- Subjects:
- One hundred sixty-six (166) subjects, 26 males and 140 females, ranging in age from 19 to 68 years were empaneled for this test.
The subjects were informed of the nature of the test, including possible adverse reactions. Written informed consent was obtained.
Additionally, the subjects were considered dependable and able to read and understand instructions. The subjects did not exhibit any physical or dermatologicaI condtion that would have precluded application of the test article. - Clinical history:
- The subjects did not exhibit any physical or dermatological condition that would have precluded application of the test article.

- Induction Phase
The Induction Phase was initiated on: June 9, 1993 (Panel No. 93081); January 30, 1995 (Panel No. 95000.); February 6, 1995 (Panel No.: 95016); March 13; 1995 (Panel No. 95032); March 22, 1995 (Panel No. 95037) and April 19, 1995 (Panel No. 95052).
A sufficient amount of the test article (approximately 0.2 mL) was placed onto a Parke-Davis ReadiBandage occlusive patch, which was applied to the back of each subject between the scapulae and waist. adjacent to the spinal mid-line.
The subjects were instructed to remove the patch 2 hours after application. Twenty-four hour rest periods followed the Tuesday and Thursday removals and 48-hour rest periods followed each Saturday removal. The site was scored by a trained examiner just prior to the next patch application. This procedure was repeated every Monday, Wednesday and Friday until nine (9) applications of the test article had been made.
Procedurally, if a subject developed a positive reaction of a 2-level erythema or greater during the Induction phase or, at the discretion of the Study Director, if the skin response warranted a change in site, the patch would be applied to a previously unpatched adjacent site for the next application.
If a 2-level reaction (or greater) occurred at the new site no further applications would be made. However, any reactive subjects would be subsequently Challenge patch tested.
Challenge Phase.
After a rest period of approximately two weeks (no applications of the test article), the Challenge patch was applied to a previously unpatched (virgin) test site. The site was scored 24 and 72-hours after application. All subjects were instructed to report any delayed skin reactivity which might have occurred after the final Challenge patch reading. When warranted, selected test subjects were; called back to the Clinic for additional examinations and scoring to determine possible increases or decreases in ChaIlenge patch reactivity.
The final Challenge patch reading was made on July 16, 1993 (Panel No. 93081); March 13, 1995 (Panel No. 95009); March 20, 1995 (Panel No. 95016); April 24, 1995 (Panel No. 95032); April 28, 1995 (Panel No. 95037) and May 31, 1995 (Panel No. 95052).

