Description

[Technical field]

[0001] The present invention relates to a premix comprising an alkyl polyglycoside, a hydrotrope and a solvent, where the alkyl polyglycoside has an alkyl chain of 10 to 16 carbon atoms, the hydrotrope is preferably sodium cumene sulfonate and the solvent is preferably water. [Background technology]

[0002] Sugar surfactants, such as alkyl polyglycosides, are distinguished by excellent cleaning properties and high ecotoxicity compatibility.For this reason, these classes of nonionic surfactants are becoming more and more important.They are commonly used in the formulation of liquid and powder detergents, such as, for example, laundry detergents and dishwashing detergents and hair shampoos.

[0003] Typically, commercially available alkyl polyglycosides are 10 -C 16 For alkyl polyglycosides with longer alkyl chain lengths, such as alkyl polyglycosides, about 40% to up to 50% and C8-C 10 In the case of alkyl polyglycosides with shorter alkyl chain lengths, such as C, C10, C20, C30, C40, C50, C60, C70, C80, C90, C100, C120, C140, C160, C180, C200, C300, C400, C500, C60, C70, C80, C90, C120, C140, C160, C180, C160, C180, C200, C16 ... 10 -C 16 Increasing the active level of alkyl polyglycosides can cause undesirable high viscosity of the product at low temperatures, making it difficult to handle in cold or winter conditions. Most notably, 10 -C 16 Certain alkyl polyglycosides, such as alkyl polyglycosides, exhibit unacceptably high viscosities at low temperatures when transported, such as by injection or pumping. In addition, the higher alkyl (C 10 -C 16) polyglycosides, due to their supersaturated state, tend to crystallize during storage below 30°C. 10 -C 16 Alkyl polyglycosides become cloudy, i.e., cloudy and opaque in appearance, as the solids contained therein exceed their supersaturation state, which is a highly undesirable phenomenon and makes it difficult to achieve uniform product quality. To solve this problem, 10 -C 16 The alkyl polyglycoside solution must be heated to resolvate the crystals and reduce the viscosity, which makes the process expensive and time consuming, or the use of C8-C 10 However, this solution required a high concentration of low alkyl chain polyglycosides (>20%) to achieve the desired properties. Therefore, the C 10 -C 16 It is possible to reduce the viscosity and prevent the solid crystallization without excessively diluting the alkyl polyglycoside with other ingredients, C 10 -C 16 It remains a challenge to obtain an alkyl polyglycoside composition containing an alkyl polyglycoside. 10 -C 16 Compositions containing alkyl polyglycoside solutions can facilitate processes in preparing cleaning formulations containing alkyl polyglycosides.

[0045] Premix General Procedures and Settings The premixing process was carried out by setting up an overhead mechanical stirrer (RW 20 Digital from IKA) and a water bath (HWS-26 from Yiheng Technology Co. Ltd).

[0046] All the raw materials of the premix were preheated in an oven (Binder FD 115) at 40°C for at least 1 hour to ensure thorough homogenization. The preheated alkyl polyglycoside was then pre-charged into a vessel whose temperature was controlled by a water bath. Stirring was started at a speed of 100 rpm to 500 rpm, and the hydrotrope and / or solvent were dosed into the vessel stepwise within a specific time period. After dosing, stirring was maintained for 0.5 to 3 hours to obtain the final premix.

[0047] Premix Stability Testing The prepared premixes were filled into glass bottles and tested at various temperatures. Then the bottles containing the premix samples were separately placed into constant temperature stability test chambers (BPHS-060A, Yiheng Technology Co. Ltd.) at 5°C, 10°C, 20°C, and 30°C.

[0048] The viscosity of the premix samples was checked by a viscometer (Brookfield DV2T LVT) equipped with a temperature cycler (Brookfield TC-550MC) and visual observation was made to see if crystallization had occurred. The viscosity and crystallization status were then tracked and recorded until crystallization occurred or for up to 12 weeks.

[0049] Pour Point Measurement Pour point is a physical property of a chemical that indicates the feasibility of handling the chemical at various temperatures. It was measured by an automatic cloud and pour point tester (HCP 852 from WALTER HERZOG GmbH) according to ASTM D5950.

[0050] Experimental Tests and Data 1.C with sodium cumene sulfonate 10 -C 16 Stability test of premixes containing APG (APG-1) Following the general procedure and setup of the premix, 145.45 g of APG-1 (50-53% aqueous solution) was mixed with 54.55 g of sodium cumene sulfonate (40% aqueous solution). (Alkyl polyglycoside used: APG-1, commercially available from BASF).

