Control Paper
Product Description
The Control Paper does not contain any added chemicals, and is simply designed to act as the control in taste test experiments.
Instructions:
1.Remove one strip of Control Paper from the vial.
2.Stick out your tongue, and place the strip on your tongue.
3.The strip is tasteless, and thus should not stimulate a reaction.
Note: The SDS for each taste test paper lists the ingredients. The concentration of ingredients is usually so small, it is less than what would be considered hazardous. Aside from these small quantities, the cellulose paper is the only other ingredient. In addition, the proper use of each taste test is to touch the strip to the tongue. These taste strips have been used safely in classrooms for decades.
The manufacturing facility where the PTC paper is produced (Cottonwood, AZ) is a typical manufacturing site. We don’t manufacture nuts, gluten or other products usually associated with allergy concerns. Please note, however, that the facility is not certified or considered an allergy-friendly manufacturing facility. In addition, the raw materials used in producing the taste test papers are not procured in any special fashion. We have no assurance that they were produced in an allergy-free environment.
Despite the above information, if you have a concern about a possible allergic reaction, perhaps it would be best to abstain from the activity.

PTC TEST PAPER
Product Description
PTC (pheylthiocarbamide) taste test paper test for the genetically controlled ability to taste this substance. This will allow for the development of a Pedigree for an individual. PTC can taste bland, bitter or even vile depending upon how sensitive your taste buds are to this chemical. The bitter taste detected by some individuals, and its intensity, depends upon a homozygous dominant or heterozygous condition in the individuals tested.
PTC Taste Test Paper is perfectly safe to use. Any possible toxicity of PTC would be in grams per kilogram of body weight, which is millions of times greater than anything which would be found in our taste test strips. Phenylthiocarbamide (PTC) is present at only 3-5 micrograms per strip. At this level, the compound is negligible and harmless.
Instructions:
1. Remove a PTC taste test paper from the vial.
2. Stick out your tongue, and place the strip on your tongue.
3. There are three basic results: bland, bitter, or vile.
