The S257WH is a white PP plastic 24-410 ribbed skirt semi-technical fine mist fingertip sprayer with 8.75 inch dip tube. The fine mist finger tip sprayer has a number of parts: the dip tube, cap, spring-loaded pump, and the clear overcap. The sprayer is fitted to a matching container with the dip tube at the base of the bottle. When the pump is depressed, product is discharged in a regular mist pattern. This sprayer is compatible with oil-based formulas. Polypropylene (PP) is marked with the resin identification code of 5. PP is less flexible than LDPE, somewhat stiffer than other plastics, reasonably economical, and can be translucent, opaque, or of any color. PP has very good resistance to fatigue, and has an extremely high melting point (320 degrees Fahrenheit or 160 degrees Celsius). This closure fits a container with a 20-410 neck finish.