Forty-six (46/53) subjects satisfactorily completed the test procedure. Seven (7/53) subjects discontinued for personal reasons unrelated to the conduct of the study.
Panel No. 95009:
Twenty four (24/34) subjects satisfactorily completed the study. Ten (10) subjects discontinued [6 subjects (nos.23, 2,6,33, 36,37,42) discontinued for reasons unrelated to the study, 1 subject (no. 30) did not wish to patch, 3 subjects were discontinued due to violation of protocol (no. 32 had been patched with a sulfonate on a previous RIPT Panel; no. 50 had a history of sensitivity to soaps; no. 53 was unsuitable for patching)].
Panel No. 95016:
Twenty-two (22/26) subjects satisfactorily completed the study. Four (4) subjects discontinued [1 subject (no. 14 discontinued for reasons unrelated to the study, 1 subject (no. 12) was discontinued due to reaction to the patch adhesive, 2 subjects (nos. 8, 39) were discontinued due to violation of protocol-they had been patched with a sulfonate on a previous panel].
Panel No. 95032:
Sixteen (16/17) subjects satisfactorily completed the study. One (1/17) subject (no. 38) discontinued for reasons unrelated to the study.
Panel No. .9 50.37. .:
Twenty-two (22/22) subjects satisfactorily completed the study.
Panel No. 95052:
Twelve (12/14) subjects satisfactorily completed the study. Two (2/14) subjects (nos. 41 and;46) discontinued for reasons unrelated to the study.
A total of one hundred and forty-two (142/166) subjects satisfactorily completed the study between June 9, 1993 and May 31, 1995. Discontinued panellist data are shown up to the point of discontinuation, but are not used in the Results, Discussion or Conclusions sections of this final report.
Scattered, barely perceptible (+) to mild (1-level) non-specific patch test responses were observed on 10/142 test panellists (Subject nos. 24, 39, 48, 50 [Panel No. 93081 to mild (1-Ievel)]; 47 [panel No. 95009]; 15;23 [Panel No. 95016]; 44 [Panel no. 95037]; 44 and48 [Panel 95052]) during the Induction and/or Challenge phases of the study. None of these non-specific reactions was considered to be irritant or allergic in nature.
Barely-perceptible (+) to moderate (2-level) irritant/cumulative irritant patch test responses were observed on 26/142 test panellists (Subject nos. 14, 16, 19, 22, 27, 31, 35, 40 [Panel no. 93081]; 27, 39, 41, 43, 45, 48, 50, 55 [Panel no. 95009]; 2, 32, 38, 43, 44 [Panel no. 95016]; 50 [Panel
no. 95032]; 45, 48, 49 [Panel no. 95037]) and 50 [Panel no. 95052]) during the Induction and/or Challenge Phases of the study. None of these skin reactivity patterns was considered to be allergic in nature.
Skin reactivity patterns, which in the opinion of the Principal Investigator, are suggestive of allergic contact dermatitis, were observed on 8/142 test panellists (Subject nos. 11 and 47 [Panel no. 95016]; 39, 40, 46 [Panel no. 95032]; 46, 47 [Panel no. 95037]; and 40 [panel no. 95052].
Subject no. 11 (Panel No. 95016) experienced 4-level erythema at the 72-hour Challenge patch reading which was reported as an adverse event.
Any other information on results incl. tables
SUMMARY OF REACTION:
At the 72 hour challenge patch reading, the subject exhibited 4-level erythema with severe dryness, severe oedema, and mild papules in contact site. Also there was a 2 level erythema with moderate, papular reaction, spreading about 1" beyond contact site.
At the 96 hour reading, the subject exhibited 3-level erythema with moderate vesiculation on the patch site, and a severe papular reaction covering approximately 1/2 of the upper back area.
At the 168 hour reading the subject exhibited 2-level erythema with moderate dryness and a moderate papular reaction, extending beyond the contact site covering approximately, 1/4 of the upper back.
At this point (168 hours) the reaction was subsiding and no further action was taken.
For the test subject's protection, a decision was made to patch anyone who reacted with a "2-level" or greater during induction semi-occlusively rather than occlusively during challenge.

Applicant's summary and conclusion
- Conclusions:
- Under the conditions, of the previouly described repeated insult patch test procedure, Test Article: Calcium sulfonate (Total Base Number = 30) at 10% in Squibb Mineral Oil induced irritant responses on 26/142 (18.3%) of the test panellists who completed the study, and induced reactivity patterns that, in the opinion of the Principal Investigator, are suggestive of allergic contact dermatitis on 8/142 (5.6%) of the test panellists who completed the study.
- Executive summary:
To determine the irritation and/or sensitization potential of the test article after repeated application under occlusive patch test conditions to the skin of human subjects (non-exclusive panel). One hundred sixty-six (166) subjects, 26 males and 140 females, ranging in age from 19 to 68 years were empaneled for this test. The 9 Repeated Insult (occlusive) Patch Test (9 RIPT) was conducted.
Under the conditions, of the previouly described repeated insult patch test procedure, the test article: Calcium sulfonate (Total Base Number = 30) at 10% in Squibb Mineral Oil induced irritant responses on 26/142 (18.3%) of the test panellists who completed the study, and induced reactivity patterns that, in the opinion of the Principal Investigator, are suggestive of allergic contact dermatitis on 8/142 (5.6%) of the test panelists who completed the study.
