Definitions
- cosmetic products not only serve to look beautiful and attractive, but with their effect they make a decisive contribution to increased self-esteem and the well-being of people. Accordingly, a wide variety of cosmetic products are used for the daily cleaning and care of human skin.
- the present invention relates to a water-containing, transparent gel (hydrogel) which, in addition to water, comprises at least two gel formers.
- the gel according to the invention preferably contains at least one cosmetic active ingredient.
- Hydrogels and their use for administering cosmetic ingredients to the skin or mucosa of a human are known.
- the term "gel” is understood to mean relatively dimensionally stable, easily deformable disperse systems made up of at least two components, which usually consist of a - usually solid - colloidally divided substance made up of long-chain molecular groups (e.g. gelatine, silicic acid, polysaccharides) as a builder and a liquid dispersing agent (e.g. water.
- the colloidally divided substance is often referred to as a thickening agent, gelling agent or gelling agent. It forms a spatial network in the dispersing agent, with individual colloidally present particles more or less firmly connected to one another via electrostatic interaction can be linked.
- Acrylic acid polymers are mainly used as thickeners.
- the existing free carboxy groups of these polymers are by alkalis - such.
- cellulose derivatives or other polysaccharides, such as guar flour or xanthan gum are used as gelling agents. Depending on the type and amount of thickening agent, the consistency of a gel can be adjusted from liquid to firm.
- the dispersing agent surrounding the network is characterized by electrostatic affinity for the thickening agent, ie a predominantly polar (especially: hydrophilic) thickening agent preferably gels a polar dispersing agent (particularly: water), whereas a predominantly non-polar thickener preferentially gels non-polar dispersing agents.
- Hydrogels can consist of almost 100% water (in addition to, for example, approx. 0.2-1.0% of a gelling agent) and can have a solid consistency.
- gels are generally characterized by a semi-solid, often flowable consistency.
- hydrogels from DE2005056497 A1, among others.
- acrylate-based polymers are often used for gel formation.
- Acrylate-based polymers are polymers obtained from homo- or copolymerization with acrylic and/or methacrylic acid. Examples include sodium polyacrylate or acrylate copolymer.
- the subject matter of the present invention is a cosmetic hydrogel comprising a) dehydroxanthan gum and b) xanthan gum and/or carrageenan and c) water.
- Another object of the invention is the use of xanthan gum and/or carrageenan for stabilizing the viscosity of a hydrogel comprising dehydroxanthan gum and water.
- weight percentage ranges are given below for the components of the hydrogel, the disclosure of the present application also includes all individual values in increments of 0.1% by weight within these weight percentage ranges.
- formulations “according to the invention”, “advantageous according to the invention”, “advantageous in the sense of the present invention” etc. always refer both to the hydrogel according to the invention and to the use according to the invention.
- normal conditions means 20°C, 1013 hPa and a relative humidity of 50%.
- skin it preferably refers to human skin.
- Emulsifiers are understood to mean all substances that are listed in the International Cosmetic Ingredient Dictionary and Handbook, Thirteenth Edition 2010, (ISBN 1-882621-47-6) under the designation "emulsifying agent".
- Surfactants are understood to be all substances that are listed under the name “surfactant” in the International Cosmetic Ingredient Dictionary and Handbook, Thirteenth Edition 2010, (ISBN 1-882621-47-6).
- viscosity values relate to a measurement at 25° C. in a 150 ml wide-mouth bottle (VWR No.: 807-001) using Rheomat R 123 from the company proRheo.
- the Rheomat R 123 from proRheo GmbH is a Rotational viscometer, ie a measuring body rotates in the substance to be measured. The force required to rotate the measuring body in the sample at a specified speed is measured. The viscosity is calculated from this torque, the speed of the measuring body and the geometric dimensions of the measuring system used.
- Measuring body No. 1 (Article No. 200 0191), suitable for a viscosity range up to 10,000 [mPa-s], speed range 62.5 min-1, is used as the measuring body.
- the cosmetic hydrogel comprises dehydroxanthan gum. It is advantageous for the purposes of the present invention if the proportion of dehydroxanthan gum is from 0.1% by weight to 5% by weight, preferably from 0.3% by weight to 3.5% by weight and is particularly preferred from 0.6% to 2% by weight based on the total weight of the hydrogel.
- xanthan gum and/or carrageenan are contained.
- the total proportion of xanthan gum and/or carrageenan is advantageously from 0.1 to 3% by weight, preferably from 0.15% by weight to 1.5% by weight and particularly preferably from 0.2 to 0.7% by weight % by weight based on the total weight of the hydrogel.
- the proportion of xanthan gum is advantageously from 0.1 to 3% by weight, preferably from 0.15% by weight to 1.5% by weight and particularly preferably from 0.2 to 0 .7% by weight based on the total weight of the hydrogel.
- the proportion of carrageenan is advantageously from 0.1 to 3% by weight, preferably from 0.15% by weight to 1.5% by weight and particularly preferably from 0.2 to 0.7% by weight % by weight based on the total weight of the hydrogel.
- the weight ratio of dehydroxanthan gum to the total amount of xanthan gum and/or carrageenan is advantageously from 10:1 to 1:1, preferably from 8:1 to 1.5:1 and particularly preferably 5:1 to 2:1.
- the total proportion of water is advantageously at least 70% by weight, preferably at least 75% by weight and particularly preferably at least 77% by weight, based on the total weight of the hydrogel.
- the total proportion of water is advantageously less than 99% by weight, based on the total weight of the hydrogel.
- the hydrogel according to the invention is preferably free from polymers which are obtained from a homopolymerization or copolymerization with vinylpyrrolidone, acrylic and/or methacrylic acid.
- free means that the total proportion of the substances mentioned is less than 0.05% by weight and particularly preferably 0% by weight, the details relating to the total weight of the hydrogel.
- hydrogel is free from emulsifiers and surfactants.
- the hydrogel comprises other ingredients which are customarily used in such formulations.

It is also advantageous if the hydrogel contains phenoxyethanol, it being advantageous if the proportion of phenoxyethanol is from 0.2 to 1.5% by weight, preferably from 0.4 to 1.0% by weight and particularly preferred from 0.5 to 0.9% by weight based on the total weight of the hydrogel.
- active ingredients are present. These are advantageously selected from the group containing sodium hyaluronate, 1-methylhydantoin-2-imide, creatine, folic acid, panthenol, pantolactone, vitamin C, magnolia, calcium pantothenate and sodium ascorbyl phosphate.
- the active ingredients mentioned in the group are advantageously used in total proportions of up to 2% by weight, based on the total weight of the hydrogel.
- cosmetic auxiliaries such as other active ingredients, dyes, rheology modifiers, alcohols, oils and waxes can also be present, provided they do not adversely affect the properties according to the invention.
- the gels of the invention are characterized in that they are transparent. This property is often appreciated by consumers.
- a gel can be regarded as transparent if it shows a transmission of 85% at 500 nm under normal conditions.
- a comparison shows that when stored for up to 120 days, the increase in viscosity could be reduced by adding carrageenan or xanthan gum. In this way, hydrogels with a higher viscosity could be provided.
- the hydrogels according to the invention appear transparent.
