire shelf life.

Potassium Sorbate in Skincare FAQ:

Potassium Sorbate or Benzyl Alcohol -- which is better?

There are very few major differences between the function of these two preservatives. Both are safe to use and work effectively. The unique properties of Potassium Sorbate that may be of interest are its slightly milder nature due to being a distilled salt, whereas some people may note more dryness or allergic reactions with benzyl alcohol. These effects are still relatively rare, and either ingredient is safe to use on the skin in conjunction with most other skincare ingredients.

Does Potassium Sorbate irritate the skin?

Potassium sorbate is unlikely to irritate the skin, as it is a very mild preservative suitable for sensitive skin.
