Description

[0001] The invention relates to a carrier material-soap body comprising a soap incorporated into a carrier material.

[0002] Furthermore, the invention relates to a corresponding manufacturing method and a corresponding use.

[0003] The current state of the art shows a number of solutions for film-wrapped detergents or dishwashing detergents consisting of preferably biodegradable, water-soluble plastics. While these do not contribute to microplastic pollution in wastewater, they can be problematic in households with small children, for example, as film-wrapped detergents often resemble teething rings ("Detergent Pods and Liquid Caps: Can Microplastics Be Produced?", Consumer Advice Center North Rhine-Westphalia, November 24, 2022).

[0004] The well-known detergent or cleaning agent dispensing systems or capsules today mostly consist of at least two-part systems with different components.

[0005] EP 2 069 471 B2 discloses a detergent or cleaning agent delivery system for polymer-containing molded bodies that are strip-shaped, sheet-shaped, disc-shaped, layered, plate-shaped, or web-shaped, as well as its use for the individual dosing of non-liquid detergents or cleaning agents. Furthermore, the invention relates to a method for producing an aqueous system with cleaning properties and a method for the local stain treatment of substrates.

[0006] Furthermore, document EP 1 660 023 B1 discloses cosmetic and dermatological preparations in the form of capsules comprising a capsule shell that is solid, semi-solid, and / or dimensionally stable and consists essentially of waxes, emulsifiers, natural and / or synthetic polymers, and / or mixtures thereof, as well as the process for their production. Furthermore, the invention encompasses a capsule with a filling consisting of one or more solid, semi-solid, pasty, and / or liquid ingredients. Optionally, the shell can additionally contain water and / or polyols.

[0007] Soaps for personal hygiene are available in liquid and solid forms. Solid soaps, which are as sustainable as possible, contain natural ingredients and are readily biodegradable.

[0008] The problems with the state of the art are essentially that currently known products that contain metered detergents or dishwashing detergents in wrappers or portioned tablets use wrappers containing plastics or plastic components that are not completely and sustainably degradable.

[0009] In addition, these systems are usually not easy to manufacture or contain active ingredients that may be harmful to humans.

[0010] Solid soaps for cleaning hands, for example, often contain active ingredients that may be harmful to humans, such as various fragrances, parabens or polyethylene glycol, and are not entirely ecologically sustainable.

[0011] In addition, when using soap, more soap is usually used than is actually necessary, which is also considered a disadvantage.

[0012] It is also the case that there is still no “soap to go” available on the market that is easy to carry and can be individually portioned without separate foil packaging.

[0013] The present invention is based on the object of improving existing systems both in the field of ecologically sustainable packaging of detergents or dishwashing detergents and in the field of personal hygiene for people outdoors and on the go by providing an ecologically sustainable system that is easy to produce and use and is also free of potentially harmful active ingredients for humans.

[0014] This object is achieved with a carrier material-soap body comprising a soap incorporated into a carrier material, characterized in that - the carrier material is a pectin; - the body is designed as a solid material or as a hollow material, whereby the body as a hollow material serves as an inclusion material for hygroscopic media; - the body is solid at ambient temperature; - the body is malleable when moistened and / or heated and - the body is water-soluble.

[0015] The weight ratio of pectin to soap in the body may in particular be between 1:1 and 4:1 and / or between 2:1 and 3:1 and / or 2.3:1.

[0016] Hygroscopic media may include dishwashing powder and / or washing machine powder.

[0017] The body shape can also preferably be designed in a variable manner. For example, the body made of solid material can be plate-shaped, while a body made of hollow material can be spherical or UFO-shaped.

[0018] In particular, the body is constructed in such a way that the soap is predominantly located in the spaces of the polysaccharide structure of the pectin.

[0019] In a preferred embodiment, the pectin can be formed as pectin from rose hips and / or pectin from apples and / or the soap can be formed containing surfactants from sunflower oil and / or rapeseed oil.

[0020] The process for producing a carrier material soap body comprises at least the following steps: A. Weighing water and heating until boiling; B. Weighing pectin powder; C. Stir pectin powder into the water and bring to a boil; D. Weighing soap powder; E. Stirring soap powder into the pectin-containing water to form a pectin mass; F1. Filling the pectin mass into a negative mold and drying or F2. Pouring the pectin mass onto surfaces and drying, followed by shaping by moistening and / or heating and deep drawing over a negative mold.

[0021] Drying can be carried out particularly under ambient conditions.

[0022] In addition, the body can be produced as a hollow material by punching and / or welding formed complementary positive shapes together and / or the cavity in bodies as a hollow material can be at least partially filled with hygroscopic media.

