Stearic Acid TEA
Also known as: Stearic Acid / Triethanolamine
What is Stearic Acid TEA?
A combination of stearic acid (an 18-carbon saturated fatty acid) with triethanolamine (TEA), which forms a soap-like emulsifier in situ.
Why is it used in products?
When stearic acid and TEA combine in a formula, they create a self-emulsifying base that produces stable, creamy lotions without additional emulsifiers.
Why does it clog pores?
The stearic acid component forms a waxy, occlusive layer over pores that traps sebum and dead cells. When combined with TEA, the resulting soap-like compound can also irritate the follicular lining. This dual action of occlusion and irritation makes it problematic for acne-prone skin.
