Abstract

Oil-in-water emulsions comprised of: (a) a polyol poly-12-hydroxystearate polyester; (b) an alkyl polyglycoside; (c) an oil; and (d) from 5 to 30% by weight water. When used as paper additives, the emulsions significantly improve the softness and feel of the paper products.

Claims (8)

1. An oil-in-water emulsion comprising: (a) from 2-20% by weight of a polyol poly-12-hydroxystearate; (b) from 1-15% by weight of an alkyl polyglycoside; (c) from 20-75% by weight of an oil which is liquid at 20° C.; and (d) from 5 to not more than 30% by weight water, wherein the viscosity of the emulsion is from 100 to 10,000 mPa.s at 23° C.

2. The emulsion of claim 1 wherein the ratio by weight of polyol poly-12-hydroxystearate to the alkyl polyglycoside is from 0.2 to 2.0.

3. The emulsion of claim 1 wherein the oil is selected from the group of glycerides, dialkyl(ene) carbonates and mixtures thereof.

4. The emulsion of claim 1 further comprising a humectant.

5. The emulsion of claim 1 further comprising an irritation-soothing agent.

6. The emulsion of claim 1 further comprising a thickener.

7. The emulsion of claim 1 further comprising an emulsifier selected from the group of a nonionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, a cationic and an anionic surfactant.

8. An oil-in-water emulsion comprising: (a) from 2 to 15% by weight of polyglycerol poly-12-hydroxystearate; (b) from 30 to 70% by weight of at least one thinly liquid oil component which is liquid at 20° C.; (c) from 1 to 15% by weight alkyl oligoglucoside; (d) from 2 to 10% by weight of at least one humectant and (e) from 10 to not more than 25% by weight of water, wherein the viscosity of the emulsion is from 100 to 10,000 mPa·s at 23° C.
