Abstract
ABSTRACT A non-toxic dye in an aerosol container to be used for protection against an assailant is disclosed. The dye is an irritant to skin and eyes and is also a semi-permanent marking dye which is intended to aid in the identification of the assailant by police.
Description
This invention relates to a personal protection and criminal identification device. ~n aerosol spray container of non-toxic dye is designed to help individuals defend themselves from assailants while marking the criminal with a dye that will later help identify the criminal to police and others.
In today's society, people are often frightened to walk alone, for fear of attack. Various methods of self-protection have been tried. For example, weapons can be carried, or ordinary objects such as keys can be used as temporary weapons. While carrying weapons can be illegal, the most important problem with this method is the possibility that if the victim is not strong enough to stay in control of the weapon, it can be taken away and used against them by the assailant.
Noise makers are also available which emit a loud "screech". These devices are intended to call attention to the situation. This is of little value if there is no one around to hear the noise, or if bystanders do not recognize the noise as a distress signal, or if they ignore the noise.
Chemical irritants such as Mace (trademark), like the noise-making products, do not require great strength, and are sometimes used by individuals to defend themselves when they are attacked. Such products can be dangerous, however, and there is also the potential for the mace to be taken from the victim and turned against him or her.

It is an object of the invention to provide a safe substitute for mace and the like, which will also serve the purpose of marking an assailant for identification purposes.
The invention does not use a toxic substance, so if it is used against the victim, it will not cause any serious damage. The spray should surprise the assailant, and when sprayed towards the face will sting the assailant~s eyes and face, since the dye is an irritant. This should in most cases provide the victim with an opportunity to escape.
At the same time, the indelible dye will mark someone for a significant period of time, possibly from three days to three weeks. This should help identify the assa~lant and make it easier for identification by the police.
Thus in accordance with the present invention there is provided a dye based on FD & C and DC dyes, which are non-toxic. The dye is in a conventional aerosol can approximately 4-1/2 inches tall (including cap) by 1-1/2 inches in diameter.
The invention i8 intended to be small enough to be carried in purses and pockets, so that it can be readily available if needed.
In the invention, the dye mixture is provided in a conventional aerosol spray canister, approximately 4-1/2 inches tall (including cap) by 1-1/2 inches in diameter. The canister is intended to be small enough to be carried in purses and pockets, so that it can be readily available if needed.
The specific formulation of the preferred dye mixture is as follows, with the percentages being by weight.
The preferred total fill weight per unit is 50 grams.
FD&C Green #15794, supplied by Tricon 3.14%
Ariavit* Green S #312524, supplied by Charles Tennant 1.62%
Water (deionized), supplied by Crystal Springs 85.57%
Triton X-100*, supplied by Rohm & Haas 0.10%
Formaldehyde, supplied by Ashland Chemicals 0-05%
Hydrocarbon propellant (A-70), supplied by Stanchem - CIL 9.52%
=======
100.00%
An alternative formulation is as follows:
D&C Green #5 3.30%
(Alizarin* Green Cyanine J) D&C Green #3 1.70%
(Fast Green #3) Water (deionized) 89.85%
Triton X-100* 0.10%
Formaldehyde 0.05%
Hydrocarbon propellant (A-46)5.00%
100.00%
The concentrate for the alternative formulation has the following specifications at 25 degrees C:
pH: 7.0 Specific Gravity: 0.9731 Colour: Green Solid: 5.37 * Trademarks The specification of the finished product according to the alternative formulation, i.e. after dilution with the deionized water, is as follows, again at 25 degrees C:
Specific Gravity: 0.9616 Vapour Pressure: 45 psig Spray Rate: 1.6 mg/sec Flame Extension: Nil The specifications for the preferred formulation are not presently available, but are presumed to be similar.
The canister is a conventional one supplied by Lechner GMBH, West Germany, and in the preferred embodiment is 35 x 97mm, Microflex ttrademark) lined. The valve is supplied by Precision Valve Canada Ltd, and has the following specifications:
Stem - .024 Spring - stainless steel Gasket - neoprene Housing - .080 bonded Cup - conical, open top & bottom, undimpled, bonded, lip P/E sleeve Dip tube - 96mm The actuator is a .016 MB Aqua Delta (trademark), also supplied by Precision Valve Canada Ltd.
The dyes used in the formulation are FD & C approved for internal and external use in drug and cosmetic preparations. The small amount of detergent used in the formulation is a mild irritant, but it is safe. The detergent creates a 1/2" buildup which has a strong psychological impact on the assailant, and which makes the composition difficult to 2~3949 remove immediately. The dye therefore has a greater length of time to work into the skin, producing a mark which is extremely difficult to remove.
It will be appreciated that the above description relates to the preferred embodiment by way of example only.
Many variations on the invention will be obvious to those knowledgeable in the field, and such obvious variations are within the scope of the invention as described and claimed, whether or not expressly described.
For example, it should be appreciated that the above compositions could be varied substantially by those knowledgeable in the field.
