Sulfates are common surfactants widely used in personal care products for over a century. Composed of hydrophilic and lipophilic groups, they attract both water and oil, and are commonly used in soaps, shampoos, and other cleansers. Sulfates play a crucial role in the cleansing process, but overuse can irritate the skin.
The cleansing effect of sulfates is achieved through the combined action of their hydrophilic and lipophilic groups. Imagine a sulfate as a cotton swab, one end absorbing oil, the other absorbing water. During use, the oil-absorbing end adheres to oil and makeup, while the water-absorbing end binds with water, carrying the oil away from the skin's surface, thus completing cleansing tasks such as makeup removal.
While sulfates are safe and effective in cleansing, overuse can damage the skin. Especially for sensitive skin or scalps, sulfates may cause adverse reactions such as redness, itching, and excessive dryness. Therefore, we recommend reducing the frequency and amount of sulfate surfactant use.
