Definitions
- the invention comprises an emulsifier-free, skin-conditioning cosmetic or dermatological preparation.
- the preparation is characterized by a special preparation, which in turn causes only the beneficial properties of a skin conditioning.
- the preparation is suitable for application on wet skin without being completely rinsed off, thus enabling creaming during showering.
- Cosmetic or dermatological preparations can be due to their
- Cosmetic preparations for the care of the skin are developed primarily for use on dry skin. These forms of preparations are known as leave-on preparations, such as creams, lotions or body milk. Often these are formulated as emulsions, especially W / O, O / W, O / W / O or W / O / W emulsions.
- Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only slightly miscible with one another, which are usually referred to as phases.
- one of the two liquids water or oil
- the liquids pure or as solutions
- an oil-in-water emulsion O / W emulsion, eg milk.
- the basic character for example electrical conductivity, sensor technology, dyeability of the continuous phase, an O / W emulsion is characterized by the water.
- a water-in-oil emulsion W / O emulsion, eg butter
- W / O emulsion eg butter
- the basic character being determined by the oil.
- rinse-off preparations are designed for use under shower or while bathing. In contrast, rinse-off preparations but less include the
- Care aspect considered as well as rinse-off can be applied, for example, in the shower.
- a characteristic of cosmetic products which is very important for consumers but difficult to quantify, is their texture and sensor technology.
- texture is understood to mean those properties of a cosmetic which can be traced back to the structure of the preparation, can be sensed by tactile and tactile sensations and, if appropriate, expressed in mechanical or rheological flow properties.
- the texture can be tested in particular by means of sensors.
- the texture of cosmetic products which optionally can be influenced with the aid of additives, is of almost the same significance for the consumer as their objectively ascertainable effects.
- the term "sensorics” refers to the scientific discipline that deals with the evaluation of cosmetic preparations based on sensory impressions.
- the sensory evaluation of a cosmetic is based on the visual, olfactory and haptic impressions.
- Olfactory impressions which can often be differentiated into initial odor (head note), main odor (middle note, body) and after-odor (ending).
- head note main odor
- body main odor
- after-odor ending
- the sensory analysis makes use of the possibility, the sensory
- a further object of the present invention was therefore to provide preparations which, in addition to the usual criteria for cosmetics, such as compatibility,
- shelf life and the like also provide the consumer essential, hitherto unknown cosmetic, especially sensory, benefits.
- the preparations sought should be suitable for use in the personal care sector, i. for an application on the whole body and thereby be sensory attractive.
- the invention is a skin conditioning, cosmetic or dermatological preparation obtainable by
- At least the mixture of hydrocarbons has a melting range from 5 ° C to 75 ° C, preferably up to 55 ° C (according to DSC),
- step b. One or more fatty alcohols, at least one wax (b1) and a mixture of liquid and solid hydrocarbons (b2) are preferably melted.
- the fatty alcohol (s) and the wax (s) preferably also have one
- Polyacrylic acids are to be predispersed in a lipid and then added to the water phase. According to the present invention, however, the polyacrylic acid polymers are dispersed in water contrary to this specification. This surprisingly leads to the fact that the polyacrylic acid polymers are more "activated" by this production method than when they are wetted with lipid.
- Ultraturax high energy input
- step a The incorporation of the polyacrylic acid polymers in the water phase in step a.) With the aid of a higher energy input with as complete as possible homogenization.
- step c. No complete homogenization is prescribed.
- the fatty alcohols are used together with the waxes (b1) and / or mixtures of liquid and solid hydrocarbons (b2)
- the temperature is based on the melting temperature of the individual components, preferably above 74 ° C.
- step c.) It was surprisingly found that if too much energy is supplied, ie complete homogenization, no satisfactory product is obtained during the mixing and mixing of the two phases. The product obtained is then too smooth, too fine and too amorphous.
- Essential to the invention is not complete homogenization. This means that by means of polarization microscopy investigations optically anisotropic, i. crystalline areas, a so-called granular structure can be found.
- two microscopic coverslips are placed at a distance of about 1 cm on a microscope slide. A small amount of the respective sample is placed between the coverslips and compressed to obtain a well-defined layer thickness of the preparation of about 0.15 mm.
