About:

Functions :
1. Flavor / Flavoring / Flavor Enhancer – Provides or enhances a particular taste or smell
2. Fragrance / Fragrance Component – Provides or enhances a particular smell or odor
3. Humectant – Binds with water to increase skin hydration. Also enhances water absorption of the skin
4. Viscosity Controlling Agent – Maintains or alters the thickness of a liquid, mostly used in cosmetics

1,3-Butanediol (also known as 1,3-butylene glycol, butane-1,3-diol, or 1,3-dihydroxybutane) is an organic chemical, a diol. It is commonly used as a solvent for food flavoring agents and in the manufacturing of resins.

Butylene glycol is used as solvents and viscosity decreasing agents in cosmetics and personal care products. It is used in the formulation of hair and bath products, eye and facial makeup, fragrances, personal cleanliness products, and shaving and skin care products. [1]

This is an Unapproved E-number (E1502).

Recent Findings :
Butylene glycol is used to improve the survival rates of neonatal pigs by up to 90% in a study involving ~2500 pigs. [2]
Butylene glycol has shown antibacterial and antifungal properties although its effectiveness is weaker when compared to hexylene glycol. A solution of 30% butylene glycol is as effective as a solution of 10% hexylene glycol. Both solutions killed an array of Staphylococcus and E. coli within 20 h. [3]
In long term studies where butylene glycol was fed to rats and dogs at 1.0, 3.0, and 10% levels for 2 years, no adverse effects were detected. [4]
Butylene glycol generally has limited water solubility although its fatty acid ester and nitric ester derivatives may have increased toxicity. [5]

Overall, butylene glycol has been proven to be safe in a wide range of animals from rats to pigs to dogs. Even in long term studies, no toxicity was detected. However, care must be taken when using butylene glycol as an antibacterial since its relatively weak effectiveness may contribute to antibacterial resistance.
