This is a biological laundry detergent designed to provide a deep clean while being gentle on fabrics. Its concentrated formula is effective even at low temperatures due to the inclusion of enzymes that help break down stains and dirt. The detergent also contains natural ingredients, including an ethically sourced palm oil-derived surfactant, sodium carbonate, and sodium citrate. These components enhance cleaning performance, reduce water usage, and help minimise environmental impact.
This product has been recognised as an Ethical Consumer Best Buy for its strong environmental credentials, highlighted for its refill-friendly supply chain. It adheres to SESI’s minimalist ingredient philosophy and has been reformulated to eliminate phenoxyethanol, further decreasing reliance on synthetic preservatives. Balancing effective cleaning with a reduced environmental impact, this is a reliable choice for households looking for a more sustainable everyday detergent.
The fragrance is characterised as a "fresh cologne" style scent, featuring natural extracts of patchouli, lemon, cedarwood, and eucalyptus. These notes blend to create a clean and uplifting aroma, highlighted by the bright citrus scent of lemon. This is balanced by the warm, woody aroma of cedarwood and the soft herbal nuances of eucalyptus, complemented by a subtle earthy richness from patchouli. The overall effect is fresh, natural, and not overpowering, making it ideal for use on clothes, towels, or linens when you desire a crisp scent without the harshness of synthetic perfumes. This product is also available in an unfragranced version.
All SESI products are vegan, cruelty-free, and biodegradable, and their formulas are designed to truly clean while causing minimal environmental harm. The detergents are manufactured in the UK by an independent family firm.

SESI Refills is a UK-based social enterprise founded in Oxfordshire, which supplies sustainable detergents, toiletries and household cleaning products. Originally known as the School Ethical Supplies Initiative, SESI was started in 2006 in a shed at a local primary school.
Their products do not contain harsh or harmful ingredients, including chlorine bleaches, formaldehyde, phosphates, parabens, phthalates, optical brighteners, and other damaging chemicals. Their products are also safe for septic tanks and normal wastewater systems. They are an Ethical Consumer Best Buy with an ethiscore of 95 out of 100.
♻️ Closed Loop supply chain ♻️
SESI employs a closed-loop refill system, meaning that barrels and tubs used for distribution are returned, cleaned, and refilled. This process ensures that there is zero packaging waste from the factory to the consumer. Every time we order SESI products, they are sent to us directly from their factory using their own vehicles, resulting in a greatly reduced carbon footprint. With each delivery, we receive filled bulk bottles (that you fill your own bottles from to take home), which means your refills are truly zero waste!
In addition to cleaning detergents and household products, SESI also supplies food items and olive oil through a refillable supply chain. For example, they partner in a closed-loop supply of Extra Virgin Olive Oil, utilising bulk 20 litre tubs. These broader product offerings increase the impact of refill shopping by enabling more types of goods to be supplied to us through a circular supply chain and helping customers reduce plastic waste across more categories.
Through their refill model, SESI helps customers reduce plastic waste: they have reused or refilled over 5 million pieces of packaging to date.
