Mystery Solved! Why Do Most Dish Soap Dispensers Prefer PP Material?
Why are dish soap dispensers made of PP material more often than not? Is there no "fancier" material to choose from? Actually, PP (Polypropylene) become the "mainstream choice" for dish soap dispensers because it precisely matches the usage scenarios of the dispenser, with every characteristic hitting the "must-have" points!
First and foremost, food contact safety is the bottom line. As a common pump dispenser, the dish soap dispenser comes into direct contact with cleaning supplies for tableware and even come into contact with tableware or hands indirectly when pressing. PP material is recognized globally as a "food-contact grade plastic".
It has no odor and does not harmful substances. Even if it comes into long-term contact with surfactants, fragrances, and other ingredients in dish soap, it will not undergo chemical migration, eliminating the of "secondary pollution of cleaning supplies" at the source. This is a safety standard that ordinary plastics (such as PVC, PS) cannot achieve.
Second, the ability resist chemical corrosion is highly adaptable. Dish soap is an alkaline cleaning agent, and some also contain degreasing ingredients. Inferior plastics will crack, discolor and dissolve when exposed for a long time, leading to leakage and failure of the dispenser. Lotion bottle manufacturers often choose PP material first when producing various liquid dispensing containers, because of its extremely strong chemical stability.
For dish soap dispensers, PP can not only resist weak alkalis and weak acids but also withstand various additives in dish soap. Even daily use, the dispenser will not be "corroded and aged", which is also the core reason why it can achieve "thousands of press-ins are still".
Third, its physical properties perfectly match the needs of the dispenser. The hand soap dispenser pump and the dish soap dispenser have similar usage scenarios and require frequent pressing, so the physical properties of the material are highly consistent. PP material has both "rigidity" and "flexibility".
It is not easy to deform under temperature and will not become brittle and crack in a low-temperature environment. At the same time, it has a small density and light weight, making it feel light and comfortable made into a dispenser. It is not laborious to press with one hand and will not be as heavy as a metal dispenser, which can also avoid rust problems.
Additionally, from a supply chain perspective, plastic packaging suppliers are more willing to promote PP material dispensers. Because PP material is easy to process and can easily form the precise structure for the dispenser, and the quality is highly stable during production, it can meet the delivery needs of large orders and reduce the risk of after-sales due to material issues.
Finally, its cost-performance ratio makes it more popular. In the field of product plastic packaging, the balance between cost and quality is always key. Compared with food- stainless steel, PETG, and other materials, PP material has a lower production cost, which means consumers can buy a good dish soap dispenser at an affordable price, forming a quality cost-performance" win-win situation.
So it's not that PP material is "not fancy enough", but that it happens to be the "best solution for dish soap dispensers - safe, durable, easy to use, and not expensive. Such a material is no wonder it has become the industry's first choice.
