What is Ammonium Persulphate Ammonium persulfate is widely used in making hair bleaches for the cosmetics industry. Product Specifications.
Ammonium persulfate is used for photography. Ammonium persulfate is used as an additive for preserving the food. Ammonium persulfate is used as an oxidising agent. Ammonium persulfate is used to wash the infected yeast.
Ammonium persulfate is used for removing the pyrogallol stains. Ammonium persulfate is used as a depolarizer in batteries. Ammonium persulfate is used as a common ingredient in the hair bleaches. Hydraulic fracturing uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground.
These cracks in the rock then allow oil and natural gas to flow, increasing resource production. A mixutre of ammonium persulfate and sodium peroxide will explode if subjected to crushing in a mortar , heating, or if a stream of carbon dioxide is passed over it. Ammonium persulfate APS and hydrogen peroxide H2O2 are used as oxidants in many industrial processes and are the main constituents of standard hair bleaching products.
In a previous study, it was demonstrated that aerosols of Ammonium persulfate induce alterations in airway responsiveness. Exposure to the aerosols altered neither baseline airway resistance, dynamic elastance, slope of inspiratory pressure generation nor arterial blood pressure and blood gas measurements.
The results demonstrate that hair bleaching products containing persulphates dissolved in H2O2 cause airway hyperresponsiveness to acetylcholine in rabbits. A cross sectional study was performed in 32 of 33 employees of a persulphate producing chemical plant. Eighteen of 23 workmen from the same plant with no exposure to persulphates were taken as controls. Also, information was collected from medical records of the seven subjects who had left the persulphate production for medical reasons since Specific immunoglobulin E IgE to the same environmental allergens as in the skin test, and total IgE were measured.
Lung function and bronchial responsiveness to histamine were assessed by standard procedures. Workplace concentrations of Ammonium persulfate were estimated by area and personal monitoring. The amount of persulphate was analyzed as sulphur by inductively coupled plasma emission spectrometry. Work related rhinitis was reported by one subject with exposure to persulphates, conjunctivitis and bronchitis were reportedly related to work by two controls.
There were no cutaneous reactions to persulphates in either group. Four non-atopic subjects exposed to persulphates, and two controls, one atopic and one non-atopic, were considered to be hyperresponsive to histamine. Six of the ex- workers left because of work related contact dermatitis.
Sodium, Potassium, and Ammonium Persulfate are inorganic salts used as oxidizing agents in hair bleaches and hair-coloring preparations. They are used in professional product bleaches and lighteners at similar concentrations. Much of the available safety test data are for Ammonium Persulfate, but these data are considered applicable to the other salts as well. Acute dermal, oral, and inhalation toxicity studies are available, but only the latter are remarkable, with gross lesions observed in the lungs, liver, stomach, and spleen.
Ammonium Persulfate as a moistened powder was not an irritant to intact rabbit skin, but was sensitizing in a saline solution to the guinea pig. It was slightly irritating to rabbit eyes.
According to the TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of ammonium persulfate is or greater; the data may be greatly underestimated. We are offering Ammonium Persulfate Cat. A as a possible alternative. Please read the alternative product documentation carefully and contact technical service if you need additional information.
Ammonium persulfate Chemical Properties,Uses,Production Outline Ammonium persulfate is white, odorless single crystal, the formula is NH4 2S2O8, it has strong oxidation and corrosion, when heated, it decomposes easily, moisture absorption is not easy, it is soluble in water, the solubility increases in warm water, it can hydrolyze into ammonium hydrogen sulfate and hydrogen peroxide in an aqueous solution. The dry product has good stability, storage is easy, and it has the advantage of convenience and safety and so on.
It is mainly used as an oxidizing agent and the preparation of hydrogen peroxide, potassium persulfate and other persulfate. It can be used as free initiator of polymerization reaction, particularly vinyl chloride emulsion polymerization of polymerizable compound and redox polymerization.
