Abstract
Description
[Technical Field]
[0001] The present invention relates to cleaning formulations containing alkoxylated nonanol, particularly laundry detergent formulations and hard surface detergent formulations. The present invention also relates to the use of alkoxylated nonanol in cleaning formulations and to methods for producing cleaning formulations using alkoxylated nonanol. [Background technology]
[0002] Nonionic surfactants are widely used in various fields, such as household and personal care products, due to their advantages such as resistance to hard water, good oil removal ability, and miscibility with other surfactants. A large group of nonionic surfactants that have been developed over decades are alkoxylated aliphatic alcohols, which consist of a hydrophobic group derived from an alcohol such as fatty alcohol, Guerbet alcohol, or oxo alcohol, and a hydrophilic chain or segment derived from an alkylene oxide such as ethylene oxide, propylene oxide, and / or butylene oxide. Alkoxylated aliphatic alcohols have excellent penetration, emulsifying, foaming, and cleaning power, and are environmentally friendly due to their low toxicity risk and high biodegradability.
[0003] Despite the widespread use of alkoxylated aliphatic alcohols, research on this type of nonionic surfactant generally focuses on alkoxylated long-chain alcohols, such as C13. 12 ~C 18 Alternatively, the focus has been on higher alcohols. Few researchers and manufacturers have focused on alkoxylated alcohols with fewer carbon atoms, especially those with branched chains, but several products are already commercially available, for example, C 10 - Alkyl polyethylene glycol ethers based on Guerbet alcohols and ethylene oxide are manufactured and sold by BASF as LUTENSOL® XP.
[0004] When alkoxylated aliphatic alcohols are used in cleaning products, their wetting properties, foaming properties, cleaning power, and other characteristics vary considerably depending on the type of alcohol and the type and amount of alkylene oxide adduct.
[0005] There is a need to find more alkoxylated aliphatic alcohol nonionic surfactants that can provide cleaning formulations with desired overall properties, such as formulation stability and viscosity, foaming power and foam stability, and cleaning power. [Overview of the project] [Problems that the invention aims to solve]

MODE FOR CARRYING OUT THE INVENTION
[0015] The singular forms "a", "an" and "the" include plural referents unless the context clearly indicates otherwise. Terms such as "comprise", "comprising" are used interchangeably with "contain", "containing" and the like, and should be interpreted in a non-limiting open-ended manner. That is, for example, additional components or elements may be present. "Consists of", "consisting of" and expressions of the same kind may be encompassed by expressions of the same kind of "comprises" or "comprising". Terms such as "include", "including" should be interpreted in a non-limiting open-ended manner.
[0016] As used herein, the term "isononanol" is intended to mean an isomer mixture of C9 oxo alcohols commercially produced generally by hydroformylation of a C8 olefin mixture.
[0017] As used herein, "degree of branching" means the sum of the product obtained by multiplying the number of branches of each alkyl alcohol (nonanol) in a mixture of isomeric alkyl alcohols (isononanol) by the proportion thereof. For example, the degree of branching of 1-nonanol is 1, the degree of branching of 2-ethyl-2-methyl-1-hexanol is 2, and the degree of branching of 2,3,4-trimethyl-1-hexanol is 3. The degree of branching of isomeric nonanols is the sum of all values obtained by multiplying the number of branches by the proportion of the respective nonanol.
[0018] In a first aspect, the present invention provides a cleaning formulation comprising alkoxylated nonanol having a degree of alkoxylation in the range of 2 to 20, wherein the alkoxylated nonanol is preferably alkoxylated isononanol.
[0019] <Alkoxylated Nonanol> The alkoxylated nonanol according to the present invention is of formula: RO-(AO) n -H (I) (In the formula, R is a linear or branched C9-alkyl group, particularly a C9-alkyl group derived from isononanol.

[0020] Preferably, alkoxylated nonanol is obtained by alkoxylyzing a mixture of isomer nonanols having a branching degree in the range of 1.1 to 1.5, preferably in the range of 1.1 to 1.4.
[0021] In some embodiments, the alkoxylated nonanol according to the present invention has formula (I), where AO is ethyleneoxy, propyleneoxy, or a combination thereof, preferably ethyleneoxy.
