This will be boring for some of you, so apologies. But I'll post it in case anyone does have an interest in the ingredients.
Molton Brown products are cleverly marketed and not very good quality. They give me eczema. If you look at the ingredients lists, they are chock full of cheap chemicals and, quite often, very small amounts of natural ingredients. They play up the natural element on the packaging, but the natural ingredients come way down the list of ingredients.
The Naran Ji hand wash ingredients are as follows: Water (Aqua), Sodium Laureth Sulfate, Cocamide DEA, Propylene Glycol, Fragrance (Parfum), Citrus Aurantium Dulcis (Orange) Peel Oil, Citrus Grandis (Grapefruit) Fruit Extract, Glycerin, PEG-40 Hydrogenated Castor Oil, Amyl Cinnamal, Eugenol, Hexyl Cinnamal, Hydroxycitronellal, Limonene, Linalool, Methylisothiazolinone, Phenoxyethanol, Citric Acid, PEG-18 Glyceryl Oleate/Cocoate, Sodium Chloride.
I don't know how many of you look into cosmetic ingredients before buying, but that list is shockingly cheap and nasty for the price.
Someone mentioned Liz Earle's handwash- that or Neal's Yard's one are similarly priced but without all the crap.
In summary, let the builders use it up, then buy one that isn't filled with chemical crap.
