Patent Application
20230293424
The present invention relates to the veterinary field, and more particularly to shampoo compositions comprising an active ingredient obtained from Ophiopogonjaponicus, and an amphoteric surfactant, intended for non-human mammals. It also relates to a method for washing the coat of non-human mammals by applying said shampoo compositions to the coat and/or the skin.
The active ingredient obtained from Ophiopogonjaponicus, and the hydrating effect thereof or the effect thereof for reinforcing the barrier function of human skin has been described in the patent EP2271311. The use of said active ingredient for treating atopic dermatitis in animals and humans has been described in the patent application WO2017/121965.
However, no mention is made of a shampoo comprising said active ingredient which is suitable for non-human mammals, in particular dogs and cats. The skin and the coat of non-human mammals protect said mammals from external aggressions. Their upkeep is therefore very important for the well-being, and indeed the health, of non-human mammals. The skin and the hairs of domestic animals such as dogs and cats are covered by a layer of fatty acids and waxes which contribute to the barrier function, thus having a role of protecting the skin from external aggressions, and which give the silky appearance of the coat.
A veterinary shampoo must therefore be effective in terms of washing power for the skin and the coat, without causing irritation or any other skin disorder. It must therefore also preserve or maintain the barrier function and/or the silky appearance of the coat. The skin must in particular keep its protective effect with respect to external aggressions.
Furthermore, bacteria exist which may be pathogenic or become pathogenic if they are too numerous, such as the staphylococcaceae, for dogs and/or cats, and which require particular treatments in view of their reduction or elimination. These staphylococcaceae are represented primarily by S. pseudintermedius.
There is therefore a need for shampoo compositions for non-human mammals, and in particular for dogs and cats, which are both effective in terms of washing, and which make it possible to preserve, or indeed improve, the barrier function of the skin and of the coat and/or the silky appearance of the coat, and which make it possible to preserve the bacterial flora which is beneficial to the mammals, while limiting, or indeed preventing, the colonization of the skin by pathogenic bacteria.
In this context, the applicant is proposing a new shampoo composition comprising an active ingredient obtained from Ophiopogonjaponicus, and at least one amphoteric surfactant selected from the betaines.
The present invention thus relates to a veterinary composition comprising an active ingredient obtained from Ophiopogonjaponicus, and at least one amphoteric surfactant selected from the betaines, which is intended to be used as a shampoo for a non-human mammal, in particular a dog or a cat.
A further object of the invention thus relates to a method for cleaning and/or washing the skin and/or the coat of a non-human mammal, and in particular a dog or a cat, by applying the composition of the present invention to the skin and/or the coat of said mammal.
A further object of the invention relates to the use of a composition as defined in the present application, or a method using said composition for reducing and/or preventing the presence of pathogenic bacteria and/or the formation and/or the adhesion of pathogenic bacteria biofilms in the case of a non-human mammal, such as a dog or cat.
The invention as described in the present application relates to a shampoo veterinary composition comprising an active ingredient obtained from Ophiopogonjaponicus, and at least one amphoteric surfactant selected from the betaines.
Ophiopogon
japonicus is a perennial, low and abundant herbaceous species having rhizomes, from the family of the Liliaceae. It is cultivated as an ornamental covering plant having tuberous rhizomes, and has a very large number of uses in traditional Chinese medicine.
The species is originally from Japan and Korea, and is also cultivated in Vietnam and in China, in particular in Sichuan, Zhejiang and Hubei provinces. It is also referred to as “Muguet du Japon” in France, and “Mondo grass,” “Fountain plant,” “Monkey grass” or “Dwarf lilyturf” in English. The tuberous root is of a length of a few centimeters; it is light yellow to yellow-brown in color on the outside, having longitudinal wrinkles. Its smell is slight, and its taste slightly sweet and mucilaginous.
In traditional Chinese medicine, the root is known to “feed the Lungs and the Yin, to feed the Stomach and produce Fluids, to remove the Heat from the heart, and to soothe the Spirit.” The main therapeutic indications relate to dry coughs, sore throats, insomnia, irritability, constipation and diphtheria, according to the 16th edition of the Japanese Pharmacopeia.
The roots of Ophiopogonjaponicus originate from strains cultivated in China and Vietnam. Extracts of Ophiopogonjaponicus are known in cosmetics for the skin, in particular in the patent EP2271311, as a moisturizer by action on the rate of NMF (Natural Moisturizing Factors) and on the formation of tight junctions of the cutaneous layers. The application WO 2017/121965 also describes that extracts of Ophiopogonjaponicus can be used for treating atopic dermatitis.
Within the meaning of the invention, “active agent” or “active ingredient” or “extract” means at least one molecule, preferably a set of molecules, having an effect on the cells of the skin.
Within the meaning of the invention, “active agent obtained from Ophiopogonjaponicus” means any molecule or mixture of molecules obtained from Ophiopogonjaponicus. They may be native molecules of the plant, or molecules obtained by any kind of transformation of native molecules of the plant, for example by hydrolysis. The active agent according to the invention is preferably a hydrolysate.
“Hydrolysate” means any extract originating from Ophiopogonjaponicus which is obtained by means of a method comprising at least one step of enzymatic or chemical hydrolysis of Ophiopogonjaponicus, preferably at least one step of enzymatic hydrolysis. “Ophiopogonjaponicus” means all or part of the plant. It may be the entire plant, or a part of the plant. It is preferably tubers of Ophiopogonjaponicus.
“Oligosaccharides” means oligomers formed of a number of monosaccharides by glycosidic bonding, the number of units of monosaccharides being less than 25 units. “Polysaccharides” means polymers formed of a plurality of simple sugars which are interconnected by osidic bonding, the number of units of monosaccharides being greater than 25 units.
The active agent obtained from Ophiopogonjaponicus, used in the composition according to the invention, is preferably an active agent obtained from Ophiopogonjaponicus comprising sugars. Even more preferably, it comprises fructosans, and more particularly it comprises at least 57% fructosans by weight with respect to the total weight of sugars of the active agent, even more preferably at least 80%. The fructosans are polysaccharides made up of fructose and glucose. The sugars containing the active agent are preferably made up of 45 to 80% fructose, 20 to 50% glucose, and 0 to 5% galactose. Said sugars may be in the form of monomers, oligomers and polymers. Predominantly, the sugars contained in the active agent are oligo- and polysaccharides of molecular weights of less than 400 kDa, in the form of fructosans. Thus, the active agent according to the invention preferably comprises oligo- and polysaccharides of molecular weights of less than 400 kDa, in the form of fructosans, representing at least 57 wt.% of the sugars present in the active agent. According to a particularly suitable variant, the active agent is obtained from tubers of Ophiopogonjaponicus.
According to an embodiment, the active agent used for preparing the composition according to the invention is present in the form of a powder, in particular a clear-colored powder, and has at least one of the following features, preferably all:
