Which statement is NOT true of silicones?

1. They provide a smooth application

2. They are often non-comedogenic

3. Their names almost always end in "ate"

4. They can create a barrier on the skin

The correct answer is: Their names almost always end in "ate"

Silicones are a group of synthetic compounds commonly used in skincare and cosmetic products. They are known for their beneficial properties, including providing a smooth application, which is essential for the feel and spreadability of products. Additionally, many silicones are non-comedogenic, meaning they do not clog pores, making them suitable for various skin types, including acne-prone skin. Furthermore, silicones can form a barrier on the skin, which helps to lock in moisture and improve the texture of the skin. The statement that their names almost always end in "ate" is not accurate. While some chemicals that are based on silicone, such as dimethicone or cyclopentasiloxane, may contain names ending in "cone" or "siloxane,” they do not primarily end in "ate." This characteristic does not apply to silicones as a class of compounds, which is why this statement is considered NOT true. Understanding the naming conventions and properties of silicones is essential for estheticians when selecting products for skincare routines.
