Ingredients Explained
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.
Hydrogenated Polyisobutene is often used as a mineral oil replacement.
Learn more about Hydrogenated PolyisobuteneIsododecane is a fragrance, emollient, and solvent.
As an emollient, it helps your skin stay soft and hydrated. Emollients help trap moisture into your skin.
Isododecane's role as a solvent makes it a great texture enhancer. It spreads smoothly on skin and does not leave a sticky feeling behind. Isododecane also helps prevent color transfer in makeup products.
Isododecane is not absorbed into skin.
The chemical name for this ingredient is 2,2,4,6,6-PENTAMETHYLHEPTANE.
Learn more about IsododecaneSynthetic Wax is created from fossil fuels such as natural gas. It is used to enhance texture, adjust pH, and as an occlusive.
It may also be used as an abrasive ingredient to exfoliate the skin.
Synthetic Wax may not be fungal acne safe.
Learn more about Synthetic WaxPolymethylsilsesquioxane is a silicone used as a film forming agent.
When applied to the skin, this ingredient creates an invisible film on the surface. This film still allows oxygen to pass through, but prevents moisture from escaping. This can help condition and hydrate the skin. It also leaves a silky feel when applied.
Polymethylsilsesquioxane has not been shown to clog pores. It has been deemed safe to use up to 55%, but most cosmetics use much less.
If you have concerns about using this ingredient, we recommend speaking with a professional.
Learn more about PolymethylsilsesquioxaneSilica, also known as silicon dioxide, is a naturally occurring mineral. It is used as a fine, spherical, and porous powder in cosmetics.
Though it has exfoliant properties, the function of silica varies depending on the product.
The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.
It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.
In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.
Learn more about SilicaPolybutene is used to help control the viscosity of a product. This just means it helps adjusts the texture.
It is a polymer and does not get absorbed into the skin due to its large size.
Studies found this ingredient did not irritate skin in concentrations below 15%.

Oryza Sativa Bran Wax is wax from the outer layer of a rice kernel. It has moisturizing properties due to its polysaccharides and omega-3 fatty acids content.
This ingredient is a byproduct of milling rice, or the operation to produce a whole grain rice product.
Hydrogenated Castor Oil is created by adding hydrogen to castor oil. This helps stabilize the castor oil and raises the melting point. At room temperature, hydrogenated castor oil is solid.
Castor Oil helps moisturize the skin. It is rich in a fatty acid called ricinoleic acid. This fatty acid helps prevent moisture loss on the skin. This helps keep your skin soft and hydrated. Ricinoleic acid also has anti-inflammatory and pain reducing properties.
As a wax-like substance, Hydrogenated Castor Oil acts as an emollient. Emollients help keep your skin stay soft and smooth by creating a barrier. This barrier helps trap moisture.
Hydrogenated Castor Oil may not be fungal-acne safe. We recommend speaking with a professional.
Learn more about Hydrogenated Castor OilSynthetic beeswax is created to be identical in structure to beeswax. It possesses the same occlusive and emulsion properties.
A blend of fatty acid esters, fatty acids, and alcohols are used to create synthetic beeswax. Whether or not this ingredient is vegan depends on the source. Sometimes, lanolin is used for its creation.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Learn more about Synthetic BeeswaxEthylene/Propylene Copolymer is an exfoliant.
Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (long name, huh?) is a synthetic antioxidant.
It is used to help stabilize other antioxidants or prevent the color from changing in a product.
As an antioxidant, it helps fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material. Thus, antioxidants may reduce the signs of aging.
This ingredient is oil-soluble.
Learn more about Pentaerythrityl Tetra-Di-T-Butyl HydroxyhydrocinnamateCi 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 77000 yet.
This pigment is called Ultramarine blue lazurite. It gives a saturated blue color, but can be used to create other colors as well.
According to the manufacturer, it is usually made from kaolin, sodium sulfate, sodium carbonate, sulfur, and charcoal.
This synthetic powder is used to add a pearly/white color in cosmetics.
Ci 77288 is used to add green pigment to products.
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.
Synthetically created Ci 77491 is considered safer than those naturally found. This is because the synthetically created version may contain less impurities. Iron oxides are generally non-toxic and non-allergenic.
Learn more about CI 77491CI 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.
Synthetically created CI 77492 is considered safer than those naturally found. This is because the synthetically created version may contain less impurities. Iron oxides are generally non-toxic and non-allergenic.
Learn more about CI 77492Ci 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.
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
In the EU, both of these colors must be labeled as 'CI 77510'.
Learn more about CI 77510This ingredient is used to add a violet color to cosmetics.
It is created by reacting phosphoric acid, ammonium dihydrogen orthophosphate, and manganese dioxide.
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 77891 is commonly found in sunscreens due to its ability to block UV rays.
Learn more about CI 77891Mica 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.
This ingredient is often coated with metal oxides like titanium dioxide. Trace amounts of heavy metals may be found in mica, but these metals are not harmful in our personal products.
Mica has been used since prehistoric times throughout the world. Ancient Egyptian, Indian, Greek, Roman, Aztec, and Chinese civilizations have used mica.
