• Recent EU Clinical Trials: A randomized, double-blind, monocentric phase IV clinical study on the ocular tolerability of a topical ophthalmic product containing Retinolpalmitat 1000 I.U. in comparison to a reference product containing Carbomer 0.2 % with repeated ocular applications over 12 months in 120 patients with keratoconjunctivitis sicca
• Inhalation Risk: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C , on spraying or dispersing much faster.
• Effects of Short Term Exposure: The substance is corrosive to the eyes and skin. Corrosive on ingestion. The vapour is severely irritating to the eyes and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the upper respiratory tract and lungs. This may result in reduced lung function and hyperreactivity of the airways.
• Description: Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC. At temperatures above 200 to 250oC, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperatures. Concentrated solutions of PAA in water is thixotropic in nature.Polyacrylic acid (PAA) is a hydrophilic colloidal solution, similar in properties to water-soluble natural gums. It is a clear, colorless, viscous stable solution. Applications include the modification of aqueous formulations for such end uses as cleaners, binders, adhesives, and emulsion paints. The sodium, potassium, and ammonium salts are effective thickeners and dispersants useful in both natural and synthetic latex systems. PAA in ceramic applications improves dry strength, dispersant action, and improved workability of the clays. PAA is stable to hydrolysis and is not susceptible to bacterial degradation. For a description of unrelated compounds expanded by twocarbon units,Poly acrylic acid (PAA or Carbomer) is generic name for synthetic high molecular weight polymers of acrylic acid. They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative charge. This makes PAAs polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume. Dry PAAs are found in the market as white and fluffy powders. Carbomer codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer. For many applications PAAs are used in form of alkali metal or amonium salts e.g. sodium polyacrylate.
• Uses: carboxypolymethylene is a binder, film-former and emulsion stabilizer. It can also help increase product viscosity. Applications of PAA may include: · to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogel · synthesizing poly(N-isopropylacrylamide)-block-PAA copolymer which responds to both temperature and pH stimuli · in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs · as thickening agent for adhesives Polyacrylic acid is used in disposable diapers and in ion exchange resins. It is also used to study solute diffusion in polyvinyl alcohol/polyacrylic acid copolymer hydrogel. It is also employed as a thickening, suspending, emulsifying and dispersing agent in pharmaceuticals, cosmetics, adhesives and paints. Further, it is used for the preparation of poly(N-isopropylacrylamide)-block-polyacrylic acid copolymer which responds to both temperature and pH stimuli. In addition to this, it is used in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs.