[0022] Polymer segments derived from alkylene oxides of alkoxylated nonanols, for example, in formula (1) "-(AO) n A polymer segment represented by "-" may have a block polymer structure or a random polymer structure if the segment is derived from two or more different alkylene oxides, such as ethylene oxide and propylene oxide.
[0023] Equation (I) -(AO) nIt will be understood that "-" is intended solely to represent a polymer segment having a total of "n" alkylene oxy units and is not intended to impose any limitations on its polymer structure. If the segment is derived from two or more different alkylene oxides, such as ethylene oxide and propylene oxide, the exponent "n" in "-(AO)n-" represents the total number of ethylene oxy units and propylene oxy units, regardless of their arrangement within the segment.
[0024] It will also be understood that alkoxylated nonanols can be mixtures of alkoxylated compounds with respect to their degree of alkoxylation. In this case, the exponent n in formula (I) can be a decimal.
[0025] In some preferred embodiments, the alkoxylated nonanol is a mixture of isononanol alkoxylated compounds, taking into account the fact that isononanol is an isomer mixture. This alkoxylated nonanol can be a mixture of alkoxylated compounds with respect to the degree of alkoxylation. In this case, the exponent n in formula (I) can be a decimal.
[0026] Preferably, the alkoxylated nonanol according to the present invention is a mixture of isononanol alkoxylated products having the same degree of alkoxylation in the range of 2 to 20.
[0027] In some embodiments, the alkoxylated nonanol according to the present invention is a mixture of isononanol ethoxylated compounds having the same degree of alkoxylation in the range of 2 to 20.
[0028] The alkoxylated nonanols according to the present invention as described herein preferably have a degree of alkoxylation in the range of 3 to 14, more particularly in the range of 5 to 10, and even more particularly in the range of 7 to 9, for example, 7, 8 and 9. The alkoxylated nonanols according to the present invention as described herein preferably have a degree of alkoxylation in the range of 3 to 14, more particularly in the range of 5 to 10, and even more particularly in the range of 7 to 9, for example, 7, 8 and 9.
[0029] In particular, the alkoxylated isononanol according to the present invention as described herein preferably has a degree of alkoxylation in the range of 5 to 10, more preferably in the range of 7 to 9, for example, 7, 8 and 9. In particular, the alkoxylated isononanol according to the present invention as described herein preferably has a degree of alkoxylation in the range of 5 to 10, more preferably in the range of 7 to 9, for example, 7, 8 and 9, and is ethoxylated isononanol.
[0030] Alkoxylated nonanols can be prepared by adding alkylene oxides, such as ethylene oxide, propylene oxide, or mixtures thereof, to nonanol in the presence of an alkali metal catalyst such as potassium hydroxide or sodium hydroxide in the conventional manner. In particular, alkoxylated isononanols can be prepared by adding alkylene oxides, such as ethylene oxide, propylene oxide, or mixtures thereof, to isononanol by conventional methods in the presence of an alkali catalyst such as potassium hydroxide or sodium hydroxide.
[0031] In some preferred embodiments, the nonanol for preparing the alkoxylated nonanol is isononal. Suitable isononal (i.e., a mixture of isomers of C9 oxo alcohols) for preparing the alkoxylated isononanol according to the present invention may be, for example, commercially available from BASF. Isonononal prepared via the hydroformylation pathway by known methods may also be used for the preparation of the alkoxylated isononanol according to the present invention.
[0032] Generally, methods for preparing isononanol involve two or more steps and start with butene. In the first step, a mixture of isomers of octene is obtained by dimerizing butene. This octene mixture is then hydroformylated to obtain a C9 aldehyde, which is then hydrogenated to obtain a mixture of nonanol isomers, often referred to as isononanol. Details of preferred methods regarding hydrocarbon feedstocks as raw materials for butene, catalysts, process conditions, etc., are described in numerous patent applications, for example, German Patent Application Publication No. 19924339A1, International Publication No. 01 / 48049A1, or U.S. Patent No. 9090553B2.

[0120] Isononanol is commercially available from BASF. The branching degree of isononanol will be discussed later.
[0121] Alkoxylated nonanol nonionic surfactants were prepared according to the process described below.
