Most kaolin is a white color, but may be pink/orange/red depending on where it comes from.

The name 'kaolin' comes from a Chinese village named 'Gaoling'. Kaolin clay comes from rocks rich in kaolinite. Kaolinite, the mineral, has a silicate layered structure. Kaolinite is formed from chemical weathering of aluminum siilicate minerals.

Besides skincare, kaolin is commonly used to make glossy paper, in ceramics, toothpaste, and as medicine to soothe stomach issues.

There's no published concentration use from surveys so the best available numbers are supplier guidance: 5-10% for loose powders and 2-5% for creamy cosmetics + pressed powder binding.

The CIR Expert Panel reviewed Magnesium Myristate as part of its assessment of myristic acid and its salts and esters, and concluded the whole group is safe as used in cosmetics.

In human studies, Myristic Acid was non-irritating up to 50% and 100% Magnesium Stearate was non-irritating and non-corrosive on skin and non-irritating to the eye.

There are no published contact allergy case reports for this ingredient so allergy risk is low, but not zero for any ingredient.

There is no comedogenic data for Magnesum Myristate. The comedogenic ratings that circulate for "myristates" come from Isopropyl Myristate which is a structurally different ester.

The rabbit-ear models those comedogenic ratings come from have been shown to be unreliable for predicting whether a finished product will clog pores.

Human testing has proved that any finished product with a comedogenic ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.

Some people still find it breaks them out. So if that's you, definitely trust your skin.

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.

A 2021 paper looked at skincare formulations containing iron oxides and found that they reduced transmission of blue light when measured optically. In simple terms, the pigment particles helped block or scatter part of the visible light spectrum in lab testing and the authors suggest this could translate into better protection against blue-light-related skin effects.

There is also clinical and experimental research showing that tinted products containing iron oxides can reduce visible light-induced pigmentation:

Please note, whether a product reduces visible or blue light depends on things like:

In the EU's CosIng database, iron oxides are only listed as a colorant. CosIng groups ingredients by their main cosmetic role, such as colorant, preservative, or UV filter.

Though studies say iron oxides can "attenuate blue light", they're describing an optical property and not an officially recognized cosmetic function.

So CosIng isn’t contradicting the research. It’s just classifying iron oxides by what they officially are: pigments that add color.
