Urban Decay All Nighter Liquid Foundation Versus Carslan Lasting Moisture Foundation

Ci 77499 is also hydrated iron III oxide. It is created from mixing red and black iron oxides. This helps give shades of darkness to a product.

Iron III oxides are classified as inorganic chemicals for coloring.

Ci 77891 is a white pigment from Titanium dioxide. It is naturally found in minerals such as rutile and ilmenite.

It's main function is to add a white color to cosmetics. It can also be mixed with other colors to create different shades.

Cyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.

D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.

Dimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane.

What it does:

Disteardimonium Hectorite comes from the clay mineral named hectorite. It is used to add thickness to a product.

It can also help stabilize a product by helping to disperse other ingredients.

This ingredient is an synthetic emollient, emulsifier, and used as a surface treatment for pigment particles (like iron oxides or titanium dioxide).

The “triisostearate” part of this ingredient is an ester derived from isostearic acid, a long-chain fatty acid.

Magnesium Sulfate is a salt. More specifically, it is an epsom salt, or the bath salt used to help relieve muscle aches.

Despite having ‘sulfate’ in the name, it isn’t a surfactant or cleansing agent like sodium lauryl sulfate. Unlike those sulfates, magnesium sulfate doesn’t have the same cleansing or foaming properties (it's simply a type of salt).

PEG/PPG-18/18 Dimethicone is a modified version of dimethicone with emulsifying properties. It helps add a silky and lightweight feel to products like sunscreens and foundations.

Its unique structure allows it to bridge the gap between water-loving and oil-loving ingredients. This makes it especially good at creating stable, velvety, and elegant formulations.

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.

Phenyl Trimethicone is a silicon-based polymer. It is derived from silica.

Phenyl Trimethicone is used as an emollient and prevents products from foaming.

This ingredient is a solvent. It helps dissolve active ingredients and alter the texture of products.

Propylene Carbonate is commonly used in makeup and with clay, such as montmorillonite or bentonite.

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.
