Definitions
- the present invention relates to a liquid detergent composition comprising a surfactant and an aminopolycarboxylic add-based organic builder. More specifically, the present invention relates to a high concentration liquid detergent composition having excellent compatibility with a surfactant, superior resistance against white turbidity and good biodegradability.
- liquid detergents particularly in liquid detergents used as a household detergent a nonionic surfactant and/or an anionic surfactant are used as the surfactant and a builder of various types is added to increase detergency.
- a builder of various types is added to increase detergency.
- Various types of organic or inorganic builders can be used but almost all builders have a Na salt structure.
- JP-A-10-36888 discloses a liquid detergent comprising an aminopolycarboxylic acid builder, where an amine salt is disclosed on the same level with an alkali metal salt and in Examples, a Na salt is used. Moreover, the maximum concentration of the surfactant in this composition is as low as 10 wt%, thus, the problem of white turbidity on the high concentration side is not solved.
- the use of a builder has a problem in that the solubility or clouding point of the surfactant as the main agent decreases and thereby the compatibility is deteriorated to cause, for example, white turbidity or separation of the white turbidity into two layers with the elapse of time.
- a technique of diluting the liquid detergent composition with water to reduce the concentration of the surfactant or a technique of adding a solubilizing agent has been heretofore used.
- the former case of diluting the liquid detergent composition with water inevitably results in an increase in the cost of transporting the detergent and this is commercially disadvantageous.
- the effect is not sufficiently high for obtaining a high concentration liquid detergent composition.
- An object of the present invention is to obtain a liquid detergent which has excellent biodegradability, which does not assume strong alkalinity, which has excellent compatibility even if the surfactant concentration is increased, and which is free of white turbidity.
- the present inventors have found that when a nonionic surfactant and/or anionic surfactant is used at a high concentration as the main surfactant of a liquid detergent and an aminopolycarboxylic acid chelating agent is used as a builder, by using an amine salt or an alkali metal-amine mixed salt as the counter ion of the builder and at the same time, adding an alcohol thereto, the compatibility is increased and the white turbidity can be prevented.
- the present invention has been accomplished based on this finding.
- the present invention relates to the liquid detergent composition described below.
- the invention provides a liquid detergent composition comprising:
- the invention provides a liquid detergent composition comprising:
- a further embodiment comprises a liquid detergent composition as described in (1) or (2), wherein the aminopolycarboxylic acid is an amino acid-N,N-diacetic acid.
- An even further embodiment is a liquid detergent composition as described in (1) or (2), wherein the aminopolycarboxylic acid is glutamic acid-N,N-diacetic acid, ⁇ -alanine-N,N-diacetic acid. ⁇ -alanine-N,N-diacetic acid, aspartic acid-N,N-diacetic acid, glycine-N,N-diacetic acid or serine-N,N-diacetic acid.
- another embodiment is a liquid detergent composition as described in any one of (1) to (4), wherein the alcohol is a glycol.
- the surfactant used as component (A) in the present invention is one or more selected from a nonionic surfactant and an anionic surfactant.
- a nonionic surfactant has a higher solubility than an anionic surfactant, accordingly, it is suitable for preparing a high concentration liquid detergent composition.
- the surfactant is used at a concentration of 20 wt% or more in the liquid detergent composition.
- nonionic surfactants include polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, fatty acid diethanolamide, amine oxide and amidoamine oxide.
- suitable anionic surfactants include alkyl sulfate, alkylpolyoxyethylene sulfate, alkylbenzenesulfonate, ⁇ -olefinsulfonate, fatty acid salts, ether carboxylates and monoalkylphosphates. A number of these maybe commercially available.
- the aminopolycarboxylic acid-based chelating agent used in the builder as component (B) of the present invention is a chelating agent containing one or more, preferably one or two amino groups and two or more, preferably three or four carboxyl groups, and having a chelating action.
- the amino group may be a secondary amino group or a tertiary amino group.
- the chelating agent is preferably an amino acid-N,N-diacetic acid.
- An amino acid-N,N-diacetic acid is a compound represented by the following formula (1) A-N-(CH 3 COOH) 2 wherein A-NH 2 represents an amino acid, and -N represents an amino group in the amino acid.
- amino acid-N,N-diacetic acids examples include glutamic acid-N,N-diacetic acid, ⁇ -alanine-N,N-diacetic acid, ⁇ -alanine-N,N-diacetic acid, aspartic acid-N,N-diacetic acid, glycine-N,N-diacetic acid and serine-N,N-diacetic acid.
- amino acid-N,N-diacetic acids may be synthesized by the known Strecker reaction using, for example, an amino acid as the raw material or may be synthesized from a monochloroacetic acid.
- aminopolycarboxylic acid chelating agents include ethylenediaminedisuccinic acid and iminodisuccinic acid. These may also be synthesized by a known method and used. Examples of preferred aminopolycarboxylic acid chelating agents are shown below by their structural formulae.
