Sodium stearoyl lactylate is primarily used for its emulsifying and stabilizing properties in food and cosmetics. In food, SSL mixes water and oil together and mostly used as a dough strengthener and crumb softener in bakery; in cosmetics, it is a viscosity enhancer and conditioner.

Food
SSL is mainly used in high fat & yeast-leavened bread as a dough conditioner/emulsifier for the purposes of:

dough strengthening: increase volume and obtain a better crumb structure
crumb softening: interacts with flour to form gluten proteins/starch/lactylate complex which produce a soft and elastic bread and prevents bread retrogradation (aging)

If without SSL, the loaf will become hardened.

It is also used in cookies, crackers, pastries, noodles, and the like to improve the texture, mouthfeel and prolong the freshness or shelf time. In cookie and cracker, SSL is used to distribute shortening uniformly in the dough.

SSL can be directly added to flour or dispersed in warm water and then blended with flour for use.

Whipped toppings and desserts (an aerating agent)
Non-dairy coffee creamers (a complexing agent stable the emulsion)
Whitening powder ( a fat replacer)
