Definitions

• the present invention relates to liquid detergents for cleaning solid surfaces for universal or specific use.
• Cleaning Products scouring usually contain one or more substances abrasives, inorganic salts, surfactants and other additives and / or adjuvants, such as bleaches, stabilizers, complexing agents, dyes, perfumes, thickening agents, etc.
• the abrasive substances generally recommended are particles of powdery mineral matter of often irregular shape with a grain size average between 10 and 100 ⁇ m.
• Reducing the hardness and / or particle size of the abrasive particles largely helps to avoid or alleviate the problem of damage support, but it simultaneously affects product efficiency for cleaning, eg eradicating stuck grease or other residues dried from various origins.
• Japanese patent JP000204035 discloses a weakly acidic cleaning product for the skin which may optionally contain, inter alia, powdered polyethylene, the objective of adding powdered polyethylene being to improve the quantity and quality of the foam.
• the object of the present invention is therefore to provide products of general purpose cleaning liquids with scouring action, allowing elimination stubborn stains, eg burnt grease and smoke residue on solid supports, without scratching, scratching or tarnishing the treated surfaces.
• this objective is achieved by a liquid detergent to scouring action for cleaning solid surfaces containing water, or more surfactants and particulate polyethylene in suspension.
• polyethylene as an abrasive or scouring agent in detergents of the present invention makes it possible to significantly reduce the risk of scratching, scratch or tarnish the cleaned surfaces, while benefiting from high scouring.
• Another advantage highlighting the universal nature of the present detergents is that they are also suitable for cleaning heavily soiled textiles.
• the polyethylene used preferably consists of fine particles, with a average particle size in the range of 30 to 100 ⁇ m, preferably with a narrow particle size distribution. A more preferred range is between 40 and 80 ⁇ m, with a maximum particle size less than 150 ⁇ m.
• the abrasive agent i.e. particulate polyethylene
• Its content in detergents of this invention can be varied to a large extent and will depend on one hand on the intended use and on the other hand the expected storage period, i.e. the desired stability of the suspension.
• the abrasive agent generally represents less than 15% by weight, preferably from 0.1 to 10% by weight, or preferably from 1 to 5% by weight of the detergent composition of the present invention.
• supports for the polyethylene are not critical insofar as they facilitate or stabilize the polyethylene suspension and are compatible with other ingredients. These will generally be components with a simultaneous affinity for polyethylene and for the solvent, i.e. water, by example in general of the surfactants, described below, but in particular nonionic surfactants.
• a favorite group of carrier compounds for polyethylene are ether-type fatty alcohols alkylated polyethylene glycol, the content of which is preferably between 2 and 15% by weight.
• Surfactants within the meaning of the present invention may be anionic, cationic, nonionic and / or amphoteric surfactants. Content total of surfactants in the detergents of the present invention does not generally not more than 40% by weight and it is in particular between 0.1 and 30% by weight, preferably between 5 and 20% by weight.
• Suitable anionic agents include for example carboxylic acids, C 6 -C 22 and their salts, alkylbenzenesulfonic acids C 8 -C 20 and their salts, alkyl sulphates, C 6 -C 22 and alkylpolyoxyalkylènesulfates C 6 -C 22 with 1 to 20 units of oxyethylene and / or oxypropylene.
• Preferred anionic surfactants are C 6 -C 22 fatty acids, saturated or unsaturated, branched or not, as well as their salts, for example their alkali or alkaline earth metal salts, in particular sodium and potassium.
• Preferred fatty acids are oleic, palmitic, stearic acid, as well as their mixtures.
• the nonionic surfactants can be chosen from the group of C 6 -C 22 fatty alcohols or oxoalcohols and their adducts with ethylene oxide.
• liquid detergents according to the invention by incorporating one or more amphoteric and / or cationic surfactants therein.
• one or more organic co-solvents chosen from the group of alcohols, for example methanol, ethanol, propanol, etc., glycols, for example ethylene glycol, diethylene glycol, ethers, for example diethyl ether, dibutyl and / or glycol ethers, for example, mono-, di-, tri- or polyethylene glycol ether.
• a preferred co-solvent is butyldiglycol.
• the viscosity of the compositions of the present invention can be adjusted by according to needs.
• One or more thickening agents are there added, preferably before the introduction of the other ingredients.
• detergents can contain one or more other common additives and adjuvants.
• these are for example substances chosen from stabilizers to improve the qualities of the suspension, foam inhibitors, complexing agents to complex certain ions metallic, sequestrants to mitigate the effects of water hardness, preservatives for longer term protection the agents for bleaching such as sodium perborate, bactericidal agents or disinfection, anti-corrosion agents, anti-static agents, dyes, for example to allow the identification of the different desired uses, perfumes, etc.
• the pH of detergents can be adapted to requirements. Generally in such detergents, it is recommended to use sodium hydroxide to facilitate wetting and therefore the elimination, among other things, of grease on the surfaces which are not sensitive to basic pH. Sometimes, for example in the case of textiles it may be more appropriate to use potassium hydroxide which is less oxidizing for these applications.
• the pH insofar as it is not imposed by the chosen ingredients, can be adapted by adding an acid or a base, for example citric acid or sodium and / or potassium hydroxide.
• liquid detergents in this invention are not critical, as long as it is not necessary not by common sense. Indeed, for example the support compounds for the polyethylene will preferably be added before the latter to avoid a deposit premature particles.
• liquid detergents For the preparation of the liquid detergents according to the invention, it is practical to start with a minimum of 20% by weight of water, to which we add then the other ingredients one by one or in the form of partial premixes and the volume is finally adjusted with the remaining water.
