Isotridecyl stearate absorbs very quickly into the skin, leaves no shine and gives a nice, velvety after-feel.
Isotridecyl stearate is used in cosmetics as a thickening agent and emollient.
May be synthetic or animal-derived.

The stearate esters (Butyl Stearate, Cetyl Stearate, Isocetyl Stearate, Isopropyl Stearate, Myristyl Stearate, Ethylhexyl Stearate, Isobutyl Stearate) are oily liquids or waxy solids. 
Ethylhexyl Stearate may also be called Octyl Stearate. 
In cosmetics and personal care products, stearate esters are used most frequently in the formulation of eye makeup, skin makeup, lipstick and skin care products.

Stearate esters act primarily as lubricants on the skin's surface, which gives the skin a soft and smooth appearance. 
Butyl Stearate also decreases the thickness of lipsticks, thereby lessening the drag on lips, and imparts water repelling characteristics to nail polishes. 

Butyl Stearate and Isopropyl Stearate dry to form a thin coating on the skin. 
Isocetyl Stearate can also be used to dissolve other substances, usually liquids.

Scientific Facts: 
The stearate esters are prepared by reacting stearic acid with the appropriate alcohol (butyl, cetyl, isobutyl, isocetyl, isopropyl, myristyl or ethylhexyl alcohol). 
Stearate esters have the unique properties of low viscosity and an oily nature, which results in a nongreasy, hydrophobic film when applied to the skin or lips. 
Stearic acid is found in animal and vegetable fats.

Properties of Isotridecyl stearate:
Isotridecyl stearate is a lubricity additive, provides a substantially lubricious film,
