Théa Blephasol DuoIngredients explained
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.
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 smallish polymer molecule (created from repeated units of Polyethylene glycol, aka PEG) that's used as a solubilizer and viscosity control agent.
It is a clear, colorless liquid that is water-soluble and water-binding (aka humectant) and can help to solubilize sparingly-water soluble things (e.g. vanilla, perfumes) into water-based formulas. Thanks to its water-binding ability, it also prevents the drying out of formulas, especially when combined with the fellow hygroscopic agent, sorbitol.
It's a common little helper ingredient that helps water and oil to mix together. Also, it can help to increase the solubility of some other ingredients in the formula.
We don't have description for this ingredient yet.
A synthetic polymer (a big molecule made of repeated units) that's used as a mild cleansing agent. It is also used in contact lens solutions and a regular on the ingredient lists of micellar cleansing waters.
Chemically speaking, it is an interesting molecule with an oil-loving part in the middle surrounded by two water-loving parts. The numbers in the molecule refer to the overall molecular size and the water-loving part in it (40%). Poloxamer 184 is almost half-half oil and water-soluble, likes to form micelles (molecules gathered into a ball form with oil-loving parts inside and water-loving parts outside) and is claimed to be an effective cleansing agent that is also mild on the skin and the eyes.

A water-loving liquid that's clearly soluble in aqueous surfactant solutions, can solubilize oils and oil-soluble ingredients and has a nice skin feel. It's a popular ingredient in micellar cleansing waters.
The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right.
For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed.
BTW, lye is not something new. It was already used by ancient Egyptians to help oil and fat magically turn into something else. Can you guess what? Yes, it’s soap. It still often shows up in the ingredient list of soaps and other cleansers.
Sodium hydroxide in itself is a potent skin irritant, but once it's reacted (as it is usually in skin care products, like exfoliants) it is totally harmless.
It’s a little helper ingredient that helps to set the pH of a cosmetic formulation to be just right.
