Human oral retention of zinc from mouthwashes containing zinc salts
and its relevance to dental plaque control.
That are the molar ratios of the starting reagents in the working solution: zinc salt
, trisodium citrate, thiourea--0,04 : 0,04 : 0,10 moles respectively with a deposition time of 80 min and a temperature 70[degrees]C.
In this case only the blend containing zinc salts
from both polymers attains a fine dispersion of the minor (Surlyn) phase and demonstrates that viscosity considerations alone are not sufficient to explain the compatibilization mechanism.
of the sulfonated ethylene-propylene-diene terpolymer formed by the sulfonation of the pendent unsaturation in the thermoplastic EPDM followed by neutralization of the resultant EPDM sulfonic acid using the procedure described by Makowski et al (ref 13).
In his scheme, the soluble zinc salt
forms a complex with the accelerator and sulfur.
Table 2 - comparison of zinc salts
Formulation (phr) HNBR (<0.
The abbreviations represent the assay of the pentachlorothiophenol (P) or the corresponding zinc salt
(ZP) as a percentage by weight and the assay of the proprietary booster (FeHe) in parts per hundred thousand.
The reinforcement of HSN with ZnO and MAA has been postulated to be the result of the combined formation of the zinc salt
of methacrylic acid polymer particles which graft onto the HSN elastomer chain.
- 27 ingredients - Safe with non-irritating caveat
It is clear from the above data that strain S2 and YIC are showing very promising results when used alone and when used in combination with Zinc salts