It can be used as bleaching agent in grease, soap industry. It can be used to prepare aniline dyes and dye oxidation and electroplating industry, photographic industry and chemical analysis. For food-grade, it can be used as modifier of wheat, brewer's yeast mildew. It can be used as metal etchant, circuit board cleaning and etching, copper and aluminum surface activation, modified starch, pulp and textile bleaching at low temperature and desizing, circulating water purification treatment systems, oxidative degradation of harmful gases, low formaldehyde adhesive stick bound to accelerate, disinfectants, hair dye decolorization.
Ammonium persulfate is non-flammable, but it can release of oxygen, so it has the role of combustion-supporting, storage environment must be dry and clean, and well-ventilated. People should pay attention to moisture and rain, it should not be transported in rain. Keep away from fire, heat and direct sunlight. It should keep sealed packaging, clear and intact labels. It should be stored separately with flammable or combustible materials, organic compounds, as well as rust, a small amount of metal, and other reducing substances, it should avoid be mixed to prevent the decomposition of ammonium persulfate and cause explosion.
Chemical properties of Ammonium persulfate Ammonium persulfate is colorless monoclinic crystal or white crystalline powder. It is soluble in water, the solubility is Immunological sensitization to LMW agents is often for life and levels of specific IgG may persist for many years [4].
This IgG persistence was also observed by Vanoirbeek et al. It has been suggested that IgG1 may be important for monitoring the effect of exposure to LMW agents, and particularly to isocyanates, before the onset of the condition [38] , although we did not confirm this possible role in our study.
Furthermore, it has been reported that an increase in levels of serum IgG, which matches with the decrease of the AHR and inflammatory response, may have a protective effect in this model of OA [39].
Recent studies with asthmatic patients showed a progressive increase in IgG levels with prolonged exposure to allergens [40] , [41]. To our knowledge, this is the first study to assess the persistence of systemic and ventilatory responses in an animal model of OA due to persulfate salts after the end of exposure to the causal agent.
Our experiments show that the progressive decrease in the asthmatic response over time observed in mice may mirror that in patients with OA when exposure to the causal agent ceases [14]. However, many of these patients do not completely recover from their asthmatic symptoms [17] , supporting the notion that complete removal from the workplace is not more likely to avoid symptoms than continued exposure [14].
In this context, the mouse model described in this study shows evidence that animals exhibit systemic sensitization which makes them susceptible to developing a new asthmatic response when they are re-exposed to the causal agent. This finding has implications for the recurrence of asthma symptoms. No additional contributions. Browse Subject Areas?

Abstract Introduction Since persulfate salts are an important cause of occupational asthma OA , we aimed to study the persistence of respiratory symptoms after a single exposure to ammonium persulfate AP in AP-sensitized mice. Results AP-treated mice showed a sustained increase in AHR, lasting up to 4 days after the challenge.
Introduction Occupational asthma OA is one of the most common forms of lung-related occupational diseases in Europe, and its annual incidence is increasing. Pulmonary function measurement Airway hyperresponsiveness. Bronchoalveolar lavage After blood sampling, bronchoalveolar lavage BAL was performed. Lung pathology After BAL, lungs were instilled with formaldehyde 3.
Results Airway hyperresponsiveness to methacholine To assess the course of airway hyperresponsiveness AHR to methacholine, AUC was calculated for each individual mouse in each experimental group. Download: PPT. Figure 1.
Airway hyperresponsiveness AHR to methacholine expressed as resistance R was measured 1 hour, 4 hours, 8 hours, 24 hours, 4 days, 8 days and 15 days after intranasal instillation by the forced oscillation technique to increasing concentrations of methacholine. Pulmonary inflammation bronchoalveolar lavage No differences were found in the total cell count in any of groups assessed at any time point.
Figure 2. Figure 3. Figure 4. Blood was collected 1, 4, 8 and 24 hours, and 4, 8 and 15 days after AP challenge. Discussion The present study shows that, in dermally sensitized mice, after exposure to persulfate salts the asthmatic response peaks early after the challenge, and then decreases gradually over time.
