Definitions
- Composition for topical use on the skin is Composition for topical use on the skin
- the invention relates to a composition for topical application on the skin according to claim 1.
- the surface of the skin is characterized by a special microorganism flora consisting of bacteria and fungi, each of which colonizes different skin regions in different numbers.
- This microorganism flora also known as resident "skin flora” or “skin microflora”
- skin flora is part of the so-called microbiome and makes a significant contribution to protecting the skin and thus the entire organism from pathogens.
- Organisms on the skin are responsible for widespread human skin diseases such as acne, rosacea, perioral dermatitis and pityriasis versicolor, pityrosporum folliculitis as well as for atopic and seborrheic eczema or at least are significantly involved in their pathogenesis.
- the Malassezia species can grow on the skin.
- the increase in growth is particularly evident when using products that contain natural oils, fats and / or long-chain fatty acid esters.
- the common components of the skin and body care products available on the market consequently lead to the development or exacerbation of skin diseases.
- the common components of these care products include the following substances: In the case of oils and emollients, synthetic long-chain fatty acid esters, natural substances such as grape seed oil or hydrocarbon-based substances such as paraffin are often used.
- synthetic esters for example cetyl palmitate
- natural waxes for example beeswax
- fatty alcohols for example cetearyl alcohol
- gel formers are usually used.
- Long-chain synthetic fatty acid esters are primarily known as emulsifiers.
- the invention is based on the object of eliminating the above disadvantages from the prior art and of providing a composition for topical application on the skin which counteracts the development or aggravation of skin diseases.
- Composition is said to be skin-nourishing, skin-protecting, cleansing and cosmetic
- the invention in a first aspect, relates to a composition for topical application on the skin, comprising at least one humectant, at least one consistency regulator, and at least one emulsifier, the emulsifier having a fatty acid esterified with a hydroxy group, the fatty acid having at least one carbon chain of 18 or more has fewer carbon atoms.
- the chain length only the carbon atoms in the chain are taken into account. That the individual carbon atoms of a carbon chain, which consists of n carbon atoms, other atoms such as Can have hydrogen atoms or even other side groups is obvious and is not taken into account in the nomenclature.
- a fatty acid esterified with a hydroxy group is also referred to as a fatty acid ester.
- medium-chain or short-chain fatty acid esters or derivatives of such fatty acid esters can be provided as emulsifiers.
- a structural element of a compound that has several carbon-carbon bonds is referred to as a carbon chain.
- the carbon atoms are therefore "chained" to one another - one also speaks of hydrocarbon chains.
- Examples of molecules with such carbon chains are caproic (6 carbon atoms), caprylic (8 carbon atoms), capric (10 carbon atoms) and lauric acid (12 carbon atoms).
- an emulsifier is to be understood as meaning a surface-active auxiliary which is used to make two immiscible or at least poorly miscible with one another
- Emulsifiers are often referred to as surfactants. Any structural or functional differences that may exist between emulsifiers and surfactants depending on the definition are not taken into account in the present application.
- compositions which has at least one emulsifier which has a fatty acid esterified with a hydroxy group and which has at least one carbon chain of 18 or fewer carbon atoms does not interact with the skin flora, or only interacts to a small extent. This prevents the overgrowth of individual pathogens, which can counteract a disruption of the balance of the microflora on the skin.
- the fatty acid content is insoluble and can precipitate, which in turn can lead to clogging of the skin pores in the case of large molecules. For molecules with more than 18 carbon atoms in one
