Description
Technical Field
The invention belongs to the technical field of laundry detergent, and relates to a softening laundry detergent with obvious softening effect.
Background
The active ingredients of the liquid laundry detergent are mainly surfactants, and the structure of the liquid laundry detergent comprises a hydrophilic end and an oleophilic end, wherein the oleophilic end is combined with a stain, and then the stain is separated from a fabric through physical movement (such as hand rubbing and machine movement). Meanwhile, the surfactant reduces the tension of water, so that the water can reach the surface of the fabric, and the active ingredients play a role.
In daily life, people find that the washing times of clothes are slightly more, the clothes become hard, the hand feeling is poor, and the clothes become old and even break quickly. This is mainly because the fabric is now treated with a large amount of softener at the time of shipment, and the softener on the surface is gradually washed away during the washing process, so that the hand feel is deteriorated. After the softener is washed away, the friction force between the clothes fibers is increased, the fabrics are easily damaged, the clothes are not durable, and the clothes are easily worn out and damaged, so that great waste is caused. In view of the fact that the current laundry softener market is not popular, it is necessary to add a small amount of softener to the laundry detergent to improve the feel of the laundry after washing.
The addition of softening agents in laundry detergents requires solving several technical problems:
(1) Compatibility: the softening agent itself tends to be cationic and needs to be compatible with anionic surfactant based laundry detergent systems. Thus, the compatibility problem of the cationic softener and the anionic-based laundry detergent system is solved.
(2) Adsorption: a part of softening agent can be adsorbed on the surface of the fabric after washing, so that the softening effect can be achieved
(3) Detergency: the softener is adsorbed on the surface of the fabric and cannot influence the detergency of the laundry detergent.
Disclosure of Invention

The structural formula of the softening additive comprising the double quaternary ammonium salt modified polysiloxane QSQ is shown as a chemical formula (I).
Wherein Q is a hydrophilic cationic quaternary ammonium salt segment (as shown in a chemical formula (I)), and can be an alkyl imidazoline quaternary ammonium salt structure or other hydrophilic cationic quaternary ammonium salt structures. R1 is selected from one or two of saturated or unsaturated aliphatic alkyl (such as oleic acid) of C8-C22 or saturated or unsaturated aliphatic alkyl (such as oleic acid amide) containing amide groups of C8-C22; r2 is one or both of C2-C5 alkyl or C2-C5 polyetheralkyl (e.g. -CH) 2 -CH 2 (-), n is 10-5000 degrees of polymerization.
Currently, there are several major classes of softening agents on the market: one type is a long carbon chain cationic quaternary ammonium salt softener. The common cationic quaternary ammonium salt softener is difficult to be compatible with a washing liquid system with more anionic surfactant because of stronger cationic property, and the system is unstable and easy to whiten and precipitate. Therefore, the quaternary ammonium salt of imidazoline (represented by the chemical formula (II), hereinafter referred to as "Q") is mainly a quaternary ammonium salt of imidazoline having relatively good hydrophilicity and relatively weak cationicity.
However, the better hydrophilicity and weaker cationicity can affect the adsorption of the cationic quaternary ammonium salt softener on the surface of the fabric. And the common quaternary ammonium salt product has better softening and fluffing effects on cotton products, but has common slip effect on terylene or other chemical fibers. Meanwhile, the alkyl chain of the imidazoline type quaternary ammonium salt is also a grease source, the detergency is influenced after adsorption, and the imidazoline type quaternary ammonium salt also has the problem of yellowing fabrics, so that the imidazoline type quaternary ammonium salt is only used in a small amount. The other class is silicone softeners, including amino-modified silicone oils (e.g., formula (III)) and amino polyether-modified silicone oils (ternary silicone oils, e.g., formula (IV)). The amino modified silicone oil softener has poor hydrophilicity, can be compatible with a laundry liquid system after emulsification, has poor stability, is easy to cause problems of silicon spots, fabric yellowing and the like, also influences the detergency of the laundry liquid, and cannot be used in laundry liquid products. The amino polyether modified silicone oil (ternary polymerization silicone oil) has better hydrophilicity and weaker partial cation property because of containing polyether groups, and can also be used for a laundry detergent system. However, the hydrophilic property is good, the cationic property is weak, the adsorption on the surface of the fabric is less in the washing process, the softening effect is not obvious, the cost is high, and the large-scale popularization and application are not possible.