[0051] The premix process was carried out according to the method for determining apparent viscosity as specified in ISO 2555 using a four-blade propeller stirrer (IKA R 1342) at a stirring speed of 300 rpm and in a water bath at 45° C. for 30 min.

[0052] After stability testing of the premixes, the viscosity and crystallization state were tracked and recorded, and the results are shown in Table 1.

[0053] [Table 1]

[0054] The results show that the premix containing APG-1 and an aqueous solution of sodium cumene sulfonate can be easily handled even when the temperature is below 5°C and is stable between 5°C and 30°C for at least 12 weeks without crystallization. The viscosity was always below 300 mPa.s from 5°C to 30°C, so no reheating was required. Therefore, it can be easily handled during transportation, storage, and loading / unloading.

[0055] 2. C with Various Solvents 10 -C 16 Stability test of premixes containing APG (APG-1) Following the general procedure and setup of the premix, APG-1 (50-53% aqueous solution) and various solvents were mixed (alkyl polyglycoside: APG-1 commercially available from BASF).

[0056] The premix process was carried out according to the method for determining apparent viscosity specified in ISO 2555 using a four-blade propeller stirrer (IKA R 1342) at a stirring speed of 300 rpm and in a water bath at 45° C. for 30 min.

[0057] After stability testing of the premixes, the viscosity and crystallization state were tracked and recorded, and the results are shown in Table 2.

[0058] [Table 2]

[0059] Premixes of water and organic solvents commonly used in liquid laundry and dishwashing detergent formulations are 10 -C 16Although the viscosity of APG can be significantly reduced, this still does not prevent crystallization at low temperatures, especially at 5°C.

[0060] 3. C4-C as a hydrotrope 10 C with alkyl polyglucosides 10 -C 16 Stability testing of premixes containing alkyl polyglucosides Following the general procedure and setup of the premix, alkyl polyglycosides were mixed in aqueous solution with or without hydrotrope (alkyl polyglycosides: APG-1 commercially available from BASF).

[0061] The premix process was carried out according to the method for determining apparent viscosity specified in ISO 2555 using a four-blade propeller stirrer (IKA R 1342) at a stirring speed of 300 rpm and in a water bath at 45° C. for 30 min.

[0062] After stability testing of the premixes, the viscosity and crystallization state were tracked and recorded, and the results are shown in Table 3.

[0063] [Table 3]

[0064] C8-C 10 Low alkyl chain polyglycosides such as alkyl polyglucosides are easy to handle and have the C 10 -C 16 It can also be used as a hydrotrope by premixing with alkyl polyglucosides, however high concentrations of low alkyl chain polyglucosides (>20%) are required to achieve the desired properties.

[0065] For example, Premix-6 contains 20% C8-C 10 Alkyl polyglucosides were included, which inhibited crystallization, but the viscosity was still too high at 5°C. 10Alkyl polyglucosides predominated at the 35% dosage level, resulting in both crystallization inhibition and low viscosity. However, C8-C 10 Excessive dilution with alkyl polyglycosides results in C 10 -C 16 This can lead to a significant loss of performance provided by the alkyl polyglycosides.

[0066] In addition, even shorter chain APGs, specifically about 10% C4-C8 alkyl polyglucosides, are also 10 -C 16 Alkyl polyglucoside (C 10 -C 16 APG was premixed with Premix-8 and Premix-9) at a dilution of less than 20%. However, the premixes were not stable at 5°C for more than one month and crystallization was inhibited.

[0067] The results are shown in Table 1. 10 -C 16 This illustrates that premixes containing APG have more desirable stability performance than other premixes containing hydrotropes other than SCS.

[0068] 4. Various weight ratios of C 10 -C 16 Stability study of premixes containing APG (APG-1) and sodium cumene sulfonate Following the general procedure and setup of the premix, alkyl polyglycosides and sodium cumene sulfonate were premixed in an aqueous solution (alkyl polyglycosides: APG-1, commercially available from BASF).

[0070] After stability testing of the premixes, the crystallization status was recorded and the results are shown in Table 4.

[0071] [Table 4]

[0072] The results are shown in Table 1. 10 -C 16 It is shown that the premix containing APG and sodium cumene sulfonate demonstrates excellent stability performance without the appearance of crystals even over a period of more than three months.
