Belgi a-Belgien (BE) (7I +) Oy Kolster Ab (5I +) Liquid detergent composition - Flytande tvattmedelskomposition

The present invention relates to a liquid, clear, aqueous detergent composition comprising a surfactant detergent, a protein derivative and common additives. More specifically, it relates to a liquid, clear, aqueous detergent preparation intended in particular for the cleaning of glassware, porcelain and glazed or translucent objects, where it provides excellent drainage properties, eliminating the need for towel drying and substantially reducing the amount of washed, rinsed and rinsed. and spotting.

The consumer evaluates the effectiveness of a detergent product in cleaning glasses, dishes, windows and other objects with a glossy surface on the basis of brightness, unworthiness, staining and streak-freeness. Liquid dishwashing preparations currently on the market are primarily intended to remove dirt from said glasses, dishes and windows, but detergent solution and reprecipitated dirt residues must be removed from the washed dishes by rinsing and / or wiping while still wet. If they are not rinsed and dried with a towel immediately, these residues dry on the surfaces of the washed dishes, leaving 571 27 spots, films or streaks that are difficult to remove.

If the dishes are washed and / or rinsed in ordinary water and not dried immediately with a towel, spots due to the hardness of the water will also appear on the washed and rinsed surfaces as the water evaporates.

Drying washed items, such as glasses and dishes, immediately after removing them from the washing and rinsing fluids is uneconomical (more towels are needed) and is not always possible (interrupting washing too often). Because of this, many housewives simply set aside washed or washed and rinsed items to drain and air dry. Thus, the cleaning performance of the used product, which may have been visually accepted by the hostess at the end of the washing or rinsing cycle, is lost due to drying of the washing liquid or rinsing water, difficult to remove, unpleasant, sticky or reprecipitated residues of detergent, dirt and / or water.

Cleaning larger glossy surfaces, such as tile walls, e.g., in a shower room, lice ceramic bathtubs, sinks, or similar conduits with a glazed surface also requires wiping or rinsing and wiping while still wet to prevent the formation of spots, film, and streaks. Wiping immediately after cleaning to prevent evaporation and the resulting formation of spots, streaks and film is not always possible and requires frequent interruption of the cleaning process. Therefore, cleaning agents cannot be considered to clean well, although dirt may have been removed in the first step due to streaks, film, and spots left on the treated surfaces.

Attempts have been made to reduce the effect of precipitation of detergent, dirt and / or water hardness residues during air drying by using various additives either in the washing or rinsing step of the cleaning cycle, either by forming complexes with water hardening salts, by adding better dirt suspending agents or by forming special rinsing agents. Complexing and / or soil suspending agents incorporated into liquid detergent preparations create recipe formation difficulties, while special rinse aids must be packaged and used separately.

It has now surprisingly been found that by combining a small amount of gelatin with a gel strength of at least 25 Bloora grams, a molecular weight of at least 12,500 and an isoelectric point between pH U, 5 ~ 9.2, and a non-ionic surfactant detergent optionally containing other typical surfactants. active substances and / or carrier salts, excellent detergents and cleaning agents are obtained which are particularly suitable for washing glassware, porcelain and shiny or glazed objects which provide excellent drainage properties, make it unnecessary to towel dry, substantially reduce the number of washed, cleaned, formation of films, streaks or spots on rinsed and air-dried glass, porcelain and glossy or 3 57127 glazed articles.

Detergent preparations containing gelatin or hydrolyzed proteins and surfactant detergents are described, for example, in GB Patent 1,160-853, IT Patent 862,2U7 and DE Patent 1,929,0U0. The solutions or detergent compositions disclosed in said GB patent contain partially cleaved protein with a gel strength of zero Bloom grams. Gelatin with a gel strength of zero Bloom grams is completely unsuitable for the detergent composition of this invention. The gelatin in the detergent compositions mentioned in the IT-DE patent cannot be incorporated into the liquid detergent composition of the present invention because the surfactant detergent system and other predominant components impair flowability.

If there is a continuing need for detergents, especially dishwashing detergents to remove dirt and improve the final dry appearance, there is certainly a continuing need for a combination of compatible materials that simultaneously provides cleaning and improved final dry appearance with the need for towel drying or wiping. It is therefore an object of the present invention to provide a liquid, clear, stable, aqueous detergent preparation for glossy or vitrified articles having excellent cleaning performance and improved flowability after rinsing, thus avoiding staining of washed, rinsed and air-dried glossy or vitrified surfaces, which in turn towel drying or rubbing unnecessary.

The attractiveness, efficacy and economy of the preparation of this invention can be - and this is another valuable feature of the invention - improved, adapted and adapted to special requirements by mixing with other water-soluble, organic, anionic surfactants, water-soluble organic acids or their salts, emulsifiers; bacterial toxins; coloring agents; fragrances; corrosion inhibitors; dirt suspending agents, which are described in more detail below.

