A plant- and mineral-based fabric softener from ATTITUDE, scented with citrus peel — 40 washes per bottle.
How fabric softener actually works, which explains everything else about it. Softeners are built on cationic surfactants: positively charged molecules that are attracted to the negatively charged surface of wet fabric and deposit there, coating each fibre with a thin waxy film. That film is what makes cotton feel soft, what reduces static, and what makes ironing easier — all real effects, produced by a coating rather than by any change to the fibre itself.
Which is also why there are things you should never use it on. A coating that repels water is exactly what you do not want on a towel: softener is the single commonest cause of towels that stop absorbing, and the effect accumulates wash after wash. The same applies to microfibre cloths, which work by capillary action, and to technical sportswear and waterproof shells, where the film blocks the moisture-wicking or the breathable membrane. And it should never be used on flame-retardant children's sleepwear, because the coating can compromise the treatment. These are not fussy caveats — they are the four cases where softener does measurable harm.
Where it genuinely earns its place: cotton bedding, shirts, and anything that goes through a tumble dryer in a dry climate where static is a nuisance. On those, it does exactly what it claims.
An honest suggestion. If you are trying to simplify your laundry cupboard, fabric softener is the product most households can drop with the least loss — and half a cup of white vinegar in the rinse compartment removes detergent residue, softens water and reduces static without coating anything. It does not leave a scent. We would rather tell you that than not.
Citrus peel scent comes from the essential oils in the rind rather than a synthetic fragrance — which is a real difference in ingredient, though natural aromatics are still potential allergens. If anyone in the house has eczema, choose an unscented product.
