Patent Application
20170079903
The present invention generally relates to cosmetic compositions for caring for skin.
As the largest organ of humans, the human skin performs a variety of vital functions. Having, on average, a surface area of approximately 2 m2 in human adults, the skin plays a major role as a protective and sensory organ. Tasks of this organ include conveying and warding off mechanical, thermal, actinic, chemical and biological stimuli. The skin, for example, also protects the human organism from the damaging effects of a wide variety of microorganisms, and yet, despite protective mechanisms of its own, is possibly also damaged itself by these microorganisms.
Inflammatory conditions of the skin are caused by harmful bacteria, such as Propionibacterium acnes, which are permanently present on the skin, but proliferate more drastically under certain conditions and cause “blemished skin” or acne, for example. These are essentially microorganisms (bacteria and fungi) that must be classified as pathogenic.
At the same time, the resident bacterial skin flora is also composed of other bacterial species; however, these do not cause damage, but the growth thereof rather keeps harmful microbes in check and, as a result, these perform an important protective function. These include above all coagulase-negative staphylococci such as S. epidermidis. In general, harmless, desirable skin microbes are also referred to by the term “saprophytic.” However, there are also desirable skin microbes that, according to the present classification, are not assigned to the group of “saprophytic” skin microbes, just as there are microbes classified as being “pathogenic” which may be desirable under certain circumstances, so that a distinction between “desirable” and “undesirable” does not equate to a distinction between “saprophytic” and “pathogenic.” In this regard, it must in particular also be considered that harmless skin-friendly microbes can become pathogenic with excessive reproduction. The classification of bacteria as pathogenic is thus possibly dependent on the composition of the microbial skin flora.
Non-selective antibacterial active ingredients, such as are used for preventing and controlling acne in commercially available cosmetics, for example, not only kill undesirable skin microbes, but also desirable skin microbes and thereby disrupt the biological equilibrium, which can have a variety of undesirable consequences.
A need therefore exists for agents that selectively bring about an advantageous microbiological equilibrium at the application site, this being the skin, for example by promoting the growth and/or the viability of desirable microbes of the skin flora over the growth and/or the viability of undesirable microbes of the skin flora. Corresponding substances are also referred to as “prebiotic.”
So far, the detection of a prebiotic effect of substances has essentially been limited to the intestine. Various publications, for example, describe the use of substances that promote the growth of desirable intestinal bacteria.
The use of prebiotic plant extracts in skin cosmetics is described in the German patent application DE 10333245 A1. This application considers the group of prebiotic plant extracts to include, among other things, extracts of ginseng (Panax ginseng) and black currant (Ribes nigrum).
German patent application DE 102012223405 A1 describes a skin care agent that, in addition to other components, includes extracts of ginseng (Panax ginseng), Scots pine (Pinus sylvestris), tea (Camellia sinensis) and black currant (Ribes nigrum), and the emulsifier caprylyl/capryl glucoside.
While the skin care agents known from the prior art already satisfy high requirements in terms of the cosmetic effectiveness thereof, a need continues to exist for skin care cosmetics having improved cosmetic effectiveness and a long shelf life.
It is therefore desirable to provide skin care cosmetics that include cosmetically active plant extracts, are present in storage-stable form, are both chemically and physically stable, and distinguish themselves by good cosmetic properties, and in particular by low viscidity and good skin tolerability.
Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with this background of the invention.
