How does Stearyl Alcool work chemically?

The molecule is a saturated C18 linear alcohol with a melting point around 58 to 60 °C, which helps build viscosity and crystalline structure in emulsions. Typical use levels are about 0.5 to 5% in creams and lotions, it is nonionic and broadly pH-stable, and it is more oxidation-resistant than unsaturated lipids.
