Definitions

• the present invention relates to a cleaning formulation, more particularly, an acid cleaning formulation comprising natural extracts which do not present a risk to the health of users or to the environment.
• the present invention therefore pertains to the sector of the chemical industry and, particularly, to the cleaning and disinfection product industry.
• Said formulation comprises non-ionic or amphoteric surfactants and a series of additives conferring an acid nature to said formulation.
• cleaner compositions used in various industrial and domestic fields comprise chemical substances that are toxic to the health of the user, causing eye lesions and skin irritations. This combined with society's growing interest in respecting the environment and sustainability has led to industries manufacturing compositions for cleaning different types of materials face the need to develop biodegradable chemical products in order to eliminate any generation of chemical waste so as to have zero impact on the ecosystem.
• patent CN103608445A describes a biodegradable cleaning composition comprising biodegradable abrasive particles.
• patent application WO2010147485A1 relates to an acid cleaning composition using at least three organic acids which, when combined, act to provide a strong cleaning activity and require less acid concentration to achieve the same degree of cleaning effect as existing cleaning compositions.
• compositions of the 3 mentioned patent documents are biodegradable
• the first two documents describe compositions comprising abrasive nanoparticles or particles.
• the last document mentioned describes a composition which must comprise a minimum of 3 acids in its composition.
• compositions that have a more ecological profile, in other words, that use more ecological ingredients, reduce the number of ingredients, reduce the application quantity necessary to achieve proper cleaning and are more effective than the current compositions.
• said compositions must be free of hazards for users and show proven efficacies that are equal to or better than other products currently existing on the market.
• the present document describes an improved cleaner formulation with respect to the cleaning compositions used at present in the detergent and cleaning product industry having very advantageous characteristics.
• Said formulation comprises natural extracts which do not present risks to health or to the environment and are biodegradable.
• the present document refers to the object of the present invention as an acid cleaning formulation or acid cleaner formulation interchangeably.
• the cleaning capacity of the products is mainly achieved by an optimal mixture of surfactants, solvents, citric acid, perfumes and colourants, all in an aqueous base.
• the present formulation is characterised by having an acid pH comprised between 2.5 and 6.5.
• the acid cleaner formulation object of the invention is characterised in that it comprises citric acid in a quantity of less than 5 %.
• Citric acid is a natural antioxidant that is present in most fruits and primarily in orange and lemon.
• citric acid is a very good preservative and has an excellent ecological and toxicological profile.
• the acid cleaner formulation object of the invention is characterised in that it comprises 0.1 % - 0.3 % of 99 % triethanolamine, which is a weak base acting as a pH regulator with an excellent toxicological profile, which allows the pH to be kept slightly above 2.5.
• the quantity of 99 % triethanolamine is comprised between 0.15 % and 0.3 % by weight with respect to the total weight of the formulation.
• the acid comprised in the formulation object of the present invention is controlled and stabilised by 99 % triethanolamine.
• the pH of the acid cleaner formulation cannot reach values below 2.5, preventing said acid cleaner formulation from being corrosive.
