[0144] Dual compartment pouches manufactured using a 0.7 g 76 δm thick water soluble film (M8779, MonoSol, Merrillville IN, USA) were thermoformed to produce dual compartment pouches measuring 44 mm by 44 mm. The pouches were filled with 18 mL (19.0 g) of Product A (Table 1 ) in the first compartment and 3.0 mL (1.6 g) of Product B or C (Table 1 ) in the second compartment.

[0145] Detergent compositions A, B and C were prepared as described below. All amounts are by weight percent of the composition. B is a comparative example and C is an example of the present invention.

[0151] Fifty sachets were delivered into plastic buckets (moisture vapor transmission rate at 20°C about 2.5 g / day / m 2 / %RH) and stored at 35°C / 80%RH (relative humidity) for 8 weeks. The sachets were inspected visually for evidence of product B or C migration into product A after 3 or 8 weeks. Table 2 shows the percent...

Abstract

The present application also relates to a water soluble pouch comprising at least one compartment, the pouch comprising a water soluble film encapsulating a composition, said composition comprising a negatively charged hueing dye and a solvent system comprising a primary solvent having a Hansen solubility (δ) of less than 29.

Description

technical field [0001] This application is concerned with exudation and migration of hueing dyes through water soluble films. Background technique [0002] Water soluble combination dose sachet products have become popular in recent years. Such sachets comprise a water soluble film envelope which surrounds and encapsulates the detergent composition. In the aforementioned patent applications, applicants describe that a preferred component of detergent compositions encapsulated therein are hueing dyes. Shading dyes are coloring compounds that adhere or simply deposit onto the surface of the fabric, giving it color. Hue dyes can impart a variety of colors, however, when used in laundry, they are usually chosen so as to impart blue or purple. Adding blue or purple hues to fabrics enhances the whiteness appearance of fabrics, so they are often also called brighteners. [0003] The applicants have also focused on making multi-compartment pouches in which one compartment contai...
