Description of key information
Skin irritation - Mean value of three test data gave a value of 78.3% mean issue viability in the EpiDerm skin test (OECD 439).
Accoridng to the test protocol, a value of >50% predicts Non-Irritant under GHS classification.
Human patch test data also indicated non-irritant at 10% in water over 72 hours.
Eye irritation - Under the conditions of the Matek EpiOcular test, the results indicate that the Colaliquid DC-5 100% Active test article, at 100%, has a non-irritating/minimally irritating classification. Non-Irritant under GHS classification.
The HET-CAM hen's egg test also confirmed non-irritant.

- Guideline:
- other: MatTek Corporation Epiocular ia vitro toxicity testing systern.
- Principles of method if other than guideline:
- "MatTek's patented Epiocular comeal Model consists of normal, human-derived epidermal keratinocytes which have been cultured to form a stratified, squarnous epithelium similm to that found in the cornsa. The epidermal cells, which are cultured on specially prepared cell culture inserts using serum free medium, differentiate to form a multilayered structure which closely parallelsthecornealepithelium..."This system"...providesapredictive,morphologically relevant in vitro means to assess ocular irritancy."
EpiOcular, when used with the recommended cell metabolism assay, can quickly provide toxicological profiles. The procedure utilizes a water-soluble, yellow, tetrazolium salt (MTT {3-[4,5-dimethylthiazol-2-yll-2,5-diphenyl-tetrazolium bromide])" which is reduced by succinate dehydrogenase in the mitochondria of viable cells to a purple, insoluble formazan derivative.Substances which damage this mitochondrial enzyme inhibit the reduction of the tehazolium salt.The amount of MTT reduced by a culture is therefore proportional to the number of viable cells - GLP compliance:
- yes

- human
- Vehicle:
- water

Therefore, as per MatTek's protocolo the test article was diluted to 20% in distilled watsr.

- The test or.reference article, at a dosage of three-tenths of one milliliter (0.3 ml) of a liquid or three-tenths of one gram (0.3 g) of a solid was then administered to each of four (4) CAM's. Twenty seconds later, the test or control article was rinsed from each CAM with five (5) milliliters of physiological saline. All CAM's •were observed immediately prior to test article administration and at 30 seconds. two (2) and five (5) minutes after exposure to the test article. The reactions of the CAM, the blood vessels, including the capillaries, and the albumin were examined and scored for irritant effects.
The numerical, time dependent scores were totaled for each CAM. Each reaction type can be recorded only once for each CAM, therefore the maximum score per CAM is 32. The mean score was determined for all CAM's similarly tested.
Two reference materials were used as a comparison to the ColaMoist 200 (5% active aqueous sample).
These were (1) Johnson's baby shampoo and (2) Prell shampoo (no data on pH of this material). Both reference materials are commercially available shampoos that have a similar % active ingredient level to the ColaMoist 200 (5% active) material - Details on study design:
- Fresh, fertile, White Leghorn eggs were obtained from Avian Services in Frenchtown, New Jersey. They were stored at this facility for up to seven (7) days, at 13° C, before being incubated. For incubation the eggs were placed, on their sides, in a Kuhl incubator. The incubator is such that the eggs are automatically rotated once every hour. The temperature was controlled at 99° F (± I 0 with a relative humidity of 60 - 70% for the ten (I0) days of incubation. On day eight (8) the eggs were turned so that the acutely angled end faced down.
On day ten ( I 0) each egg was removed from the incubator and placed in a Plexiglas work enclosure. This enclosure had been preheated and humidified so that its environment approached that of the incubator. A cut was made in the Iaeger end of each egg, where the air sack is located. A Dremel11 Moto-Flex Tool (model 232-5) equipped with a Dremel-,; Cut-Off Wheel (No. 409) was used to make each cut. Forceps were then used to remove the shell down to the shell
membranc junction. The inner egg membrane was then hydrated with a warm, phyiological saline solution. The saline was removed after a two (2) to five (5) minute exposure. Utilizing pointed forceps, the inner egg membrane was then carefully removed to reveal the CAM.
The test or.reference article, at a dosage of three-tenths of one milliliter (0.3 ml) of a liquid or three-tenths of one gram (0.3 g) of a solid was then administered to each of four (4) CAM's. Twenty seconds later, the test or control article was rinsed from each CAM with five (5) milliliters of physiological saline. All CAM's •were observed immediately prior to test article administration and at 30 seconds. two (2) and five (5) minutes after exposure to the test article. The reactions of the CAM, the blood vessels, including the capillaries, and the albumin were examined and scored for irritant effects. - Irritation parameter:

A Molecular Devices SpectraMax M5 Microplate Reader was used to determine the absorbance of each extract at 570nm. With the absorbance of the negative control (distilled water) defined as 100%, the percent absorbencies of the test article were determined. The
percentages listed below directly correlate with the cell metabolism in the EpiOcular samples.
(20% - 4 hrs.) - % viability = 39, % inhibition = 61
(20% - 1 hr.) - % viability = 61, % inhibition = 39
(20% - 20 mins.) - % viability = 75, % inhibition = 25
When possible, using a semilog scalg the percent viabilities for the article were plotted on the linear y axis versus the dosing time on the log x axis. By interpolation, the time at which the percent viability would be 50% was determined (ET-50).
As a general guideline (provided by MatTek) the following equation can be used to estimate the rabbit Draize eye score:
Draize : 4.7 4 + 101.7/(ET-50)^0.5
Based on the literature (Kay, J.H. and Calan&a J.C., "lnterpretation of eye irritation tests,"J Soc. Cosmetic Chem., 13, 281-289 (1962)), the ocular initancy estimated potential has been categorized by MatTek into the following groups, based on the Draize score:
Under the conditions of this test, the Colaliquid DC-5 100% Active test article, at 20%, elicited in vitro results which indicate that its ET-50 is 122.1 minutes. Therefore, at 100%, the test article's estimated Draize ocular iritation score is approximately 4.5 with a "minimally irritating" irritancy classification.
Previous studies have shown that the CAM of the hen's egg is more sensitive to lquid irritants than is the rabbit eye. Therefore, 50% dilutions of the liquid test and reference articles were used.
Historical in-vivo testing on Johnson's reference product has shown this material to be 'moderatley irritating' eliciting scores approaching 10 at 24 hours when dosed at 100% and tested using the draize ocular irritation method.
The Prell reference product under the same in-vivo Draize testing has given scores approaching 30 at 24 hours when dosed at 100%.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not irritating)
