Kosé Carté HD Balance Care Lotion

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Dipropylene Glycol is a synthetically created humectant, stabilizer, and solvent.

This ingredient helps:

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

Serine is a non-essential amino acid (your body makes it on its own!). It is a major player in your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.

Serine is one of your NMF's most abundant components that works as a skin-identical humectant. Its hydroxyl group grabs onto water molecules to boost hydration without any heaviness or occlusion.

Theanine is an amino acid found in plants and fungal species. It helps hydrate the skin as an emollient and humectant.

Both emollients and humectants help hydrate the skin. Emollients prevent moisture from escaping by creating a thin film on top of the skin. Humectants draw water from the air to your skin.

Capryloyl Glycine is created by adding an acyl group to glycine and caprylic acid chloride.

It is a cleanser due to its surfactant properties. Surfactants help dirt, oil, and other polluants be more easily rinsed away. According to manufacturers, Capryloyl Glycine also helps soften the skin and regulate sebum production.

Pyridoxine hydrochloride, also known as vitamin B6, has skin conditioning properties. According to a manufacturer, this ingredient is an effective anti-dandruff treatment as it reduces sebum levels and oily spots.

Isostearic acid is a saturated fatty acid. Its structure makes it a great surfactant.

Surfactants help decrease the surface tension between two liquids. This property also makes it an effective emulsifier. Emulsifiers help prevent waters and oils from separating in a product.

Disodium EDTA is a chelating agent. It grabs onto and deactivates metal ions that sneak into your products from water, packaging, or air.

This ingredient mainly works behind the scenes and helps with:

Carbomer is a high-molecular weight polymer of acrylic acid. It is used to form gels and thicken formulas.

Due to its large molecular size, carbomer has minimal skin penetration and is considered an inert ingredient.

Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.

We don't have a description for Glycerylamidoethyl Methacrylate/Stearyl Methacrylate Copolymer yet.

Glyceryl Glucoside is made from glycerol and glucose.

It is a humectant. Humectants help hydrate your skin by drawing moisture to it from the air.

This is a fermented gum derived from sorbitol, a sugar alcohol.

According to a manufacturer, this ingredient's high molecular weight makes it an effective emollient.

Phytosterols are plant-derived sterols (you can think of them as the plant world's version of cholesterol). In cosmetics, this ingredient is usually sourced from soybean, rice bran, shea, sunflower, and other seed oils.

The main actors in this group are β-sitosterol, campesterol, and stigmasterol (the CIR covers 27 phytosterols).

PEG-40 Hydrogenated Castor Oil is an emulsifier derived from castor oil.

As an emulsifying agent, it helps other ingredients like fragrances and fat-soluble vitamins dissolve cohesively.

Disodium Phosphate is a water-soluble powder used as a pH adjuster and mild chelating agent. It basically holds a specific pH and binds stray metal ions so your product stays stable.

This ingredient is usually used at very low levels and concentrations range from 0.000054% - 2.9%. The CIR Expert Panel states this ingredient to be non-irritating at current use levels.

Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

Methylparaben is a preservative and is a paraben. It is used to prevent the growth of fungus, mold, and other harmful bacteria. Parabens are chemicals used as preservatives in both cosmetics and food.

Methylparaben can be synthetically created. It can also be found naturally in some fruits, such as blueberries.
