in 2022, data indicated that polyacrylamide has 552 reported uses, compared to 110 uses reported in 2002. however, the maximum reported concen-tration of use for this ingredient has remained constant; in 2001, the maximum reported concentration of use was 2.8%, and in 2020, it was 3%. additionally, there was 1 reported use in baby lotions
maximizing the benefits of polyacrylamide (pam): usage,pam is the abbreviation of polyacrylamide, polyacrylamide is a water-soluble polymer, widely used in petroleum, paper making, metallurgy, textile, chemical industry and environmental protection. there are three major categories: anionic, cationic and non-ionic. different applications require different grades of polyacrylamide. view more
safety assessment of acrylamide/acrylate copolymers as used
a 28-d dermal toxicity assay was performed in wistar han rats (5/sex/group).16 the test substance (38% amp-acrylates/c1-18 alkyl acrylate/c1-8 alkyl acrylamide/hydroxyethylacrylate copolymer in water; 2 ml/kg) was applied to the skin at doses of 0, 100, 300, and 1000 mg/kg bw/d, under semi-occlusive conditions, for 6 h/d.
safety assessment of polyacrylamide as used in cosmetics,groups give polyacrylamide a highly hydrophilic character in this state. when polymer- ization takes place at ph 2.5 or below, the resulting polyacrylamide is not water soluble. in its cross-linked form, polyacrylamide is defined as “water-swollen” rather than water soluble.‘4p6’

degradation of polyacrylamide and its significance in nature
acrylamide at a dose of 20 mg/kg/day stimulated the degeneration of peripheral nerves and the spinal cord of rats, although no obvious effects were found at doses less than 0.2 mg/kg/day. 152

- What is polyacrylamide (PAM) used for?
- High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
- What is Pam used for in industrial water treatment?
- In industrial water treatment, PAM can be used for scale inhibition and corrosion inhibition, helping to maintain the proper functioning of equipment. It can also be employed in the maintenance of cooling water systems, reducing corrosion and microbial growth while enhancing system efficiency.
- Why is polyacrylamide used in water treatment?
- With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
- How efficient is a Pam wastewater treatment plant?
- Using this technique, a PAM wastewater treatment plant with a processing capacity of 600 m 3 ·d −1 was implemented and has been stably operated for nearly 18 months. Compared to the pervious process, the HRT decreased 50% and the COD, NH 4 -N and T-N removal efficiency increased to 93%, 92% and 67–80%, respectively.
