Synthetic Wax is a manufactured hydrocarbon wax. In formulas, it works as an occlusive emollient that helps reduce water loss and improves the spreadability of products.

Research comparing synthetic wax to traditional mineral-derived products found that formulas containing it perform as well for skin hydration.

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

What it does:

This silicone is an emollient. Emollients create a thin film on the skin to prevent moisture from escaping.

It is not soluble in water and helps increase water-resistance in products.

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.

Methicone is a type of silicone and is a simpler form of dimethicone.

Silicones are used to enhance the texture of products and have emollient properties. Methicone is used to give products a silky texture and improves spreadability.

Triethyl Citrate comes from citric acid. It has masking, perfuming, and solvent properties. As a solvent, this ingredient helps disperse ingredients evenly in skincare.

One manufacturer claims this ingredient can:

Hydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.

In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.

Lecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of phospholipids.

Thanks to its amphiphilic structure (water-loving head and oil-loving tail), it is a true multitasker:

BHT is a synthetic antioxidant and preservative.

As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.

Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!).

It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome.

Mica is a naturally occurring mineral used to add shimmer and color in cosmetics. It can also help improve the texture of a product or give it an opaque, white/silver color.

Serecite is the name for very fine but ragged grains of mica.

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.

Ci 77491 is also hydrated iron III oxide. It's sole purpose is to give a red/pink hue to products.

Iron III oxides are classified as inorganic chemicals for coloring.

CI 77492 is also hydrated iron III oxide. It's sole purpose is to give a yellow hue to products.

Iron III oxides are classified as inorganic chemicals for coloring.

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.

We don't have a description for CI 77000 yet.

This synthetic powder is used to add a pearly/white color in cosmetics.

Ci 42090 is a synthetic dye created from petroleum. It is used to give a bright blue color to cosmetics, medicine, and food.

We don't have a description for CI 77400 yet.

Ci 75470 is a bright-red pigment. It is AKA carmine.

Carmine is derived from insects such as the cochineal beetle. This ingredient has been used as a natural dye for over 2000 years.

We don't have a description for CI 77289 yet.

Ci 77288 is used to add green pigment to products.

This ingredient is used to impart a blue color. It is not water-soluble.

It goes by two different names:
1. Ferric Ferrocyanide: a synthetic dark blue pigment
2. Ferric Ammonium Ferrocyanide: a synthetic blue pigment, also called Prussian blue

This ingredient is used to add a violet color to cosmetics.

It is created by reacting phosphoric acid, ammonium dihydrogen orthophosphate, and manganese dioxide.

CI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.

Tartrazine is created from petroleum and is water-soluble.
