GRWM Cosmetics Powder Rush Loose Baking & Setting Powder Ultra Blur
Ingredients explained

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 products or suspend insoluble particles. 

What-it-does: absorbent/mattifier, abrasive/scrub | Irritancy: 0 | Comedogenicity: 1

Talc is the major component of most powder makeup products (think face powder, eyeshadows, and blushers) that usually contain it up to 70%. Its two winning properties that make it very suitable for this role is its outstanding spreadability for a smooth application and its low covering power, aka translucency to avoid clown-like effects.

Chemically speaking, it is a clay mineral (hydrated magnesium silicate) that is mined in several countries. The drawback of mined minerals is potential impurities and the version used in cosmetics has to be white (not gray like cheaper grades), free from asbestos, sterilized and have thin plates for a maximum slip. 

A handy helper ingredient that comes in a white powder form and works as an anti-caking and oil-absorbing agent. It also gives products good spreadability, long lasting and velvet touch characteristics. It is popular both in skincare and makeup products.

What-it-does: emollient

Bearing a close relationship to the famous Dimethicone, Methicone is the slightly trimmed down version missing the methyl (-CH3)  groups on one side of the silicone chain. Like most silicones, it has nice emollient properties and improves the spreadability of products.

But Methicone's main thing in practice is not being an emollient but a silicone fluid for hydrophobization treatment of powders, i.e. making solid powders (mineral filters & color pigments) very water resistant and easily spreadable. Methicone does this by absorbing traces of water from the surface of pigments that is very useful for mineral sunscreens and makeup products. 

What-it-does: anti-acne, soothing, deodorant

If you are fighting acne and have looked into oral supplements, chances are that zinc gluconate sounds familiar to you. It is a zinc salt that has research proving it to be effective against inflammatory acne, though not quite as effective as the antibiotic minocycline (31.2% vs. 63.4% success rate). However, zinc supplements are easily available, have little-to-no side effects, so supplementing them with a 30mg per day dose can still be a good idea.

As for smearing zinc gluconate all over your face, it is also not a bad idea. Zinc has multiple magic abilities: it is antibacterial (including evil, acne-causing P. acnes) and sebum-regulating (5α-reductase inhibitor), great for acne-prone skin types. It also stimulates antioxidant enzyme systems (mainly superoxide dismutase) and has nice wound healing abilities acting mainly in the first, proliferation phase. So great for skin types in need of healing and soothing.

What-it-does: preservative

It’s pretty much the current IT-preservative. It’s safe and gentle, but even more importantly, it’s not a feared-by-everyone-mostly-without-scientific-reason paraben.

It’s not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic.

Also-called: Castor Oil | What-it-does: emollient, perfuming | Irritancy: 0 | Comedogenicity: 0-1

Castor oil is sourced from the castor bean plant native to tropical areas in Eastern Africa and the Mediterranean Basin. It is an age-old ingredient (it’s over 4,000 years old!) with many uses including as a shoe polish, food additive and motor lubricant. You would be reasonable to think that putting shoe polish on your face wouldn’t be the best idea, but it turns out castor oil has some unique properties that make it a stalwart in thick and gloss-giving formulas (think lipsticks and highlighters).

So what is so special about it? The answer is its main fatty acid, called ricinoleic acid (85-95%).  Unlike other fatty acids, ricinoleic acid has an extra water-loving part (aka -OH group) on its fatty chain that gives Castor Oil several unique properties. First, it is thicker than other oils, then its solubility is different (e.g. dissolves in alcohol but not in mineral oil), and it allows all kinds of chemical modifications other oils do not, hence the lots of Castor oil-derived ingredients. It is also more glossy than other oils, in fact, it creates the highest gloss of all natural oils when applied to the skin. Other than that, it is a very effective emollient and occlusive that reduces skin moisture loss so it is quite common in smaller amounts in moisturizers. 

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

It’s the most commonly used version of pure vitamin E in cosmetics. You can read all about the pure form here. This one is the so-called esterified version. 

According to famous dermatologist, Leslie Baumann while tocopheryl acetate is more stable and has a longer shelf life, it’s also more poorly absorbed by the skin and may not have the same awesome photoprotective effects as pure Vit E.

What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

It’s the - sodium form - cousin of the famous NMFhyaluronic acid (HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here.  The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water.

As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephen writes on reddit  "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution". 

What-it-does: preservative, deodorant

If you have spotted ethylhexylglycerin on the ingredient list, most probably you will see there also the current IT-preservative, phenoxyethanol. They are good friends because ethylhexylglycerin can boost the effectiveness of phenoxyethanol (and other preservatives) and as an added bonus it feels nice on the skin too.

Also, it's an effective deodorant and a medium spreading emollient

Phospholipids - goodie

A type of lipid that's the major (about 75%) component of all cell membranes. As for skincare, it works as an emollient and skin-identical ingredient.

It has a water-loving head with two water-hating tails and this structure gives the molecule emulsifying properties. It is also often used to create liposomes, small spheres surrounded by phospholipid bi-layer designed to carry some active ingredient and help its absorption.

What-it-does: emollient, viscosity controlling | Irritancy: 2 | Comedogenicity: 1

A synthetic liquid oil that can replace mineral oil or silicone oils in the cosmetic formulas. There are different grades depending on the molecular weight ranging from very light, volatile, non-residue leaving ones to more substantial, slight residue leaving ones.

Apart from leaving the skin soft and smooth (emollient), it's also used as a waterproofing agent in sunscreens or makeup products and as a shine enhancer in lip gloss formulas. 

What-it-does: emollient, viscosity controlling, emulsifying, surfactant/cleansing | Irritancy: 0 | Comedogenicity: 1

A chemically modified version of castor oil that results in a solid, waxy material that serves as an emollient and consistency building material.

It also has some unique moisturizing properties as it is both occlusive and humectant.  The former one is common for oils and waxes and it means that it sits on top of the skin hindering water to evaporate out of the top layers. The latter one, the humectant property, is surprising and comes from the unique property of ricinoleic acid (the dominant fatty acid in castor oil)  having an extra water-loving -OH group on its otherwise oil-loving fatty chain. We have some more info about this at castor oil, so if you are interested, read on here.  

Ceramide NP - goodie
Also-called: Ceramide 3 | What-it-does: skin-identical ingredient

One of the many types of ceramides that can be found naturally in the upper layer of the skin. Ceramides make up about 50% of the goopy stuff that's between our skin cells and play a super important role in having a healthy skin barrier and keeping the skin hydrated. It works even better when combined with its pal, Ceramide 1.

We wrote way more about ceramides at ceramide 1, so click here to know more.

Also-called: Red 40 | What-it-does: colorant | Irritancy: 2 | Comedogenicity: 2