Aiming at the problems, a novel softener double quaternary ammonium salt modified polysiloxane QSQ is developed, and a novel softening laundry detergent is developed on the basis of the softener, so that the novel softener can be compatible with anionic laundry detergent; the washing agent has good adsorptivity and obvious softening effect after washing; meanwhile, the detergency of the liquid laundry detergent is not affected.
The structural formula of the double quaternary ammonium salt modified polysiloxane QSQ is shown as a chemical formula (I).
The structural formula of the novel softener double quaternary ammonium salt modified polysiloxane QSQ is shown in a chemical formula (I). Hydrophilic imidazoline cationic quaternary ammonium salt (Q) is arranged at two ends of the chain segment, and polydimethylsiloxane chain segment (S) is arranged in the middle. The QSQ structure has double-cation and hydrophilic imidazoline quaternary ammonium salt structures at two ends of the chain segment, so that on one hand, the adsorption efficiency of the softener on the surface of the fabric is greatly increased, and the fabric has better softness and fluffiness; meanwhile, because of the hydrophilicity and compatibility of the imidazoline groups, the laundry detergent system is relatively easy to disperse in anions. On the other hand, the high molecular weight organosilicon chain segment brings good slip and softening effects to fabrics, especially polyester. While having less impact on detergency.
Wherein Q is a hydrophilic cationic quaternary ammonium salt segment (as shown in a chemical formula (I)), and can be an alkyl imidazoline quaternary ammonium salt structure or other hydrophilic cationic quaternary ammonium salt structures. Wherein R1 is selected from one or two of saturated or unsaturated aliphatic alkyl of C8-C22 and saturated or unsaturated aliphatic alkyl containing amide groups of C8-C22; r2 is one or two of C2-C5 alkyl and C2-C5 polyether alkyl; n is 10-5000 polymerization degree;
the synthesis of the novel softener double quaternary ammonium salt modified polysiloxane (QSQ) is that C8-C22 fatty acid, fatty amine, polyether and the like react at high temperature to synthesize reactive C8-C22 fatty alkyl imidazoline alkoxy, and then the reactive C8-C22 fatty alkyl imidazoline alkoxy reacts with reactive organosilicon intermediates with hydroxyl (-OH) or other active groups at the tail end at high temperature, vacuumizing and in the presence of a catalyst to synthesize the softener double quaternary ammonium salt modified polysiloxane.
Even if the novel biscationic quaternary ammonium salt softener QSQ has good hydrophilicity, the novel biscationic quaternary ammonium salt softener QSQ is directly added into an anionic laundry detergent system, the novel biscationic quaternary ammonium salt softener QSQ has the condition that anions and cations are incompatible with other cation quaternary ammonium salts, and the laundry detergent cannot keep transparency and stability for a long time. Therefore, through research and exploration, we find a suitable dispersing agent HEX, the structure of which comprises cationic alkyl quaternary ammonium salt polyoxyethylene ether (the structure of a chemical formula (five)), and one or two of polyether organosilicon dispersing agents (the structure of which is a chemical formula (six)), so that the cationic quaternary ammonium salt softening agent QSQ can be stably dispersed in a common anionic laundry detergent system in the market. Meanwhile, in the experimental process, the cationic surfactant has a synergistic effect on the adsorption of the cationic softener on the surface of the fabric.
In order to ensure the detergency of the liquid laundry detergent, a certain amount of fatty acid methyl ester polyoxyethylene ether (shown as a chemical formula (seven)) and alkyl glycoside surfactant (shown as a chemical formula (eight)) are selected in the formula besides a common anionic surfactant and a nonionic surfactant.
