A method and apparatus is disclosed for producing a fragrance-containing solid particle, capable of controllably releasing the fragrance to the environment in which the particle is contained for incorporation into laundry detergents, fabric softener compositions and drier-added fabric softener articles.

The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, fabric care products, such as fabric softeners, laundry detergents, rinse added products, and other fabric care products, to enhance fragrance performance. The controlled delivery system of the present invention is a solid, substantially spherical particle comprising hydrophobic cationic charge enhancing agents in conjunction with cationic fabric softening agents that assist in adhering the particles onto fabric. The particles can also include a fragrance. The particle can have an average particle diameter of from about 1 micron to about 500 microns. The controlled delivery system of the present invention can be utilized to deliver a broad range of fragrance ingredients onto fabric and prolong fragrance release from the dry laundered fabric over an extended period of time, or yield a high impact fragrance “burst” upon ironing the fabric. The invention also pertains to fabric care products comprising the controlled release system of the present invention.

The present invention relates to a block polymeric material. Typically the block polymer comprises units capable of having an average cationic charge density of about 15 or less, preferably 5 or less, more preferably from about 0.05 to about 5, even more preferably from about 0.05 to about 2.77, even more preferably from about 0.1 to about 2.75, most preferably from about 0.75 to about 2.25 units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for personal care products such as soaps and shampoos. The compositions have increased effectiveness for preventing re-deposition of grease during hand and body washing. The polymers are also effective as a soil release agent in fabric cleaning compositions. The polymeric material is also effective in oil well treating foam, fire-fighting foam, hard surface cleaning foam, shaving cream, post-foaming shaving gel, dephiliatories and as a coagulant/retention aid for titanium dioxide in paper making.

An automatic laundry washing machine that is suitable for use in living units having no area set aside for laundry facilities is achieved by replacing the heavy bulky parts of the currently popular automatic washing machine design with a light flexible bag. A large portion of the volume of any washing machine is the vessel for containing the laundry solution and articles to be washed. That vessel is a flexible bag made of modern durable material so as to be collapsible both while in use and for storage. The method of use includes the complete process of washing, rinsing, and extracting excess water in an automatic cycle analogous to standard automatic washing machines popular today. The vessel containing the items being laundered is a waterproof laundry bag with automatic washing apparatus attached. Items are automatically washed in that bag. The automatic process includes cycles of filling, washing, rinsing and extracting such that the clothes are ready for a drying process such as hanging out to dry or putting into a tumble dryer. The agitating of the washing and rinsing cycles is accomplished without the familiar bulky agitator thereby reducing the volume requirements and the traditional wear and tear on the garments. By eliminating the bulky agitator and the spin water extraction method, the heavy transmission is also eliminated. The water extraction cycle is done in a much less violent way than the conventional spin cycle by allowing atmospheric pressure to collapse the washing vessel and press the water from the articles as the water and air are pumped from the vessel in the draining portion of the cycle. The cleaning ability of the water is enhanced by built in ionic processing of the water thereby reducing the required amount of laundry detergent. The agitating in the non-electrically conductive vessel generates static electric charges in the process and ions thus produced further enhance the cleaning ability of the water. Cavitation produced in a multi-frequency washing action further enhances the washing ability of the water. The washing machine is light, compact and collapsible and is as portable as a piece of luggage. The set up procedure is simple and no assembly is required beyond attaching a quick connect fastener to a water faucet and plugging in a power cord. The washing machine is light and takes little storage space. It can be put in a small closet or on a shelf when not in use. The minimum capacity of the washing machine is a single garment. The normal capacity of the washing machine is comparable to that of a standard household washing machine.

A non-intrusive device for automatically dosing at least one liquid laundry care composition to an automatic laundry washing machine. The device employs a Venturi tube mechanism or a pump to dose the laundry detergent care composition. The dosing is controlled by a machine-generic algorithm capable of determining the actual cycle at any duration of wash for various cycle designs from various washing machines, without the input of precise cycle design; and dose the correct products correctly and is capable of distinguishing between major water addition and a water pulse.

A method of conditioning articles using the inventive compositions is also disclosed.

This invention relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component and at least one polymeric component.

The ability of aqueous laundry compositions to remove organic hydrophobic soils, such as oily, greasy or particulate soils, from a laundry item is substantially improved by pre-spotting or pre-treating such a soiled item with a treatment composition having a surfactant comprising a unique hydrophillic ethoxylate surfactant with less than two moles of ethylene oxide or a or blend of at least two surfactant compositions with a blended HLB value of about 7-12. The blend of surfactants with this HLB value penetrates soils and renders the soil more easily removed from the item using aqueous laundry detergent. The treatment composition can be used in a liquid or solid form and can be applied to individual laundry items in the form of a solid stick or liquid spray prior to introduction to the laundry machine. Laundry items can also be contacted in the laundry machine with the pre-spot or pre-treatment composition in the form of an aqueous presoak, preflush, prewash, or other step prior to the cleaning step. A preferred laundry machine comprises an institutional tunnel washer.
