Definitions

  • Liquid products for example cosmetic products
  • preservatives are added to these products.
  • concerns have recently been raised against preservatives because of their possible toxic and allergenic potential.
  • the operational requirements for this are associated with very high hygiene requirements, which leads to high investment and maintenance costs.
  • the object was therefore to provide liquid products which are protected from spoilage and which are preferably free of preservatives in the ready-to-use product or contain only a small amount of preservatives and which can be produced inexpensively and with generally customary production facilities.
  • the usual spoilage-causing microorganisms are not viable in a strongly acidic (component A) or strongly alkaline environment (component B).
  • component A strongly acidic
  • component B strongly alkaline environment
  • the individual components of the product according to the invention are therefore very well preserved, even without the addition of preservatives or when only a small amount of preservatives are used.
  • the product according to the invention preferably contains no preservatives.
  • Components A or B are adjusted to be strongly acidic or strongly alkaline to the extent required by the different ingredients, so that adequate preservation is ensured.
  • Component A can preferably have a pH of 0 to 2 and in particular a pH of 0 to 1, while the pH of component B is preferably 11 to 12.
  • the acidity of component A is so stoichiometrically related to the alkalinity of component B that after mixing the product according to the invention is obtained with the pH value desired for the particular purpose.
  • the pH value of the ready-to-use ready-to-use liquid product can be in the range from 2.5 to 9, preferably 3 to 7, for example.
  • the product according to the invention can be used in many areas, for example as a pharmaceutical, food or cosmetic.
  • the use of the products as a cosmetic has proven to be particularly advantageous, for example hair or body cleansing agents, hair care products, hair setting agents and hair tinting agents.
  • organic or inorganic acids alone or in a mixture with one another, for example hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, propionic acid, lactic acid or citric acid, can be used, with phosphoric acid and citric acid being preferred, while organic or inorganic bases, for example alkali metal hydroxides such as sodium hydroxide or ammonia and their derivatives, such as monoethanolamine, are suitable for adjusting the alkaline pH of component B.
  • organic or inorganic bases for example alkali metal hydroxides such as sodium hydroxide or ammonia and their derivatives, such as monoethanolamine
  • the acids and bases used for acidification or alkalization when used in small amounts, are common ingredients for cosmetics, which after mixing components A and B neutralize each other for the most part, depending on the desired pH, and as physiologically acceptable salt are present which, in contrast to the preservatives normally used, has no allergy-triggering potential.
  • components A and B can be thin.
  • components A and / or B can contain viscosity-increasing ingredients which, preferably by chemical reaction, for example salt formation, ensure an increase in the viscosity after mixing.
  • An example of a suitable, thickening and physiologically acceptable salt is sodium chloride, which can be formed, for example, from hydrochloric acid and sodium hydroxide solution.
  • Both components A and B can also be colored differently in order to obtain the desired mixed color after the components have been combined.
  • a change in color after mixing can also be achieved by using pH-dependent dyes, a change in color resulting from the change in pH. This color change can be used as an indicator of the optical control for the correct mixing.
  • Food Green 3 (C.I. 42053) may be mentioned as an example of a suitable dye, the color changing from violet to turquoise as a result of the pH change.
  • components A and / or B can be appropriately buffered, for example with glycine, phosphate, citrate or other usual buffers, which are selected depending on the desired pH range.
  • the product according to the invention can be such that one of components A or B is liquid, while the other component is in solid form.
  • the application therefore also relates to a liquid product which is protected from spoilage and which is in the form of two components A and B which, after mixing, give the ready-to-use product, characterized in that component A is liquid and has a pH of 0 to 3 and component B is solid and contains a base, or component B is liquid and has a pH of 10 to 14 and component A is solid and contains an acid.
  • the solid component can be present, for example, as powder, granules or in tablet form.
  • Citric acid may be mentioned as an example of an acid suitable as a solid component, while sodium hydroxide can be used as a suitable solid base, for example.
  • the liquid product being provided in the form of two separate components A and B and the components being mixed before use to give the ready-to-use product, characterized in that component A has a pH of 0 to 3 and component B to a pH of 10 to 14.
  • the two components can be filled, for example, in a 2-chamber container, which is constructed in such a way that components A and B mix independently when they are opened for the first time, for example according to DE-GM 89 00 291 or DE-PS 36 31 135 .
  • the metering can be carried out, for example, by a portioner on the container, by volume measurement using measuring cylinders, burette-like devices or metering pumps.
  • the two-chamber container was developed especially for the end consumer, the latter two containers are suitable for professional use by a specialist, for example a hairdresser or manufacturer.
  • Component A is a compound having Component A:
  • Component A is low viscosity (low viscosity) and has a pH of 0.5.
  • Component B is a compound having Component B:
  • sodium lauryl ether sulfate 28 percent aqueous solution 0.40 g perfume 0.10 g of solubilizer 24.28 g of water (fully desalinated) 0.22 g of sodium hydroxide
  • Component B is thin (low viscosity) and has a pH of 11.5.
  • Component A is filled into the lower part of a 2-chamber container via a filling system which is customary in the cosmetics industry, for example with the aid of a piston metering device.
  • component B is also poured into the upper part, for example with the aid of a piston metering device, and finally the two-chamber container is closed with a closure.
  • components A and B are mixed with the container closed by pressing out the intermediate stopper using a pestle.
  • neutralization to the desired pH with simultaneous increase in viscosity occurs by gentle shaking, and the ready-to-use hair shampoo is obtained, which is free from preservatives and which was nevertheless protected against microbiological influences.
  • the hair shampoo thus obtained has a pH of 5.2 and a viscosity of 1000 mPa s.
  • Example 2 Course flushing
  • Component A is a compound having Component A:
  • Component A is thin and has a pH of 1.2.
  • Component B is a compound having Component B:
  • Component B has a viscosity of 2500 mPa s and a pH of 11.4.
  • the 2-component preparation is produced analogously to Example 1.
  • the 2-component preparation is protected against microbiological influences and, after mixing, has a pH of 3.3 at a viscosity of 600 mPa s.
  • the viscosities were determined in each case using a Haake viscous scale with rod II and a coating weight of 10 g at 30 degrees Celsius.
