Magnesium Stearate is a salt that is 2 parts stearic acid and 1 part magnesium.

It is a white powder that can be used to add bulk and color to products by binding to oil ingredients.

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

What it does:

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.

Octyldodecyl Stearoyl Stearate is an emollient ester that mostly shows up in color cosmetics.

Functionally, it works as a skin-conditioning agent and a viscosity-increasing agent. This just means it helps soften skin while also thickening water-free formulas (like powders).

Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.

Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.

Hydroxyacetophenone is antioxidant with skin conditioning and soothing properties. It also boosts the efficiency of preservatives.

Though naturally occuring in Norwegian spruce needles, this ingredient is usually synthetically created.

Bis-Diglyceryl Polyacyladipate-2 is a synthetic emollient that works as a lanolin substitute.

This ingredient is a great vegan option for those avoiding animal-derived ingredients.

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.

One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.

Kaolin is a clay. It is used for oil control and to help minimize pores. Like other clays, kaolin has the ability to absorb excess sebum or oil. This can help clean out pores and mattify the skin.

Some types of kaolin may have exfoliating properties. When water is added to kaolin, it becomes a paste with small abrasive particles.

Boron Nitride is compound consisting of boron and nitrogen. It is used to absorb oil and modify adherence/ slip in products.

This means it is often used in makeup products to help them last longer.

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.

Ethylhexyl Palmitate, also known as octyl palmitate, is created from 2-ethylhexyl alcohol and palmitic acid.

In cosmetics, it plays many roles:

Isononyl Isononanoate is a synthetic skin-conditioner and texture enhancer. It is created from nonanoic acid, a fatty acid found in cocoa and lavender oil.

As an emollient, Isononyl Isononanoate helps keep your skin soft and smooth. This is because emollients create a barrier on the skin to trap moisture in.

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

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

Tridecyl Trimellitate is a synthetic ingredient with emollient and skin conditioning properties. It also acts as a texture enhancer and helps products spread easily without feeling greasy.

As an emollient, it forms a light layer on the skin that keeps moisture in and improves water resistance. This is why you'll often find this ingredient in eye creams and other rich treatments.

Isopropyl Isostearate is a synthetic ester made by combining isopropyl alcohol and isostearic acid. Its an emollient that helps hydrate skin.

This also allows it to improve spreadability of a product and give products a silky feel on skin.

Tocopherol is a fat-soluble antioxidant known as Vitamin E.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.

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.

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

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.

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.

Triethoxycaprylylsilane is a silicon-based surface modifier that makes sunscreens feel silky and makeup stay put.

Its main job is to coat mineral particles like titanium dioxide, zinc oxide, and color pigments in a thin, oily layer so they spread smoothly, don't clump, and stick to skin better.

Tin Oxide is an inorganic oxide used to add opacity and volume to a product. In nature, it is already found in mineral form. The main ore of tin is an opaque and shiny mineral called casseterite.

Tin Oxide helps remove translucency in a product, or make it more opaque. Besides adding opacity, tin oxide is used for bulking to add volume.

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.

Maltodextrin is a polysaccharide. It is derived from starch such as rice, corn, wheat, or potato starch.

In food, Maltodextrin is used to improve the texture and thicken a product. Due to its structure, it can help create a gel texture. As an emulsion stabilizer, it helps keep the ingredients in a product together.
