Is Sensitive Laundry Liquid septic and greywater safe?
✓ Why it's septic and greywater safe
Sensitive Laundry Liquid is free from phosphates (which can disrupt septic systems and cause algal blooms in waterways), dyes (extra chemicals in wastewater for no cleaning benefit), and VOCs (compounds that can harm aquatic life). The biological enzymes break down naturally in septic and greywater environments.
✓ Where it works well
Suitable for rural properties on septic tanks, off-grid properties using greywater reuse systems, and mobile setups like caravans, camper vans, motorhomes, and boats. Always use the recommended dose, follow your septic system manufacturer's guidance, and check local council rules for greywater reuse in your area.
Around 60 washes per box. Sensitive Choice approved, Dermatest tested. Septic and greywater safe.