[0122] In specific embodiments, the following anionic surfactants were used: LAS: Linear alkylbenzene sulfonates, commercially available from BASF. LABSA: Linear alkylbenzene sulfonic acid, which is commercially available from BASF, and AES: A commercially available alcohol ethoxysulfate from BASF.
[0123] II. Preparation INA 7 was prepared according to the following process.
[0124] 797 g of isononanol (from BASF) and 4.3 g of catalyst KOH (88%, solid) were charged into a 5 L pressure reactor. After introducing 3.5 bar of nitrogen, the pressure was evacuated until it reached 0.3 bar, and this introduction-evacuation process was repeated. Vacuum was applied at 200 mbar for 15 minutes, followed by 80 mbar for 30 minutes, with a stirring speed of 150 rpm and a temperature of 115°C.
[0125] Once the moisture content fell below 1,000 ppm, 3.5 bar of nitrogen was introduced into the pressure reactor and discharged until the pressure reached 0.3 bar. This introduction-discharge process was repeated three times. Next, 0.5 bar of nitrogen was introduced into the pressure reactor, the stirring speed of the pressure reactor was set to 400 rpm, and the temperature was heated to 130°C. 1703 g of ethylene oxide (EO) was introduced into the pressure reactor at an EO flow rate of 450 g / h, and the heat of reaction was used to raise the alkoxylation temperature to a range of 160°C to 180°C. After the introduction of EO was complete, the reaction system was held at 170°C for 1 hour. After analysis and identification, the reactor was cooled to 60°C. Then, 4.1 g of acetic acid was added to the reactor and stirred for 15 minutes to obtain the neutralized product, which was then discharged into a bottle at a temperature below 60°C.
[0126] Other alkoxylated isononanol nonionic surfactants were prepared using the same process, except that isononanol, ethylene oxide (EO), and KOH were introduced in the amounts summarized in Table 1 below.
[0127] [Table 2]
[0128] Preparation of comparative examples: INA for comparison: The same synthesis method was used for the preparation of the comparative examples, except that a different isononanol (EXXAL® 9 from Exxon Mobile) was used. The amounts of ethylene oxide (EO) and KOH introduced are summarized in Table 2 below.
[0129] [Table 3]
[0130] Measurement and calculation of branching degree:
[0131] [Table 4]
[0132] Measurement method: The retention times of each isomer were confirmed by GC-FID. The ISO index is calculated as the sum of the number of branches multiplied by the ratio. For example, the number of branches of nonanol-1 is 1, according to the number of branched methyl groups, the number of branches of 2-ethyl-2-methylhexanol-1 is 2, and the number of branches of 2,3,4-trimethylhexanol-1 is 3. The ratios are analyzed by GC-FID. The lower the ISO index, the higher the linearity of the molecules in each fraction.
[0133] The degree of branching of isononanol for preparing the alkoxylated isononanol examples is calculated as shown in the table below.
[0134] [Table 5]
[0135] The table below shows the results regarding the degree of branching of isononanol used in the preparation of the embodiment of the invention.
[0136] [Table 6]
[0137] [Table 7]
[0138] III. Examination Methods Viscosity of the sample and formulation: The viscosity of the sample and formulation was confirmed using a viscometer (DV2T LVT from Brookfield) fitted with spindle 63, at 60 rpm and 25°C.
[0139] Stability of the sample and formulation: The samples and formulations were placed in a stability testing chamber (BPHS-060A from Yiheng Technology Co. Ltd.) and the temperature was set separately to constant temperatures of 5°C, 10°C, 23°C, 40°C, and 60°C. Subsequently, the samples and formulations were visually observed for the presence or absence of turbidity, phase separation, and solidification for up to 8 weeks.
[0140] Dissolution of the compound: 0.4g of detergent compound (colored with red dye) was added to 200ml of cold hard water (10℃, Ca / Mg 3:2) while magnetically stirring at 300rpm (RET Basic from IKA). The dissolution time was determined visually by the time it took for the detergent compound to completely disperse in the water (using the dye as an indicator).
