Typical overall surfactant levels in liquid laundry and hard-surface cleaners can range from about 5–25% active matter depending on whether the product is a concentrate or ready-to-use. Higher concentrations can improve cleaning but may increase viscosity, foaming and cost, and may require careful selection of hydrotropes and foam-control agents. Regulatory limits, label claims and compatibility with other ingredients must also be considered, so we recommend lab trials and consultation with our technical experts.
