Emulsifying agents cetyl alcohol

HLB values decrease as the solubility of the surface-active agent decreases in water. Solubility of cetyl alcohol in water (at 25°C) is less than a milligram per liter. It is thus obvious that, in any emulsion, cetyl alcohol will be present mainly in the oil phase, while SDS will be mainly found in the water phase. Empirical HLB values are found to have significant use in emulsion technology applications. It was shown that HLB is related, in general, to the distribution coefficient, KD, of the emulsifier in the oil and water phases ... [Pg.177]

Cetyl alcohol is also used for its water absorption properties in water-in-oil emulsions. For example, a mixture of petrolatum and cetyl alcohol (19 1) will absorb 40-50% of its weight of water. Cetyl alcohol acts as a weak emulsifier of the water-in-oil type, thus allowing a reduction of the quantity of other emulsifying agents used in a formulation. Cetyl alcohol has also been reported to increase the consistency of water-in-oil emulsions. [Pg.155]

In oil-in-water emulsions, cetyl alcohol is reported to improve stability by combining with the water-soluble emulsifying agent. The combined mixed emulsifier produces a close packed, monomolecular barrier at the oil-water interface which forms a mechanical barrier against droplet coalescence. [Pg.155]

In semisolid emulsions, excess cetyl alcohol combines with the aqueous emulsifier solution to form a viscoelastic continuous phase that imparts semisolid properties to the emulsion and also prevents droplet coalescence. Therefore, cetyl alcohol is sometimes referred to as a consistency improver or a bodying agent , although it may be necessary to mix cetyl alcohol with a hydrophilic emulsifier to impart this property. [Pg.155]

The oil phase preferably includes mineral oil, petrolatum, cetyl alcohol, or stearyl alcohol. Emulsifiers such as polysorbate 80, sorbitan monostearate, or others known in the art may be used. Buffering agents, antioxidants, and chelating agents may be added to improve the characteristics of the formulation. [Pg.130]

Fatty alcohols such as cetostearyl alcohol and wool alcohols are lipophilic chains with a hydroxyl group at the end. Because of the combination of the lipophilic chain and the hydrophilic hydroxyl group these stmctures reduce the surface tension (see Sect. 18.4.3). Cetostearyl alcohol is a mixture of cetyl alcohol and stearyl alcohol. It is a weak water-in-oU emulsifying agent and it is a component of self-emulsifying waxes. [Pg.241]
