Benzoyl Isopropanol: An In-Depth Look at Its Role in Cosmetics

What Is Benzoyl Isopropanol?

Benzoyl Isopropanol, also known by its chemical name 1-Propanone, 2-Hydroxy-2-Methyl-1-Phenyl-, is a synthetic compound primarily used in the cosmetic industry for its film-forming properties. This ingredient is often included in various skincare and makeup products to create a smooth, even layer on the skin, enhancing the product’s texture and longevity.

The history of Benzoyl Isopropanol in cosmetics dates back to the mid-20th century when chemists began exploring new synthetic compounds to improve the performance and feel of cosmetic formulations. Its ability to form a flexible, breathable film on the skin made it a popular choice among formulators looking to enhance the durability and finish of their products.

Benzoyl Isopropanol is typically synthesized through a series of chemical reactions involving benzoyl chloride and isopropanol. The process begins with the reaction of benzoyl chloride with a base to form benzoyl alcohol, which is then further reacted with isopropanol under controlled conditions to yield the final product. This method ensures a high-purity compound suitable for use in cosmetic applications.

The Benefits/Uses of Benzoyl Isopropanol

In this section, we will delve into the officially recognized cosmetic benefits and uses of Benzoyl Isopropanol:

Film Forming

Benzoyl Isopropanol is primarily known for its film-forming properties. This means that when applied to the skin or hair, it creates a thin, continuous layer or “film” on the surface. This film can serve multiple purposes in cosmetic products:

• Enhanced Product Longevity: The film can help to lock in other active ingredients, ensuring they stay on the skin or hair for a longer period. This can make products like moisturizers, sunscreens, and hair treatments more effective over time.
• Improved Texture and Feel: The film can provide a smooth, even texture to the skin or hair, making it feel softer and more conditioned. This is particularly beneficial in products like lotions, creams, and hair conditioners.
• Protection Barrier: The film can act as a protective barrier against environmental aggressors such as pollution, UV rays, and harsh weather conditions. This can help in maintaining the health and appearance of the skin and hair.

Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Benzoyl Isopropanol is generally considered safe for use in cosmetic products, with a low risk of causing significant adverse reactions. However, as with any ingredient, there are potential side effects that users should be aware of:

• Skin irritation
• Redness
• Dryness
• Allergic reactions

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Benzoyl Isopropanol during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.

Adverse reactions to Benzoyl Isopropanol are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure personal tolerance.

In terms of comedogenicity, Benzoyl Isopropanol is rated as a 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating indicates that it is unlikely to clog pores and cause acne or breakouts, making it suitable for individuals prone to blemishes.
