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. Butylene glycol, or let’s just call it BG, is a multi-tasking colorless, syrupy liquid. It’s a great pick for creating a nice feeling product. BG’s main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin. It’s an ingredient whose safety hasn’t been questioned so far by anyone (at least not that we know about). BG is approved by Ecocert and is also used enthusiastically in natural products. BTW, it’s also a food additive. We don't have description for this ingredient yet. A handy helper ingredient (a polymer, i.e. big molecule from repeated subunits) that is used to stabilize emulsions as well as to thicken up products. It can also stabilize foam in cleansing products. If you ever wondered what those little Listerine breath strips were made of, you found your answer! Pullulan is a polysaccharide polymer, which basically means that it’s a big molecule made up of smaller sugar molecule units. It dissolves in water and can make a thin, elastic, and moisture-absorbing film when spread on the skin that can cause an instant tightening effect. It can also be used as a thickener to get a silicone-like feel and can be used in peel-off masks. Btw, it's made from fungus via fermentation. It’s the - sodium form - cousin of the famous NMF, hyaluronic acid (HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here. The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water. As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephen writes on reddit "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution". In spite of this, if you search for "hyaluronic acid vs sodium hyaluronate" you will find on multiple places that sodium hyaluronate is smaller and can penetrate the skin better. what‑it‑does moisturizer/humectant | solvent irritancy, com. surfactant/cleansing | viscosity controlling skin-identical ingredient | moisturizer/humectant antimicrobial/antibacterial | preservative
