Ingredients explained

Isododecane

What-it-does: emollient, solvent

Aclear, colorless and odorless, highly volatile (meaning it does not absorb into the skin but evaporates from it) liquid that's used as an emollient. It gives a nicenon-oily light skin feeland it can improvethe slip of the formula without leaving a tacky residue behind.

It's also popular in make-up products as its volatility makes mascarasand foundations last longer. If that would not be enough, it's also an excellent solvent, and it's a regular not only on the ingredients lists of make-ups but also on makeup removers.

Trimethylsiloxysilicate

What-it-does: emollient

A solid silicone resin that creates a permeable film over the skin. It makes makeup formulas more long-lastingand can enhance the water resistance of sunscreens. It leaves a non-tacky film when dried.

Ci 77499 (Iron Oxides)

Also-called: Iron Oxide Black | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

Black Iron Oxide is thesuper common inorganic(as in no carbon atom in the molecule)pigmentthat controls the darkness of your foundation or gives the blackness to your mascara. Blended with red and black iron oxides, it is essential in all "flesh-toned" makeup products.

Chemically speaking, it is a mixture of iron II and iron III oxide. Btw, this guy, unlike the yellow and red pigments, is magnetic.

Dimethicone

What-it-does: emollient | Irritancy: 0 | Comedogenicity: 1

Probably themost common silicone of all. It is a polymer (created from repeating subunits) molecule and has different molecular weight and thus different viscosity versions from water-light to thickliquid.

As for skincare, it makes the skin silky smooth, creates a subtle gloss and forms a protective barrier (aka occlusive). Also, works well to fill in fine lines and wrinkles and give skin a plump look (of course that is only temporary, but still, it'snice). There are also scar treatment gels out there using dimethicone as their base ingredient. It helps to soften scars and increase their elasticity.

As for hair care, it is a non-volatile silicone meaning that it stays on the hair rather than evaporates from it andsmoothes the hairlike no other thing. Depending on your hair type, it can bea bit difficult to wash out and might cause some build-up (btw, this is not true to all silicones, only the non-volatile types).

Ci 77491 (Iron Oxides)

Also-called: Iron Oxide Red | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

Red Iron Oxide is the super common pigment that gives the familiar, "rust" red color. It is also the one that gives the pink tones in your foundation. Chemically speaking, it is iron III oxide (Fe2O3).

Synthetic Wax

What-it-does: emollient, viscosity controlling

Polyethylene

What-it-does: viscosity controlling

Polyethylene is the most common plastic in the world. It is a super versatile polymer (molecule from repeated subunits) and when it comes to cosmetics, it is often referred to as microbeads. Well,it used to be referred to as microbeads, as it wasbanned in 2015 in the "Microbead-Free Waters Act" due to the small plastic spheres accumulating in the waters and looking like food to fish. Well done by Obama.

But being versatile means that polyethylene does not only come as scrub particles but also as a white wax. In its wax-form, it is still well, alive and pretty popular. It thickens up water-free formulas, increases hardness and raises the meltingpoint ofemulsions and water-less balms. It is particularly common in cleansing balms and stick-type makeup products due to its ability to add body, hardness and slip to these formulas.

Polybutene

What-it-does: viscosity controlling

Ci 77492 (Iron Oxides)

Also-called: Iron Oxide Yellow | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

Yellow Iron Oxide is the super common inorganic (as in no carbon atom in the molecule) pigment that gives the yellow tones in your foundation. Blended with red and black iron oxides, it is essential in all "flesh-toned" makeup products.

Chemically speaking, it is hydrated iron III oxide and depending on the conditions of manufacture, it can range from a light lemon to an orange-yellow shade.

Ci 77891 (Titanium Dioxide)

Also-called: Titanium Dioxide/Ci 77891 | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

Ci 77891 is the color code of titaniumdioxide.It's a white pigment with great color consistency and dispersibility.

Silica

What-it-does: viscosity controlling, absorbent/mattifier

A white powdery thing that's the major component of glass and sand. In cosmetics, it’s often in products that are supposed to keep your skin matte as it has great oil-absorbing abilities. It’s also used as a helper ingredient to thicken up productsorsuspendinsoluble particles.

Polyglyceryl-4 Diisostearate/​Polyhydroxystearate/​Sebacate

What-it-does: emulsifying, emulsion stabilising, surfactant/cleansing

Caprylic/​Capric Triglyceride

What-it-does: emollient

A super common emollient that makes your skin feel nice and smooth. It comes from coconut oil and glycerin, it’s light-textured, clear, odorless and non-greasy. It’s a nice ingredient that just feels good on the skin, is super well tolerated by every skin type andeasy to formulate with. No wonder it’s popular.

Stearalkonium Hectorite

What-it-does: viscosity controlling

Alumina

Also-called: Aluminum Oxide, Al2O3 | What-it-does: viscosity controlling, absorbent/mattifier, abrasive/scrub

A multi-functionalhelper ingredient that's used mainly as a pigment carrier. The pigment can be an inorganic sunscreen(such as titanium dioxide) or a colorant that is blended withalumina platelets and then often coated with some kind of silicone (such as triethoxycaprylylsilane). This special treatment enables pigments to be evenly dispersed in the formulaand to be spread out easily and evenly upon application. It is super useful both for mineral sunscreens as well as for makeup products.

Other than that, alumina can also beused as an absorbent (sometimes combined with the mattifying powder called polymethylsilsesquioxane), a viscosity controlling or an opacifying (reduces the transparency of the formula) agent.

Magnesium Oxide

What-it-does: absorbent/mattifier, buffering

What-it-does: solvent, viscosity controlling

Tocopherol - goodie

Also-called: Vitamin E | What-it-does: antioxidant | Irritancy: 0-3 | Comedogenicity: 0-3

  • Primary fat-soluble antioxidant in our skin
  • Significant photoprotection against UVB rays
  • Vit C + Vit E work in synergy and provide great photoprotection
  • Has emollient properties
  • Easy to formulate, stable and relatively inexpensive
