Similar to other silicones, it gives skin and hair a silky, smooth feel. It's often combined with the non-volatile (i.e. stays on the skin) dimethicone as the two together form a water-resistant, breathable protective barrier on the skin without a negative tacky feel. Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. Expand to read more Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying. One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time. A clear, colorless, low viscosity, volatile (does not absorb into the skin but rather evaporates from it) silicone fluid that has excellent spreadability and leaves a light, silky and smooth feel on the skin. According to manufacturer info, its big advantage is that it's compatible both with other silicones and with natural plant oils, so it's a great ingredient to formulate products with good-sounding, consumer-pleasing vegetable oils but still maintain a cosmetically elegant, non-greasy and non-tacky feel. Coconut Alkanes is a volatile (something that does not absorb into the skin but evaporates from it), naturally derived vegetable alkane coming from renewable sources. It is a light, oily liquid that works as an emollient and gives a smooth skin feel. It's often combined with another emollient called Coco-Caprylate/Caprate and the two together can serve as a great replacement for some volatile silicones, like Cyclopentasiloxane. Porous spherical microbeads (tiny little balls) that can give an elegant silky texture to the products. They are also used to scatter light to reduce the look of fine lines on the skin, as well as to absorb excess oil and give a matt finish. A solid silicone resin that creates a permeable film over the skin. It makes makeup formulas more long-lasting and can enhance the water resistance of sunscreens. It leaves a non-tacky film when dried. A silicone emulsifier that helps water to mix nicely with silicone oils (aka water-in-silicone emulsifier). A light emollient ester (C8-10 fatty acids connected to C12-18 fatty alcohols) that absorbs quickly and leaves a dry but silky finish on the skin. In terms of skin feel, it is similar to Dicaprylyl Carbonate, another commonly used light emollient. A PEG-modified self-emulsifying crosslinked silicone elastomer surfactant that helps water to mix nicely with silicone oils, aka a water in silicone emulsifier.