[0141] Foaming and stability (Rosmiles): To test foaming and stability using the Rossmiles method, a 550 ml detergent solution (2 g / L detergent) was prepared in hard water (Ca / Mg 3:2, calculated as 250 ppm CaCO3). First, 50 ml of the detergent solution was pre-filled into a graduated cylinder, and then the remaining 500 ml of the detergent solution was allowed to flow into the cylinder via a spherical glass container. The amount of foam was recorded after 30 seconds and 5 minutes.
[0142] Foaming and stability: To test foaming and stability using the foaming chamber method, 40 ml of detergent solution (2 g / L detergent) was prepared in hard water (Ca / Mg 3:2, calculated as CaCO3, 250 ppm). The detergent solution was placed in a 280 ml graduated cylinder, and the cylinder was rotated at 30 rpm for 120 seconds. The foam height was observed as the initial foam, and the foam volume after 2 minutes, 5 minutes, and 10 minutes was recorded as a value representing foam stability.
[0143] Foam retention: To test foam retention using the foaming box method, 40 ml of detergent solution (6 g / L detergent) was prepared in hard water (Ca / Mg 3:2, calculated as CaCO3 at 250 ppm). After loading the detergent solution into a 280 ml graduated cylinder, the cylinder was rotated at 30 rpm for 60 seconds to obtain initial foam. Next, 50 μl of standard dirt (GB 9985) was added to the detergent solution, and the cylinder was rotated at 30 rpm for 60 seconds. The amount of foam was recorded each time 50 μl of the standard dirt was added, and this was continued until all the foam disappeared, and the total amount of dirt added to the detergent solution was calculated.
[0144] Cleaning kitchen stains: Kitchen stains were prepared based on the composition shown in Table 2 below. These stains were then applied to stainless steel using a brush, adjusted to a weight of approximately 2 ± 0.2 g. The stained stainless steel was degraded in an oven at 160°C for 30 minutes.
[0145] The test formulation was sprayed (four times) onto a deteriorated contaminated surface and left for one minute. Finally, the surface was rinsed with water for 10 seconds, and the weight was measured after drying.
[0146] [Table 8]
[0147] Soap scum removal: Soap scum stains were prepared based on the compositions shown in Tables 3 and 4 below. These stains were then applied to the ceramic surface using a brush, with the weight adjusted to approximately 0.5 ± 0.05 g. The stained ceramic was then degraded in a 180°C oven for 30 minutes.
[0148] One drop of the test compound was placed on the contaminated surface for a set period of time (1 minute / 2 minutes / 3 minutes). Finally, the surface was rinsed with water for 20 seconds, and the performance was determined by visual observation.
[0149] [Table 9]
[0150] [Table 10]
[0151] Removal of limescale (marble slab immersion test): A marble slab (3cm x 2cm x 1cm) was immersed in the test mixture for 10 minutes. The marble slab was then rinsed with water, dried at 105°C, and weighed. The same marble slab was repeated three more times, and the total weight loss and removal rate were calculated.
[0152] Hot water washing: In the laboratory, the laundry process was simulated using a turgotometer (RHLQ-IV from RIDCI) containing 16 wash tubs, each equipped with an agitator. Each wash tub was filled with 1 liter of water and operated at a uniform agitation speed of 120 revolutions per minute (rpm). Unless otherwise specified, 8 to 12 soiled cloths (6 cm x 6 cm square pieces, with a minimum of 3 pieces per stain) were immersed in the water in each wash tub, a detergent mixture was added, and the wash cycle was performed at 30°C for 20 minutes. After washing, the test pieces were removed from the wash tub, drained, rinsed twice with 10 liters of tap water for 30 seconds each, and then dried overnight at ambient temperature.
[0153] Cold water wash: In the laboratory, a turgotometer (RHLQ-III from Shanghai Bank Equipment Co. Ltd., China) was used to simulate the laundry process following the same steps as described in "Hot Water Washing." The only difference from "Hot Water Washing" was the application of 15°C to verify the washing performance at low temperatures.
[0154] Measurement of changes in whiteness: For the fabrics before and after the washing process, the reflectance value (in %) representing the whiteness was measured at 457 nm by photometry using an integrating sphere reflectometer (Datacolor, SF 500 model from the USA, wavelength range 360-700 nm, optical geometry d / 8°) equipped with a UV cutoff filter. The change in reflectance (ΔR) represents the change in the whiteness of the fabric before and after washing and is used to evaluate the stain removal performance of each detergent formulation in the following examples. A high ΔR value indicates high cleaning performance.
