Skin Absorption of Anions: Part Two. Skin Absorption of Halide Ions

Pharmaceutical Research, 2016
The purpose of the study was to sort skin penetration of anions with respect to their properties and to assess their mechanisms of penetration.Aqueous solutions of halides at two concentrations were prepared and quantitative penetration studies were carried out for 24 h using Franz diffusion cells. The iodide permeation was also measured after blocking

Absorption of chemicals through compromised skin

International Archives of Occupational and Environmental Health, 2009
Skin is an important route of entry for many chemicals in the work place. To assess systemic uptake of a chemical in contact with the skin, quantitative information on dermal absorption rates of chemicals is needed. Absorption rates are mainly obtained from studies performed with intact, healthy skin.

Skin absorption from patch test systems

Contact Dermatitis, 1987
The development of topical drug products requires testing for skin toxicology reactions. A variety of patch test systems are available with which chemicals are applied to skin. The purpose of this study was to determine the skin absorption of paraphenylenediamine (PPDA) from a variety of such systems.

Absorption of Lawsone Through Human Skin

Cutaneous and Ocular Toxicology, 2007
Lawsone (2-hydroxy-1,4-naphthoquinone) is the principal color ingredient in henna, a color additive approved with limitations for coloring hair by the Food and Drug Administration (FDA) under 21 CFR 73.2190. In 2002, the scientific committee on cosmetics and non-food products (SCCNFP), now known as the scientific committee for consumer products (SCCP),

Skin absorption and human risk assessment

Chemico-Biological Interactions, 2002
A common practice is to assume that percutaneous absorption does not significantly contribute to total bioavailability and therefore, absorption through other routes is more important to human risk assessment. The skin can represent a significant barrier to absorption, but some substances are absorbed to a significant extent. Since there is a potential

Absorption of hydrazine through canine skin

Toxicology and Applied Pharmacology, 1972
Abstract Hydrazine, in doses of 3–15 mmoles/kg, was applied to the chest of anesthetized male mongrel dogs. Blood samples were withdrawn at intervals and analyzed for plasma glucose and hydrazine contents, for red cell glutathione content and glutathione peroxidase activity.
