Skintific Panthenol Gentle Gel Face Wash Versus Luxe Organix Whitening Repair Foam Cleanser

On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it.

One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin).

Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption.

You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%.

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.

Rinse-off concentrations typically range from 2-25%.

The finished product sits at a fairly high pH (~9-11) because it's a true soap. This just means it can feel drying or slightly stripping if a formula isn't balance with emollients.

Allergy and irritation risk is low as this ingredient was found to be an irritant in less than 1% of subjects (2 of these subjects had active psoriasis and 3 had active eczema).

Fungal acne: The Malassezia yeast feeds on fatty acids in the ~C12-24 range, and Potassium Cocoate is made of exactly those (Lauric C12, Myristic C14, Palmitic C16, Oleic C18:1). Lab studies have shown the yeast can take up Lauric Acid and grows readily on Palmitic Acid. Therefore, this ingredient may not be fungal acne safe.
