- Cationized protein hydrolysates can also be used, the underlying protein hydrolyzate coming from animals, for example from collagen, milk or keratin, from plants, for example from wheat, corn, rice, potatoes, soy or almonds, from marine life forms, for example from fish collagen or algae, or from biotechnologically obtained protein hydrolysates.
- the protein hydrolysates on which the cationic derivatives are based can be obtained from the corresponding proteins by chemical, in particular alkaline or acidic, hydrolysis, by enzymatic hydrolysis and/or a combination of both types of hydrolysis.
- the hydrolysis of proteins usually results in a protein hydrolyzate with a molecular weight distribution of about 100 Daltons to several thousand Daltons.
- Cationic protein hydrolysates whose underlying protein content has a molecular weight of 100 to 25,000 Daltons, preferably 250 to 5000 Daltons, are preferred.
- cationic protein hydrolysates are to be understood as meaning quaternized amino acids and mixtures thereof.
- the quaternization of the protein hydrolysates or the amino acids is often carried out using quaternary ammonium salts such as N,N-dimethyl-N-(n-alkyl)-N-(2-hydroxy-3-chloro-n-propyl) ammonium halides.
- the cationic protein hydrolysates can also be further derivatized.
- Typical examples of the cationic protein hydrolysates and derivatives are the products known and commercially available under the INCI names: Cocodimonium Hydroxypropyl Hydrolyzed Collagen, Cocodimopnium Hydroxypropyl Hydrolyzed Casein, Cocodimonium Hydroxypropyl Hydrolyzed Collagen, Cocodimonium Hydroxypropyl Hydrolyzed Hair Keratin, Cocodimonium Hydroxypropyl Hydrolyzed Keratin, Cocodimonium Hydroxypropyl Hydrolyzed Rice Protein, Cocodimonium Hydroxypropyl Hydrolyzed Silk, Cocodimonium Hydroxypropyl Hydrolyzed Soy Protein, Cocodimonium Hydroxypropyl Hydrolyzed Wheat Protein, Cocodimonium Hydroxypropyl Silk Amino Acids, Hydroxypropyl Arginine Lauryl/Myristyl Ether HCI, Hydroxypropyltrimonium Gelatin, Hydroxypropyltrimonium Hydrolyzed Casein, Hydro
- Active ingredients such as bisabolol and/or allantoin,
- Ceramides are N-acylsphingosine (fatty acid amides of sphingosine) or synthetic analogues of such lipids (so-called pseudo-ceramides), antioxidants,
- Preservatives such as sodium benzoate or salicylic acid, pH adjusters such as sodium hydroxide, citric acid and/or lactic acid, viscosity regulators such as salts (NaCl).
- a second subject of the invention is the cosmetic use of the anti-dandruff shampoo according to the invention for cleaning and caring for human hair as well as for the prophylaxis, reduction, elimination and relief of dandruff on hairy body surfaces.
- a third subject of the invention is a cosmetic method for combating scalp dandruff, in which an anti-dandruff shampoo containing a) at least one compound according to formula (I) and b) at least one surfactant is applied to the hair and scalp and after an exposure time of 5 seconds until rinsed out again for 5 minutes.
- the anti-dandruff shampoos according to the invention enable the effective and sustainable treatment of dandruff conditions. They also have a good, mild cleansing, balancing and calming effect, especially on sensitive scalps.
