Definitions

  • the present invention relates to a soap composition and a soap stick based on the soap composition.
  • Toilet soap is mainly used in the form of bar soap. In use, this is first wetted with water or brought into contact with the skin wetted with water or with a wash cloth wetted with water until the soap has detached as much as for the
  • the soap bar itself is wet and covered with a greasy layer of loosened soap.
  • the wet soap bar tends to swell or so-called swamp and then offers an unaesthetic sight.
  • the wet soap In order to prevent contamination of the sink edge or the bathroom furnishings with detached soap, the wet soap must be kept in specially designed soap dishes or soap holders. Carrying wet, softened or swollen bars of soap is a well-known problem, especially when traveling.
  • the use of paste-like soaps from dispensers or liquid soaps from special pump dispensers are known alternatives to the use of bar soap. These pasty or liquid preparations can be spread on the skin without the simultaneous use of water. With the known, bar-shaped soaps, however, the skin cannot be soaped satisfactorily without the simultaneous exposure to water.
  • the aim of the present invention is to provide a shaped toilet soap composition which is suitable for soaping the skin without simultaneous exposure to water and which itself remains dry.
  • the soap remaining on the skin should then produce a voluminous, fine-bubble foam with water under the usual washing conditions and enable a satisfactory cleaning result.
  • Another object of the invention is to provide a suitable assembly for such a soap composition in the form of a pencil soap.
  • Pencil soaps are already known as prewash agents for treating heavily soiled areas in textiles.
  • compositions known from DE-PS 2 132035 are not suitable for achieving the objects of the invention, since sufficient soap rubbing off on dry skin can neither be achieved nor is sufficient foam formed during washing.
  • a soap composition which is characterized by a content of: (A) 20-40% by weight of alkali soap of C 12 -C 18 fatty acids with a content of at least 40% by weight of lauric and / or myristic acid
  • the soap composition according to the invention has a consistency which is sufficiently firm for the shaping and is therefore suitable for confectioning as pencil soap.
  • a fine soap film remains on the skin, which results in a rich, fine-bubble foam when subsequently washed with water.
  • the soap mass itself does not come into contact with the water in this application, so it remains dry and maintains a satisfactory appearance.
  • Both sodium and potassium soap can be used as the alkali soap. However, sodium soap or a mixture thereof with a predominant proportion of sodium soap is preferably suitable.
  • a fatty acid or a fatty acid mixture based on C 12 -C 18 fatty acids is suitable for the production of the soap.
  • Such fatty acids can be obtained, for example, from coconut oil, palm kernel oil or babassu oil by saponification or cleavage and separation of the shorter-chain portions.
  • Such C 12 -C 18 fatty acid fractions contain approx. 50 -
  • the C 12 -C 18 fatty acid mixture used has a content of at least 40% by weight of lauric and / or myristic acid.
  • the alkali soaps of the C 12 -C 18 fraction of a coconut oil or palm kernel oil fatty acid are preferably used. Of this fraction, the sodium soap is preferably used in an amount of 25-35% by weight.
  • polyhydric alcohols with 2 to 4 carbon atoms examples include ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,2-butanediol, 1,4-butanediol, glycerol and mixtures of these alcohols.
  • diethylene glycol all higher polyethylene glycol ethers up to an average molecular weight of approximately 10,000 can be used as polyethylene glycols; preference is given to using polyethylene glycols up to an average molecular weight of 700.
  • the preferred amounts of the polyhydric alcohols and / or the polyethylene glycols also depend on the type of polyols or polyethylene glycols used.
  • 1,2-propylene glycol amounts of 30-40% by weight of this alcohol are particularly preferred for the soap compositions according to the invention.
  • glycerin amounts of 25-35% by weight are sufficient to achieve soap masses of the desired consistency.
  • polyethylene glycols amounts of 15-30% by weight are generally sufficient, the higher molecular weight products preferably being used in the lower concentration range.
  • the shaped soap compositions according to the invention can also be prepared by mixtures of different polyhydric alcohols and polyethylene glycols.
  • 1,2-propylene glycol and / or glycerol are preferably used alone or predominantly as component (B) for the preparation of the soap compositions according to the invention.
