Definitions

• the present invention relates to the use of calcium-releasing or binding substances for the targeted weakening or strengthening of the barrier function of the skin.
• the skin is the largest human organ. Among its many functions (for example for heat regulation and as a sensory organ), the most important is the barrier function that prevents the skin (and ultimately the entire organism) from drying out. At the same time, the skin acts as a protective device against the penetration and absorption of substances coming from outside. This barrier function is brought about by the epidermis, which as the outermost layer forms the actual protective cover against the environment. At around a tenth of the total thickness, it is also the thinnest layer of the skin.
• the epidermis is a stratified tissue in which the outer layer, the horny layer (stratum corneum), is the important part for the barrier function. It is worn away in contact with the environment and is therefore in a constant renewal process, with fine flakes being continuously released to the outside and corneal and lipid material horned from the inside being reproduced.
• the skin model recognized by experts today (PM Elias, Structure and Function of the Stratum Corneum Permeability Bar er, Drug Dev. Res. 13, 1988, 97-105) describes the horny layer as a two-component system, similar to a brick wall (brick - mortar model).
• the horny cells (komeocytes) correspond to the bricks
• the complex lipid membrane in the intercellular spaces corresponds to the mortar.
• This system essentially represents a physical barrier against hydrophilic substances, but can because of its narrow and multilayer structure equally, it is difficult for lipophilic substances to pass through.
• the special structure of the horny layer protects the skin on the one hand and on the other hand stabilizes its own flexibility by binding a defined amount of water.
• the regulation of water and moisture content is one of the most important functions of the epidermal lipid membrane. However, it not only has a barrier effect against external chemical and physical influences, but also contributes to the cohesion of the horny layer.
• the lipids of the horny layer consist essentially of ceramides, free fatty acids, triglycerides, cholesterol, cholesterol esters and cholesterol sulfate and are distributed over the entire horny layer.
• the composition of these lipids is of crucial importance for the intact function of the epidermal barrier and thus for the water impermeability of the skin.
• the barrier effect of the skin can be quantified by determining the transepidermal water loss (TEWL - transepidermal water ioss). This is the evaporation of water from the inside of the body without including the loss of water when sweating.
• the determination of the TEWL value has proven to be extremely informative and can be used to diagnose cracked or chapped skin, to determine the compatibility of chemically differently structured surfactants and the like.
• the water content in the top layer of skin is of the utmost importance. It can be influenced to a limited extent by introducing moisture regulators.
• Anionic surfactants which are generally components of cleaning preparations, can increase the pH value in the horny layer for a long time, which greatly hinders regenerative processes that serve to restore and renew the barrier function of the skin. In this case, between regeneration and the loss of essential substances through regular extraction, a new, often very, arises in the horny layer unfavorable state of equilibrium, which decisively affects the external appearance of the skin and the physiological functioning of the horny layer.
• Skin care in the sense of the present invention is to be understood primarily as meaning that the natural function of the skin acts as a barrier against environmental influences (e.g. dirt, chemicals, microorganisms) and against the loss of the body's own substances (e.g. water, lipids) , Electrolytes) is strengthened or restored.
• environmental influences e.g. dirt, chemicals, microorganisms
• the loss of the body's own substances e.g. water, lipids
• Electrolytes e.g. water, lipids
• the effect of ointments and creams on the barrier function and the hydration of the horny layer is based essentially on the covering (occlusion) of the treated skin areas.
• the ointment or cream is, so to speak, a (second) artificial barrier that is supposed to prevent water loss from the skin.
• This physical barrier can be removed correspondingly easily, for example with cleaning agents, as a result of which the original, impaired state is reached again.
• the skin care effect can decrease with regular treatment. After stopping the application of the product, the skin quickly returns to the state before the start of treatment. With certain products, the condition of the skin may even temporarily deteriorate. A sustainable product effect is therefore generally not achieved or only to a limited extent.
• the effect of nourishing cleaning products essentially consists in an efficient regreasing with sebum lipid-like substances.
• the simultaneous reduction in the surfactant content of such preparations can further limit the damage to the homolayer barrier.
• the prior art lacks preparations which positively influence the barrier function and the hydration of the horny layer and which strengthen or even restore the physicochemical properties of the horny layer and in particular of the lamellae from intercellular lipids.
• the skin of newborns and toddlers is particularly thin and is characterized by a weak and permeable barrier in the horny layer.
• the pH buffer capacity of the baby skin is severely limited, so that changes in the pH value on the skin very quickly lead to skin irritation.
• the accumulation of urine and faeces in the baby diaper can lead to the release of ammonia from urea with the help of microorganisms. This ammonia very quickly penetrates the living cells through the horny layer barrier and can increase the pH of the tissue. With a longer incubation period, this pH increase can lead to diaper rash (dermatitis ammoniacalis).
• the epidermis is richly equipped with nerves and nerve end devices such as Father Pacini lamellar bodies, Merkel cell neurite complexes and free nerve endings for sensation of pain, cold, heat and itching.
• nerves and nerve end devices such as Father Pacini lamellar bodies, Merkel cell neurite complexes and free nerve endings for sensation of pain, cold, heat and itching.
• This "sensitive skin” differs fundamentally from “dry skin” with thickened and hardened hom layers.
• Typical reactions of "stinging" to sensitive skin are reddening, tension and burning of the skin as well as itching.
• Typical disturbing neurosensory phenomena associated with the terms "stinging” or “sensitive skin” are reddening of the skin, tingling, tingling, tension and burning of the skin and itching.
• the object of the present invention was therefore to eliminate the disadvantages of the prior art.
• skin-care preparations and preparations for cleaning the skin should be made available which maintain or restore the skin's barrier properties, especially when the natural regeneration of the skin is not sufficient. They are also intended for the treatment and prophylaxis of consequential damage Drying out of the skin, for example fissures or inflammatory or allergic processes or also neurodermatitis, may be suitable.
• Ca 2+ serves as a versatile messenger (second messenger), with its concentration changing in the range 0.1-10 mmol / l.
• sarcoplasmic reticulum is infiltrated by calcium pumps, bound to calreticulin and calsequestrin and can be released through calcium channels, which are activated by the messenger substances inositol 1, 4,5-trisphosphate and cyclic ADP-ribose.
• the function of the Ca 2 + as a cellular regulator is linked to many calcium-binding proteins.
• cosmetic products or other products that come into contact with human skin are added, such as diapers, handkerchiefs, plasters, wound dressings, bath water, textiles, rubber gloves, disinfectants, with builders, sparingly soluble calcium salts (e.g.
• phosphates such as NaH 2 PO 4 , but also zeolites and / or layered silicates with calcium binding capacity and / or as substances known in detergent technology under the term “builder”, for example water-soluble, linear polymers with numerous carboxy groups) or calcium complexing agents (for example polyphosphates, tannic acids, EDTA (ethylenediaminetetraacetic acid), EGTA (ethylenebis (oxyethylenenitri - lo) -tetraacetic acid), citric acid, oxalic acid, free fatty acids etc.) and if this is applied to the skin or if it brings it into contact with human skin, the trans-epidermal water loss as a measure of the quality of the skin barrier is reduced to 80 - 90% of the initial value is reduced, which is accompanied by a thickening of the stratum comeum.

