Ingredients explained

Dimethicone
Est. %45
Function
Origin
The most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Isododecane
Est. %22
Function
Origin
An emollient derived from petroleum with high spreadability. It is often used as a replacement for oils and silicones because it leaves no residue behind on the skin. When a product is labeled as “oil-free” it may contain isododecane instead of heavier oils.
Talc
Est. %11
Function
Origin
A mineral powder used as a base material for powders, make-up, and pastes that absorbs sweat and oils very well. It is also often used in baby powders. Talc should never be applied to skin with a damaged lipid barrier (e.g. wounds and burns).
Dimethicone Silylate
Est. %6

Trihydroxystearin
Est. %4
Function

Disteardimonium Hectorite
Est. %3
Function
Origin
A clay ingredient that functions primarily as a viscosity controlling agent that thickens all types of formulas. Disteardimonium hectorite imparts a smooth, velvety feel, making it a luxurious addition to any formula.
Kaolin
Est. %2
Function
Origin
A type of mineral clay milled into a white, very fine powder. It is able to absorb sweat and oil, which then helps to keep the skin matte. The larger particles of kaolin are used in skin scrubs as an abrasive ingredient.
Hydrogenated Polyisobutene
Est. %1.5
Function
Origin
A viscous liquid that makes a great oil base due to its smooth sensorial profile. It has emollient features, including good spreadability and little tack upon application. It also has the added benefit of being able to thicken products.
Polyethylene
Est. %1
Function
Origin
Commonly used in dense plastic packaging, its primary function in skincare is as a film-forming agent, which protects the product from being easily rinsed away by water or sweat. It also controls viscosity by increasing the thickness of oily products.
VP/Eicosene Copolymer
Est. %0.3
Function
Origin

Trioctyldodecyl Citrate
Est. %0.3
Function
Origin
Description is coming soon
Tocopheryl Acetate
Est. %0.3
Function
Origin
An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.
Lecithin
Est. %0.3
Function
Origin
A humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Bisabolol
Est. %0.3
Function
Origin
An anti-inflammatory compound found naturally in German chamomile essential oil. It has a pleasant, sweet, and floral scent. Bisabolol also has soothing and anti-inflammatory properties but can cause an allergic reaction in more sensitive individuals.
Triethylhexanoin
Est. %0.3
Function
Origin
An occlusive and emollient ester of glycerin and a fatty acid. It is easily spreadable and does not leave a sticky after-feel.
Silica
Est. %0.3
Function
Origin
A widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Alumina
Est. %0.3
Function
Origin
A mineral derived from the metal ore known as aluminum. It is commonly used as an abrasive and also acts as a thickening viscosity controlling agent (and thus as a bulking agent). Alumina is also a great opacifier.
Propylene Carbonate
Est. %0.3
Function
Origin
A derivative of propylene glycol that is used most frequently as a solvent. Additionally, propylene carbonate serves as a viscosity controlling agent reducing the thickness of the products it is added to.
Ethylene/Methacrylate Copolymer
Est. %0.3
Function
Origin
Description is coming soon
Sorbitan Sesquioleate
Est. %0.3
Function
Origin
A natural liquid ingredient that is yellow to amber in color and completely transparent. It supports oil and water mixtures and disperses minerals into oils.
Caprylyl Glycol
Est. %0.3
Function
Origin
An emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
Stearic Acid
Est. %0.3
Function
Origin
A saturated fatty acid found in vegetable butter and animal fats. It is an occlusive moisturizing and emollient ingredient and also helps to maintain the barrier function of the skin.
Glycyrrhetinic Acid
Est. %0.3
Function
Origin
A compound derived from licorice root. It is a powerful anti-inflammatory ingredient with some anti-pigment properties.
PEG-40 Stearate
Est. %0.3
Function
Origin
This PEG, or polyethylene glycol, is excellent at emulsifying water and oil together to form oil-in-water emulsions. Due to its water-loving nature, PEG-40 stearate can also act as a cleansing agent.
Isopropyl Titanium Triisostearate
Est. %0.3
Function
Origin
Description is coming soon
Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate
Est. %0.3
Function
Origin
An antioxidant that protects vulnerable ingredients from the damage caused by ultraviolet radiation, which can also lead to the generation of damaging free radical species.
Mica
Est. %0.3
Function
Origin
A mineral powder made up of silicates with several functions (the main one being as a colorant). It has a shimmery appearance, making it highly desirable in certain cosmetic products. Mica also helps the product to apply more smoothly.
Titanium Dioxide (CI 77891)
Est. %0.3
Function
