In particular, the present invention relates to a linear alkyl polyglycoside of formula A R , -O-(G) n H (A) [wherein, R 1 is a linear C 6~15 alkyl group, n is on average 1 to 5, and G is a monosaccharide of glucose], and a branched alkyl polysaccharide of formula B

Chemical formula

[0004] Water-based cleaning formulations, such as floor care formulations and hard surface cleaning formulations, are widely used. For example, they are used to clean hard surfaces made of materials such as wood, stone, laminate, ceramic, and plastic, such as floors, countertops, walls, and tables, where it is necessary to regularly clean accumulated contaminants, oils, greases, and other pollutants.

[0005] Brand owners and consumers have historically demanded the development of alternative surfactants to those derived from petrochemicals. One proposed alternative was sugar-based surfactants. However, previously proposed sugar-based surfactants have shown poor water solubility, particularly in the presence of salts, and exhibited insufficient cleaning performance when used in a single surfactant system (e.g., without anionic co-surfactants). Recent attempts have sought to overcome this insufficient cleaning performance by exploring sugar-based surfactants with branched hydrophobic substances. However, these materials have lower water solubility than sugar-based surfactants with linear hydrophobic substances, making it difficult to deliver the surfactant to the substrate being cleaned.

[0006] Therefore, there is still a need for water-soluble compositions of sugar-based surfactants with improved cleaning performance.

[0041] Herein, several embodiments of the present invention will be described in detail in the following examples.

[0042] Synthesized S1-S3: alkyl polyglycoside A round-bottom reactor was placed in an aluminum heating block, and a 25 mL Dean-Stark trap (containing 15 mL of hexane) and a magnetic stirring rod were attached. The sugars and n-butanol listed in Table 1 were added to the reactor. The reactor contents were then vigorously stirred under a nitrogen blanket (bubbler). Para-toluenesulfonic acid monohydrate (1 mol%) was added to the stirring reactor contents, and the aluminum heating block was heated to temperature T 1The temperature was set to (as shown in Table 1) and maintained at that temperature for approximately 2-3 hours until the rate of increase in water volume decreased to 0. Next, the reactor contents were cooled to ambient temperature while continuing to stir. Then, alcohol B (molar equivalent of B) was added to the reactor contents as shown in Table 1. Next, the Dean-Stark trap was replaced with a distillation head and condenser flask. Next, the aluminum heating block was set to temperature T 2 The reactor contents were vacuum distilled using the settings described in Table 1, with the condenser flask placed in an ice bath. The vacuum was periodically adjusted to a flow rate of 1-2 drops / second. The vacuum was maintained for 2-4 hours. Then the distillation was stopped. The distillation apparatus was returned to a nitrogen atmosphere, and the stirred contents of the reactor were cooled to ambient temperature. A sodium hydroxide solution was added to the stirred reactor contents as described in Table 1. After vigorous stirring, the pH was measured (on pH paper) to ensure that the reactor contents were basic. A sample of the reactor contents was diluted with hexane and purified by automated column chromatography. The alcohol was eluted from 100% hexane to a mobile phase concentration of 20 / 80 ethyl acetate / hexane. The solvent mixture was then gradientd to 100% ethyl acetate over two column volumes. The solvent system was then changed to ethyl acetate-methanol, and the solvent ratio was gradientd from 60-100% methanol over 1-6 column volumes, during which the product was eluted as a mixture of monosaccharides and polysaccharides. The solvent was removed under reduced pressure to obtain the final product.

[0043] [Table 1] Comparative Examples CF1-CF17 and Examples F1-F8: Cleaning Compositions

[0044] As shown in Table 2, aqueous cleaning compositions containing 5% by weight of alkyl polyglycoside or alkyl polyglycoside mixture in water were prepared in each of the Comparative Examples CF1 to CF4 and Examples F1 to F3.

[0045] As shown in Table 3, aqueous cleaning compositions containing an alkyl polyglycoside mixture at a concentration of 1% by weight in water were prepared in each of the Comparative Examples CF5 to CF17 and Examples F4 to F8. Turbidity

[0046] The turbidity of aqueous cleaning compositions prepared according to Comparative Examples CF1-CF17 and Examples F1-F8 was measured at 20°C using a turbidimeter. The instrument was calibrated according to the instructions included with the apparatus. The results of the turbidity measurements are shown in Tables 2-3. Aqueous cleaning compositions with a measured turbidity of less than 15 turbidimetric turbidity units (NTU) are described as transparent, while those with a turbidity greater than 15 NTU are described as turbid.

[0047] [Table 2]

[0048] [Table 3] Cleaning performance

[0049] The cleaning performance of aqueous hard surface cleaning formulations prepared according to Comparative Examples CF1-CF4 and Examples F1-F3 was determined using the following procedure. Tiles (Premium Excelon Feature Tile & Strip, Chalk II 56830 / L597A, available from Armstrong Flooring) were contaminated with 500 μL of naphtha and carbon black-based contaminants. The contaminants were prepared by mixing 61.04 wt% Naptha 60 / 110, 27.6 wt% Vognis Myritol 318, 8.2 wt% soybean oil, and 3.18 wt% Mogyul L carbon black in a beaker using a stirrer until all the carbon black was suspended. The contaminants were then applied to the center of the tile and spread using a sponge applicator with 20 up-and-down motions while holding the tile at an angle of 45-90° to the ground. The tiles were then left overnight to dry. Next, the tile was placed in a device for holding a non-porous substrate, having a removable well insert with 24 openings, as described in U.S. Patent Application Publication No. 20100083778, the entire disclosure of which is incorporated herein by reference. 400 μL of aqueous hard surface cleaning formulation was filled into each opening and covered with 3 mm needle-punched carpet purchased from The Felt Store Inc. (West Seneca, NY) attached to a 12.7 g cone weight. The plate and tile were mechanically moved back and forth laterally relative to each other to rub the surface of the tile for 5 minutes. The plate was then removed and the surface of the tile was rinsed with deionized water. The rubbed surface of the tile was then analyzed using an EPSON Perfection V500 Photo Scanner and ImageJ software to extract the gray value of each well on the rubbed tile for each formulation. The gray value of each rubbed tile area was then compared to the gray values ​​measured for the original tile before soiling and the soiled area of ​​the tile before cleaning. Please note that a value of 0% corresponds to the gray value of the soiled area before cleaning, and a value of 100% corresponds to the gray value of the original tile before soiling. The results are shown in Table 4.
