The hydrolysed starch may be maltodextrin.

More preferably the active ingredient comprises at least one suitable pharmaceutical active ingredient, cosmetic active ingredient, toiletries active ingredient and/or any compatible mixture thereof. Most preferably the active ingredient comprises a moisturiser or a pigment. Anhydrous and hydrophobic non-oral compositions comprising the powder are described as are methods of preparing them. Preferably the compositions are suitable for topical application, more preferably they comprise a lipstick or talcum powder. The compositions may also exhibit synergistically enhanced delivery.
