Description
Technical Field
The invention relates to the field of daily chemical washing products, in particular to a softener composition with a synergistic softening function and a preparation method thereof.
Background
The fabric softener has the functions of softening, fluffing, antistatic and the like. Among them, softness is one of the most important functions of fabric softeners, and this index is critical to the performance evaluation of commercial softeners. The main raw materials used in the common softener are double-chain cationic surfactants, and the surfactants can be adsorbed on the fiber surface through electrostatic action to play a role in softening fabrics to a certain extent, but the surfactants are insufficient for meeting the requirements of consumers on the softening performance of the product. Thus, a softening aid is typically added to the formulation to further enhance softness, smoothness and fluffiness. The softening auxiliary agent commonly used in the softener is an organosilicon softening agent. The organosilicon softener mainly comprises amino silicone oil and polyether silicone oil. The amino silicone oil softening auxiliary agent is easy to generate azo chromophore because of the amino and active hydrogen atoms on the side bonds, thereby causing the fabric to generate yellowing phenomenon. Polyether silicone oil introduces polyether chains with stronger hydrophilicity on organosilicon molecules, so that the hydrophilicity of the organosilicon is improved, but the softness is poor.
For example, chinese patent CN 109082887B adopts amino silicone oil and polyether silicone oil as softening aids, and simultaneously uses 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride to form a bridge reaction with amino silicone oil molecules to reduce fabric color change. For another example, chinese patent CN 111636201a adopts a combination of ethyl dipalmitate-based hydroxyethyl ammonium methyl sulfate and a modified silicone softener, which is an amino modified silicone polyether copolymer, to reduce the rough hand feeling of the fabric surface fibers caused by abrasion, so that the treated fabric is soft, fluffy and elastic. For another example, chinese patent CN 106835698B combines cationic starch with quaternary ammonium salt active, and the fabric softening effect is better than that of quaternary ammonium salt alone. For another example, chinese patent CN 104586649A uses cocamidopropyl PG-dimethyl ammonium chloride phosphate for a technique for preparing a water-free skin and hair cleaning care solution. For another example, chinese patent CN 106550960A uses cocamidopropyl PG-dimethyl ammonium chloride phosphate as a preparation technology for a household disinfectant.
The invention aims to solve the technical problems existing in the prior products and provides a softener composition with excellent softening function.

a. Premixing: preheating the cationic surfactant, the emulsion stabilizer and the softening auxiliary agent A to 58-63 ℃, stirring and dissolving uniformly for standby.
B. configuration: adding deionized water and an antifreeze agent into a preparation pot, and heating to 50-55 ℃ while stirring;
c. Adding the premix into a preparation pot while stirring, maintaining the temperature at 50-55deg.C, and stirring to uniformity;

TABLE 2
Test example: softness Performance test
Sensory touch evaluation test
1. Towel pretreatment: pure cotton white towel of the same model and batch with the specification of 70cm multiplied by 30cm is circularly washed for 10 times by using standard washing powder and naturally dried.
2. And (3) rinsing the softener: randomly taking 3 pieces of pretreated towels, adding 10L of tap water, adding 5g of softener, mechanically washing for 5min, dehydrating and naturally airing.
3. The experimental conditions for sensory touch evaluation were as follows:
experimental environment: the ambient temperature is (20+/-2) DEG C, and the relative humidity is (65+/-5);
Experimenters and scores: 7 subjects were selected for this experiment and were trained prior to sensory evaluation. The subjects performed a softness blind test on each sample and scored and averaged. The purified cotton white towel treated only by pretreatment is defined as the 1 st score stiff reference, the towel treated by the commercial concentrated softener (gold spinning high-energy clothes protection essence white peach+moguistox) is used as the 3 rd score reference, the brand new towel is used as the 5 th score softness reference, namely, the higher the score is, the softer is represented.
The test results were as follows:
As shown in fig. 1, from the evaluation results of the sensory touch softness, the comparison of comparative example 1 and example 1, and example 2 shows that the softness of the towel of the sample is significantly improved with the increase of the addition amount of the bionic phospholipid oleamide propyl PG-dimethyl ammonium chloride phosphate. Comparison of comparative example 1 and example 3 shows that cocoamidopropyl PG-dimethyl ammonium chloride phosphate also has obvious improvement on softness of the sample towel, which proves that the bionic phospholipid can improve the softening effect of the softener. In addition, example 4, example 5, example 6 had higher softness scores than the test towels of comparative example 1, comparative example 2, comparative example 3, comparative example 4 and example 1, and example 2 thus demonstrated that the softness effect of the combination of oleamide propyl PG-dimethyl ammonium chloride phosphate and glycerol stearate was better than that of either oleamide propyl PG-dimethyl ammonium chloride phosphate or glycerol stearate alone. Meanwhile, the softness score of the sample towel in the example 7 is higher than that in the example 3, which shows that the softness effect brought by compounding cocamidopropyl PG-dimethyl ammonium chloride phosphate and glycerol stearate is better than that of single cocamidopropyl PG-dimethyl ammonium chloride phosphate.
The data of FIG. 1 also shows that example 5, which contains 0.5% oleamide propyl PG-dimethylammonium chloride phosphate and 0.5% glycerol stearate, has a significantly higher softness score than example 2, which contains 1% oleamide propyl PG-dimethylammonium chloride phosphate. Meanwhile, example 4, which contained 0.5% oleamide propyl PG-dimethylammonium chloride phosphate and 0.15% glycerol stearate, also had a higher softness score than example 2, which contained 1% oleamide propyl PG-dimethylammonium chloride phosphate. Therefore, the effect of obviously synergizing the softening function of the softener by compounding the oleamide propyl PG-dimethyl ammonium chloride phosphate and the glyceride stearate is further shown.
