These additives make sure that the alcohol is poisonous and bad tasting so that nobody drinks their alcohol-loaded toner. 40-B specifically means the additives are denatonium benzoate and t-butyl alcohol. As for Alcohol Denat in skincare, it's a controversial ingredient. It's a great solvent and makes cosmetically elegant, light formulas but at best it's skin-drying, at worst it's skin-barrier damaging. We have written about alcohol way more here. 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. Witch hazel is a smallish tree (up to 5m) that's native to North-America, has nice yellow flowers and is similar to the hazelnut bush (hence the name). As for skincare, it's loaded with active components that have a bunch of magic properties, like astringent, anti-inflammatory, antioxidant and anti-bacterial. It's also a well-known vasoconstrictor (it makes the blood vessels narrower) and promotes the healing of broken skin by tightening up the skin proteins and thus creating a protective covering. The complication, however, is that different extracts and distillates can be made from different parts of the plant (bark, twigs, and leaves are typically used) and different extraction methods from different parts produce different results. So if you see only Witch Hazel Extract or Witch Hazel Water on the ingredient list, it's a bit hard to know what you're actually getting but we will try to summarize the possibilities to give an idea. The main biologically active components in Witch Hazel are hamamelitannin (a potent astringent and antioxidant), catechins (anti-inflammatory and antioxidant) and gallic acid (antibacterial). The bark extract contains by far the most hamamelitannin and it has the most gallic acid and catechins. The twigs contain fewer catechins, less gallic acid, and much less hamamelitannin (4.77% vs 0.18%). The leaves contain hardly any tannins (0.04%) or catechins and contain a medium amount of gallic acid (compared to the bark and twigs). Witch Hazel also contains tiny amounts of the essential oil and fragrance component eugenol, but the amount is so small that it's probably not significant for the skin. Apart from the differences in active components in different parts of the Witch Hazel bush, the extraction methods also vary what‑it‑does solvent | viscosity controlling soothing | antioxidant | antimicrobial/antibacterial moisturizer/humectant | solvent irritancy, com. exfoliant | moisturizer/humectant | buffering anti-acne | soothing | buffering antioxidant | skin brightening antioxidant | preservative
