Chlorine releasing solutions, such as liquid bleach and solutions of bleaching powder, can burn the skin and cause eye damage, [2] especially when used in concentrated forms. As recognized by the NFPA, however, only solutions containing more than 40% sodium hypochlorite by weight are considered hazardous oxidizers.
Skin whitening, also known as skin lightening and skin bleaching, is the practice of using chemical substances in an attempt to lighten the skin or provide an even skin color by reducing the melanin concentration in the skin. Several chemicals have been shown to be effective in skin whitening, while some have proven to be toxic or have ...
The side effects are similar to those of other tetracyclines. Skin reactions with sunlight have been reported. [15] Like only few other known tetracycline derivatives, demeclocycline causes nephrogenic diabetes insipidus. [16] Furthermore, demeclocycline might have psychotropic side effects similar to lithium. [17]
Prolonged skin contact can result in DCM dissolving some of the fatty tissues in skin, resulting in skin irritation or chemical burns. [32] It may be carcinogenic, as it has been linked to cancer of the lungs, liver, and pancreas in laboratory animals. [33] Other animal studies showed breast cancer and salivary gland cancer. Research is not yet ...
The grade of chlorine-based bleaches is often expressed as percent active chlorine. One gram of 100% active chlorine bleach has the same bleaching power as one gram of elemental chlorine. The most common chlorine-based bleaches are: Sodium hypochlorite (NaClO), usually as a 3–6% solution in water, usually called "liquid bleach" or just "bleach".
(Reuters) -High levels of cancer-causing chemical benzene were detected in some acne treatments from brands including Estee Lauder's Clinique, Target's Up & Up and Reckitt Benckiser-owned ...
It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. [4] It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −). The anhydrous compound is unstable and may decompose explosively.
From the above equations it can be seen that 2 moles of thiosulfate is equivalent to 70.9 grams (2.50 ounces) of active chlorine. Again the percentage of available chlorine can be calculated through the concept of normality. The gram equivalent of bleaching powder is equal to the gram equivalent of the standard titrant used.
