Safety and efficacy of a feed additive consisting of glyceryl polyethyleneglycol ricinoleate (PEG castor oil) for all animal species (FEFANA asbl).
Abstract: Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of glyceryl polyethyleneglycol ricinoleate (PEG castor oil) as technological feed additive for all animal species. PEG castor oil is safe at a maximum concentration in complete feed of 90 mg/kg for chickens for fattening and other minor growing poultry; 134 mg/kg for laying hens and other laying/breeding birds kept for egg production/reproduction; 121 mg/kg for turkeys for fattening; 162 mg/kg for piglets and other minor growing ; 194 mg/kg for pigs for fattening; 236 mg/kg for sows other minor reproductive ; 231 mg/kg for dairy cows and other dairy ruminants (other than sheep/goats); 142 mg/kg in rabbits and 377 mg/kg in veal calves; 356 mg/kg for cattle for fattening and other growing ruminants, sheep, goat, horses and cats; 427 mg/kg for dogs; 407 mg/kg for salmonids and other fin fish; and 1,584 mg/kg for ornamental fish. For other growing species and non-food producing animals, the additive is considered safe at 90 mg/kg complete feed. The use of PEG castor oil as feed additive for all animal species would be of no concern for the consumer. The FEEDAP Panel considered inhalation exposure of the user to the additive unlikely. PEG castor oil is not considered a skin sensitiser. The panel was not in the position to conclude on the potential of the additive to be a skin or eye irritant. The additive is a readily biodegradable substance and is not expected to pose a risk for the environment. The lack of sufficient data does not allow the FEEDAP Panel to conclude on the efficacy of PEG castor oil as an emulsifier in feedingstuffs.

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
The research article discusses the safety and efficacy of a feed additive known as glyceryl polyethyleneglycol ricinoleate or PEG castor oil for animals of various species, as assessed by the European Food Safety Authority (EFSA). The study reports that the additive is safe at specific concentrations in complete feed for different animal species and is unlikely to create risks for consumers or the environment. However, sufficient data to assess its efficacy as an emulsifier in feedingstuffs is lacking.
About the Research
- This research was prompted by a request from the European Commission to the EFSA to provide a scientific opinion on the safety and use rights of glyceryl polyethyleneglycol ricinoleate, also known as PEG castor oil, as a technological feed additive for all animal species.
- The decision was based on maximum concentrations in complete feed for various animals such as chickens, laying hens, turkeys, piglets, pigs, sows, dairy cows, rabbits, veal calves, cats, dogs, fish, and non-food producing animals.
Safety of PEG Castor Oil
- The study concluded that PEG castor oil is safe for all animals when used at the recommended concentrations in their feed. The concentrations vary by species, with the highest permitted level being 1,584 mg/kg for ornamental fish.
- For non-food producing and growing animals, the additive is safe at a concentration of 90 mg/kg in the total feed.
- The use of PEG castor oil as a feed additive is deemed to pose no risk for consumers.
- The researchers further noted that while inhalation exposure to the additive by the user is considered unlikely, they could not definitively conclude on the potential of the additive to cause skin or eye irritation due to lack of data.
Environmental Impact and Efficacy of PEG Castor Oil
- PEG castor oil was found to be a readily biodegradable substance and thus is not expected to pose a risk to the environment.
- However, the plan was not able to conclude on the effectiveness of PEG castor oil as an emulsifier in animal feed due to insufficient data.
Conclusion
- The research provides important insights into the safety and potential impact of using PEG castor oil as a feed additive for various animals. However, further studies are required to definitively establish its efficacy as an emulsifier and assess its potential to irritate the skin or eyes.
