Abstract
The present invention relates to the use of sulphamic acid in a liquid acidic composition comprising another acid, for improved skin mildness.
Description
Invention field
The present invention relates to tart crust composition, particularly remove the composition of calcium dirt (limescale).
Background of invention
Comprise that strong acid and/or faintly acid are that the hard-surface cleaning composition of basal component is that prior art is known with acid.The composition of for example removing the calcium dirt mainly with strong acid and/weak acid is basal component.Yet the human consumer realizes that the composition of this removal calcium dirt belongs to the row of the detergent composition that stimulates most.In fact, many human consumers are when using this composition, and skin can be upset.
Particularly when using this tart composition, user's hand is upset easily.When composition used with pure state with dilute form, this all can take place.
It is believed that acid can corrode the superiors of epiderm skin, change the neutral pH of skin.This causes skin elasticity to reduce.It is more responsive that skin also can become, and the result makes xerosis cutis and coarse.This outer skin can be burnt, and reddens, pain and itch.
The objective of the invention is to improve acidic composition, particularly remove the mildness and the stimulation that reduce skin of the acidic composition of calcium dirt skin.Another object of the present invention provides the skin milder, and the acidity that has good removal calcium dirt performance is simultaneously removed calcium dirt composition.
The present invention has overcome above-mentioned these problems by use thionamic acid in being suitable for removing the liquid acidic composition of crust fouling.In fact, have now found that the gentle performance of the skin of said composition improves by known skin irritant acid for example being added thionamic acid in the liquid composition of toxilic acid comprising other.In fact, when user's skin contacted with said composition, the user felt less skin irritation.
Comprise thionamic acid to remove calcium dirt composition be that prior art is known.EP-A-666,305 disclose and comprise toxilic acid and remove calcium dirt composition as the acidity of second kind of acid of thionamic acid.EP-A-666,305 openly can not improve said composition to the mildness of skin and/or reduce the stimulation of said composition to skin when thionamic acid adds in the liquid acidic composition.
Summary of the invention
The present invention uses the mildness of thionamic acid improvement to skin in the liquid acidic composition that comprises another kind of acid.
Detailed Description Of The Invention
Necessary component of the present invention is a thionamic acid.Thionamic acid can add in the composition of the present invention with its sour form or as its an alkali metal salt.Therefore thionamic acid can for example add with sulfamate.Thionamic acid commercial by trade(brand)name Sulphamic acid from Albright﹠amp; Wilson or Nissan chemicals buy.
According to the present invention, said composition is included as the thionamic acid of total composition weight 0.1%-20%, preferred 0.1%-10%, more preferably 0.1%-5%.
The present composition is the tart composition.Therefore preferred they to be formulated into pH be 0.1 to 4.5, more preferably 0.1 to 3, most preferably 0.3 to 2.
The necessary component of another of the present composition is another kind of acid or their mixture." another kind of acid " here the meaning is any strong and/or weak organic or inorganic acid except said thionamic acid.Can use among the application and well known to a person skilled in the art any strong and weak acid.The present composition is used to remove the calcium dirt or comprises the dirt of calcium dirt as main component.Therefore the present composition comprises and removes calcium dirt mineral acid as said other acid, sulfonic acid for example, comprise alkylsulphonic acid such as methylsulfonic acid and aryl sulfonic acid such as Phenylsulfonic acid, toluenesulphonic acids or cumene sulfonic acid, and hydrochloric acid, nitric acid, phosphoric acid and sulfuric acid, or the organic acid that removes the calcium dirt for example toxilic acid or citric acid, or their mixture.
Particularly suitable to go the acid of calcium dirt be toxilic acid according to used in the present invention.Maleic anhydride is convenient to be used in the present composition equally.In fact, maleic anhydride is generally more cheap than toxilic acid, and when it added in the water-bearing media, it was transformed into the form of acid.
The present composition is included as said other acid of total composition weight 0.01%-45% or their mixture, preferred 1%-25%, more preferably 4%-18%.
According to the present invention, said other acid and said thionamic acid in the present composition preferably with weight ratio 400 to 0.1, more preferably 40 to 0.5, most preferably 10 to 0.5 existence.
According to the present invention, said composition also can comprise multiple annexing ingredient.
The optional components that is fit to comprises tensio-active agent, as nonionic, negatively charged ion, zwitter-ion, both sexes and/or cats product.Preferred said composition is included as total composition weight as many as 40% said tensio-active agent or their mixture, and is preferred 0.05% to 10%, and more preferably 0.1% to 8%, most preferably 0.1% to 3%.
Be applicable to that nonionogenic tenside of the present invention is the alcohol alcoxylates nonionogenic tenside, they can be easily by condensation process preparation well known in the art.Yet most this alcohol alcoxylates, particularly ethoxylation and/or propylated alcohol also are convenient to buy from the market.The tensio-active agent catalogue is available, and it has listed many tensio-active agents, comprises nonionogenic tenside.
Therefore, being used for preferred alkoxylated alcohol of the present invention is formula RO (E)
e(P)
pNonionogenic tenside shown in the H, wherein R is the hydrocarbon chain with 2 to 24 carbon atoms, and E is an oxyethane, and P is a propylene oxide, and e and p represent ethoxylation and propenoxylated average degree respectively, they are 0 to 24.The hydrophobic part of non-ionic compound can be straight or branched primary alconol or the secondary alcohol with 8 to 24 carbon atoms.Being used for present composition preferred nonionic is the condensation product of the alcohol of oxyethane and the linear alkyl chain with 6 to 22 carbon atoms, and wherein ethoxylation degree is 1 to 15, preferred 5 to 12.This suitable nonionogenic tenside can be buied by trade(brand)name DobanolR from for example Shell commercial, or buys by trade(brand)name LutensolR from BASF.These nonionogenic tensides are preferred, do not need to add stablizer or hydrotropic stable prod because found that they can make.When using other nonionogenic tenside, perhaps need to add for example cumene sulfonate or solvent butyldiglycol ether for example of hydrotropic agent.
