AMPHOLYTIC TER-POLYMERS FOR USE IN PERSONAL CARE COMPOSITIONS

Novel ampholytic ter-polymers comprising at least an ethylenically unsaturated cationic monomer, a monomer containing a carboxylic acid or sulfonic acid group and diallyamine or derivative are claimed. Further, the ter-polymers may be used in personal care or personal washing compositions optionally in the presence of conditioning agents such as silicone, fatty amines, fatty amine oxides and fatty quaternaries and/or various benefit agents. The ter-polymer compositions are especially useful in the treatment of keratin-containing substrates. Keratin substrates include, but are not limited to, animal and human hair, skin and nails.

DENTAL ORAL COMPOSITION

A dental composition for oral use, containing a phosphorylated saccharide (a), a polyphosphoric acid and/or a salt thereof (b), and a cationic bactericidal agent (c), wherein a ratio of a total amount of the phosphorylated saccharide (a) and the polyphosphoric acid and/or a salt thereof (b) contained to an amount of the cationic bactericidal agent (c) contained, i.e. {(a)+(b)}/(c), is from 0.05 to 20 in a weight ratio. The dental composition for oral use of the present invention can be suitably used for an oral cavity cleaning agent, including dentifrice agents such as a paste dentifrice agent, a powder dentifrice agent, and a liquid dentifrice agent, a mouse-wash agent, a troche, a tablet, a cream, an ointment, a bonding agent, a mouth spray, a coating agent to tooth surface or a dental prosthetic, a hypersensitive inhibitor, a therapeutic agent for periodontal diseases, that is applied to a periodontal pocket, wet tissue for oral cavity care, an oral refreshing agent, chewing gum, or a gargling agent, or the like.

Multicomponent Diffusion of Distearyldimethylammonium Polyelectrolyte Solutions in the Presence of Salt: Coupled Transport of Sodium Chloride

A sensitive conductance method has been used to determine binary and ternary diffusion coefficients of distearyldimethylammonium chloride, bromide, and hydroxide (DSDMACl, DSDMABr, and DSDMAOH) in aqueous solutions in the absence and presence of salt.Experiments were conducted above and below the critical micelle concentration (CMC) at 25 deg C, and the concentration of salt, when present, was 0.015 M NaX (X = Cl, OH, Br).The experiments reveal that diffusion of DSDMA chloride, bromide, and especially hydroxide induces concurrent flow of NaCl, NaBr, and NaOH, respectively.Also diffusion of DSDMAX in the presence of NaCl drives countertransport of DSDMACl or DSDMAOH.At pH 7.5 and an ionic strength of 0.015 M, each mole of diffusing DSDMACl (Nagg = 72, α = 0.15), cotransports 9.0 mol of NaCl.However, coupled flow of NaCl decreases as the solution pH approaches 5.2 and is almost zero at pH 4.5.The corresponding value for diffusing DSDMAOH at pH 7.5 is about 120 mol of NaCl.At pH 6.5 only 10 mol of NaCl are cotransported, and the value is almost zero at pH 5.5.However, at pH 4.5, diffusing DSDMAOH generates a counterflow of NaCl due to bound protons and a release of H2O (DSDMAOH + H(1+) DSDMA(1+) + H2O), yielding a net positive charge; hence, the D21 value is negative.The cross-diffusion coefficient D21 of diffusing DSDMACl in the presence of 0.015 M (0.095-0.009) NaOH and 0.015 M NaCl yields a flux density of NaOH and NaCl, which is generated by the DSDMAX (X = Cl + OH) gradient.A similar cross-diffusion coefficient, D21, is revealed when DSDMAOH, is used, instead of DSDMACl, in the presence of 0.015 M NaCl through induced coupled transport of salt.The coupled transport of NaCl or of NaCl and NaOH is primarily driven by the diffusion-induced electric field along the DSDMAOH and DSDMACl concentration gradients.For the DSDMAOH system, the direction and magnitude of the coupled flow of either NaCl or NaOH can be explained through the ionic mobility of DSDMA(1+) and OH(1-), in addition to the charge and degree of dissociation (Nagg = 6400, α = 0.33-0.35) at 25 deg C.The tracer and mutual diffusion coefficients for the DSDMAX system were compared with those from light-scattering measurements of polyelectrolyte solutions of DSDMAX.
