Abstract

The invention relates to a silicone-free skin protection composition, in particular a composition to protect against cold, containing the components a.) at least one oil with a pour point in accordance with DIN ISO 30 16 of ≦−10° C., b.) at least one polyol c.) at least one emulsifier d.) optionally at least one wax, where the viscosity difference in the temperature interval from +4° C. to +50° C. of highest and lowest viscosity of the skin protection composition has a value in the range from 0 to ≦20 000 mPas.

Claims (13)

1. A silicone-free composition that consists essentially of:

(a) 10 to 50 wt. % of at least one oil with a pour point of ≦−10° C. in accordance with DIN ISO 30 16,

(b) 15 to 40 wt. % of at least one polyol having 2 to 15 carbon atoms and at least two hydroxyl groups,

(c) 1 to 10 wt. % of at least one emulsifier, and

(d) up to 2 wt. % of at least one wax;

wherein said silicone-free composition is stable and has a viscosity of at most 600 Pas within a temperature range between 1° C. and −30° C. as determined by a constant velocity gradient of d(γ)/dt=10 s −1 .

2. A silicone-free composition that consists essentially of:

(a) 10 to 50 wt. % of at least one oil with a pour point of ≦−10° C. in accordance with DIN ISO 30 16,

(b) 15 to 40 wt. % of at least one polyol having 2 to 15 carbon atoms and at least two hydroxyl groups,

(c) 1 to 10 wt. % of at least one emulsifier, and

(d) up to 2 wt. % of at least one wax; and

(e) water;

wherein said silicone-free composition is stable and has a viscosity of at most 600 Pas within a temperature range between 1° C. and −30° C. as determined by a constant velocity gradient of d(γ)/dt=10 s −1 .
