Definitions

  • the present invention relates to detergent compositions in non-particulate form. More particularly, the invention relates to a process for improving the aesthetics of detergent compositions in non-particulate form, e.g., tablet, block or bar, by improving the neat product odor of a non-particulate detergent and also enabling the delivery of different fragrances to a non-particulate detergent product as compared to the odor delivered to the laundry by a perfume incorporated within the detergent, by using electrostatic techniques.
  • Non-particulate solids detergents are an alternative to granular or paniculate forms of detergents for simplifying the dosing of such detergents for automatic laundry or dishwashing washing machines.
  • Such non-particulate detergents are usually supplied in the form of bars or tablets or briquettes.
  • Such non-particulate detergents not only prevent spillage of the detergent composition but also eliminate the need for the consumer to estimate the correct dosage of the detergent composition per wash. Further, such non-particulate detergents also minimize the contact by the consumer with the detergent.
  • non-particulate detergent An important factor for successful performance of a non-particulate detergent is its ability to dissolve in the washing machine in a controlled manner according to a desired dissolution profile during the program cycle of the machine. Another important performance factor is that the non-particulate detergent should be hard enough to facilitate easy handling of the detergent prior to use, so that it does not inadvertently lose its structure, crumble, or deteriorate, both during the packaging, transport and storage and during handling by the end consumer prior to actual use. Such performance aspects are an important feature of the non-particulate detergent, 2
  • a very desirable feature of a non-particulate detergent is its appearance and odor. From an aesthetics standpoint, consumers prefer to use detergent tablets that have a fragrant odor. It is thus desirable to improve the neat product odor of detergent tablets.
  • most detergent compositions include a perfume incorporated within the detergent.
  • the tablets are occasionally encapsulated by a protective coating. This coating can substantially mask the odor of the perfume incorporated within the detergent. By dusting the tablet with a perfume carrier, one can improve the neat product odor and make the tablet detergent product more aesthetically pleasing.
  • the deposition of a perfume carrier coating on a detergent tablet enables the delivery of different fragrances to the detergent tablet product as compared to the odor delivered to the laundry by a perfume incorporated within the detergent composition.
  • a laundry detergent tablet with a core which is formed by compressing a paniculate material, the paniculate material having a surfactant and detergent builder, which is coated with a perfume in order to improve its odor. It is also desirable to provide a laundry tablet with a hard, thin, coating which has a perfume coating deposited on it, so that the laundry tablet has a pleasant odor, it can be stored, shipped and handled, but the coating is broken when the tablet is in the washing machine exposing the soft core which breaks up easily and rapidly, releasing the active ingredients into the wash solution. Thus, it is highly desirable to improve the neat product odor of a non- particulate detergent. It is also highly desirable to have a process for providing a non-particulate detergent tablet with a perfume carrier in a manner so that the perfume carrier would adhere to the tablet and remain so during packaging, transport, storage and handling prior to eventual use.
