This guide explains how surfactants help water interact with oils and soils, and where the term appears on cleaning labels.
How surfactants work
Surfactants change how water interacts with oils, soils, and surfaces. This helps loosen and suspend dirt so it can be rinsed away.
Different classes
Anionic, nonionic, cationic, and amphoteric surfactants have different electrical properties and uses. A finished detergent can combine more than one class.
Environmental differences
EPA notes that surfactants differ in aquatic toxicity, biodegradation rate, and degradation products. A product-level environmental claim requires more than identifying one ingredient.
What to check before you choose a product
Read the directions, dose, washer compatibility, fragrance information, and ingredient disclosure when available. Compare the finished product instead of choosing from one front-label phrase.