- the samples are viewed through a transmitted light microscope equipped with two linear polarizing filters (e.g., Motic DM-143 FBGG stereomicroscope, with 4x zoom and 3 megapixel camera).
- two linear polarizing filters e.g., Motic DM-143 FBGG stereomicroscope, with 4x zoom and 3 megapixel camera.
- Figures 1, 2, 3 and 6 show the resulting images.
- Figures 1, 2 and 6 show preparations according to the invention having a recognizable granular structure, so-called crystallites.
- the preparations according to the invention have a so-called grainy performance and can be described as gritty.
- the gritty texture according to the invention is achieved if one or more crystallites with a particle size of 5 to 500 ⁇ m are contained on a 4 mm 2 surface of the preparation in a layer thickness of 0.15 mm (+/- 0.02 mm).
- the particle size is measured as the diameter of the particles.
- Particle size is to be understood as follows. Particles are
- three-dimensional structures that can be solid and / or liquid and have a structure that can be distinguished from the environment.
- the particles essentially consist of the fatty phase. It should be different from the environment as these particles are stabilized by the gel network (environment). Part of the fatty phase may also be in the gel network. Decisive is therefore not a 100% separation between gel network (environment) and fat phase but the inventive formation of the granular structure with a particle density of one or more crystallites having a particle size of 5 to 500 ⁇ on 4 mm 2 surface of the preparation.
- the particle size is clearly defined by the indication of the ball diameter, as is preferred according to the invention in the range from 5 to 500 ⁇ m.
- the majority of the fine-grained structures or crystallites does not consist of spheres, but of more or less irregularly shaped particles, which in one extreme case may be needle-shaped, and in the other platelet-shaped.
- the dispersity property of the individual particles can be described here by the particle volume and additional parameters such as sphericity (sphere similarity). Instead of the one-parameter function for spheres, one obtains a multi-parameter dispersity function, whose determination with large metrological effort is connected. Such an effort is justified only if it serves to gain essential information about product properties.
- the texture of the preparation according to the invention referred to as a granular structure, particles, crystallites or grittyness, therefore essentially comprises fatty phase constituents which differ visually from the environment.

- DSC is a comparative measurement method that enables the determination of heat quantities of physical and chemical processes. If a material is his
- the method runs cyclically, so that after the first heating curve, a defined cooling takes place and then the sample is heated again in the specified temperature range. This gives two different kinds of information: In the first heating curve, all thermal effects, including the prehistory, are discernible. In the second heating curve, the history has been eliminated and the pure thermal behavior of the sample under defined cooling conditions can be evaluated.
- the melting range of fatty alcohols, waxes or hydrocarbons between 4.5 ° C and 75 ° C according to DSC is the range determined in the first heating curve.

- thickeners, fillers and neutralizing agents are added to the preparations.
- Thickeners are advantageously suitable for stabilizing the system and enhance the skin-conditioning properties and the special skin feel of the preparations according to the invention.
- aluminum Starch Octenylsuccinat is preferably added, which also leads to an optimization of the skin feel by the skin care film looks a little more velvety.
- Sodium hydroxide solution is advantageously added as a neutralizing agent so that the thickeners can form their gel network and a stable system is formed.
- the preparation according to the invention is emulsifier-free. That the optionally acting as emulsifying polyacrylic acid polymers are not understood according to the invention as emulsifiers.
- Polyacrylic acid polymers are understood as meaning the polymers of acrylic and / or methacrylic acid known in cosmetics and acrylate crosspolymers.
- these are high molecular weight polymers (macromolecules) (> 1 Mg / mole) composed of a backbone of polyacrylic acid and small amounts
- Polyalkenylether cross-links exist. They are also referred to as carbomers. These water-soluble or dispersible polymers can cause a significant increase in viscosity in the liquid in which they are dissolved or dispersed. This is caused by the formation of carbomer microgels in the water.
- Particularly preferred polyacrylic acid polymers are, in addition to the carbomers, those acrylate crosspolymers which exert a polymeric emulsifier action.
- Polymer emulsifiers are mainly high polyacrylic acid polymers
- emulsifying polyacrylic acid polymers have a small lipophilic portion in addition to the hydrophilic body.