[0023] The carrier material-soap body can preferably be used as hand soap and / or body soap and / or hair soap and / or packaging material for hygroscopic media.

[0024] By constructing the body in such a way that the soap is predominantly located in the interstices of the pectin's polysaccharide structure, a carrier material-soap body with the desired material properties is achieved. The soap in the interstices makes the pectin's polysaccharide structure flexible. The result is a solid product that is moldable by heating and / or moistening and is simultaneously water-soluble.

[0025] For example, when used as packaging for detergent, the carrier material dissolves when used in the washing machine, allowing the detergent to take effect. Any residue left over can be reused, for example, as hand soap.

[0026] When the soap body carrier material is used as packaging, time-consuming unpacking processes for individual portions of detergent or dishwashing detergent are eliminated.

[0027] It allows for easy handling as the packaging does not have to be removed from the hygroscopic medium.

[0028] The soap body is ecologically sustainable and made from plastic-free materials.

[0029] If the soap base is manufactured from a solid material, for example, in a platelet shape, it can be used as hand soap, especially for use on the go or outdoors. The soap plates can be easily carried in a dispenser, preferably with a dispensing mechanism. This eliminates the time-consuming unpacking process for individual soap portions and enables easy handling.

[0030] In addition, when the carrier material soap body is used as soap, carbon dioxide emissions are reduced due to the lower weight compared to liquid soap and the lack of water content during transport.

[0031] Furthermore, the soap does not contain fragrances such as lyral, hydroxycitronellal and cinnamyl alcohol, nor parabens or polyethylene glycols, which can potentially trigger fragrance allergies in humans.

[0032] In addition, the tablets can be specifically labeled with the required amount of soap product for a single handwashing session. Since the user washes their hands until the tablet completely dissolves, this encourages and motivates the user to wash their hands for longer and thus improve hand hygiene.

[0033] Compared to liquid soap, tons of PET packaging and other plastics in the form of soap dispensers and other containers can be saved.

[0034] The soap base is a sustainable product. The pectin carrier material is completely biodegradable and water-soluble, and the soap itself can also be made from ecologically sustainable raw materials such as sunflower oil and rapeseed oil.

[0035] The invention is described below with reference to the accompanying figures in the description of the figures, which are intended to illustrate the invention and are not to be considered limiting. They show: Fig. an exemplary photographic representation of a first embodiment of a carrier material soap body according to the invention; Fig. an exemplary schematic representation of a second embodiment of a carrier material soap body according to the invention ( Fig. ) and Fig. an exemplary photographic representation of the individual process steps of the manufacturing process of the carrier material soap body according to the invention from Fig. ( Fig. ).

[0036] Fig. shows a photographic representation of a first embodiment of a carrier material-soap body according to the invention. In this embodiment, the carrier material-soap body is formed as a solid material in the form of a round platelet with a branding. The platelet shape with branding was obtained by pouring the liquid pectin mass into a negative mold and subsequently drying it in air.

[0037] In Fig. An exemplary schematic representation of a second embodiment of a carrier material-soap body according to the invention is shown. In this embodiment, the carrier material-soap body is depicted as a hollow material in the form of a UFO-shaped capsule. For production, two positive molds obtained by deep drawing were punched and welded. Before welding, it is possible to fill the body with hygroscopic media such as dishwashing or washing machine powder, and to use the body according to the invention as a sustainable, water-soluble packaging material. Fig. shows the carrier material soap body in perspective view and Fig. in a top view with exemplary sizes.

[0038] Fig. shows an exemplary photographic representation of the individual process steps a) to h) of the manufacturing process of the carrier material soap body according to the invention from Fig. In process step 3a), a weighed amount of water is heated to boiling. Fig. This shows the weighing of pectin powder. In process step 3c), the pectin powder is stirred into boiling water and brought to a boil. In the subsequent process step 3d), soap powder is weighed in. Fig. shows the stirring of soap powder into pectin-containing water to form a pectin mass. In process step 3f), the pectin mass is filled into negative molds. Subsequently, in process step 3g), the negative molds are dried in the air at ambient conditions. Fig. After drying, the platelets are displayed for a period of 24 to 48 hours. After drying, the platelets are removed from the molds and are ready for use. Alternatively, the produced pectin mass can be poured onto surfaces and dried. The molding is then carried out by moistening and / or heating and deep drawing using negative molds.

[0039] In this example, 150 g of water, 7 g of pectin and 3 g of soap are used. QUOTES CONTAINED IN THE DESCRIPTION
