Abstract

The present invention relates to a stable anhydrous detergent concentrate formulation in solid form.

Description

Anhydrous detergent concentrate and process for making same
Background
Most detergent products are popular as containers with dispensers. They may also be bulk-packed as a filler. Most of these containers are plastic, glass, cardboard lined with plastic as a water barrier. Most of the time these detergents on the market are in the form of dilute liquids or gels. One of the problems is packaging. Disposable plastics are ubiquitous and cause serious environmental damage. Only 9% of virtually all plastics are recycled and packaging generates the largest portion of municipal waste (about 30%). Packaging products is inefficient for businesses and those who purchase them.
The removal of water from detergent formulations removes the need for disposable plastic packaging and the consequent waste, such as packaging waste, product waste and resource waste for transporting water.
Accordingly, there is a need for new stable detergent concentrate formulations to meet consumer demand while also reducing the amount of waste generated in their production and transportation.

The amount of alkaline cleaner in the formulation may range from about 40wt% to about 50wt%, based on the total weight of the formulation. The alkaline detergent may be sodium carbonate, sodium bicarbonate and/or any other alkali metal carbonate.
The amount of surfactant in the formulation may range from about 1% to about 15% by weight, based on the total weight of the formulation. The surfactant may be a natural surfactant or a synthetic surfactant, such anionic, nonionic, amphoteric, zwitterionic or cationic surfactants, such as anionic and nonionic surfactants, also such as surfactants selected from sodium cocoate, ethoxylated alcohols (such as ethoxylated alcohol C (10-12) -C (14-16) with 4 to 8 moles of ethoxylation, e.g., clariant Genapol LA 060 (ethoxylated alcohol C12-C16) w/6 moles ethoxylation, ethoxylated alcohol C8-C10-8 moles EO, etc.), sodium lauryl sulfate and alkylpolyglycosides (such as lauryl glucoside, caprylyl/myristyl glucoside, caprylyl/decyl glucoside).
The amount of enzyme in the formulation may range from about 9wt% to about 25wt%, based on the total weight of the formulation. The enzyme may comprise a protease (e.g., subtilisin), an amylase, a mannanase, a pectate lyase, and a cellulase.
In some embodiments, the amount (e.g., weight) of enzyme present in the formulation is greater than the amount (e.g., weight) of surfactant. It is desirable to have more enzyme in the formulation than surfactant because enzymes are biosynthetic and are very readily biodegradable, while surfactants take longer to biodegrade. Enzymes also target each type of stain better than using only surfactants. By having a high level of enzyme, the overall dose size can be reduced.
The amount of disintegrant in the formulation may range from about 1% to about 10% by weight, based on the total weight of the formulation. The disintegrant may comprise sodium starch glycolate and/or microcrystalline cellulose.

The formulations disclosed herein that include a disintegrant, such as sodium starch glycolate and/or microcrystalline cellulose, are more completely soluble in cold water (40 ° F to 60 ° F) than an otherwise identical formulation that does not contain sodium starch glycolate and/or microcrystalline cellulose.
The amount of glidant in the formulation is less than 1 weight percent based on the total weight of the formulation. For example, it may range from about 0.1 wt% to about 0.7 wt%, based on the total weight of the formulation. The glidant may comprise hydrated silicon dioxide, a medium chain triglyceride having two or three fatty acids with aliphatic tails of 6-12 carbon atoms. Hydrated silica may also act as a desiccant.
The amount of filler in the formulation may range from about 2 to 6 weight percent based on the total weight of the formulation. Exemplary fillers may be selected from glucose, dextrin, starch, inulin, and sodium silicate.
The pH of a formulation dissolved in an appropriate amount of water may range from about 7.0 to about 9.0.
The formulation may also include a fragrance, which may be a natural fragrance (e.g., essential oils) and/or synthetic fragrances and perfumes in the form of oils, crystals, powders, granules, and capsules. The perfume may be selected from aromatic clean basil.
The formulation may also include a dye or colorant which may be any of food, pharmaceutical and cosmetic (FD & C) approved dyes and colorants.
The stable anhydrous detergent formulation may be in the form of a tablet. For example, the tablet may be of any size such that one tablet per load is sufficient to wash the laundry. In some embodiments, the tablet is in the range of about 6.2 g/tablet to 6.8 g/tablet.
When the formulation contains acidic and alkaline detergents, the tablet may have sufficient hardness to avoid foaming during storage and/or the tablet may contain a drying agent such as hydrated silicon dioxide or any other known aid for absorbing moisture.
Process for preparing stable anhydrous detergent tablets
The stable anhydrous detergent tablets may be prepared using any suitable process. Stable anhydrous detergent tablets can be prepared using direct compression or wet granulation processes. For this application, direct compression is most preferred. The term direct compression (or direct compaction) is used to define a process whereby tablets are compressed directly from a mixture of powdered ingredients into a firm mass without the use of a wet granulation process. The powders were homogeneously blended by using a blender (ribbon blender, V blender, paddle blender, drum blender). The powder blender was then loaded into the hopper of a tablet press. The desired weight, compression ton and hardness of the tablet are set as it is compressed and comes out of the tablet press.
Process for using stable anhydrous detergent tablets
In one aspect, the invention comprises a method of using any of the tablets described herein, the method comprising the steps of: (1) Placing the tablet in a container of a washing machine, wherein the container is for storing a detergent; and (2) turning on the power of the washing machine.
The detergent tablet may be stored in any suitable container, such as but not limited to a plastic, glass, aluminium, ceramic or acrylic container. The container may contain a desiccant. The container may be reusable and refilled with new tablets as needed.
