Abstract: For a container (1) with a reservoir (2) to collect a product (3) and a dispensing device (4), which is equipped with an opening (5) to dispense a flowable agent, particularly a powdery or granular product (3) dissolved and/or dispersed in a liquid (8), wherein said dispensing device is connected to the reservoir (2), a device (7) with passages (10) is used to hold back excessively large particles of the product (3), so that wholly undissolved product (3) and/or excessively large particles and/or poorly dispersed particles cannot reach the opening (5) of the dispensing device (4) and thereby cannot block the opening (5). To achieve secure protection of the opening against a blockage, it is proposed that the diameter (1) or the minimum width (12) of the passages (10) is from 0.5 mm to 5 mm and is less than or equal to the diameter (13) or the minimum width of the opening (5) (FIG. 7).

Abstract: Compositions suitable for dyeing and bleaching hair comprising a phosphate ester compound and an oxidizing agent. The phosphate ester compound preferably comprises a mixture of monoester phosphates of alkoxylated fatty alcohols containing from about 12 to about 22 carbon atoms with diester phosphates of non-alkoxylated fatty alcohols containing from about 12 to about 22 carbon atoms. Preferably the compositions are in the form of oil-in-water emulsions. The compositions have good rheologies and improve the bleaching and dyeing of hair.
