Sulfates
Sulfates are common ingredients used in beauty and personal care products that help create lather and clean effectively. They're most often found in shampoos, body washes, and cleansers. In recent years, many brands have moved towards "sulfate-free" formulations as some consumers prefer gentler alternatives. When reading resumes in the cosmetics industry, you'll often see references to sulfates in the context of product development, formulation, or marketing claims. Think of sulfates like a cleaning powerhouse - they're effective at removing dirt and oil, but some consider them too strong for sensitive skin or colored hair.
