Methyl paraben is mainly used as a bactericidal and preservative in organic synthesis, food, cosmetics and medicine, and is also used as a feed preservative
Methylparaben is a widely used preservative in personal care products like moisturizers, hair care, and shaving products to prevent bacterial and mold growth.
It is used as a food preservative to inhibit spoilage, identified by the E number E218
It is a non-toxic and safe ingredient that is good for the skin when used in small quantities. It is also non-sensitizing but can be mildly irritating for sensitive skin. A patch test is, therefore, recommended. It is also safe for the environment and may or may not be considered vegan - depending upon its source.
While generally non-irritating for normal skin, some individuals may experience allergic reactions to parabens.
keep the product dry
relative humidity < 50%
protect product against influences of weather and contamination
Its technical application is the only one that offers packaging in different sizes. It can be packaged in various specifications: 25kg drums, 1000kg IBC drums.
