A Gel That Helps Nicotine Absorb Through Your Skin

A specialized gel formula designed to help nicotine pass through the skin or mouth lining without crystallizing or rubbing off on clothes.

What it covers

This patent describes a gel that delivers nicotine through the skin or mucosal surfaces. It uses a specific solvent system containing a mixture of water, alcohol, a monoalkyl ether of diethylene glycol, and a glycol. By keeping these ingredients in precise ratios, the gel prevents the nicotine from crystallizing on the skin surface, which helps it absorb more effectively. It also reduces the chance of the medicine rubbing off onto clothing or other people.

What it doesn't cover

• —Does not cover solid nicotine patches that use an adhesive backing to stay on the skin
• —Does not cover nicotine delivery systems that rely on inhalation or combustion
• —Does not cover formulations that lack the specific ratio of diethylene glycol ether to glycol
• —Does not cover occlusive delivery systems that seal the skin off from the air

The clever bit

The innovation lies in the specific solvent ratio that balances skin penetration with the physical stability of the gel, preventing the drug from turning into solid crystals on the skin surface.

Why it matters

Transdermal delivery is a key method for smoking cessation therapy. By improving how nicotine moves through the skin, this technology aims to make nicotine replacement therapy more consistent and less messy than traditional patches or gums. It represents an effort to refine drug delivery for better patient compliance.