• the pH of the skin and the skin flora are normalized. Allergens and irritants are less able to penetrate, there are less and less violent irritative or allergic reactions barrier-damaging effects of occlusion and calcium-containing substance Fixed a colonization with pathogenic germs, soreness and inflammation is counteracted.
• Complexing agents form complexes with metal atoms which, if one or more polybasic complexing agents, ie chelators, are metalacycles.
• Chelates are compounds in which a single ligand occupies more than one coordination site on a central atom. In this case, normally elongated compounds are closed to form rings by complex formation via a metal atom or ion. The number of ligands bound depends on the coordination number of the central metal. The prerequisite for chelation is that the compound reacting with the metal contains two or more atom groups which act as electron donors.

• Aqueous cosmetic cleaning agents according to the invention or water-free or water-free cleaning agent concentrates intended for aqueous cleaning can contain anionic, nonionic and / or amphoteric surfactants.
• Surfactants are amphiphilic substances that can dissolve organic, non-polar substances in water. Due to their specific molecular structure with at least one hydrophilic and one hydrophobic part of the molecule, they ensure a reduction in the surface tension of the water, wetting of the skin, facilitating dirt removal and removal, easy rinsing and, if desired, foam regulation.
• hydrophilic parts of a surfactant molecule are mostly polar functional groups, for example -COO " , -OSO 3 2" , -SO 3 ' , while the hydrophobic parts generally represent non-polar hydrocarbon radicals.
• Surfactants are generally classified according to the type and charge of the hydrophilic part of the molecule. There are four groups:
• Anionic surfactants generally have carboxylate, sulfate or functional groups
• Sulfonate groups In an aqueous solution they form negatively charged organic ions in an acidic or neutral environment. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In an aqueous solution they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and accordingly behave like anionic or cationic surfactants in aqueous solution depending on the pH. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment. In the neutral pH range, however, they are zwitterionic, as the following example should illustrate:
• Non-ionic surfactants do not form ions in an aqueous medium.
• Anionic surfactants to be used advantageously are acylamino acids (and their salts), such as
• acyl glutamates for example sodium acyl glutamate, di-TEA-palmitoylaspartate and sodium caprylic / capric glutamate
