Abstract: 1. A detergent composition comprising: (a) 10 to 60% by weight of a synthetic, non-soap detergent, or mixture of synthetic non-soap detergents; (b) greater than 10% to 60% by weight of a water-soluble polyalkyleneglycol detergent and which has a melting point in the range 40 degree  to 100 degree C; (c) 0.01 to 10% by weight polyalkyleneglycol or mixture of polyalkyleneglycols which (polyalkyleneglycol or mixture of polyalkyleneglycols) has a melting point below about 40 degree C; (d) 5% to 50% by weight of a water insoluble structurant which is selected from C12-C24 fatty acids and C8-C20 alkanol and has a melting point in the range 40 degree  to 100 degree C; (e) 1 to 14% by wt. water; (f) 0 to 25% water soluble starch; and (g) 0 to 10% salt of a C8-12-monocarboxylic acid. 2. A composition as claimed in claim 1, wherein component (a) comprises at least one anionic surfactant, zwitterionic surfactant or mixtures thereof. 3. A composition as claimed in claim 2, wherein (i) said anionic component comprises acylisethionate, alkali metal alkylethersulfate or mixtures thereof, or (ii) said amphoteric comprises a betaine, an amidobetaine, a sulphobetaine or mixtures thereof. 4. A composition as claimed in claim 3, wherein acylisethionate comprises 10% to 40% of the said composition. 5. A composition as claimed in claim 3 or 4, wherein said amphoteric comprises 1% to 10% of said composition. 6. A composition as claimed in any preceding claim, wherein said detergent or mixture of detergent comprises greater than 20% of said composition. 7. A composition as claimed in any preceding claim, wherein said water-soluble structurant (b) has a melting point in the range 45 degree  to 100 degree C; 8. A composition as claimed in any preceding claim, wherein said water-soluble structurant (b) has a melting point in the range 50 degree  to 90 degree C; 9. A composition as claimed in any preceding claim, wherein said water-soluble structurant (b) is polyethyleneglycol having molecular weight greater than 1500 to 20000. 10. A composition as claimed in claim 9, wherein said water-soluble structurant (b) additionally comprises 1-5% polyalkylenglycol having molecular weight greater than 50000 to 500000. 11. A composition as claimed in any preceding claim, comprising greater than 10% to 50% water-soluble structurant. 12. A composition as claimed in any preceding claim, comprising greater than 10% to 40% water-soluble structurant. 13. A composition as claimed in any preceding claim ,wherein component (c) is a polyethyleneglycol having molecular weight of 100 to 1000 or a mixture of polyethyleneglycols with molecular weight from 100 to about 1500. 14. A composition as claimed in any preceding claim, wherein component (d) is a C12-C24 fatty acid. 15. A composition as claimed in any preceding claim, comprising 1 to 10% water. 16. A composition as claimed in claim 15, comprising 2 to 8% water. 17. A composition as claimed in any preceding claim, wherein said starch is maltodextrin. 18. A composition as claimed in any preceding claim, wherein component (g) is sodium stearate.