[0155] The following fabrics were used in the tests in the examples: JB 01: Carbon black / oil-contaminated cotton, standard contaminated cloth according to GB-T13174-2008, available from China Research Institute of Daily Chemical Industry. JB 02: Cotton contaminated with pigments / proteins, standard contaminated cloth according to GB-T13174-2008, available from China Research Institute of Daily Chemical Industry. JB 03: Cotton contaminated with pigments / sebum, standard contaminated cloth according to GB-T13174-2008, available from China Research Institute of Daily Chemical Industry. WFK 10D: Cotton contaminated with pigments / sebum, from WFK Testgewebe GmbH, Germany. WFK 20D: Pigment / sebum-stained polyester, from WFK Testgewebe GmbH, Germany. CS-61: Cotton contaminated with beef tallow and colored with Sudan Red, from the Center for Test Materials, Netherlands. PS-61: Beef tallow-contaminated, Sudan Red-colored polyester, from Center for Testmaterials, Netherlands. CS-62: Cotton contaminated with lard, colored with Sudan Red, from the Center for Testmaterials, Netherlands, and PS-62: Polyester contaminated with lard, colored Sudan Red, from Center for Testmaterials, Netherlands.
[0156] IV. Test Results IV.1 Stability of Nonionic Surfactants
[0157] [Table 11]
[0158] At 10°C, all nonionic surfactant samples solidified. After 6 weeks at 23°C, INA ethoxylates such as INA 7, INA 8, and INA 9 remained fluid despite phase separation, while C12 / 14(EO)9 and C10 ethoxylates (C10(EO)7, C10(EO)8, and C10(EO)10) solidified. The C10 ethoxylates also became turbid at 40°C and heterogeneous after 6 weeks.
[0159] IV.2 Formulation and Performance The amounts of the components shown in the table below are expressed as weight percentages unless otherwise specified. Unless otherwise specified, percentages are usually based on total weight.
[0160] Group A: Non-concentrated liquid laundry detergent formulation (pH=8)
[0161] [Table 12]
[0162] [Table 13]
[0163] All formulations were stable for more than 8 weeks in the temperature range of 5°C to 40°C. Formulation A-1 of the present invention, containing INA 7, dissolves more rapidly than the others. Both formulation A-1 containing INA 7 and formulation A-2 containing INA 9 exhibit improved properties in terms of foaming, stability, and cleaning performance against stubborn stains.
[0164] Group B: Non-concentrated liquid laundry detergent (pH=8)
[0165] [Table 14]
[0166] [Table 15]
[0167] Both formulation B-1, which contains INA 7, and formulation B-2, which contains INA 9, exhibit improved properties in terms of viscosity control and cleaning performance against stubborn stains in both hot and cold water washing. In particular, formulation B-1, which contains INA 7, shows a significant improvement in cleaning performance against stubborn stains.
[0168] Comparative formulations B-5 containing C10(EO)7 and B-6 containing Iso-C13(EO)7 also exhibit good viscosity control and cleaning effectiveness against stubborn dirt. However, C10(EO)7 was observed to cause phase separation at lower temperatures (i.e., 5°C) and have a lower cleaning effect against ordinary dirt, while formulations containing Iso-C13(EO)7 caused turbidity even at room temperature (i.e., 25°C).
[0169] Group C: Concentrated liquid laundry detergent formulation (pH=8)
[0170] [Table 16]
[0171] [Table 17]
[0172] Formulation C-4 was formulated with 3% ethanol as a solvent to reduce viscosity and maintain the compatibility of the formulation. However, ethanol, being a volatile solvent, is unsafe during transport and manufacturing. This does not contribute to cleaning performance or other detergent properties. Furthermore, formulations containing ethanol still do not exhibit stability when stored at low temperatures. At 15°C and 5°C, fluidity decreases or is lost.
[0173] When organic solvents such as ethanol were not present in the formulation, either turbidity or high viscosity was observed, as seen in comparative formulations C-5 to C-10.
