What is poloxamer 407 used for?
Poloxamer 407 has been used as a detergent, surfactant, and stabilizer. It facilitates the solubilization of hydrophobic molecules, promoting their rapid and complete dissolution in polar media [6,47].
Why is poloxamer 407 used in toothpaste?
POLOXAMER 407 Different types of polymer are widely used for toothpastes as an emulsifier or as a surfactant. Poloxamer 407 is used in Brilliant Smile’s toothpaste and mouthwash, where the substance forms a thin protective surface that makes the tooth surface smoother.
Is poloxamer 407 an active ingredient?
Poloxamer 407 (Inactive Ingredient) – Drugs.com.
How do you dissolve a poloxamer 407?
1. Dissolve 1 g of Poloxamer 407 in 10 mL distilled water to make a 10% (w/v) stock solution, or 2 g of Poloxamer 407 in 10 mL DMSO to make a 20% (w/v) stock solution. These may require heating from 40 to 50°C for about 30 minutes.
What is poloxamer 188 used for?
Poloxamer 188 is a medication used to clean wounds. Poloxamer 188 (P188) is a nonionic block linear copolymer that exhibits rheologic, anti-thrombotic, anti-inflammatory, and cytoprotective activities in various tissue injury models 5.
Is poloxamer 184 toxic?
Poloxamer 184 is one of many types of surfactants used in these products. This substance is thought to be associated with moderate toxicity of non-reproductive organs, but little research suggests that it has any effect beyond mild skin irritation.
What is the difference between poloxamer 188 and 407?
Given its low toxicity, PXM-188 is one of the most common surfactants in parenteral applications [3], [5]. PXM-407 is also an ABA block type copolymer, containing approximately 70% PEO and 30% PPO. PXM-407 exhibits reverse thermal gelation in concentrations above 20%, and has a non-toxic nature [6], [7].
Is titanium dioxide safe in tooth paste?
Is Titanium Dioxide Safe in Toothpaste? The mineral-based ingredient has been used in a number of products, specifically in the cosmetic and drugs industry and is recognized as safe by the FDA. When formulated into a toothpaste, titanium dioxide is safe to use and does not create any additional risks to human health.
Is carrageenan safe in toothpaste?

What is poloxamer made from?
Poloxamer is composed of triblock copolymers of polyethylene oxide (PEO)-polypropylene oxide (PPO)-polyethylene oxide (PEO), shown in Fig. 9.13 [115]. As a nonionic surfactant, the synthetic polymer has been previously used in drug delivery and medical imaging applications.
Is poloxamer 407 ionic or covalent?
non-ionic surfactant
Among this family of copolymers, poloxamer 407 is a non-ionic surfactant with reversible gelation properties above a particular polymer concentration and a particular temperature.
