Preparation containing diol

Abstract

The invention is a cosmetic or dermatological formulation comprising a) at least one polyol in a concentration of from 0.1 to 20% by weight, based on the total weight of the formulation, and b) at least one diol selected from the group consisting of 2-methyl-1,3-propanediol, pentanediol, and hexanediol, in a concentration of from 0.1 to 25% by weight, based on the total weight of the formulation. The invention also includes formulations further comprising at least one antioxidant, and formulations further comprising at least one UV filter. The invention also includes a method of moisturizing skin comprising applying the formulation to the skin. The invention further includes a method for reducing the tacky sensation, a method for reducing the viscosity, and a method for increasing the stability of a polyol-containing formulation comprising adding a diol selected from the group consisting of 2-methyl-1,3-propanediol, pentanediol, and hexanediol.

Description

FIELD OF THE INVENTION The present invention relates to cosmetic or dermatological formulations comprising one or more polyols in a concentration of 0.1 to 20% by weight, one or more diols from the group consisting of 2-methyl-1,3-propanediol, pentanediol, hexanediol in a concentration of 0.1 to 25% by weight, in each case based on the total weight of the formulation, and the use thereof. BACKGROUND OF THE INVENTION The skin is the largest organ of humans. Its many functions (for example for regulation of heat and as a sense organ) include the barrier function, which prevents the skin (and therefore in the end the entire organism) from drying out, certainly the most important. At the same time, the skin acts as a protective device against penetration and uptake of substances from the outside. This barrier function is effected through the epidermis, which as the outermost layer forms the actual protective covering against the environment. With about one tenth of the total thickness...

AI Technical Summary

Benefits of technology

It was therefore the object of the present invention to eliminate this disadvantage of the prior art and to develop inexpensive cosmetic or dermatological formulations with significantly improved sensory properties. In particular, the formulations should not feel tacky. The content of silicone oils and other lipids which reduce the tackiness should be reduced.

The formulations according to the invention are distinguished by a high heat stability and low viscosity at low temperatures. Furthermore, they have excellent sensory properties, such as a low feeling of tackiness on the skin.

Problems solved by technology

Since the development of cosmetics or dermatological agents is quite involved and expensive, attempts are increasingly being made to develop recipes which can be employed globally under the most diverse climate conditions.

However, the heat stability of these highly complex metastable mixtures is relatively limited.

At low temperatures of below 5° C. their viscosity increases so severely that the formulations can scarcely still be used or processed.
