A novel, simple, validated stability indicating HPLC method was developed for determination of Koptrizon and Tinosorb S. Stability indicating power of the method was established by forced degradation study. The chromatographic separation was achieved with Waters X Bridge C18 column, by using mobile phase consisting of a mixture of acetonitrile : tetrahydrofuran : water (38 : 38 : 24, v/v/v). The method fulfilled validation criteria and was shown to be sensitive, with limits of detection (LOD) and quantitation −1 −1 (LOQ) of 0.024 and 0.08 gmL for Koptrizon and 0.048 and 0.16 gmL for Tinosorb S, respectively. The developed method is validated for parameters like precision, accuracy, linearity, solution stability, specificity, and ruggedness as per ICH norms.

  • Sun Lotion Chemicals As Endocrine Disruptors
    HORMONES 2015, 14(1):32-46 Review Sun lotion chemicals as endocrine disruptors Sotirios Maipas, Polyxeni Nicolopoulou-Stamati National and Kapodistrian University of Athens, School of Medicine, First Department of Pathology and Cytology Unit, 1st Pathology Laboratory, Athens, Greece Both authors contributed equally to this work ABSTRACT Ultraviolet solar radiation is a well-known environmental health risk factor and the use of sun lotions is encouraged to achieve protection mainly from skin cancer. Sun lotions are cosmetic commercial products that combine active and inactive ingredients and many of these are associated with health problems, including allergic reactions and endocrine disorders. This review focuses on their ability to cause endocrine and reproductive impairments, with empha- sis laid on the active ingredients (common and less common UV filters). In vitro and in vivo studies have demonstrated their ability to show oestrogenic/anti-oestrogenic and androgenic/ anti-androgenic activity. Many ingredients affect the oestrous cycle, spermatogenesis, sexual behaviour, fertility and other reproductive parameters in experimental animals. Their presence in aquatic environments may reveal a new emerging environmental hazard.

  • Sun Protection
    DRUG NEWS Recommending the Best Sun Protection Clinical Pearls: o Recommend a “broad-spectrum” sunscreen – one that covers UVB, UVA1, and UVA2. o Recommend SPF 30-50 o Advise on non-pharmacological sun protection methods o Emphasize proper sunscreen application technique o Emphasize skin protection when taking drugs known to cause photosensitivity. Familiarize yourself with known implicated drugs by referring to appendix 2. Background 1-4 The sun emits 3 types of ultraviolet (UV) radiation: UVC (100-290 nm), UVB (290-320 nm), and UVA (320 -400 nm). UVA rays can be further divided into the shorter UVA2 rays and the longer UVA1 rays. UVC rays, the shortest rays, are completely absorbed by the ozone layer, whereas UVB rays penetrate the epidermis and UVA rays, the longest rays, penetrate into the dermis. The main consequence of UVB irradiation is sunburn, but can also include immunosuppression and skin cancer. Consequences of UVA radiation include: phototoxicity (i.e. involvement in drug-induced sun sensitivity reactions), photo-aging, immunosuppression, and skin cancer. What is SPF? 2,5,6,7 It is easy to be misled by Sun Protection Factors (SPF). SPF is assessed through a standardized test by finding the ratio of the minimal dose of solar radiation that produces perceptible erythema (i.e., minimal erythema dose) on sunscreen-protected skin compared with unprotected skin. Sunburn is caused primarily by UVB rays (and shorter UVA2 rays), and thus SPF indicates mostly UVB protection. However, UVA protection is equally important since it is responsible for photo-aging and cancer. Therefore, it is important to look for the phrase “broad spectrum” when choosing a sunscreen as broad spectrum indicates both UVB and UVA protection.

Chemotechnique Diagnostic’s 34 years of continuous growth and development has been the result of our belief in building strong and long term business relationships with our global network of distributors, combined with the ongoing support and contributions of our product-user base of physicians. Our commitment is to continue serving dermatology in future years... maintaining our leadership position. During the past year we have invested in new state of the art equipment in both the analytical and production sector and developed a closed loop system in the production of haptens. When looking at our website you will note that we have made it possible also for patients to freely access our database of extensive information regarding the haptens and being able to print information sheets. We have also changed the site to be adapted to mobile platforms such as mobile phones, iPads and similar devices. There will as always be additions and amendments in our range and these are found at the end of the Patch Test Products & Reference Manual.
