[0244] Example 2: Different OCF Structures of Solid Sheets Produced by Different Heating / Drying Apparatus

[0245] Wet premixes were prepared with the following surfactant / polymer compositions as described in Table 1 below.

[0246] Table 1

[0247]

[0248] The viscosity of the wet premix composition as described in Table 1 was about 14309.8 cps. After aeration, the average density of such an aerated wet premix is ​​about 0.225 g / cm 3 .

[0249] A flexible porous dissolvable solid sheet A was prepared from the above wet premix described in Table 1 by using a continuous aerator (Aeros) and a rotary drum dryer with the following settings and conditions as described in Table 2 below:

Abstract

The invention relates to a flexible and dissolvable solid sheet article. Provided herein is a flexible and dissolvable solid sheet article, the solid sheet article includes PVA polymers or copolymershaving a weight average molecular weight of from 50,000 Daltons to 400,000 Daltons, and primary surfactants selected from the group consisting of C6-C20 linear alkylbenzene sulfonate (LAS), alkoxylated tridecyl polyoxyethylene ether sodium sulfate (STS), and combinations thereof.

Description

technical field [0001] The present invention relates to a flexible and dissolvable solid article comprising polyvinyl alcohol and one or more surfactants. Background technique [0002] Flexible and dissolvable cleaning sheets comprising one or more surfactants and other active ingredients in a water-soluble polymer carrier or matrix are well known. Such sheets are particularly useful for delivering surfactants and other active ingredients when dissolved in water. Such sheets have better structural integrity, are more concentrated and are easier to store, transport / transport, carry and handle than traditional granular or liquid detergents in the same product category. Compared to solid tablet detergents in the same product category, such sheets are more flexible and less brittle, offering better sensory appeal to consumers. [0003] A challenge for manufacturers of such flexible and dissolvable detergent sheets is that there are only limited Surfactants are suitable for in...
