Polyoxyethylene Sorbitan Tristearate

The stability characteristics of two different antiperspirant lotion systems were compared. Sample 1 represented an aqueous emulsion containing an aluminum salt. The internal phase consisted of stearyl alcohol and ethylene oxide reaction products, polyoxyethylene sorbitan monostearate and polyoxyethylene sorbitan tristearate. Methylcellulose was used as a stabilizer and bodying agent. Sample 2 represented a dispersion of magnesium aluminum silicate in an aqueous system containing aluminum ions. Because of its com-... [Pg.88]

Essentially, Tri-Act corrosion inhibitors are based on various combinations and ratios of different sorbitan fatty acid esters (e.g., sorbitan tristearate) and polyoxyethylene sorbitan fatty acid esters (e.g., POE... [Pg.544]

The optimum HLB number for forming an emulsion depends to some extent on the nature of the particular system. Suppose that 20 per cent sorbitan tristearate (HLB 2.1) plus 80 per cent polyoxyethylene sorbitan monostearate (HLB 14.9) is the optimum composition of a mixture of these emulsifiers for preparing a particular O/W emulsion. The HLB of the mixture is, therefore, (0.2 x 2.1) + (0.8 x 14.9) — 12.3. The theory is that an HLB of 12.3 should be optimum for the... [Pg.267]

An o/w emulsion is made from 20% sorbitan tristearate with an HLB value of 2.1 and 80% polyoxyethylene sorbitan monostearate with an HLB value of 14.9. [Pg.279]

Polysorbates are surfactants that are pegylated derivatives of sorbitan monoesters (i.e., monolaurate, monopalmitate, monostearate, monooleate, or monoisostearate) or sorbitan triesters (i.e., tristearate or trioleate) and are available in many grades. Poly-sorbate 80, also known as Tween 80, is a mixture of polyoxyethylene 20 sorbitan monooleates and is a yellow viscous liquid at room temperature. Sorbitan monooleate, also known as Span 80, is a yellow viscous... [Pg.3346]
