An emulsion is a mixture of oil and water. AI3-03901. Sorbitan monolaurate was tested at aqueous solution of 30% and 100% in a Schwartz Prophetic Patch Test (two exposures of 72 h, seven days apart) for allergens using 30 and 50 human subjects, respectively.2626 ■■■■■ The additive is a yellow/amber oily liquid, it is insoluble in water. I’ve been doing a lot of research into the greenest cars, and so far I’ve boiled it down to the following list. Following a request from the European Commission, the Panel on Food Additives and Nutrient Sources added to Food (ANS) was asked to re‐evaluate the safety of sorbitan monostearate (E 491), sorbitan tristearate (E 492), sorbitan monolaurate (E 493), sorbitan monooleate (E 494) and sorbitan monopalmitate (E 495) when used as a food additive. When applied to sorbitan monolaurate, this would correspond (based on its molecular weight) to an ADI of 21 mg sorbitan monolaurate/kg bw per day. Polysorbate 20 (common commercial brand names include Scattics, Alkest TW 20 and Tween 20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan before the addition of lauric acid.Its stability and relative nontoxicity allows it to be used as a detergent and emulsifier in a number of domestic, scientific, and pharmacological applications. Submitted by Submitted by Kemin Europa N.V. The Joint Food and Agriculture Organization of the United Nations (FAO)/World Health Organization (WHO) Expert Committee on Food Additives also assessed the additive (WHO, 1982). At the end of the experiment, a blood sample was taken from two chickens per pen (randomly selected) for routine blood haematology1717 Group size was 12 replicates with four pigs each (representing six pens with castrated males and six pens with females per treatment). The sorbitan monolaurate supplementation up to 100‐fold the recommended dose of 85 mg/kg feed did not adversely affect the health and performance of the chickens. Commission Regulation (EU) No 231/2012 of 9 March 2012 laying down specifications for food additives listed in Annexes II and III to Regulation (EC) No 1333/2008 of the European Parliament and of the Council. showed that also these specifications were met in all samples.

Request of supplementary information to the applicant in line with Article 8(1)(2) of Regulation (EC) No 1831/2003 – Scientific assessment suspended. New Window. The PECs from the use of sorbitan monolaurate in fish farmed in sea cages was calculated assuming that 100% of the maximum dose (85 mg/kg feed) is excreted to the sediment as the parent compound. Derived from renewable resources, they are non-toxic, non-irritating, and low allergen. Since the PECswaq was around the trigger value no further assessment is required for this environmental compartment. By . Sorbitan monolaurate, also known as sorbitan laurate/SML, is synthesized by the esterification of sorbitan with lauric acid. Further testing or validation of the methods to be performed through the consortium of National Reference Laboratories as specified by Article 10 (Commission Regulation (EC) No 378/2005) is not considered necessary. Empirical Formula (Hill Notation) C 24 H 44 O 6. The typical fatty acid profile of the additive sorbitan monolaurate reflects the fatty acid composition of coconut oil and is specified to contain 40–60% lauric acid, 14–25% myristic acid, 7–15% palmitic acid, < 11% oleic acid, < 10% caprylic acid, < 10% capric acid, < 7% stearic acid, < 3% linoleic acid and < 1% caproic acid. The NOAEL was derived from a study in which Wistar rats (15 males and 15 females) were fed sorbitan monolaurate at dietary levels of 0, 2.5, 5.0 and 10% for 90 days corresponding to 0, 2,100, 4,200 and 8,000 mg sorbitan monolaurate/kg bw per day for males, and 0, 2,300, 4,500 and 8,400 mg sorbitan monolaurate/kg bw per day for females. The ANS Panel (EFSA, 2017) re‐evaluated sorbitan monolaurate as a food additive together with other sorbitan esters (i.e. Sorbitan esters can react with ethylene oxide to give the polyoxyethylene derivatives, usually referred as polysorbates or Tweens®.