Based on the novel softener QSQ and the cationic dispersant HEX, according to the research results, a novel softening laundry detergent is developed, wherein the novel softening laundry detergent comprises 0.5-10% of double quaternary ammonium salt modified polysiloxane softener QSQ and 0.5-5% of cationic surfactant HEX; including but not limited to 10-60% of anionic surfactant such AS one or more of sodium fatty alcohol polyoxyethylene ether sulfate (AES), sulfonic Acid (AS), sodium alpha-alkenyl sulfonate (AOS), etc.; 1-30% of nonionic surfactant comprising one or more of fatty alcohol and fatty alcohol polyoxyethylene ether (AEO), fatty acid methyl ester polyoxyethylene ether (MEE), alkyl glycoside (APG) and other nonionic surfactants; and a proper amount of chelating agent (such as EDTA), consistency regulator, defoamer (modified organic silicon defoamer) and the like, and the stability, the softening effect and the detergency of the researched and developed softening laundry detergent are compared and characterized, so that the novel softening laundry detergent has good stability and obviously better softening effect than that of market products under the condition of keeping the detergency of national standard laundry detergent.
The synthesis of the softener double quaternary ammonium salt modified polysiloxane (QSQ) is that C8-C22 fatty acid, fatty amine, polyether and the like react at high temperature to synthesize C8-C22 aliphatic alkoxy quaternary ammonium salt with reactivity, and then the reactive quaternary ammonium salt and an active organosilicon intermediate with hydroxyl (-OH) at the tail end react at high temperature in the presence of a catalyst under the condition of vacuumizing.
The production process of the softening laundry detergent comprises the following steps: injecting water into a pot, heating to 80 ℃, then sequentially adding an anionic surfactant, a nonionic surfactant, a cationic surfactant and novel softener dialkoxy polysiloxane (QSQ), adding a dispersing agent (HEX) into the pot, fully and uniformly stirring, cooling to 40 ℃, adding the rest materials into the pot, and uniformly stirring to obtain the finished product.
Table 1: example 1-example 7 and comparative example 1:
softening effect: the experiment adopts a general hand feeling evaluation method, and the specific experimental process is as follows:
a pure cotton white towel without post-treatment (no softening treatment after the pretreatment) was used as the test fabric. The test sample was the laundry detergent of comparative example 1 and each example.
In the experiment, the towels used were first weighed (essentially uniform for each weight). Placing into a testing washing machine at room temperature, setting a standard washing program (equipment: hai Xin full-automatic mini washing machine, washing time: standard washing for 36 minutes, temperature: room temperature), adding a test sample (0.2% concentration, 1/3 in examples 4-5), washing, and drying at 105 ℃ to be tested. The towel is folded to be the same in thickness and the same in direction during testing, the test sample and the blank sample are in comparison, 5 people with certain experience and sensitive hand feeling are required to evaluate the towel during testing, the result is statistically compared by a scoring method, the score is divided into 5 parts with the highest score and 1 part with the lowest score, and the higher the score is, the better the softness is indicated.
Experimental results: example 2 shows turbidity, examples 2-5 are clear and transparent under heat-resistant and cold-resistant conditions at different temperatures, which shows that the compatibility is poor when the novel softener QSQ is singly added into the laundry detergent mainly containing anionic surfactant; after the cationic dispersant HEX is added, the stability of the novel softener QSQ in a laundry detergent system mainly containing anionic surfactants is obviously improved.
Table 2: example 1-example 7 and comparative example 1 stability comparison experiments in laundry detergent systems:

experimental results:
1) From example 2 and comparative example 1, the addition of the cationic dispersant HEX has limited improvement in softening effect without the addition of the softener QSQ.
2) In comparison with examples 3 to 5 and comparative example 1, when the softener QSQ was added, the softening effect was significantly improved as compared with that without addition, and the softening effect was also improved continuously with the increase of the addition amount; in contrast, in examples 4,6 and 7, the softening effect was also enhanced with the increase of the cationic dispersant HEX compared with comparative example 1, showing that HEX has a synergistic effect on the softening effect of the novel softener QSQ.
