Description
Technical Field
The invention relates to an external structuring system for liquid detergent and a preparation process thereof, and a liquid detergent containing the external structuring system, belonging to the technical field of daily chemical products, in particular to a liquid detergent composition containing insoluble components and application thereof.
Background
In addition to basic detergency, an increasing number of detergent manufacturers are trying to impart more functional points to detergents, such as softness, color protection, long-lasting fragrance retention, and the like. Powder or block products are generally produced by blending different materials, spraying powder or granulating in a fluidized bed, and also by blending different particles, so that the functions are relatively easy to realize in a solid detergent. These functional aspects are very difficult to achieve in liquid products because the compatibility of the functional materials with the liquid detergent matrix can lead to delamination, sedimentation, etc. of the detergent.
It is known that the stability of liquid products is very likely to be caused by chemical reactions or density differences after adding related functional additives. Generally, cationic polymers, cationic surfactants or silicone-based adjuvants provide a softening and color-protecting function, while insoluble particles such as microcapsules, pearlescers or opacifiers provide long-lasting fragrance retention or special appearance. Obviously, in a detergent formulation with a predominant anionic surfactant, the cationic adjuvant will react with the anionic surfactant and the adjuvant and co-precipitate; insoluble particles float or sink due to density differences, resulting in significant stratification.
Structured liquid detergents are one solution to this problem. It is well known that Hydrogenated Castor Oil (HCO) based on 12-hydroxy-octadecanoic triglyceride can form fibrous/fine-packed crystalline glycerides, which crystals have been used for many years for rheology modifiers or external structurants. For example, chinese patent CN1471571A mentions that external structuring systems with added HCO are effective in stabilizing aesthetic imparting agents (such as colored particles, pearlescers, dyes, etc.) and defoamers (including polydimethylsiloxanes complexed with silica).
However, how to improve the external structuring property to give higher stability to the detergent has been a problem in the industry. In the Chinese patent CN1678722A, anionic and nonionic emulsifiers are adopted to accord with the system, and the number of the nonionic emulsifiers is more. Chinese patent CN104685043B is compounded with a relatively large amount of organic alcohol without amino functional group, aiming to improve the shear resistance of the external structurant. It is well known that nonionic emulsifiers generally do not have the same emulsifying power as anionic emulsifiers, and therefore the emulsifying power of anionic emulsifiers is severely affected by the presence of high proportions of nonionic emulsifiers and alcohol solvents, and the external structuring properties are affected.

