Abstract

Aqueous cosmetic preparation (I) comprises 1,2-hexanediol.

Description

The The present invention relates to face waters containing 1,2-hexanediol.

Of the Wish, nice and looking attractive, is inherently rooted in man. Even if the ideal of beauty has undergone changes over time, so is the pursuit of a flawless appearance always been the goal of the people. A substantial portion of one beautiful and attractive looks while the condition and appearance of the skin.

In order to the skin can fulfill its biological functions to the full extent, it requires regular cleaning and care. The cleaning of the skin serves the removal of Dirt, sweat and leftovers Dead skin particles that provide an ideal breeding ground for pathogens and parasites of all kinds. Skin care products are usually moisturizing and refatting of the skin. Often are added to them active ingredients that regenerate the skin and for example, their premature aging (eg the emergence of Pucker, To prevent and reduce wrinkles).

Face waters are usually largely free of fats and oils. Usually done already the incorporation of perfume oils by addition of solubilizers.

One often problem of such preparations is their tendency flocculation, so the products stored some time - 2 to 4 months become. Such flocculations are unpleasant and especially transparent Preparations very undesirable. Therefore, many face waters colored or opaque to the poor visual impression by concealing the flocculations.

It was therefore the object of the present invention, perfume-containing Toners to find that are transparent and not cause flocculation longer Tilt storage.

Surprised solved The object is achieved by the addition of 1,2-hexanediol to a cosmetic aqueous Preparation, the invention thus consists in a cosmetic aqueous Preparation containing 1,2-hexanediol. The invention also includes the use of 1,2-hexanediol as dispersing agent for low lipophilic proportions of a predominantly aqueous cosmetic preparation.

Of the Use of 1,2-alkanediols in cosmetic preparations is the Skilled in the art, but the prior art could not point the way to the present invention.

The WO 95/01151 discloses the use of alkanediols having 5-7 carbon atoms in cosmetic preparations. Preparations according to the invention with 1,2-hexanediol however, are not explicitly disclosed. Likewise, there are no embodiments with 1,2-hexanediol and / or with the emulsifiers according to the invention.

The DE 103 41 179 discloses deodorant compositions comprising a combination of alkane-1,2-diols, including 1,2-octanediol and α- and / or β-hydroxy acids. However, preparations according to the invention with 1,2-hexanediol are not disclosed.

EP 1078638 discloses sunscreen formulations with high concentrations of 1,2-hexanediol. That it would be advantageous to use small amounts of 1,2-hexanediol in largely aqueous preparations, however, can not be found in the document.

It is preferred if a preparation or use according to the invention by a content of 1,2-hexanediol in the preparation 0.3 to 3 wt .-%, particularly preferably from 0.5 to 1.5 wt .-% based on the total weight the preparation is characterized. It is further preferred if the preparation contains one or more compounds selected from the group phenoxyethanol, methylparaben, propylparaben. It is preferred if the content of phenoxyethanol, methylparaben, propylparaben is from 0.1 to 1.0% by weight, particularly preferably from 0.2 to 0.5% by weight, based on the total weight of the preparation. It is further preferred if the viscosity, measured with the Haake Viscotester VT2, is 100 to 2000 mPas, particularly preferably 100 to 1000 mPas, very particularly preferably 100 to 500 mPas. The Viscosity according to the invention was measured with a Haake Visco-Tester 02 viscometer. This type of viscometer consists of a rotating cylinder and a stationary measuring cup. The device uses the rotational resistance force of the formulation to determine the viscosity of the sample. Speed (rpm) = 62.5. Viscosity after 30 s. determine (measuring temperature = 20 ° C).

Further it is preferred if the water content of the preparation is greater than 84% by weight, particularly preferably greater than 88% by weight, most preferably greater than 89% by weight, very unusual greater than 90% by weight is. Furthermore, it is preferred if the content of lipids without addition of pantheol in the preparation is from 0.2 to 0.5% by weight. Further it is preferred if the content of lipids optionally with Addition of pantheol in the preparation 0.2 to 3 wt .-% is. Further it is preferred if the content of monohydric or polyhydric alcohols with a molecular weight of at most 181 g / mol in the preparation is 6 to 14 wt .-%.

The Preparation can be advantageous according to the invention also as a spray or as a soaking medium for a plaster or cloth are used. Therefore, also plaster and cloths are soaked with the preparation according to the invention, according to the invention.

The Water phase of the preparation according to the invention can be beneficial usual contain cosmetic excipients, such as alcohols, in particular such low C number, preferably ethanol and / or Isopropanol, diols or polyols of low C number and their ethers, preferably propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl or -monobutyl ether, propylene glycol monomethyl, -monoethyl- or monobutyl ether, diethylene glycol monomethyl or monoethyl ether and analogous products, polymers, foam stabilizers, electrolytes, Self, Repellents.

When further care substances can especially niacinamide, panthenol, aloe vera, hamamelis extract, polidocanol, Vitamin E, Vitamin A, Vitamin A derivatives, Vitamin C, Vitamin C derivatives, Coenzyme Q10, creatine, taurine, alphaglycosylrutin and / or in concentrations from 0.1 to 30 wt .-%, based on the total weight of the preparation be used.

The The following examples illustrate the present invention without restricting it. The Information always refers to% by weight, unless otherwise stated be made.
