The Active Ingredients of Campho-Phenique
Campho-Phenique is a well-known over-the-counter (OTC) medication used for its pain-relieving and antiseptic properties. The efficacy of the product stems from its two key active ingredients: camphor and phenol. For both the liquid and gel versions of the standard Campho-Phenique formulations, the concentration of active ingredients is consistently maintained to deliver reliable results.
The ingredient list, as found on the product's packaging and confirmed by the FDA's DailyMed database, specifies the concentrations:
- Camphor: 10.8%
- Phenol: 4.7%
This combination, known as 'Camphorated Phenol,' works synergistically. The camphor provides an initial cooling, numbing sensation, while the phenol contributes its anesthetic and germ-killing properties. It's crucial to note that the total amount of camphor is intentionally kept below the FDA's 11% limit for safety.
Formulations: Liquid vs. Gel
Campho-Phenique is available in two primary forms: a liquid and a gel. A common question from consumers is whether the concentration of active ingredients differs between these two formulations. The answer is no; both the liquid and gel products contain the same 10.8% camphor and 4.7% phenol. The primary difference lies in the inactive ingredients, which determine the product's consistency and absorption rate.

The Pharmacological Role of Camphor
Camphor is a volatile, crystalline substance derived from the wood of the camphor tree. In topical medications like Campho-Phenique, it serves a dual purpose. First, it acts as a topical analgesic, creating a cooling sensation that distracts from and temporarily relieves pain and itching. Second, camphor possesses mild antiseptic properties, which contribute to preventing infection in minor skin injuries. The concentration of 10.8% is carefully chosen to provide these benefits without exceeding the FDA-mandated safety threshold.
Safety and FDA Regulations
The FDA's decision to cap the concentration of camphor at 11% was a direct response to a history of camphor poisoning cases, particularly in children. Camphor can be toxic if ingested, even in small amounts, and can cause serious adverse effects. The regulations ensure that OTC products contain a safe, effective concentration for external use, while highlighting the importance of proper storage and usage.
Key safety precautions when using Campho-Phenique include:
- For external use only: The product should never be ingested. Ingestion requires immediate medical attention.
- Avoid broken or large areas of skin: Applying camphor to broken or damaged skin can lead to increased absorption and potential toxicity.
- Keep away from children: All camphor-containing products should be stored out of the reach of children to prevent accidental ingestion.
- Do not heat: Heating camphor-containing products can create flammable vapors and cause burns.

Conclusion
In summary, Campho-Phenique consistently contains 10.8% camphor in its active ingredient complex, camphorated phenol. This concentration, alongside 4.7% phenol, is formulated to provide effective pain relief and antiseptic action for various minor skin ailments. The key takeaway is that whether you choose the liquid or gel version, the amount of camphor is identical and adheres to strict FDA safety guidelines. Following all usage and storage warnings is crucial to ensure the medication is used safely and effectively.
