What is Glyceryl Lactopalmitate?
Glyceryl lactopalmitate (CAS Number 1338-09-6) is a synthetic emulsifier and formulation aid created by combining glycerin with lactic acid and palmitic acid. As an emulsifier, it functions by reducing surface tension between immiscible ingredients like oil and water, allowing them to form stable, uniform mixtures. This ingredient belongs to the broader category of glycerol esters, which are widely used in food processing to improve product consistency and shelf life.
Common Uses
Glyceryl lactopalmitate is used primarily in baked goods, including breads, cakes, and pastries, where it improves dough handling properties and crumb structure. It is also employed in margarine and shortenings to enhance texture and stability. The additive may be found in certain confectionery products, dairy preparations, and other processed foods where emulsification is needed. As a formulation aid, it can also assist in creating stable emulsions and improving the overall quality of food products during manufacturing.
Safety Assessment
Glyceryl lactopalmitate has not been designated as Generally Recognized as Safe (GRAS) by the FDA, meaning it has not undergone the formal GRAS review process. However, this designation does not indicate an unsafe substance—rather, it reflects that the ingredient has not been formally submitted for or granted GRAS status in the United States. The compound is derived from common food components (glycerin, lactic acid, and palmitic acid), each of which has an established history of safe use in food.
According to FDA records, there have been zero adverse events reported and zero recalls associated with glyceryl lactopalmitate, suggesting no documented safety incidents in commercial food products. The lack of adverse event reports and recalls provides a measure of safety assurance based on real-world usage data.
The individual components of this emulsifier—glycerin, lactic acid, and palmitic acid—are well-established food ingredients with recognized safety profiles. Glycerin is widely used in foods and approved as GRAS. Lactic acid is a naturally occurring organic acid used in numerous food applications. Palmitic acid is a saturated fatty acid found naturally in many foods including palm oil, meat, and dairy products.
Regulatory Status
Glyceryl lactopalmitate is approved for use as a food additive in several countries and regions, including the European Union, where it is listed as an authorized food additive under specific conditions. In the United States, while not GRAS-designated, the ingredient may be used in food products under FDA regulations governing food additives, provided it meets purity and usage specifications. Its permitted use in other developed food safety systems indicates regulatory acceptance by authorities outside the United States.
The regulatory status differs from an outright prohibition or restriction, which would apply only to substances with demonstrated safety concerns. The absence of GRAS status in the U.S. may reflect the timing of submission or lack of a formal petition process rather than safety concerns.
Key Studies
Limited published literature specifically addresses glyceryl lactopalmitate in isolation. However, extensive research supports the safety of its constituent components. Studies on glycerol esters generally, and on lactic acid and palmitic acid individually, demonstrate safe profiles when used at typical food additive levels. The toxicological data for similar emulsifiers in the glycerol ester category indicate low systemic toxicity and minimal absorption of intact compounds through the gastrointestinal tract.
The European Food Safety Authority (EFSA) has evaluated various glycerol esters used in food, establishing acceptable daily intakes and usage guidelines. Digestive fate studies show that glycerol esters are hydrolyzed in the gastrointestinal tract into their component fatty acids and glycerol, which are normal metabolic substrates.
