Propanediol
Est. %4
Function
Origin
An excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.

Est. %0.3
Function
Origin
A naturally-derived emollient ester. It is a blend of caprylates and caprates and, relative to other emollients, is lightweight and dry on the skin. As a result, coco-caprylate/caprate serves as a natural alternative to volatile silicones.

Est. %0.3
Function
Origin
A mineral derived from the metal ore known as aluminum. It is commonly used as an abrasive and also acts as a thickening viscosity controlling agent (and thus as a bulking agent). Alumina is also a great opacifier.
Polyhydroxystearic Acid
Est. %0.3
Function
Origin
A soft and malleable amber wax naturally derived from vegetable sources. It allows minerals to be very finely dispersed, which can improve SPF, decrease the white cast in sunscreens, and increase the color expression in pigmented products.
Cellulose
Est. %0.3
Function
Origin

Butylene Glycol
Est. %0.3
Function
Origin
A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Aluminum Hydroxide
Est. %0.3
Function
