Definitions
- the invention relates to water-containing shaving creams with improved producibility on the basis of alkali soaps which, owing to their composition, are easily deformable at temperatures of 20 to 60 ° C.
- Shaving creams are mostly sold in tubes. When using, you press some cream on a damp shaving brush and then soap the body parts to be shaved. Conventional shaving creams, however, have the disadvantage of cementing at temperatures above room temperature, such as occur in summer or in hot countries. This lack of deformability, for example, makes it no longer possible to apply it from a tube.
- Japanese patent application JP 79/97609 describes cream-shaped cleaning agents (cosmetic soaps) with good foaming power with a content of 0.2 to 20% by weight of branched fatty acids with 16 to 20 carbon atoms.
- the object of the present invention was to develop water-containing shaving creams based on alkali soaps which are distinguished both by improved producibility and by improved deformability above temperatures from 30 to 40 ° C.
- these shaving creams should be homogeneous, have a good consistency and an attractive shine.
- Suitable linear fatty acids (A) are: lauric acid, myristic acid, palmitic acid, stearic acid, arachic acid, behenic acid or technical mixtures which predominantly consist of such fatty acids, for example hardened palm oil fatty acid, hardened coconut oil fatty acid or hardened taig fatty acid. Mixtures are preferably used which essentially contain palmitic and stearic acid, e.g. B. Cutina ( R ) FS45, which is commercially available from the applicant.
- the fatty acids (A) are preferably present in the shaving creams according to the invention in an amount of 20 to 30% by weight.
- Suitable branched fatty acids (B) are, for example, 2-hexyldecanoic acid, 2-0ctyldecanoic acid or other branched fatty acids with 16 to 22 carbon atoms. However, preference is given to 2-hexyldecanoic acid, henceforth referred to as isopalmitic acid, which the applicant sells under the name Edenor IP 95.
- the fatty acids (B) are preferably contained in the shaving creams according to the invention in an amount of 14 to 16% by weight. In a preferred embodiment, the total amount of fatty acids (A) and (B) contained in the shaving creams according to the invention is 30 to 45% by weight.
- the mixture of linear and branched fatty acids (A) and (B) is present in the shaving creams according to the invention entirely or predominantly as an alkali salt (alkali soap), preferably as a mixture of sodium and potassium soap.
- alkali soap preferably as a mixture of sodium and potassium soap.
- free fatty acid (C) in an amount of up to 3.0% by weight of the preparation is not a disadvantage, but is, if desired, deliberately chosen to achieve a pearlescent effect.
- polyols (D) with 3 to 6 carbon atoms and 2 to 6 hydroxyl groups for example ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,2-butylene glycol, 1,3-butylene glycol, 1,4- Butylene glycol, glycerin, erythritol, pentaerythritol, trimethylolpropane, sorbitol, anhydrosorbitol, cyclohexanetriol, inositol can be used.
- Propylene glycols and glycerol alone or mixtures of these polyols with sorbitol and / or butylene glycol are preferred.
- polyols are preferably contained in the shaving cream in an amount of 10 to 20% by weight.
- Glycerin is particularly suitable as polyol (D).
- the polyols (D) ensure that the shaving creams according to the invention remain moist and do not dry out.
- compositions according to the invention can also contain 0 to 10% by weight of auxiliary substances (E).
- auxiliary substances E are superfatting agents such as cetyl alcohol, lanolin, stearyl alcohol, lecithin, isopropyl myristate, petroleum jelly or paraffin oil; softening agents such as sodium metasulfate or potassium metasulfate; Consistency regulators such as polyethylene glycols or their esters; Lubricants such as mineral oils; Stabilizers such as methyl cellulose or polyvinyl pyrrolidone.
- the preparation of the shaving creams according to the invention is expediently carried out in such a way that sodium hydroxide or potassium hydroxide solution or a mixture of sodium hydroxide and potassium hydroxide solution is added with simple stirring into a container in which a mixture of liquid fatty acids at 50 to 90 ° C., in particular ⁇ about 80 ° C have been submitted.
- Glycerin can either be added together with the sodium or potassium hydroxide solution or in a subsequent step.
- fragrances and optionally further auxiliaries can be mixed in one after the other during the cooling.
- Cutina FS45 fatty acid mixture with the following C chain distribution: 51% C16: 0; 2% C17: 0; 44.5% C18: 0; 0.5% C18: 1; 2% ⁇ C16; the number after the colon indicates the number of double bonds (Cutina ( R ) FS45; Henkel / Düsseldorf)
- Isopalmitic acid 2-hexyldecanoic acid (Edenor IP 95; Henkel / Dusseldorf) Glycerin, 86% iq (Henkel / Dusseldorf)
- Shaving creams were prepared in the following manner in accordance with the compositions given in Tables 1 and 3: Cutina FS45, Edenor HK 12-18 and isopalmitic acid were placed in a container and heated to 80.degree. A mixture of sodium hydroxide solution and potassium hydroxide solution and glycerol was added in portions, with stirring, the mass becoming homogeneous with hydrolysis. After adding the remaining water, the mixture was allowed to cool and the perfume oil was metered in.
- compositions B1 and B2 according to the invention could easily be prepared with a simple stirrer, while in the comparisons VI and V2 a highly viscous viscous mass was obtained. stood, which could only be produced with the use of special stirring and homogenizing devices with great energy input.
- creams Bl and B2 were easily deformable even at higher temperatures, while the comparisons VI and V2 were set like cement (see Table 2). Almost deformable is understood to mean that a shaving cream can easily be squeezed out of a tube by hand.
- Examples B3 to B9 and the associated comparisons V3 and V4 clearly demonstrate that the object is achieved according to the invention only with a certain critical amount of branched fatty acid (B). While in the examples according to the invention homogeneous creams with a beautiful luster were obtained which were easily deformable in the entire temperature range from 20 to 45 ° C., the comparisons had serious deficiencies: the composition according to V3 was dull in appearance and very fixed, the composition according to V4 very thin and inhomogeneous (phase separation)