  • skin cosmetic active ingredients for example skin moisturizers, proteins, superfatting agents (for example cosmetic oils, free fatty acids) can be deodorising, antimicrobial, complexing, antioxidative, rancidity-preventing, lime soap-dispersing and foam-improving additives in the soaps according to the invention be included.
  • Free, ie unsaponified, fatty acids are also suitable as superfatting agents, which remain in the soap mass due to saponification of the C 12 -C 18 fatty acids with substoichiometric amounts of alkali.
  • alkyl ether sulfates and / or fatty acid alkanolamides have a particularly favorable effect on the foaming behavior.
  • the alkyl ether sulfates have a lime soap dispersing effect and thus improve the foaming behavior and the foam resistance, especially in hard water.
  • Fatty acid alkanolamides are strong foam boosters, they increase the stability of the foam against fat and dirt.
  • Suitable alkyl ether sulfates are e.g. the alkali or alkanolammonium salts of sulfuric acid semiesters of the adducts of 1-10 moles of ethylene oxide with linear or predominantly linear alcohols with 10-18 carbon atoms.
  • Particularly suitable alkyl ether sulfates are the sodium salts of the linear, primary
  • Suitable fatty acid alkanolamides are the monoethanol amides and diethanolamides of C 12 -C 1 8 fatty acids such as coconut fatty acid fractions, palm kernel oil fatty acid fractions, tallow fatty acids hydrogenated tallow fatty acids, vegetable fatty acids such as palm oil fatty acid, soybean oil fatty acid, sunflower oil fatty acid or mixtures of said fatty acids.
  • coconut fatty acid monoethanolamide and coconut fatty acid diethanolamide are particularly suitable.
  • the soap compositions according to the invention preferably contain 1-8% by weight of an alkyl ether sulfate and / or 1-8% by weight of a fatty acid alkanolamide.
  • the water content of the soap compositions according to the invention is in each case the difference between the sum of the components mentioned and 100%. However, it is usually above 10% by weight and can be up to approximately 50% by weight.
  • the soap compositions according to the invention can be brought into any suitable bar soap form and used in this form. Because of the increased abrasion, however, it is particularly desirable if an area of the soap bar intended for gripping remains covered with a protective cover during use. This can be achieved according to the invention by using the soap compositions for the production of pencil soaps which are covered in the lower area with a covering made of an impermeable material. If necessary, this can be a fixed sleeve, which is provided with a clip-on or screw-on cap, so that the soap is completely covered after use.
  • the soap composition is particularly advantageous to use to produce a pencil soap which is arranged in a sleeve with a movable base and can be pushed out of the sleeve by means of a pushing or rotating mechanism.
  • Such pen arrangements are used, for example, for deodorant sticks, antiperspirant sticks and lipsticks.
  • the soap compositions according to the invention are prepared in a simple manner by mixing the components at a temperature above 60 ° C.
  • the mixture is allowed to cool to 50-55 ° C. with stirring without additional cooling, and the perfume oil is added at this temperature. After a few minutes of stirring, the still liquid soap mass is poured into the application tubes, e.g. filled in pen sleeves with push and twist mechanism. The soap mass solidifies there in a few hours.
  • coconut fatty acid C 12 -C 18 (Edenor (R) K 12-18) was heated to 65 ° C in a stirred tank with reflux cooling.
  • the polyhydric alcohols - 1,2-propylene glycol, glycerin or polyethylene glycol - were heated to 65 ° C in a second container, water, alkali hydroxide and the additives were dissolved therein. This solution was then added to the fatty acid with stirring and the mixture was stirred until the temperature had dropped to 50 ° C. At this temperature, the perfume oil was added and stirred in homogeneously.
  • the amounts in the table are percentages by weight.
  • a suitable measure for assessing the special usage properties of the soap composition according to the invention, in particular the required abrasion properties on the one hand and the strength and dimensional stability on the other hand is the consistency.
  • the hardness is measured using a test device such as that used to measure the Shore hardness of elastomers.
  • the principle of the measurement is that a cylindrical test mandrel of 15 mm in diameter with a conical tip (86 °) at a constant speed of 100 mm / min in a test specimen lying on a fixed test table made of the soap mass with planner
  • the penetration depths determined in this way are 1-6 mm (20 ° C); preferably suitable soap compositions have a consistency which corresponds to a penetration depth of 2-5 mm (20 ° C.) under the conditions mentioned.
