Polymer Emulsion Chemicals

Potassium persulfate is the inorganic compound with the formula K₂S₂O₈. Also known as potassium peroxydisulfate or KPS, it is a white solid that is sparingly soluble in cold water, but dissolves better in warm water. This salt is a powerful oxidant, commonly used to initiate polymerizations.

his salt is used to initiate polymerization of various alkenes leading to commercially important polymers such as styrene-butadiene rubber and polytetrafluoroethylene and related materials. In solution, the dianion dissociates to give radicals:^[3]

[O₃SO-OSO₃]²⁻ ??? 2 [SO₄]^•−

It is used in organic chemistry as an oxidizing agent,^[4] for instance in the Elbs persulfate oxidation of phenols and the Boyland–Sims oxidation of anilines.

As a strong yet stable bleaching agent it also finds use in various hair bleaches and lighteners. Such brief and non-continuous use is normally hazard free, however prolonged contact can cause skin irritation.^[5] It has been used as an improving agent for flour with the E number E922, although it is no longer approved for this use within the EU.

Nonionic. Nonionic surfactants have covalently bonded oxygen-containing hydrophilic groups, which are bonded to hydrophobic parent structures. ... Nonionic surfactants are less sensitive to water hardness than anionic surfactants, and they foam less strongly.
A wetting agent facilitates the uptake of water during initial wetting and optimises the movement of water in the substrate which improves the re-wetting of over-dry plants. This is due to the wetting agent's ability in lowering the surface tension of water which allows it to spread more easily and evenly in the peat
