Recently, the COVID-19 epidemic has raged, and customers in many countries have purchased plastic bottles for disinfecting alcohol. So, can plastic bottles contain alcohol-free or alcohol-containing cosmetics? Please take a look at our analysis.

The main components of plastic bottles are made by mixing synthetic resins and additives in a specific ratio. Common ones are PET, PP, PVC, PC, PE, PS, etc. Although most of them will not chemically react with alcohol, they are not excluded. Some plastics or additives in them will be corroded by alcohol. The wine used for drinking must be careful not to use plastic bottles casually. At present, only food-grade plastics, such as PET, can be filled with alcohol.


PET, the English name is Polythylene terephthalate, referred to as PET or PETP (hereinafter referred to as PET), commonly known as polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol, collectively referred to as thermoplastic polyester or saturated polyester together with PBT. PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good friction resistance and dimensional stability, low abrasion and high hardness, have the greatest toughness among thermoplastics; good electrical insulation performance, less affected by temperature, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents.


The 75% alcohol in plastic packaging bottles must be medical food-grade plastic packaging. It needs to undergo strict testing. The country has a strict quality control center, which will not pollute the alcohol or cause dissolution. , Customers can rest assured to use our pet plastic bottles, which will not have any adverse effects on alcohol-based cosmetics/disinfectants.
