received by the International Bureau on 09 November 2020 (09.1 1.2020)

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A package, comprising:

a water-dissolvable substrate forming the exterior of the package;

a pre-measured powdered hair bleach composition in at least one chamber of the package; and

an anhydrous hair bleach developer liquid composition in a second chamber of the package, the second chamber being separated by a barrier from the first chamber.

2. The package of Claim 1, further comprising:

an additive composition configured to enhance a property of the powdered hair bleach.

3. The package of Claim 1,

wherein the water-dissolvable substrate includes hydrophilic polymers or a disintegrant.

4. The package of Claim 1,

wherein the water-dissolvable substrate includes a release mechanism triggered by one of at least moisture and friction.

5. The package of Claim 1,

wherein the water-dissolvable substrate interacts with an external agent to enhance a property of one or both compositions.

6. The package of Claim 1,

wherein the water-dissolvable substrate is made from woven or non-woven fibers, wherein the fibers are impregnated with a hair bleach developer composition.

7. The package of Claim 1,

wherein the water-dissolvable substrate is consumed in a reaction with water.

8. The package of Claim 1, comprising: 69 a first and second water-dissolvable substrate forming the exterior of the package; and

the first chamber is formed from the first water-dissolvable substrate; and the second chamber is formed from the second water-dissolvable substrate, wherein the first and second water-dissolvable substrates have different rates of dissolution.

9. The package of anyone of Claims 1-8, comprising synthetic or plant-derived dissolvable substrates and compositions.

10. A container, comprising:

a plurality of water-soluble packages of Claim 1.
