Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinGlyceryl Stearate SE is a self-emulsifying (SE) form of Glyceryl Stearate. It comes with a small amount of soap (usually potassium or sodium stearate) that gives it the "SE" part.
That soap lets it pull oil and water together on its own which is why it shows up as an emulsifier, thickener, and emollient.
Industry survey data shows this ingredient is used around 1-5% but Glyceryl Stearate goes as high at 17% in a leave-on deodorant.
Safety-wise, it's pretty boring: it's been deemed safe for topical use in 1982 and again most recently in 2021 by the CIR. Human repeat insult patch tests come back non-irritating, non-sensitizing, non-phototoxic, and non-photoallergenic.
This ingredient does carry a comedogenic rating of 3 from the old rabbit-ear assay. Just remember testing finished products in humans showed that formulas built with "comedogenic" ingredients are not necessarily comedogenic themselves. It's worth patch testing if you're breakout prone, and always listen to your skin.
The Malassezia yeast can potentially metabolize the stearic acid in this ingredient, so it may not be fungal acne safe.
Allergy is rare: a 310-patient patch test study of common emulsifiers found this ingredient was not a meaningful reactor. Isolated case reports do exist so a true contact allergy is possible but uncommon.

In skincare, it is an:
Research indicates that this ingredient posts a low risk of irritation and sensitization.
Since myristic acid is a C14 fatty acid, it falls within the range that Malassezia can metabolize, and therefore not fungal acne safe.

According to a manufacturer, it is a non-paraben and specially developed for negatively charged surfactant systems. This makes it a great hairstyle holder and helps to improve wet hair detangling without adding buildup.
Potassium Hydroxide (also known as potash) is a strong alkaline ingredient that does one job: it nudges a product's pH up so the whole formula lands in a skin-friendly range.
It's also the base that turns oils into liquid soap during the soap making process.
An expert safety panel reviewed it and found it safe when formulations are made to be non-irritating.
As a pH adjuster, it's typically used well under 1% though regulatory caps go much higher: 5% in nail cuticle removers and 2-4.5% in hair straighteners.
Though there is some concern for irritation from raw or high pH material, a well-balanced formula will be a non-issue for the vast majority of people.

In cosmetics, it is a multitasker:
Safety-wise, the CIR Expert Panel has concluded it to be safe in cosmetics when formulated to be non-irritating and non-sensitizing.
Free stearic acid is a C18 fatty acid that the Malassezia yeast can substrate, so this ingredient may not be fungal acne safe.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
