Technical Field

The invention relates to the technical field of bubble liquid, in particular to safe and non-toxic bubble liquid for children and a preparation method thereof.

Background

The bubble liquid is a liquid required in the children bubble-blowing game, and can be blown into circular bubbles. Bubbles are formed by the surface tension of water, which is the mutual traction force existing in the interior of the object perpendicular to the contact surface of two adjacent parts when the object is subjected to a tensile force. The water surface has stronger attraction between water molecules than between water molecules and air, and the water molecules are adhered together. The bubble liquid "breaks" the surface tension, which reduces the surface tension to 1/3, which is the only normal condition for blowing bubbles, and the bubble disappears as soon as the bubble surface breaks as the water evaporates. While light passing through the bubble film is refracted at both the top and bottom of the film, the soap film can contain up to about 150 different layers. The messy color combinations we see are caused by unbalanced film layers. The thickest film layer reflects red light, the thinnest reflects purple light, and the middle reflects seven colors of light.

The bubble water is one of important toys of children, the safety of bubble water solution should be specially paid attention to when the bubble water is purchased, bubble water manufacturers on the market can look like cow hair, various bubble water is full of bubbles, the common defect is that bubbles are easy to break, and alkaline ingredients in the bubble water solution can corrode the skin of children.

Considering the safety problem of bubble water, the bubble water is worthy of being updated by related technicians, and under the trend that health consciousness and environmental consciousness are increasingly improved, the bubble water which is natural and environment-friendly and not easy to break can be popular with parents and children, so that the bubble water has great significance.
