Refills and Replacements

Refill packs have taken root in Japan. By having consumers refill product contents and continuously use the same plastic packaging for shampoo and liquid detergent, Kao helps reduce the use of natural resources as well as the amount of waste.

Kao released its first refill packs in 1991 and has continued releasing more refill products. As of December 2017, Kao offers 289 refill products. To make it easier for consumers to refill plastic bottles, Kao has modified refill products in accordance with the bottle sizes and the viscosity of contents.

Special Measures on Refill Packs

As of December, 2017

Smart Holder

Special features Procedure and example
・Exclusive holder for Raku-raku Eco Pack Refill that does not need refill work to a bottle.

・It can be installed in Eco-pack in about 10 seconds.

・It is possible to use it without waste by the end with a pump of our own development.

Raku-raku Eco Pack

Special features Design and example
Raku-raku Eco Pack Refill for refilling high viscosity liquids, such as shampoo and body cleansers.

・The refill packaging cap fits neatly inside the mouth of the regular bottle upside down, without leakage.

・Because film is thinner and softer than existing products, this makes it easier to refill quickly without wasting or spilling.

Pour type

Special features Design and example
・ Refill pack for large volume of medium viscosity liquids, such as liquid laundry detergent

・ Spout has concave/convex embossing to ensure smooth flow of liquid along press line.

"Itself can be replaced" type

Special features Procedure and example

Meanwhile, we do not recommend that consumers refill certain products, from the viewpoint of the product's nature and safety. For such products, we make certain parts of a container to be reusable, such as spray nozzles.

The ratio of refill products available from Kao rapidly increased after 1997 and is a little over 80%. Refill usage rate for Humming (Concentrated Type), for example, is 98%. Compared to if all our refill and replacement products sold in fiscal 2015 were in plastic bottles, providing refill products means that our use of plastics has dropped by slightly more than 70,000 tons.
