Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
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'.

Copernicia Cerifera Wax contains aliphatic esters, diesters of cinnamic acid, myricyl cerotate, and small quantities of cerotic acid and myricyl alcohol.
Copernicia Cerifera Wax has the highest melting point of all natural waxes and low solubility.
Copernicia Cerifera Wax has commonly been used in Brazilian Folk medicine.

Hydrogenated Polydecene is an emollient. It creates a non-occlusive film on the skin that offers extra protection for your skin barrier.
The texture of Hydrogenated Polydecene ranges from light and silky to rich.
Hydrogenated Polydecene is the end compound of controlled hydrogenation of Polydecene.
Learn more about Hydrogenated PolydeceneHydrogenated 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.

Mica is found to be safe. 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.
Mica can be naturally found throughout the world. However, some sources of mica may be controversial. In 2016, mica mined in the Jharkhand state in India was found to be using child labor. However, companies are able to source ethical mica affiliated with international organizations that monitor the mica supply chain.

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.

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%.
Learn more about PolybuteneSilica Silylate is a siloxane polymer, meaning it is made up of silicon and oxygen atoms. It is not soluble in water.
This ingredient is a white powder with oil-absorbing, emollient, and anticaking properties.
Synthetic 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.
