Brief summary: The purpose of this study is to determine the skin irritation potential of RUT058-60 after repetitive patch application to abraded and non-abraded skin of human subjects.

Detailed description: This Cumulative Irritation Evaluation is designed to determine the skin irritation potential of RUT058-60, after repetitive patch application to abraded and non-abraded skin of healthy human subjects. Abraded skin will be challenged because the Test Product may be used, in practice, on non-intact skin. The primary research objective in this study is determine the skin irritation potential of RUT058-60. This question will be answered based on the observed results acquired evaluating its application to the abraded and non-abraded skin of at least 30 volunteer subjects, on the test product relative to the control readings.

A sufficient number of subjects will be recruited into the study to ensure 30 subjects, including both males and females, complete the study. Prior to the first application of test materials, designated skin sites will be abraded using the Tape Stripping Procedure. Occlusive patches will be used to apply approximately 0.02 mL of Test Product, Positive Control and Negative Control to abraded and non-abraded sites on the skin in the scapular region of each subject's back. The irritation potential of the test materials will be determined over the course of a 21-day challenge period on at least 30 subjects. A test material will be applied to the same site, abraded and non-abraded, on each day for 21 days. The six skin sites will be evaluated visually prior to each patch application and following the final patch removal.

Eligibility criteria: Inclusion Criteria:

* Subjects may be of either sex, at least 18 years of age and of any race
* Subjects must be free of tattoos, sunburn, dermatoses, cuts, lesions, or other disorders on the parascapular skin of the back
* Subjects must be in good general health, as evidenced by the Subject Confidential Information and Acceptance Criteria and confirmed by screening laboratory evaluations
* Subjects must read and sign an Informed Consent Form, Subject Confidential Information and Acceptance Criteria, Authorization to Use and Disclose Protected Health Information Form

Exclusion Criteria:

* Known allergies to latex (rubber), metals, ink, tape and/or adhesives, soap, hypochlorous acid, sodium lauryl sulfate, physiological Saline
* Exposure of the upper back region to antimicrobial agents, medicated soaps, medicated shampoos, medicated lotions, or strong detergents in the 7 days prior to, or during the 3-week test period; or sun-tanning, use of tanning beds, or swimming or soaking in pools or hot tubs
* Use of topical or systemic corticosteroid, antihistamine, or anti-inflammatory medications in the 7 days prior to, or during the 3-week test period
* A medical diagnosis of a physical condition, such as a current or recent severe illness, asthma, diabetes, hepatitis, an organ transplant, mitral valve prolapse, congenital heart disease, internal prostheses, or any immunocompromised condition, such as AIDS (or HIV positive)
* Pregnancy, plans to become pregnant within the pre-test period or test days of the study, or nursing a child. Women cannot be pregnant, as evidenced by a negative urine pregnancy test, or should be of non-childbearing potential; that is, surgically sterile or postmenopausal (amenorrhea for at least 12 months)
* Any active skin rashes or breaks in the skin of the parascapular region of the back
* Any sunburn or tattoos on the skin of the parascapular region of the back
* A currently active skin disease or inflammatory skin condition, including contact dermatitis
* Participation in a clinical study in the past 7 days or current participation in another clinical study
* Any medical condition or use of any medications that, in the opinion of the Principal Investigator, should preclude participation
* Clinical laboratory assessments that are determined by the Principal Investigator to indicate a clinically relevant abnormality and/or an exclusionary medical condition
* Unwillingness to fulfill the performance requirements of the study
