Summary
This study found that three types of Olaflur, a fluoride compound, are safe for oral care products. Skin and oral mucosal irritation tests showed minimal to no adverse effects at tested concentrations.
Area of Science:
- Toxicology
- Oral Health
- Dermatology
Background:
- Fluorides are essential in preventing dental caries through oral care products.
- Limited toxicological data exists for Olaflur, a novel fluoride compound in China.
- Three Olaflur variants (cetylamine, stearylamine, oleylamine) were investigated.
Purpose of the Study:
- To evaluate the safety of three Olaflur variants for oral care applications.
- To assess the skin irritation and sensitization potential of Olaflur compounds.
- To determine the oral mucosal irritation effects of Olaflur.
Main Methods:
- Utilized reconstructed human epidermis models for skin irritation testing.
- Employed the '2 out of 3' approach for skin sensitization assessment.
- Conducted oral mucosal irritation tests using animal models.
Main Results:
- No skin irritation was observed for any Olaflur type at 0.515% and 1.97% concentrations.
- All three Olaflur compounds demonstrated no sensitization potential.
- Oral mucosal irritation tests indicated minimal to no irritation at tested concentrations.
Conclusions:
- Olaflur variants are safe for use in oral care products under recommended conditions.
- The toxicological profile supports the use of these Olaflur compounds.
- Further research may explore long-term effects and broader applications.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
Local Anesthetics: Chemistry and Structure-Activity Relationship
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
