How Important is Allantoin?
Found at: http://www.skin-care.cl/allantoin.htm
Allantoin promotes wound healing, speeds up cell regeneration, and has a keratolytic (skin-softening) effect.

Allantoin has been termed a cell proliferant, an epithelization stimulant, and a chemical debrider in texts such as the "United States Dispensatory", "Merck Index", and "British Pharmaceutical Codex".

It is said to clean away necrotic tissue, hastening the growth of new healthy tissue.

Since Allantoin stimulates new and healthy tissue growth, healing epithelization may take place. The FDA OTC Panel has not recognized Allantoin as a wound healing agent, only as a skin protectant.

Allantoin has been also termed a counter irritant that helps alleviate the untoward skin-irritation effects of certain cosmetic ingredients such as soap and detergent surfactants, oils, and acidic or alkaline materials.

Allantoin produces its desirable effects by promoting and speeding up the healthy, natural processes of the body. It helps the skin to help itself.

Natural sources of Allantoin: The Comfrey plant and the secretions of the Chilean Snail Helix Aspersa M?ller.

TOXICOLOGICAL DATA

The U.S. Food and Drug Administration (FDA) has classified Allantoin as a Category I (safe and effective) active ingredient skin protectant.

The FDA's Tentative Final Monograph on skin protectant drug products for Over-The-Counter (OTC) human use was published in the Federal Register (Volume 48, No. 32, pp. 6820-33 and Volume 55, No. 11, pp. 25240-81). Based on the wide use and clinical acceptance of Allantoin, as well as published reports in the literature, the FDA has approved the following statements for non-prescription, drug products containing Allantoin at 0.5% to 2.0%.

   1. For the temporary protection of minor cuts, scrapes, burns and sunburn.
   2. Helps prevent and temporarily protects chafed, chapped, cracked, or wind-burned skin and lips.
   3. Relieves dryness and softens cold sores and fever blisters.
   4. Helps treat and prevent diaper rash. Protects chafed skin/minor skin irritation due to/associated with diaper rash and helps protect from/seal out wetness.

Allantoin is considered to be nontoxic, nonirritating and non-allergenic by the Schwartz patch test on 200 individuals, as published in the Federal Register (Volume 43, No. 151, pp. 34632-34). Clinical and marketing experience has confirmed that Allantoin is safe and effective in the dosage range recommended (0.5 to 2.0%) as a skin protectant.

IMPORTANT NOTE
The U.S. Food and Drug Administration acknowledges that Allantoin at 0.5 to 2.0% concentration can be used for the prevention and treatment of chafed, chapped, cracked, sunburned or wind burned skin or lips, cold sores, fever blisters and diaper rash, but considers such explicit claims as drug claims.

When Allantoin is added to a personal care product and no claims are made the product remains a cosmetic.

The natural secretions of the snail Helix Aspersa M?ller contains Allantoin combined  with natural antibiotics, glycolic acid, collagen, elastin, and other proteins and vitamins in a natural bio-compatible form.
