Paintballs, also simply called "paint", are spherical gelatin capsules containing primarily polyethylene glycol, other non-toxic and water-soluble substances, and dye. Paintballs are made of materials found in food items, and are edible but taste disagreeable as they tend to dry up the mouth. [ 4 ]
The polymer is a liquid at room temperature. Solubility in water decreases rapidly with increasing molar mass. Secondary hydroxyl groups in PPG are less reactive than primary hydroxyl groups in polyethylene glycol. PPG is less toxic than PEG, so biotechnologicals are now mainly produced with PPG. [4] [5] [6]
Non-contact - While paintball does involve tagging players with paintball projectiles, this is generally considered the sole point of physical contact between members of opposing teams. Players are generally prohibited from physically contacting other players, such as colliding with them, physically restraining them, and especially using fists ...
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry.They came to prominence in 2015, when the UN defined a new sustainability-focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

Polar liquids have a tendency to be more viscous than nonpolar liquids. [citation needed] For example, nonpolar hexane is much less viscous than polar water. However, molecule size is a much stronger factor on viscosity than polarity, where compounds with larger molecules are more viscous than compounds with smaller molecules.
A multiphasic liquid is a mixture consisting of more than two immiscible liquid phases. Biphasic mixtures consisting of two immiscible phases are very common and usually consist of an organic solvent and an aqueous phase ("oil and water"). Multiphasic liquids can be used for selective liquid–liquid extractions or for decorative purposes, e.g ...

The polar components would be attracted to the polar silanol (Si-OH) groups on the surface of the silica gel, and the nonpolar components would travel further with the hexanes. [1] Further, dyes in glow sticks can also be extracted using liquid carbon dioxide (CO 2) as an environmentally friendly or green solvent.
