In cosmetics, it is a multitasker:

Glyceryl Stearate is made by reacting glycerin with stearic acid (typically sourced from plant oils like palm or coconut). It's an emulsifier, emollient, and mild occlusive.

Emulsifiers help ingredients like oil and water stay mixed so your formula stays nicely blended and uniform in texture.

Synthetic beeswax is created to be identical in structure to beeswax. It possesses the same occlusive and emulsion properties.

A blend of fatty acid esters, fatty acids, and alcohols are used to create synthetic beeswax. Whether or not this ingredient is vegan depends on the source. Sometimes, lanolin is used for its creation.

Polyisobutene is a synthetic polymer made from isobutene.

It is a film-forming agent and helps bind ingredients together.

Kaolin is a clay. It is used for oil control and to help minimize pores. Like other clays, kaolin has the ability to absorb excess sebum or oil. This can help clean out pores and mattify the skin.

Some types of kaolin may have exfoliating properties. When water is added to kaolin, it becomes a paste with small abrasive particles.
