Molly's Suds Original Laundry Detergent Powder is designed to offer a powerful clean with minimal ingredients, making it especially suitable for those with sensitive skin and environmental concerns. The detergent uses only four simple, stain-fighting ingredients, making it free from harsh chemicals such as synthetic fragrances, dyes, and formaldehyde. This simplicity is beneficial for those looking to avoid skin irritations and reduce their environmental footprint. The unscented formula is a plus for those who are sensitive to artificial scents or prefer a neutral smell in their laundry. It also offers a lightly scented option for those who desire a bit of fragrance.

Each 79 oz bag provides enough powder to clean up to 120 loads, indicating excellent concentration and value for money. A single tablespoon-sized scoop is sufficient for most loads, which speaks to its efficiency.

Additionally, it is septic and greywater safe, further underscoring its environmentally friendly credentials. The product is cruelty-free, adding an ethical dimension to its appeal.