"The liquid detergent composition of the present invention is characterized in that it contains, based on the total amount of the composition: (A) about 2 to about 1% by weight of a water-soluble, organic, nonionic surfactant which is (1) a tertiary oxide having the formula R 1 R 2 R 3 Y-> O (I) wherein R 1 is a straight-chain or branched, saturated or unsaturated aliphatic hydrocarbon, hydroxyhydrocarbon or alkyloxy hydrocarbon group having a total of 8 to 2 carbon atoms, R 1 and R 2 represent methyl, ethyl, hydroxy- a methyl or hydroxyethyl group, and Y is n or P; 57127 (2) amide of formula

R 11 -CO-m) m_, (R 5 ° H) 3_m (II) wherein R 1 is a saturated or unsaturated aliphatic hydrocarbon group having 7 to 21 carbon atoms; R 1 is a methylene or ethylene group; and m is 1, 2 or 3; (3) a condensation product formed of about 3 to 25 moles of ethylene oxide and one mole of an organic hydrophobic compound having an aliphatic or alkyl aromatic nature and having about 8 to 2 carbon atoms; or a mixture thereof; (B) about 0.1 to 5 parts by weight of water-soluble gelatin having a molecular weight of at least 12,500, a gel strength of between 25 ~ 300 Bloom grams and an isoelectric point between pH 1 », 5 ~ 9» 2; the rest being water.

The nonionic surfactants, gelatin and other components that can be used to form the liquid detergent composition of this invention are described below. When referring to a salt in the description of other surfactants and components, it is meant either a sodium, potassium, ammonium, trimethyl, triethyl, dimethyl, diethyl, trimethanol, triethanol, dimethanol or diethanolammonium salt, unless otherwise stated.

Because gelatin is a typical protein (obtained from collagen by boiling skin, connective tissue, bones, etc. with water), gelatin molecules, like the molecules of other proteins, are large and complex with an average molecular weight ranging from about 5,000 to 20,000 and above. Gelatin molecules which are charged in alkaline or acidic solutions and are thus amphoteric in nature have a characteristic isoelectric point which depends mainly on the processing conditions used in the preparation. The isoelectric point of acid-treated gelatin is generally between pH 7 and 9 · The isoelectric point of alkali-treated gelatin is normally between pH U, 6-5 · Gelatins with an isoelectric point as low as pH U.5 and so on can also be obtained using special treatments. high than pH 9 »2 and by mixing gelatins with different isoelectric points, any gelatin mixture with an isoelectric point between pH U, 5-9.1 can be formed.

The amount of water-soluble gelatin to be included in the liquid detergent composition of this invention may range from 0.1 to about 5% by weight, and more preferably from 0.2 to about 2% by weight, based on the total weight of the composition. If a very low amount of 0.1 wt.% Is required to produce a just perceptible drainage effect, the highest amount is limited to about 5 wt.% Due to the requirements of the recipe. to obtain a liquid preparation which is still pourable and thus easy to handle, dissolve and use.

In order to achieve said overall cleaning effect, i.e. removal of dirt by simple washing and removal of residues due to dirt, surfactant and water hardness due to run-off after further rinsing, but without rubbing or drying or drying with a towel, the molecular weight of the water-soluble gelatin used in the liquid detergent preparation of this invention must exceed -80,000 and most preferably between 35,000 and 50,000 while the isoelectric point of the gelatin should be between pH U.5 ~ 9 »2, preferably pH 6 or above and most preferably between pH 7 ~ 9, while the gel strength of the gelatin used is be more than 25 Bloom grams, preferably more than 50 and most preferably between 80 and 200 Bloom grams (gel strength in Bloom grams or Bloom strength is the force in grams required to press a 12.7 mm diameter cylinder onto the free surface of such a gel, containing 6.67% gelatin and having a moisture content of 15 #, to force it k mm g Eelin in * ,, reference: British Standard, Method for Sampling and Testing Gelatins).

Because the detergent compositions of this invention are in liquid form, they may suitably contain stabilizers, such as certain hydrotropes and / or electrolytes, to promote phase stability. Commonly used hydrotropes include conventional lower alkylaryl sulfonates such as sodium and potassium toluenesulfonate, xylene sulfonate, benzenesulfonate and cumene sulfonate. Lower alkanol hydrotropes such as methanol, ethanol, propanol and butanol may also be used as hydrotropes in this invention, but are not preferred. Electrolyte salts, such as potassium chloride, may optionally be added to improve the phase stability of liquid detergent preparations. When using the hydrotropes and / or electrolytes described above, they generally comprise from about 1% to about 10% by weight of the total preparation.