Linoleic acid, C17H31COOH, is an unsaturated fatty acid found in triglycerides from sunflower oil. Cancer: … Owing the lack of data, the FEEDAP Panel cannot conclude on the safety of the additive for the environment. Data for performance parameters were analysed with a mixed model considering the fixed effects of treatment, time of sampling, parity and their three‐way interactions, plus the random effect of cow with days in milk as a covariate, with the animal as experimental unit. Supplementary Information August 2015/Annex_1. Supplementary Information August 2015/Annex_1. The diets (starter, from day 1 to day 14; grower, from day 15 to day 28; finisher, from day 29 to day 35), consisting mainly of maize, wheat and soybean meal, were isonitrogenous (starter: 22.0% crude protein (CP); grower: 20.5% CP; finisher: 19.5% CP). The additive sorbitan monolaurate consists of sorbitol (and its anhydrides) esterified with fatty acids derived from coconut oil. After 10 days of treatment, erythema and oedema were seen in all treated groups and the 60% and 100% treatments also caused skin thickening. They can be used to stabilize o/w and w/o emulsions respectively. (Hazard Characterization Document), Joint FAO/WHO Expert Committee on Food Additives. Beilstein/REAXYS Number 8172514 . Ph. Animals were sacrificed and the carcasses were frozen and lyophilised. Sorbitan monolaurate (E 493) is approved as a food additive (COMMISSION REGULATION (EU) No 1129/2011)33 Others, like cream or mayonnaise, are droplets of oil in water. (i) Suggest a type of reaction that could break down sorbitan monolaurate when it is washed into drains and rivers. EPA Safer Choice. The use of the additive for salmon would give a PECswaq below the trigger value of 0.1 μg/L, whereas the use for rainbow trout, seabass/seabream and turbot would slightly exceed the trigger value. Sorbitan is primarily used in the production of surfactants such as polysorbates; which are important emulsifying agents, with a total annual demand of more than 10000 tons in 2012. Explain why triglycerides are soluble in non-polar solvents and not in water. According to these assumptions, the ANS Panel adopted a read‐across approach and concluded that there was no need to set a separate ADI for sorbitan monolaurate and the other considered esters.

MDL number MFCD00005365 None of them raises a safety concern. The FEEDAP Panel follows the approach of the EFSA ANS Panel (2017) with its proposed group ADI of 10 mg sorbitan/kg bw per day for all sorbitan monoesters, singly or in combination. Therefore, the EURL is not able to evaluate nor recommend any method for official control to determine Sorbitan monolaurate in premixtures and feedingstuffs. Sorbitan monolaurate, also known as sorbitan laurate/SML, is synthesized by the esterification of sorbitan with lauric acid. Group size was twelve replicates with 21 birds each. ..... [1] [Total 4 marks] 3. Sorbitan monolaurate. Sorbitan monolaurate is regarded as an irritant to skin and eyes but is not considered a skin sensitiser. The main intestinal metabolite sorbitan can be absorbed, and then excreted in urine unchanged, only very limited amounts being found in the whole body. Assuming similar metabolism of sorbitan monolaurate, a limited proportion of the additive will be excreted to the environment.

The sorbitan monolaurate supplementation up to 100‐fold the recommended dose of 85 mg/kg feed did not adversely affect the health and performance of weaned piglets. We encourage environmentally friendly forest management practices and do business only with companies that promote selective logging and forest regeneration. Silver can now be extracted ecologically and more efficiently than before. In addition to being a precursor for other nonionic surfactants, SL itself is useful as a low hydrophilic-lipophilic balance (HLB = 8.6) nonionic emulsifier. Parma, Italy. The Panel considered that these results would qualitatively apply to the homologous fatty esters of sorbitan. For technological additives, stability in feedingstuffs can be demonstrated by persistence of the effect, and no demonstration of homogeneous distribution is considered necessary if the efficacy of the additive as emulsifier is demonstrated. for re‐evaluation of the authorisation of the product sorbitan monolaurate, when used as a feed additive for all animal species (category: technological additive; functional group: emulsifiers).