- amino acid-N,N-diacetic acids and other aminopolycarboxylic acid-based chelating agents are generally obtained as an aqueous solution where all carboxyl groups have a Na salt as the counter ion.
- the aminopolycarboxylic acid for use in the builder as component (B) is used in the form of an amine salt or an alkali metal-amine mixed salt.
- the effect may be obtained using primary, secondary and tertiary amines, however, the amine salt used is preferably an alkanolamine salt, more preferably triethanolanine salt or diethanolamine salt.
- the alkali metal salt in the alkali metal-amine mixed salt is preferably a K salt because it has a higher compatibility with the surfactant than an Na salt, however, in view of the cost, a Na salt is more preferred.
- the Na salt aqueous solution obtained may be treated to remove Na using an H-type cation exchange resin or by electrodialysis, or may be subjected to acid deposition to obtain a crystal having an H type carboxyl group. Thereafter, the resulting solution as it is or in the case of a crystal, a solution obtained by dissolving the crystals in water, is mixed with a mixture of an alkali metal hydroxide such as potassium hydroxide or sodium hydroxide with an amine and thereby an aqueous solution of the objective salt can be obtained. Also, after the removal of Na, the solution or crystal may be added to the formulation of a liquid detergent and then an amine or another alkali metal hydroxide may be added thereto so as to obtain the objective salt.
- an alkali metal hydroxide such as potassium hydroxide or sodium hydroxide
- an aminopolycarboxylic acid-based chelating agent particularly the aminodiacetic acid-type chelating agent is known to exert a good chelate effect namely a builder effect on the neutral to weakly alkali side at a pH of from 8 to 12. Therefore, the amount of the amine or alkali metal hydroxide added is preferably controlled so that the above-described pH region can be created.
- the alcohol used as the solubilizing agent in the present invention is not particularly limited. However, a primary, secondary or tertiary alcohol, preferably a primary or secondary alcohol, having from 1 to 5 carbon atoms, preferably from 2 to 4 carbon atoms is preferred.
- the alcohol maybe a general alcohol such as ethanol and isopropyl alcohol, however, since these are volatile and highly inflammable, a commonly used and inexpensive glycol such as propylene glycol and ethylene glycol is preferably used.
- the liquid detergent composition of the present invention preferably has a composition ratio such that the surfactant as component (A) is from 20 to 60 wt%, preferably from 30 to 50 wt%, the builder as component (B) is from 0.1 to 15 wt%, preferably from 1 to 10 wt%, the solubilizing agent as component (C) is from 0.5 to 30 wt%, preferably from 1 to 20 wt%, and the balance is water as component (D).
- This composition ratio is the proportion among four components (A) to (D).
- the ratio of builder as component (B) based on the surfactant as component (A) is preferably from 2 to 20 wt%, more preferably from 5 to 15 wt%, and the solubilizing agent as component (C) based on the surfactant as component (A) is preferably from 5 to 40 wt%, more preferably from 10 to 30 wt%.
- the ratio of the surfactant as component (A) is less than the above-described range, the cost for transportation or packaging of the liquid detergent increases and this is commercially disadvantageous. If it exceeds the range, the desired compatibility can be attained only within narrow limits. As a result, flexibility in the formulation may decrease or the viscosity may increase and the handleability is disadvantageously impaired.
- the ratio of the builder as component (B) is less than the above-described range, the cleaning effect of the liquid detergent composition decreases, whereas if it exceeds the range, the compatibility with the surfactant occurs only within narrow limits and flexibility in formulation disadvantageously decreases.
- the liquid detergent composition of the present invention may contain, if desired, other additives in any optional ratio, such as a viscosity controlling agent, a moisture retaining agent, an antiseptic, an antifungal agent, a dye and a perfume.
- the detergent composition of the present invention may be used for all uses as a detergent. However, this is suitably used in particular as a home detergent for cleaning dotes or household materials.
- the detergent composition of the present invention may be used as it is or may be used after diluting it with water because the concentration is high.
- a builder comprising an amine salt or amine-alkali metal mixed salt of an aminopolycarboxylic add and a solubilizing agent comprising an alcohol are mixed each in a specific ratio with a specific surfactant, therefore, a high-concentration liquid detergent composition which does not have strong alkalinity, which has excellent compatibility even if the surfactant concentration is increased,, and which is free of white turbidity can be obtained.
- Example 3 and Comparative Example 11 and Comparative Example 6 Example 9 and Comparative Example 12, Example 10 and Comparative Example 13, Example 11 and Comparative Example 14, Example 15 and Comparative Example 17, and Example 16 and Comparative Example 18.
- a high-concentration liquid detergent composition having excellent compatibility and free of white turbidity can be obtained.
