Is Isopropyl Isostearate Comedogenic?

Isopropyl Isostearate is highly comedogenic. It means that if this ingredient is present in any product, it is very likely to cause pimples on acne prone skin. Even if your skin does not break out easily, you need be careful with products containing this ingredient.

Comedogenic ingredients are pore-clogging and can cause breakouts.

Even if a single ingredient such as Isopropyl Isostearate in a skincare or cosmetic / makeup product is comedogenic, that becomes its weakest link, rendering the product as a whole comedogenic. Manually checking an ingredient list for the presence of comedogenic ingredients can be tiresome.

Depending on your Acne Prone Skin Type (1, 2 or 3), an ingredient may block your pores more or less depending on its comedogenicity. You need to be aware of these acne causing ingredients that may cause or aggravate acne.

Many comedogenic cosmetic ingredient lists rate comedogenic ingredients on a scale of 1-5, with 5 being the most comedogenic. In real life, comedogenicity does not vary at such a fine scale. You are better off using a more practical scale such as non-comedogenic, mildly comedogenic and highly comedogenic.

Isopropyl Isostearate is not known to be irritating to the skin. Skin irritants may cause acne even if they are not pore-clogging. This is because they irritate the skin causing it to produce more sebum which may result in acne.

Isopropyl Isostearate is mainly used as an emollient, binding agent and skin conditioner in cosmetic products.