[0174] The isononanol ethoxylate according to the present invention has been found to be able to control the viscosity and stability of the formulation even at 5°C, as observed in formulations C-1 to C-3 of the present invention.
[0175] On the other hand, the formulation of the present invention containing INA 7 to INA 9 showed a significant improvement in the ability to remove stubborn stains.
[0176] Group D: Single-dose (SUD) formulation (pH=8)
[0177] [Table 18]
[0178] [Table 19]
[0179] MPG (1,2-propylene glycol), DPG (dipropylene glycol), and glycerol are the most commonly used solvents in SUD formulations to balance the compatibility, stability, and film tolerance of the formulation, and they do not contribute to the cleaning performance or other detergent properties.
[0180] Surfactants such as C10 Guerbet alcohol ethoxylates / alkoxylates (e.g., C10(EO)7 from BASF) were widely used in SUD formulations, particularly those containing a large amount of nonionic surfactants, to reduce viscosity and maintain the compatibility and stability of the formulation during low-temperature storage.
[0181] A comparative formulation containing the common nonionic surfactant C10(EO)7 showed turbidity or precipitate formation after 4 weeks of storage at 5°C and -5°C, depending on the solvent system.
[0182] Surprisingly, it was found that replacing the nonionic surfactant C10 Guerbet alcohol ethoxylate (C10(EO)7) with the nonionic surfactant INA 7 according to the present invention significantly improves the storage stability of the SUD formulation at 5°C without reducing its cleaning performance, even when MPG or DPG is used as the solvent.
[0183] Group E: Single-dose formulation (pH=8)
[0184] [Table 20]
[0185] [Table 21]
[0186] Surprisingly, formulation E-1, which contains the nonionic surfactant INA 7 according to the present invention, was found to have significantly improved viscosity and stability at 5°C compared to comparative formulation E-2, even without the presence of 5% glycerol, which imparts higher stability compared to other comparative formulations. On the other hand, formulation E-1 was observed to have far superior performance in removing stubborn stains due to the contribution of INA 7.
[0187] Group F: Single unit dose formulation (pH=8)
[0188]
Table 22
[0189]
Table 23
[0190] Compared with glycerol, MPG exhibits higher efficiency in SUD formulations, but is also more expensive. It is even more difficult to reduce the content of MPG in SUD formulations. It has been recognized that when conventional nonionic surfactants are used as nonionic surfactants and MPG is reduced by 5% from SUD formulations, either a significantly high viscosity or formulation compatibility problems will occur, as can be seen from the comparison between comparative formulation F-2 and comparative formulations F-3 to F-7.
[0191] Surprisingly, it has been found that even when the amount of MPG used is reduced by 5% compared to comparative formulation F-2, formulation F-1 containing INA 10 according to the present invention still exhibits better viscosity and stability at 5°C. Meanwhile, it was observed that formulation F-1 has much higher removal performance for stubborn stains.
[0192] Group G: Powder laundry detergent formulation (pH=12, 1% aqueous solution)
[0193]
Table 24
[0194]
Table 25
[0195] It has been found that formulation G-1 containing INA 7 according to the present invention exhibits higher detergency against stubborn stains in powder detergents than natural C12 / 14 ethoxylate.
[0196] Group H: Dishwashing formula for hand washing (pH=7)
[0197] [Table 26]
[0198] [Table 27]
[0199] The formulations according to the present invention, which include isononanol ethoxylate, a nonionic surfactant, particularly INA 7, exhibit superior foaming ability in hand-washing applications compared to conventional formulations containing nonionic surfactants such as C12 / 14(EO)7 and Iso-C13(EO)8.
[0200] [Table 28]
[0201] When dirt is added to the test solution, formulation H-1 of the present invention, containing 6% INA 6 and 6% C12 / 14(EO)7, and formulation H-2 of the present invention, containing 6% INA 7 and 6% C12 / 14(EO)7, can maintain foam height far better than the comparative formulation H-6, which contains 12% C12 / 14(EO)7. This is a very important performance characteristic for dishwashing detergents, as foam is the most easily understood indicator for the end user to determine whether the detergent's effect is still present.
