A cosmetic composition particularly a hair wash formulation/ composition, in powder form is disclosed comprising a synergistic combination of anionic surfactant with cationic polymers, starch and silicone emulsion in a suitable inorganic carrier / filler that is adapted to deliver superior conditioning benefits of significantly improved foam, cleansing, softness of hair while wet. Said formulation/ composition as a free flowing powder form with extended shelf life is selectively achieved in combination with selective powdered inorganic materials adapted as suitable carriers of the silicone emulsion in presence of starch to thus favour extended shelf life of the composition as a free flowing powder, which in addition imparts softness and shine to the hair after applying and drying of the hair favouring ease of combing of dry hair and making hair manageable.
