Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a liquid bubble solution
for producing light bubbles and, more particularly, to such a
liquid bubble solution adapted to produce bubbles that provide
illumination when viewed in the dark and under an external source
of invisible ultraviolet or infrared radiation.
[0002] A known liquid bubble solution for producing black light
bubbles is composed of 75%.about.90% surface active agent and
10%.about.25% fluorescent agent, and adapted to provide
illumination of the bubbles when viewed in the dark and under an
external source of invisible ultraviolet or infrared radiation.
This composition of liquid bubble solution has numerous drawbacks
as outlined hereinafter:
[0003] 1. High manufacturing cost because of high concentration of
fluorescence agent.
[0004] 2. Low bubble producing rate because of low surface tension
due to high concentration of fluorescence agent.
[0005] 3. Low luminous effect. Because of low surface tension,
fluorescent light is evenly distributed in the bubbles, and the
periphery of each bubble is less bright.
[0006] 4. High contamination risk. Because a particular pigment
dispersion is added to the latex-like liquid bubble solution for
producing a particular color of bubble, a color stain is left on
the clothes, floor, or any object touching the liquid bubble
solution.
SUMMARY OF THE INVENTION
[0007] The present invention provides a liquid bubble solution,
which eliminates the aforesaid drawbacks. The liquid bubble
solution of the present invention achieves the following
advantages:
[0008] 1. Low manufacturing cost because of low concentration
(1%.about.6%) of fluorescent brightening agent.
[0009] 2. High bubble producing rate because low concentration of
fluorescent brightening agent produces less effect to surface
tension of bubbles.
[0010] 3. High luminous effect. Because of high surface tension,
fluorescent light is concentrated on the periphery of each produced
bubble.
[0011] 4. Low contamination risk. Because the liquid bubble
solution is maintained transparent or semitransparent when added
with a particular dye, contamination on the clothes, floor, or any
object touching the bubbles is insignificant.
[0012] 5. Wide range of working temperature. The liquid bubble
solution contains 2% glycerin, which produces a wetting effect to
help dispersion of surface active agent and dye
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] A liquid bubble solution in accordance with the present
invention comprises about 67%.about.89% water, 8%.about.25% surface
active agent, 2% glycerin, and 1%.about.6% fluorescent brightening
agent. The water used is well sterilized. The surface active agent
used is same as that used in regular liquid bubble solutions, and
mainly comprised of liquid soap. Glycerin produces wetting effect
to help dispersion of surface active agent, and to prevent surface
active agent from forming a gel, so as to widen the range of
working temperature.
[0014] The aforesaid fluorescent brightening agent is a liquid of
light brown color obtained from Diamino-Stilbene Disulphonic Acid
Derivatives. The ions of the fluorescent brightening agent are
anions. The fluorescent brightening agent has the following
properties:
1 Specific gravity: 1.1.about.1.25 under 20.degree. C. PH value:
7.about.9 under 20.degree. C. Freezing point: 4.degree. C.
approximately Boiling point 103.degree. C. approximately
[0015] Further, the fluorescent brightening agent is highly stable
and not reactive, neither inflammable nor explosive. When diluted
with water, the fluorescent brightening agent is non-toxic, and not
irritating to skin.
[0016] A liquid bubble solution made subject to the aforesaid
composition has a transparent to semitransparent color that
produces fluorescence light of blue to purple color when viewed in
the dark and under an external source of invisible ultraviolet or
infrared radiation. Because the bubbles have high surface tension,
produced fluorescent light is concentrated on the periphery of the
bubbles. Further, 0.2%.about.0.8% viscosity index improver may be
added to the solution to increase its viscosity, so as to improve
bubble formation rate.
[0017] In order to produce a particular color, a particular color
dye may be added to the liquid bubble solution at the ratio of
5%.about.20% dye with 80%.about.95% liquid bubble solution. The dye
used is a liquid pigment. The use of glycerin helps dispersion of
particles of the dye in the liquid bubble solution. When mixed with
the dye, the liquid bubble solution has the form of a transparent
to semitransparent liquid that produces a particular color of
fluorescent light when viewed in the dark and under an external
source of invisible ultraviolet or infrared radiation. Further,
because the liquid bubble solution is a transparent to
semitransparent liquid, it leaves insignificant stain on the
object, which touches the liquid bubble solution.
[0018] Although a particular embodiment of the invention has been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