[0202] [Table 29]
[0203] It was found that Formulations H-4 and H-5 of the present invention, each containing 12% of INA 6 or INA 7, respectively, exhibit even better foam retention than Comparative Formulation H-6 containing 12% of C12 / 14(EO)7. This indicates that the isononanol ethoxylate, which is the nonionic surfactant according to the present invention, is an excellent nonionic surfactant that stably maintains foam in the presence of dirt.
[0204] Group I: Formulations for kitchen cleaning (pH=11)
[0205]
Table 30
[0206]
Table 31
[0207] Formulations H-1 and H-2 containing INA 5 or INA 7, respectively, remove more kitchen dirt from stainless steel surfaces than comparative formulations containing conventional nonionic surfactants C12 / 14(EO)7, C10(EO)7 and C10(EO)8.
[0208] Group J: Formulations for bathroom cleaning (pH=3)
[0209]
Table 32
[0210]
Table 33
[0211] All formulations containing the nonionic surfactant nonanol ethoxylate according to the present invention, particularly formulations containing INA 7 (H-2) or INA 9 (H-3), remove soap scum from ceramic much more rapidly than comparative formulations at 1 minute and 2 minutes after the detergent is dropped onto the test surface.
[0212] Group K: Toilet cleaning formulation (pH<1)
[0213] [Table 34]
[0214] [Table 35]
[0215] The marble slab immersion test is a method that simulates the removal of limescale during toilet flushing. The present invention's formulation H-1, which contains INA 7, exhibits better cleaning performance than comparative formulations containing the conventional nonionic surfactants C12 / 14(EO)7 and C10(EO)7.
[0216] While this specification has described the present invention with reference to specific embodiments, it should be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It will be apparent to those skilled in the art that modifications and variations of the methods and apparatus of the present invention can be made without departing from the spirit and scope of the invention.

The bubble pressure is measured as a function of the bubble's lifetime and can be correlated with the surface tension according to the Young-Laplace equation.
[0220] Equipment and materials: 1.SITA T60 (Sita Messtechnik, Germany) 2.Water bath 3. Heating and stirring plate 4. Glass beaker 5. Glass vial (100 mL)
[0221] The SITA science line T60 was calibrated with deionized water. The surface tension of the clean water sample after calibration should be 72.0 ± 1.0 mN / m (dependent on water quality and temperature). After calibration, the SITA was programmed to take readings at desired time intervals (i.e., 0.1, 1.0, and 10.0 seconds).
[0222] 100 ml of 0.1% surfactant (ethoxylated isononanol) was transferred to a 100 ml vial and immersed in a water bath heated to 23°C ± 1°C. The sample was equilibrated in the water bath for 30 minutes. The sample was then tested with SITA. After each sample was tested, the SITA was washed, and then the surface tension of the deionized water was checked to ensure that the SITA was sufficiently clean. If the measured value of the deionized water was not within the range of 72.0 ± 1.0 mN / m, the washing procedure was repeated. The surface tension (mN / m) against the lifetime of bubbles at 23°C was recorded. The experimental data are shown in the table below.
[0223] [Table 37]
[0224] The lower dynamic surface tension value obtained with the isononanol of the present invention means that the surfactant properties are superior to those of a comparative isononanol with the same EO number.
[0225] Emulsification ability test >Test conditions: Product content in a deionized aqueous solution at 23°C: 2 g / L >Oil type: Anti-wear hydraulic fluid L-HM 46# (UK CULL) >Testing method: 1) Place 20 ml of oil and 20 ml of 2 g / L surfactant solution into a 100 ml graduated cylinder. 2) After inverting for 1 minute, record the time it takes for a 10 ml layer to form.
[0226] [Table 38]
[0227] A longer time means better emulsification performance. Compared to the inventive examples with the same number of EOs, the comparative examples with a much higher degree of branching were shown to have relatively lower emulsifying power.
