One of the soluble packaging’s best friends is the soluble ingredient (bestie check!) The latter refers to solid formulations that, once moistened, take their final usable form. Solid formulations offer appreciable benefits in terms of stability, allowing high concentrations of active ingredients, resulting in a better user experience for customers.

Let’s focus on shower gels. The principle is both simple and ingenious: instead of regularly buying traditional bottles, which contain a large amount of water and are packaged in disposable plastic packaging, consumers can now opt for a format of shower gel in solid active ingredient. The latter comes in the form of bars that can be dissolved in water at home to reform the liquid shower gel. Refill, moisten and shake it off! It’s also a moment of entertainment and learning for children, Do It Yourself-wise. Your kids (and the planet) will thank you later.

Forgo, a Swedish cosmetics brand, has developed an effective solution to eliminate plastic: a refillable glass bottle and plastic-free paper refills to make hand soap. Just pour the refill powder into the bottle, add water, and shake (a Mojito, please)! Each refill means no plastic bottle and up to 85% fewer greenhouse gas emission.
