Foam bottles are made from PET plastic and are odorless and reusable. Tawny PET foam bottles can be supplied with white foam pumps of different sizes. Tawny-colored plastic non-aerosol foam pumps can produce high quality foam without using gaseous propellants. The use of foam pumps can reduce soap consumption. The unique tight thread of the foam bottle prevents any leakage. Most commercial or even industrial liquid or foam soaps will also work in foam pump bottles, but if over-diluted, they may not work as well. But, most liquid foaming soaps have ingredients such as glycerin or glycolic acid in them, which help make them foam properly. Many commercial cleaning soaps also contain these compounds as ingredients, but often times, they are mixed in with other chemicals in order to create a more effective cleaning agent. Other industrial cleaners such as bleach, peroxide and hydrogen peroxide may also be used as well. However, many commercial cleaning soaps contain additional ingredients such as enzymes that help to speed up the cleaning process and prevent damage to your furniture or carpet. https://www.penghuangbottle.com/gel-nail-polish-bottle/
