The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.

The invention relates to a synthesis method for cationic bleaching activating agents with surface activity, belonging to the field of fine chemical engineering. According to the method, a series of cationic bleaching activating agents with different carbon chain-length quaternary ammonium salt groups are synthesized by adopting alkyl dimethyl tertiary amine, 4-(chloromethyl)benzoyl chloride and lactam as intermediates. The leaching activating agent has stronger affinity on the surface of a material with surface electronegativity in an aqueous solution, can react with hydrogen peroxide on the surface of the material to produce extremely active peroxy acid, can bleach the material at a low temperature so as to effectively remove the pigment impurities on the surface of the material. The cationic bleaching activating agent can be used for industrial bleaching and household washing of textiles.