- acrylate crosspolymers which have the INCI name
- the polyacrylic acid polymers are particularly preferably selected from the group of acrylates / C 10-30 alkyl acrylate crosspolymers and / or carbomers. Especially preferred are acrylates / C 10-30 alkyl acrylate crosspolymer Pemulen® TR-1, e.g. from Lubrizol and Carbopol® 3128 from Lubrizol.

- the proportion of total polyacrylic acid polymers is preferably 0.05 to 2 wt.%, In particular 0.2 to 1 wt.%, Based on the total mass of the preparation.
- two polyacrylic acid polymers or three polyacrylic acid polymers are understood to mean that one polyacrylic acid polymer differs from the other in at least one property.
- the substance group acrylates / C 10-30 alkyl acrylate crosspolymers comprises, for example, the commercial products pemulen TR-1 or TR-2.
- Carbomers are differentiated, for example, into types A, B and C. Differences here are, for example, their gels with different viscosities (United States Pharmacopoeia, USP).
- Also essential to the invention is a proportion of waxes or preferably a mixture of liquid and solid hydrocarbons having a melting range of 4.5 to 75 ° C, in particular up to 55 ° C according to DSC.
- oils it is possible with advantage to add non-polar to medium-polar lipids in the preparations according to the invention. Otherwise, the stability is more difficult to adjust due to the absence of emulsifiers.
- lipids is used as a generic term for fats, oils, waxes and the like, as is well known to the person skilled in the art. Also, the terms “oil phase ,, and” lipid phase , are used interchangeably.
- oils and fats differ in their polarity. It is proposed to assume the interfacial tension against water as a measure of the polarity index of an oil or an oil phase. In this case, the lower the interfacial tension between this oil phase and water, the greater the polarity of the relevant oil phase. According to the invention, the interfacial tension is considered as a possible measure of the polarity of a given oil component.
- the interfacial tension is the force acting on an imaginary line of one meter length located in the interface between two phases.
- the physical unit for this interfacial tension is calculated classically by the force / length relationship and is usually expressed in mN / m (millinewtons divided by meters). It has a positive connotation if it tries to reduce the interface. In the opposite case, it has a negative sign.
- Preferred lipids are moreover medicinal white oils and silicone oils, particularly preferred are naphtha-containing medicinal white oils, as well as their mixture products.
- the preparation according to the invention makes it possible for the first time to apply the care under the shower.
- the preparations according to the invention are advantageously formulated only with preservatives which have a water solubility of more than 0.75% at 20 ° C.
- the preparations according to the invention are furthermore preferably also free of surfactants.
- Surfactants are substances that are the surface tension of a liquid or the
- surfactants are described as amphiphilic substances that can dissolve organic, nonpolar substances in water. Due to their specific molecular structure, they provide at least one hydrophilic and one hydrophobic one
- hydrophilic fractions of a surfactant molecule are usually polar functional groups, for example -COO " , -OSO 3 2" , -SO 3 " , while the hydrophobic moieties generally represent nonpolar hydrocarbon radicals
- Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in an acidic or neutral medium. Cationic surfactants are almost exclusively characterized by the presence of a quaternary ammonium group. In aqueous solution, they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and behave accordingly in aqueous solution depending on the pH as anionic or cationic surfactants. in the Strong acidic environment, they have a positive and in the alkaline environment, a negative charge.
- washing-active substances such as, for example, cationic surfactants, in particular quaternary ammonium compounds.
- a detergent substance is used in detergents, dishwashing detergents, shampoos, shower gels and denotes the proportion of the formulation which influences the washing or cleaning performance.
- Substances increase the "solubility" of fat and dirt particles in water that adhere to the laundry or body, they can be of natural or synthetic origin and are classified according to the nature of their charge in anionic, cationic, ampholytic or nonionic.
- Emulsifiers cause two immiscible liquids (for example, oil in water) to mix together to form an emulsion. Due to the amphiphilic character, they penetrate into the oil with their fat-soluble part. As a result of the hydrophilic part, the oil droplets that are now formed by stirring can be dispersed in the aqueous environment. "Primarily, emulsifiers have no detergent surfactants
- Emulsifiers and surfactants can damage the skin's barrier layer.