[0228] Testing of biocides in liquid laundry detergent formulations
[0229] [Table 39]
[0230] [Table 40]
[0231] Liquid laundry detergent formulations containing 0.3% Tinosan® HP 100 (from BASF), which is the nonionic surfactant and / or biocide of the present invention, or 1% phenoxyethanol (Protectol® PE, BASF), are prepared according to Examples L-1 to L-4. This formulation is prepared by first preparing a premix containing the surfactant, solvent, citric acid, and NaOH shown in Table 6, and water to reach 90%. This premix is prepared by adding appropriate amounts of water to all components and stirring at room temperature. Then, the pH is set to pH=8.5 using NaOH. Next, 90% of this premix, containing the nonionic surfactant of the present invention and / or Tinosan® HP 100 (a commercially available BASF SE product containing 30% of 4,4'-dichloro-2-hydroxydiphenyl ether (CAS 3380-30-1), an antimicrobial active substance) and 2-phenoxyethanol (CAS 122-99-6) in appropriate concentrations, is mixed with water to 100% and stirred at room temperature to prepare the final formulation. For comparison, a standard liquid detergent formulation containing an AEO-type nonionic surfactant (C12 / 14 7EO, BASF) is prepared.
[0232] As shown in Table 2, formulations L-1 and L-2 containing INA 7, and formulations L-3 and L-4 containing INA 9, all showed compatibility in the presence of the biocide Tinosan® HP 100 (from BASF) 0.3% or phenoxyethanol (Protectol® PE, BASF) 1%, and remained stable after storage tests.
[0233] Cleaning performance test:
[0234] [Table 41]
[0235] [Table 42]
[0236] Both formulation M-1, which contains INA 7, and formulation M-2, which contains INA 9, show improved cleaning performance against stubborn stains. In comparative examples, formulations M-3, which contains Com.INA 7, and Com.INA 9 are found to have a lower cleaning effect against stubborn stains.
[0237] Stability test of concentrated liquid laundry detergent formulations
[0238] [Table 43]
[0239] [Table 44]
[0240] Concentrated liquid laundry detergents use solvents such as ethanol to obtain formulations with good compatibility and appearance. However, volatile solvents are unsafe during transport and manufacturing. This does not contribute to cleaning performance or other detergent properties. On the other hand, even if ethanol is included in the formulation, stability is not achieved during low-temperature storage. At 15°C and 5°C, fluidity decreases or is lost.
[0241] When organic solvents such as ethanol were not present in the formulation, turbidity or phase separation was observed, as seen in comparative formulation N-3 containing comparative example Com.INA 9. On the other hand, the present invention formulation N-1, which contains the inventive example INA 7, is clear and stable at room temperature or high temperature.
[0242] In the invention example, formulation N-2 containing INA 9 was found to be transparent and stable even at low temperatures (e.g., 5°C). On the other hand, comparative formulation N-4 containing INA 9 lost its fluidity at low temperatures.
[0243] Foam retention test of dishwashing agent formulation (pH=7)
[0244] [Table 45]
[0245] When dirt is added to the test solution, formulations P-1 containing 1% INA 7 and P-2 containing 1% INA 9, which are the formulations of the present invention, can maintain a much better foam height than the comparative formulations P-3 containing 1% comparative INA 7 and P-4 containing 1% comparative INA 9. This is a very important performance characteristic for dishwashing detergents, as foam is the most easily understood indicator for the end user to determine whether the detergent's effect is still present.
[0246] Oil release test of dishwashing agent (pH=7) Test method: To test the cleaning performance by lifting the oil, 80 ml of detergent solution (50 g / L detergent) was prepared in hard water (Ca / Mg 3:2, calculated as CaCO3, 250 ppm). 0.1 g of chili oil (soybean oil and chili peppers, commercially purchased) was applied to a ceramic spoon so that the bottom of the spoon was evenly covered. The spoon coated with chili oil was immersed in the aforementioned detergent solution, and the time from the start until all the chili oil peeled off the spoon was recorded.
[0247] [Table 46]
[0248] Formulation B-1 of the present invention, containing 0.6% INA 9, was found to have better fluidity at low temperatures (lower viscosity) than comparative formulation B-2, containing 0.6% C12 / 14(EO)9, which means it is easier for consumers to handle even in winter.
[0249] Formula Q-1 also shows that it lifts oil from ceramic spoons much faster than Formula Q-2 without mechanical force. This indicates that Formula B-1, which contains INA 9, has superior oil-removing properties when washing dishes by hand.
