Description

Colorful deep sea crystal salt bacteriostatic decontaminating fragrance-retaining washing gel bead and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemicals, in particular to a colorful deep sea crystal salt bacteriostatic decontaminating fragrance-retaining washing gel bead and a preparation method thereof.

Background

Laundry beads are household laundry detergent products which have emerged in recent years, are innovative laundry products and are increasingly subjected to the action of squints by young consumers in China. The product is a laundry product which is formed by wrapping highly concentrated laundry detergent, softener and other auxiliary agents by a water-soluble polymer film bag, and is packaged into a bead shape or a bag shape, when the product is used, one laundry detergent, softener and other auxiliary agents are directly put into a washing machine, and the laundry detergent, softener and other auxiliary agents are dissolved in water within 0.5 minute and completely dissolved within 15 minutes, so that 6-14 pieces of laundry can be washed.

In recent years, many researchers have studied the formulation of laundry beads to explore their versatility, such as stain removal, cross-color prevention, whitening, lasting fragrance, bacteriostasis, and sterilization.

Viscosity is a problem noticed by producers when producing laundry emulsions and is a criterion for laundry liquid consumers to make initial judgments on laundry emulsions. Although it is not completely correct to judge the quality of the laundry detergent by the viscosity of the laundry emulsion, the current consumption idea of people considers that the laundry detergent is fake if not viscous, the laundry detergent with high viscosity has high concentration and strong dirt-removing capability. At present, the common method for increasing the viscosity of the laundry emulsion is to add chemical raw materials such as a thickening agent, and the selection and the proportion of the thickening agent of the laundry emulsion are the problems that most manufacturers often tangle. The excellent laundry detergent can satisfy both manufacturers and consumers, and the consumers become returning customers and old customers; meanwhile, the method brings good economic benefits to enterprises and can be generalized and extracted only in the extensive market. It follows that the choice of laundry emulsion thickener is also of critical importance. In order to meet the first sensory experience of consumers, a colorful deep sea crystal salt bacteriostatic decontaminating fragrance-retaining laundry gel bead with high viscosity and a preparation method thereof are developed.

Meanwhile, the conventional laundry gel bead packaging machine manufactured by Qicheng die company Limited in Guangzhou city is mainly adopted in the production process, and the patent publication number of the laundry gel bead packaging machine is 'CN 209634778U'. The packaging machine has a novel structure, can package the laundry detergent into individual standard dosage, and is more convenient to use. However, in the actual production process, different experiments are required for different formulations and different batches of PVA water-soluble films (the experimental mode is that a small amount of produced laundry beads are kept still in a laboratory for 3 days to observe whether the laundry beads have phenomena of edge explosion, damage, softening and the like), that is, the small-batch production is required according to different formulations and different batches of PVA water-soluble films. Because current packagine machine, its structure and power are great relatively, and the station is more relatively, and it is more in the energy resource that consumes when carrying out small batch production, and the cycle of operation is long, is unfavorable for the quick adjustment of carrying on the product scheme. Therefore, the development of a colorful deep sea crystal salt bacteriostatic, decontaminating and fragrance-retaining washing gel bead with high viscosity is necessary, and simultaneously, the development of a proofing machine of the washing gel bead is necessary.

Sorbitol, glycerol and propylene glycol are used as auxiliary agents, wherein sorbitol is also used as a filling material in the invention, the water content is required to be less than 5%, too high water content can cause the condensation beads to become soft, and the coated laundry emulsion is separated out from the PVA film on the outer layer; the sodium fatty alcohol-polyoxyethylene ether sulfate (AES) and disodium ethylene diamine tetraacetate (EDTA-2 Na) are used as the surfactant, wherein the sodium fatty alcohol-polyoxyethylene ether sulfate has the effects of decontamination, emulsification and foaming; the deep sea crystal salt, isothiazolinone (cason) and Parachlorometaxylenol (PCMX) have decontamination and sterilization effects, wherein the isothiazolinone also has a preservative effect and is used as a preservative in the application.

The deep sea crystal salt has the same components as industrial salt, and the addition of the deep sea crystal salt can increase the viscosity of the laundry emulsion, so that the first sensory effect of consumers is better, and the increased viscosity is favorable for forming laundry gel beads and increasing the fullness of the laundry gel beads. Because the water content of the sorbitol is less than 5 percent, the deep sea crystal salt is mainly dissolved or diluted by using the water in the sorbitol, and can be dissolved after being stirred for 1 hour at the temperature of 45-50 ℃ during preparation.

According to the PVA high-molecular instant membrane on the outer layer of the laundry gel bead, the membrane is dissolved when meeting water, so that water cannot be directly added into the formula of the instant membrane, but the sorbitol and the fatty alcohol-polyoxyethylene ether sodium sulfate both contain a small amount of water, deep sea crystal salt is dissolved in the water, and the deep sea crystal salt is added and then dissolved in the water of the sorbitol and the fatty alcohol-polyoxyethylene ether sodium sulfate, so that the water saturation is increased, the viscosity of the laundry emulsion is also increased, and the fullness of the laundry gel bead can be increased. As the deep sea crystal salt absorbs the water in the sorbitol and the fatty alcohol-polyoxyethylene ether sodium sulfate, the water molecules lose the activity, and the water cannot permeate outwards to damage the PVA water-soluble film on the outer layer of the laundry emulsion.

The laundry gel bead has the characteristics of low foam, easiness in rinsing, bacteriostasis, decontamination, 72-hour lasting fragrance and the like, wherein the deep-sea crystal salt has a very strong bacteriostasis and sterilization effect and has the advantages of low cost, easiness in obtaining raw materials and the like; the invention avoids directly adding water in the preparation process, so as to prevent the prepared washing coagulated balls from softening on one hand, and prevent the washing emulsion in the inner layer from separating out from the film of the outer layer, thereby reducing the gram weight and ensuring the unsatisfactory plumpness of the washing coagulated balls. The proofing machine can rapidly perform proofing on products, so that the experiment of samples and the adjustment of product schemes are conveniently and rapidly realized, the response speed is higher, and the development cycle of the products is effectively shortened; meanwhile, the structure is simple, the operation is convenient, excessive debugging and preheating of equipment are not needed, and the energy consumption and the product development cost are reduced.
