Carbomer is a thickening agent and it is used to increase the stability of suspension/emulsion formulations. Isopropyl alcohol is often used in topical formulations. It may be used as a solvent or as a disinfectant (if >70% concentration). Sodium hydroxide would be used to adjust the pH of the formulation, specifically in this case... 

Screening machines are evaluated on their ability to maximize both prodnct qnality and screening efficiency. One or more of the fractions, or flows, prodnced is considered to be prodnct. This prodnct has imposed on it a quality specihcation defining the acceptable particle size distribution. Often, this specihcation consists simply of particle size limits. For example, in a scalping application, the prodnct quality specihcation may be stated as 0% + 10 U.S. allowable, i.e., a sample of material that passes through the screen should contain no material coarser than a No. 10 U.S. test sieve. Similar specihcations can also be applied to dehne acceptable resnlts of a hnes removal operation. For example, a hnes specihcation of 3% maximnm allowable -60 U.S. means that the analysis of a sample taken from the material that passed over the screen would contain no more than 3% by weight passing the No. 60 U.S. test sieve.

The sulfosuccinate monoester based on undecylenic acid monoethanolamide and its antimicrobial properties was described shortly before [12]. In comparison of shampoos containing different antidandruff agents, this sulfosuccinate s performance was favorably evaluated [13]. It was neutral with respect to lipid replacement on scalp and forehead after application of the respective shampoo. This undecylenic acid-based sulfosuccinate was also found to reduce dandruff formation in another investigation [14]. 

The death of a 10-year-old girl following dermal exposure to acrylonitrile was reported by Lorz (1950).

The concentration was not specified in this case report. 

Aminolevulinic acid (ALA HCl, Levulan Kerastick) is indicated for the treatment of nonhyperkeratotic actinic keratosis of the face and scalp. It has two components, an alcohol solution vehicle and ALA HCl as a dry solid. The two are mixed prior to application to the skin. When applied to human skin, ALA is metabolized to protoporphyrin, which accumulates and on exposure to visible light produces a photodynamic reaction that generates reactive oxygen species (ROS).The ROS produce cytotoxic effects that may explain therapeutic efficacy. Local burning and stinging of treated areas of skin due to photosensitization can occur.

Ingested arsenic is known to be stored in sulfydryl rich tissue, like hair, nails or skin. ETV-ICP-MS combined with isotope dilution has been employed to measure thallium in human scalp hair from a person poisoned by thallium compared to control subjects, whereby several longitudinal concentration gradients for the analyzed segments (length 10 mm) were obtained.28...
