What is the primary purpose of dimethicone copolyol in skincare products?

Makes a product soft
Provides SPF protection
Enhances fragrance
Acts as a preservative

The correct answer is: Makes a product soft

Dimethicone copolyol is primarily used in skincare products for its ability to soften and provide a smooth, silky texture. As a silicone compound, it creates a lightweight barrier on the skin, which helps to improve the feel of the product and enhances the overall application experience. This softening property makes it a popular ingredient in formulations aimed at moisturizing and conditioning the skin. While dimethicone copolyol might have other beneficial properties, such as acting as a light emollient, its main function is to create that desirable softness and smoothness. Other options like providing SPF protection, enhancing fragrance, or acting as a preservative do not align with the primary characteristics or common uses of dimethicone copolyol, which is focused on texture and feel rather than functional attributes related to protection, scent, or longevity of the product.