The term "weight content" herein may be represented by the symbol "%".
All formulations and tests herein occur at 25 ℃ environment, unless otherwise indicated.
The use of "including," "comprising," "containing," "having," or other variations thereof herein, is meant to encompass the non-exclusive inclusion, as such terms are not to be construed. The term "comprising" means that other steps and ingredients can be added that do not affect the end result. The term "comprising" also includes the terms "consisting of …" and "consisting essentially of …". The compositions and methods/processes of the present invention can comprise, consist of, and consist essentially of the essential elements and limitations described herein, as well as any of the additional or optional ingredients, components, steps, or limitations described herein.
To introduce the composition of the components constituting the external structuring system and the liquid detergent composition, respectively, of the present invention:
12-hydroxy-octadecanoic acid triglyceride
The 12-hydroxy-octadecanoic acid triglyceride disclosed by the invention is a main component of hydrogenated castor oil.
The castor oil is triglyceride of fatty acid, is present in the seeds of castor oil, the content is 35% -57%, it is prepared by squeezing or solvent extraction. Castor oil contains about 70% of the triglycerides of ricinoleic acid (12-hydroxy-9-cis-octadecenoic acid) in 90% of its fatty acid chains. By controlling the hydrogenation process conditions, the castor oil can be completely hydrogenated to form hydrogenated castor oil. About 70% of hydrogenated castor oil is therefore 12-hydroxyoctadecanoic acid triglyceride (i.e. 12-hydroxy-octadecanoic acid triglyceride).
The invention discloses an external structuring system composition for liquid detergents, wherein the composition comprises, in weight percent of the total composition:
a) 0.01-5% 12-hydroxy-octadecanoic acid triglyceride, preferably 0.1-2%;
b)0.01 to 5 percent of alkyl aryl sulfonic acid solubilizer, wherein the carbon atom number of each alkane chain in the alkyl aryl sulfonic acid solubilizer is less than 5, preferably 0.1 to 2 percent;
c)5 to 60 percent of surfactant, wherein the surfactant is one or a mixture of more of anionic surfactant, nonionic surfactant and zwitterionic surfactant;
d) 0.01-0.5% of pH stabilizer selected from one or more of citric acid, succinic acid, benzoic acid, gallic acid, boric acid and alkali metal salt and organic amine salt mixture thereof;
e) 90% -95.0% of water.
The preparation method can be expressed as follows:
the preparation process of the external structured system comprises four steps:
A) under stirring, sequentially adding a surfactant, alkali and an alkyl aryl sulfonic acid solubilizer into a reaction kettle, and adjusting the pH of the mixture in the reaction kettle to 6.0-10, preferably 7-8.5 by using a pH regulator;
B) then heating to 80-95 ℃, preferably 90-95 ℃, adding 12-hydroxy-octadecanoic acid triglyceride, and stirring at the temperature until all 12-hydroxy-octadecanoic acid triglyceride is completely emulsified;
C) then rapidly cooling the mixture to 55-80 ℃, and keeping the temperature for 5-300 minutes, preferably 60-120 minutes;
D) finally, slowly reducing the temperature to be lower than 40 ℃, preferably room temperature.
Step A) is the preparation of a suitable surfactant emulsifier solution. It is well known in the art that anionic surfactants have excellent emulsifying power for fats and oils, and thus, a higher content of anionic surfactant enables sufficient emulsification of 12-hydroxy-octadecanoic acid triglyceride. Since the melting point of 12-hydroxy-octadecanoic acid triglyceride is above 85 ℃;
the step B) mainly realizes the melting of the 12-hydroxy-octadecanoic acid triglyceride and the emulsification under the action of the surfactant. When the temperature drops below the melting point, e.g. below 80 ℃, 12-hydroxy-octadecanoic acid triglyceride will precipitate again.
Under the conditions described in step C), the 12-hydroxy-octadecanoic acid triglyceride will crystallize in filamentous form, with lengths ranging from a few microns to a few tens of microns, and diameters typically of a few tens of nanometers.
Rheological yield stress
The composition exhibits a solid-like relative quiescent behavior when the external force is less than a threshold value, and a liquid-like flow behavior when the external force is greater than a threshold value, which is the rheological yield stress of the composition. The invention relates to a composition with rheological yield stress passing through Herschel-Bulkle by a rheometeryThe method is obtained by fitting calculation, and the composition with certain rheological yield stress can stably suspend suspended matters in the system, so that the phenomena of layering, suspended matter sedimentation or downward suspension of the system can be avoided.
Stability test
As is well known in the art, liquid detergent stability is a very important indicator, including storage appearance stability, freeze-thaw cycle intrinsic stability.
First, in the case of storage at high or low temperatures for a long period of time and under the condition of an ever-severe change in storage temperature, the surfactant, fatty acid, auxiliary agent, salt, and the like in the composition cause phenomena such as phase separation, delamination, precipitation, flocculation, suspended particles, and the like, and even unpredictable chemical changes, so that the composition cannot be restored to its original state even when stored at room temperature, thereby causing a phenomenon of instability of the composition due to storage conditions, i.e., storage appearance stability.
In general, the reasons for the storage appearance stability problem are:
firstly, the composition is not proper in proportion and easy to gel; ② easily decomposed substances exist in the composition; ③ reactive species, such as both anionic and cationic surfactants or polymers, are present in the composition. In general, storage appearance stability testing includes: high temperature stability, low temperature stability, freeze-thaw cycle stability, normal temperature stability, and the like.

The use of optical brighteners in liquid detergents is well known in the art and commercially available optical brighteners are abundant. Optical brighteners are present in the form of their alkali metal salts (mostly sodium salts). Preferred optical brighteners include, but are not limited to: distyrylbiphenyl compounds. A suitable example is 4,4' -bis (2-sodium sulfonate styryl) biphenyl, such as the product of the BASF company under the CBS-X brand. The fluorescent whitening agents are used in amounts of 0.01% to 2% by weight, preferably 0.01% to 0.1% of the total composition.

Solvent(s)
Since the high concentration surfactant mixture is very easily gelled when it is in contact with water, and thus becomes very difficult to dissolve, the decontamination effect cannot be achieved. That is, in practical use, when a surfactant mixture of high concentration is in contact with water, it forms a semisolid gel which is not dissolved for a long time, and on the one hand, it does not reach the expected cleaning power, on the other hand, it stains clothes, and causes significant detergent residue. In addition, in order to meet the requirements of the process production and improve the production efficiency, a certain amount of solvent is generally added to ensure that the composition can be quickly mixed. As is well known in the art, the most common solvent is water, and in addition to this, a water-miscible organic solvent may be selected. Such organic solvents include lower alcohols, polyols, ethers, polyethers, alkylamines, fatty amines, alkyl (or ester) amides, mono-or di-substituted N-alkyl substituted derivatives, alkyl (or ester) carboxylic acids, lower alkyl esters, ketones, aldehydes, polyols, and glycerol esters.
In the liquid detergent, the solvent is selected from one or more of water, a polyalcohol solvent and an alcohol ether solvent, and is preferably selected from one or more of water, glycerol, propylene glycol and ethanol.
