Definitions
- the invention relates to mild aqueous shaving preparations with a content of alkyl and / or alkenyl oligoglycosides, fatty acid monoglyceride sulfates and polyols and the use of such mixtures for the preparation of the preparations.
- Shaving creams are mostly sold in tubes. In the application, one presses a little cream onto a moistened shaving brush and then soaped the body parts to be shaved.
- Conventional shaving creams have the disadvantage of cementing at temperatures above room temperature, as occurs, for example, in summer or in hot countries. This lack of deformability, for example, makes it no longer possible to apply it from a tube.
- EP-Bl 0 070 074 discloses foaming surfactant mixtures which, in addition to alkyl oligoglucosides, contain anionic surfactants with sulfate, sulfonate or carboxylate groups. The mixtures form stable foams and are suitable, for example, for shaving creams.
- Japanese patent application JP 91/131 680 (Kao) relates to foaming compositions containing alkyl oligoglycosides and a blowing agent; reference is made to the use of this mixture in shaving foams.
- alkyl oligoglucosides are known to be extremely skin-friendly, for use in soap-free shaving creams, however, neither the foaming power is sufficient nor the deformability at higher storage temperatures.
- the foam formation can be increased, but the dermatological compatibility of the preparations sig ⁇ decreases significant from; in addition, these mixtures also show no satisfactory deformability.
- the object of the present invention was therefore to develop mild, pH-neutral aqueous shaving preparations which are distinguished both by improved deformability at temperatures up to 45 ° C. and by advantageous foaming power.
- these preparations should be homogeneous, have a good consistency and an attractive gloss.
- the invention relates to mild aqueous shaving preparations containing
- the surfactants in the preparations according to the invention are synergistically enhanced with regard to their foaming power and their skin-cosmetic tolerance.
- the proportion of alkyl and / or alkenyl oligoglycosides, fatty acid monoglyceride sulfates and polyols according to the invention also ensures that there are no undesirably high viscosities in the preparation of the shaving creams and that production is possible with the aid of simple stirrers; homogenization as an additional processing step can therefore be dispensed with.
- the preparations cannot be cemented even at temperatures above 30 to 40 ° C. and can easily be deformed, so that, for example, application from a tube is easily possible.
- the agents according to the invention are pH-neutral, homogeneous, have a nice gloss and a particularly creamy consistency.
- shaving preparations which contain components a) to c) in the following amounts have proven to be optimal:
- Alkyl and alkenyl oligoglycosides are known substances which can be obtained by the relevant processes in preparative organic chemistry. Representative of the extensive literature, reference is made here to the publications EP-Al-0 301 298 and WO 90/3977. The alkyl and / or alkenyl oligoglycosides follow the formula (I)
- R 1 stands for alkyl and / or alkenyl residues with 6 to 22 carbon atoms
- G for a sugar residue with 5 or 6 carbon atoms
- p for numbers from 1 to 10.
- the alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose.
- the preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides.
- the alkyl or alkenyl radical R 1 can be derived from primary alcohols having 6 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxo synthesis.
- the alkyl or alkenyl radical R ⁇ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, and the like technical mixtures which can be obtained as described above. Alkyl oligoglucosides based on hydrogenated Ci2 / 14 ⁇ ⁇ ° kosalcohol with a DP of 1 to 3 are preferred.
- Fatty acid monoglyceride sulfates are also known substances which can be obtained by the relevant methods of preparative organic chemistry.
- a preferred method for their production is to sulfate monoglycerides or triglyceride / glycerol mixtures with gaseous sulfur trioxide [WO 92/09 569, WO 92/09 570 (Henkel)].
- Fatty acid monoglyceride sulfates which are suitable as component b) in the sense of the invention follow the formula (II),
- R ⁇ CO represents an aliphatic acyl radical having 6 to 22 carbon atoms and 0 and / or 1 to 3 double bonds and X represents alkali metal and / or alkaline earth metal, ammonium, alkylammonium or alkanolammonium.
- Fatty acid monoglyceride sulfates are preferably used, the fatty acid components of which are derived from coconut oil and have 12 to 18, preferably 12 to 14, carbon atoms. Due to the manufacturing process, the monoglyceride sulfate can also contain small amounts of disulfate.
- the preferred counterion X is sodium, ammonium or magnesium.
- polyols 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.
- Propylene glycols and glycerol alone or mixtures of these polyols with sorbitol and / or butylene glycol are preferred.
- Glycerol is preferably used as the polyol component which keeps the shaving preparations moist.
- the shaving preparations according to the invention can also contain other customary auxiliaries and additives.
- auxiliaries and additives include perfume oils, superfatting agents such as cetyl alcohol, lanolin, stearyl alcohol, lecithin, isopropyl myristate, vase line 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 shaving preparations can be protected against microbial spoilage by adding microbicidal substances.
- the proportion of optional auxiliaries and additives in the preparations can be 0.5 to 10% by weight; the proportion of components a) to c) is reduced accordingly. All percentage ranges are understood with the proviso that they add up to 100% by weight.
- the shaving preparations according to the invention are produced, for example, by placing the surfactant ingredients as concentrates or aqueous solutions in a mixing container, heating with stirring and metering in the polyol and, if appropriate, other ingredients and the remaining water in portions.
- the active substance content of the preparations can be 60 to 85, preferably 70 to 80% by weight.
- aqueous shaving preparations according to the invention are pH-neutral, foam-strong, deformable even at higher storage temperatures and have a particularly high level of skin-cosmetic compatibility. They can also be produced and filled without viscosity problems.
- Another object of the invention therefore relates to the use of mixtures containing
- Ci2 / 14 coconut mono 9 1 y l ceridsu fat Natri ⁇ sa l z Fa - Henkel KGaA, Dusseldorf / FRG; 50% by weight aqueous paste.
- Shaving creams were produced in the following manner in accordance with the compositions given in Table 1:
- the ingredients of the formulations Rl to R4 and R7 were homogeneously mixed in the order given at room temperature with stirring.
- the fatty acids were placed in a container and heated to 80 ° C.
- Glycerin and, if appropriate, sodium or potassium hydroxide solution were added in portions, with stirring, the mass becoming homogeneous. After adding the remaining water, the mixture was allowed to cool and the perfume oil was metered in.
- the creams Rl to R4 according to the invention had significantly better skin cosmetic tolerance than the comparative formulations R5 to R7; and *** The creams R1 to R4 according to the invention were still easily deformable even at 45 ° C., while the comparative formulas R5 to R7 had set in cement-like form even at significantly lower temperatures (see Table 3). Easily deformable is understood to mean that a shaving cream can easily be pressed out of a tube by hand.
- Tab. 1 Composition of the shaving preparations in% by weight
- the foaming power of the recipes was determined using the whipped foam method according to DIN 53 902, Part B.
- the results on base foam and foam disintegration are summarized in Table 2.
