Definitions

• the present invention relates to a process for the preparation of concentrates of antimicrobial agents, the concentrates themselves and their use for the preparation of solid, liquid or pasty body cleansing compositions, in particular soaps.
• Solid, liquid or pasty detergents in particular soaps, contain substances such as alkali salts of saturated or unsaturated fatty acids, which can easily be decomposed by microorganisms. This results in degradation products that reduce the cleaning effect and often cause an undesirable odor change.
• personal cleansers typically contain antimicrobial agents.
• bar soaps are carried out so that in a first step soap pellets are prepared by the after saponification of the underlying fat or
• Oil base soap which usually has a water content of about 30 to 40 wt .-%, with additives such. Glycerine and complexing agents are added and subsequently dried to a water content of 5 to 25 wt .-%.
• the soap pellets are mixed with other additives such as fragrances, dyes, pigments, optical brighteners, antimicrobial agents or deodorizing additives and over suitable
• Cutting device for the production of bar soaps are fed to a piece press.
• a problem in the process described above is the fact that a homogeneous incorporation of the commonly used antimicrobial agents due to their powdery consistency is difficult but necessary to achieve a uniform effect throughout the product, however, to avoid a sandy grip of the final product.
• antimicrobial agents are, for example, N- (4-chlorophenyl) -N'- (3,4-dichlorophenyl) urea (also called trichlorocarbanilide or TCC), triclosan
• soaps In order to accomplish a substantially homogeneous distribution of the generally in water almost insoluble and sparingly soluble in common surfactants antimicrobial agents in the product
• so-called slurries are usually prepared, which are added continuously to the solid soap base (also called soap noodle), which is typically required via a worm gear, via metering pumps.
• solid soap base also called soap noodle
• These slurries are usually up to 99 wt .-% of perfume oil, dyes or dye preparations and, if necessary, usually liquid, perfume-soluble other ingredients to improve the
• mixers such as kneaders, Z mixers or similar devices with a suitable discharge device.
• the soap noodle is presented in this process, added all the necessary additional formulation ingredients in the form and homogeneously mixed at room temperature or cooling. With the aid of this process, it is possible to add up to 15% by weight of solid or pasty constituents of the soap noodle without the addition of further solvents. Due to the resulting batch operation with high time and personnel expenses, however, this procedure is uneconomical, furthermore, the problem of dust formation occurring is not resolved.
• the body cleansing agents are liquid, pasty or solid, more preferably pasty or solid
• Suitable body cleanser bases include, for example, soaps or synthetic detergents such as, for example, anionic, nonionic, ampholytic or zwitterionic surfactants, but preferably soaps. Soaps are preferably those soaps containing salts of linear fatty acids with 12 to 22 C-
• Atoms e.g. Salts of lauric, myristic, paknitic, stearic, arachinic, beehive,
• soaps which are obtainable from vegetable and animal oils and fats by stranding, for example from coconut oil fatty acids or tallow fatty acids or mixtures thereof, in particular
• coconut fatty acids coconut fatty acids
• Preferred salts of linear fatty acids are alkali metal salts such as potassium and sodium salts, preferred are sodium salts.
• the mixing can be carried out in a conventional manner with conventional mixing devices, preferably with an extruder or a kneader.
• the concentrates according to the invention contain from 5 to 80% by weight of one or more antimicrobial agents
• Active ingredients and 40 to 80 wt .-% of salts of linear fatty acids Preferably, the proportion of antimicrobial agents 20 to 60 wt .-%, particularly preferably 40 to 60 wt .-%.
• Preferred antimicrobial agents are parabens, TCC and TCS or mixtures thereof, more preferred are TCS and TCC, most preferred is TCC.
• a further subject of the present invention is therefore the use of parabens, TCC and TCS for the preparation of the concentrates according to the invention.
• the concentrates may contain additives such as water, polyalcohols, e.g. Glycerol or polyethylene glycols, fragrances such as
• Brighteners such as stilbene or coumarin derivatives or deodorizing additives such as aluminum chloride may be added.
• a body-cleaning agent base such as those mentioned above, with the antimicrobial or antimicrobial agents
• Mixing can be done in a conventional manner with conventional mixing devices, preferably with an extruder or a kneader.
• soap noodles pellets or granules are obtained with a high concentration of antimicrobial agents.
• the process according to the invention and the concentrates according to the invention are particularly suitable for the production of bar soaps and medical washing products.
• a particular advantage of the concentrates according to the invention is that they can be integrated as easily manageable component in the usual process of soap production, and in particular significantly reduce the problems described in the prior art of homogeneous distribution, dust behavior and undesirable aids in the final product.
• the preparation according to the invention of cleaning agents allows the elaborate pretreatment of the added antimicrobial active ingredients, such as, for example, dissolution and pasting, optionally at elevated temperature. This further minimizes the formation of by-products or degradation products.
• Soap pellets were placed in a 10 liter kneader and the desired amount of commercial TCC was added together with a predetermined amount of solvent and mixed for 15 to 30 minutes, at least until homogeneously distributed. Thereafter, the resulting mixture is discharged and pressed by means of an extruder through a perforated disc to the concentrate in pellet form.
• the concentrate prepared according to Example 3 was mixed with the components indicated below by means of a perforated disc extruder. This process was repeated three times. Subsequently, a strand was pressed and produced from the strand bar soaps. Soap (made from 85% tallow fatty acid / 15% coconut fatty acid): 4923.5 g
