Ingredients Explained
Propylene Glycol is a synthetic, colorless, odorless liquid that has been a staple in cosmetics for decades. It is a skin conditioning agent, humectant, and solvent.
As a humectant, it draw water to the skin to reduce flaking and restore suppleness. It's also a solvent that helps dissolve other actives and keeps formulas stable across temperature changes.
The CIR Expert Panel has confirmed this ingredient to be nontoxic and clinical studies show no sensitization at cosmetic use concentrations.
True allergic reactions are quite rare: a 15-year retrospective study of 6,751 patients found only 0.31% had a positive reaction (and less than half were considered clinically relevant).
It seemed that when sensitization does occur, it's most commonly linked to topical medication (like corticosteroids) and not cosmetics. Allergic contact dermatitis also appears largely limited to individuals with underlying skin conditions.
Overall, propylene glycol is a well-studied ingredient that most people can tolerate without issue.

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!
Learn more about WaterSodium stearate is the sodium salt of stearic acid.
The structure of sodium stearate makes it both a cleanser and emulsifier. As a cleanser, it helps dissolve dirt, oil, and other pollutants. As an emulsifier, it helps prevent ingredients from separating. This adds stability to the formula.
Octyldodecanol is a fatty alcohol sourced from plant oils like coconut or palm (or made synthetically).
It is:
You'll likely see this in many BHA products because this is the go-to solvent for salicylic acid.
This ingredient is typically used at levels between 2-20%.
Regarding fungal acne:
In 2019, this ingredient was tested against multiple Malassezia species (the yeast that causes fungal acne) and showed no growth.

This ingredient comes from a medicinal mushroom commonly used in East Asian medicine. It has skin conditioning properties. It is also known as Wolfiporia extensa.
It is particularly great at soothing inflammation and protecting skin from stress due to its high content of polysaccharides and triterpenoids.
Some studies link the triterpenes to reduced oxidative stress and collagen protection in skin models. This suggests potential benefits for early signs of aging.
On top of that, studies also report tyrosinase inhibition and reduced melanin production in melanocyte models to help brighten skin (though more clinical evidence is needed for definitive claims).
The polysaccharides can also help hydrate the skin as humectants.
Safety data shows a low irritation risk for this ingredient. However, like any extract, some may experience an allergic reaction when using this ingredient. Be sure to patch test!

Tetrasodium Glutamate Diacetate is a chelating agent. Chelating agents help prevent metal ions from binding to other ingredients. This helps prevent unwanted effects and reactions from a product. These metal ions may come from water and are found in miniscule amounts.
Tetrasodium Glutamate Diacetate can also help other preservatives be more effective.
Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.Â
It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.
