I am looking for name of those polymers which are used in manufacturing of cosmetics products?

Thickening agents such as polymers are often added to cosmetics to change their consistency. Polymers can be synthetic (eg, polyethylene glycol) or derived from natural sources (eg, polysaccharides). Seaweeds are a common source of natural polysaccharides 鈥?carrageenans are extracted from red algae and alginates from brown algae. Cosmetics that are too thick can be diluted with solvents such as water or alcohol.
