Propylene glycol diundecanoate is a substance commonly used in cosmetic products for its ability to create a thin protective layer on the skin, keeping it moisturized and soft. It also helps to control the thickness of the product, making it easier to apply. You may see this ingredient listed under different names such as 2-undecanoyloxypropyl undecanoate or isopropylene undecanoate.

What is the purpose of isopropylene undecanoate in personal care products? It is used for its film-forming, skin conditioning emollient, and viscosity-controlling characteristics. isopropylene undecanoate creates a thin layer on the skin/nails/hair, hydrates skin to prevent dryness, and adjusts the thickness of a product.

What Are Film-Forming Ingredients?

isopropylene undecanoate has film-forming characteristics.

Film-forming ingredients are used in many cosmetic products, including skincare, haircare, and makeup. These ingredients can have different chemical compositions and functions, but they all share the goal of creating a film on the surface they are applied on.

In skincare products, film-forming ingredients are often used to create a barrier on the skin's surface that helps to lock in moisture. This can benefit people with dry or sensitive skin, as it can help to prevent the skin from becoming dehydrated and irritated. Some film-forming ingredients can also provide a temporary tightening or lifting effect, which can help reduce the visibility of lines and wrinkles on your skin.

In haircare products, film-forming ingredients can help smooth and protect the hair cuticle, making hair look shinier and feel smoother. Film-forming ingredients can also help to protect hair from environmental stressors like heat styling and pollution.

In makeup products, film-forming ingredients can help create a smooth, even base for additional products like foundation or powder. They can also help to improve the wear time of makeup products by creating a barrier that helps to keep them in place.

isopropylene undecanoate has skin conditioning emollient characteristics.

Skin conditioning emollients help improve the skin's texture and appearance while providing it with the necessary hydration to prevent dryness and flakiness. Emollients are lubricants that create a barrier on the skin's surface to trap moisture, which helps prevent dryness and dehydration.

Skin conditioning emollients are commonly found in cosmetics such as moisturizers and lotions, which significantly help maintain healthy and youthful-looking skin. Emollients are typically made from natural oils, such as coconut or jojoba, and can also contain humectants that draw moisture to the skin's surface.

What Are Viscosity-Controlling Ingredients?

isopropylene undecanoate has viscosity-controlling characteristics.

Viscosity-controlling ingredients increase or decrease the thickness of a product. These ingredients are essential in creating the desired texture and consistency for cosmetic products such as lotions, creams, and serums.

Increasing the viscosity of a cosmetic product can provide a thicker and more substantial texture, making it easier to apply and providing better coverage. On the other hand, decreasing the viscosity can create a lighter, more fluid consistency, allowing for quicker absorption into the skin.
