Functions of PEG-40 stearate:
PEG 40 Stearate is used in cosmetics and beauty products primarily as a surfactant and cleansing agent, because PEG Stearates' ability to clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away.
However, PEG-40 stearate is also seen as an emollient, because of secondary properties.
Unlike typical PEGs, (whose identifying number corresponds to their molecular weight) the numerical value of each PEG Stearate corresponds to the average number of ethylene oxide monomers in the polyethylene chain (from 2 - 150).
Despite the many fears regarding PEGs, they are seen as an ingredient in a large number of products because of their diverse properties.
In a study published in the Toxicology journal in 2005, entitled "Safety assessment on polyethylene glycols (PEGs) and their derivatives as used in cosmetic products," it was concluded that: "Taking into consideration all available information from related compounds, as well as the mode and mechanism of action, no safety concern with regard to these endpoints could be identified.
Based on the available data it is therefore concluded that PEGs of a wide molecular weight range (200 to over 10,000), their ethers (laureths. ceteths, ceteareths, steareths, and oleths), and fatty acid esters (laurates, dilaurates, stearates, distearates) are safe for use in cosmetics."
PEG 40 Stearate is not considered to be an irritant or sensitizer (it gave only minimal irritation in studies up to 100%), and are CIR and FDA approved for use, but not on broken skin.
Phospholipid coated microbubbles are currently in widespread clinical use as ultrasound contrast agents and under investigation for therapeutic applications.
Previous studies have demonstrated the importance of the coating nanostructure in determining microbubble stability and its dependence upon both composition and processing method.
While the influence of different phospholipids has been widely investigated, the role of other constituents such as emulsifiers has received comparatively little attention.
Herein, we present an examination of the impact of polyethylene glycol (PEG) derivatives upon microbubble structure and properties.
We present data using both pegylated phospholipids and a fluorescent PEG-40-stearate analogue synthesized in-house to directly observe its distribution in the microbubble coating.
We examined microbubbles of clinically relevant sizes, investigating both their surface properties and population size distribution and stability.
Domain formation was observed only on the surface of larger microbubbles, which were found to contain a higher concentration of PEG-40-stearate.
Lipid analogue dyes were also found to influence domain formation compared with PEG-40-stearate alone.
“Squeezing out” of PEG-40-stearate was not observed from any of the microbubble sizes investigated.
At ambient temperature, microbubbles formulated with DSPE-PEG(2000) were found to be more stable than those containing PEG-40-stearate.
At 37 °C, however, the stability in serum was found to be the same for both formulations, and no difference in acoustic backscatter was detected.
This could potentially reduce the cost of PEGylated microbubbles and facilitate simpler attachment of targeting or therapeutic species.
However, whether PEG-40-stearate sufficiently shields microbubbles to inhibit physiological clearance mechanisms still requires investigation.

Polyethylene glycol (PEG) and its derivatives are widely used in delivery systems to protect bioactive peptides and proteins against premature degradation.
In this study, we sought to understand whether or not bioactive proteins at the interface of emulsions can be protected by PEG chains during in vitro gastrointestinal digestion.
We designed an emulsion stabilised by both PEG 40 stearate (PEG 40 St) and a bioactive protein, bovine lactoferrin (LF), and we monitored the fate of LF during in vitro digestion.
The PEG–LF emulsions displayed a droplet diameter of 200 nm and remained colloidally and morphologically stable for at least 2 h in the simulated gastric fluid; in contrast, the control emulsions with LF alone showed droplet flocculation.
After 2 h of gastric digestion, the LF in these emulsions was largely protected (84% remaining), whereas only 23% LF remained in the control emulsions.
This protective effect on LF might be related to an inhibition of pepsin activity by PEG 40 St, independent of the location of the LF.
Under intestinal conditions, the PEG–LF emulsions had good stability and slower lipolysis than the control emulsions, but LF was prone to immediate degradation within 5 min, regardless of the protection from PEG 40 St, suggesting that PEG 40 St had no inhibitory effect on pancreatic proteases.
Overall, this work shows promise for using PEG 40 St, a food-grade emulsifier, to prevent premature gastric digestion of bioactive proteins following oral delivery.
Safety Information of PEG-40 stearate:
The Food and Drug Administration (FDA) reviewed the safety of PEG-8 Stearate and approved its use as an indirect food additive.
PEG-40 stearate is approved for use as defoaming agent for the coating of paper and paperboard used to package food.
The safety of the PEG Stearates has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel.
The CIR Expert Panel evaluated the scientific data and concluded that PEG-2, -6, -8, -12, -20, -32, -40, -50, -100 and -150 Stearates are safe for use in cosmetics and personal care products.
In 2002, as part of the scheduled re-evaluation of ingredients, the CIR Expert Panel considered available new data on the PEG Stearates and reaffirmed the above conclusion.
More safety Information of PEG-40 stearate:
CIR Safety Review: The PEG Stearates, whose average number of ethylene oxide monomers range from 2 to 150, were nonlethal at levels up to 10 g/kg.
They gave evidence of only minimal skin irritation and minimal eye irritation when tested at 100%. PEG-8, -40 and -100 Stearates produced no significant changes in growth, histopathologic observations or hematologic values in long-term feeding studies.
Multiple generation studies of PEG-8 and -40 Stearates were negative for effects on reproduction.
Clinical studies on the PEG Stearates indicated that these ingredients were neither irritants nor sensitizers at concentrations of 25% or greater.
There was no evidence of phototoxicity or photosensitization of PEG-2 or -8 Stearates.
Because the smaller PEG Stearates were not photosensitizing the CIR Expert Panel did not expect the larger ingredients to be photosensitizing.
The CIR Expert Panel concluded that safety data on individual PEG Stearates were sufficient for a decision regarding the safety of the entire group.
FDA Code of Federal Regulations for Polyethylene glycol (400) monostearate (PEG-8 Stearate)
If the stearic acid used to make PEG-2, -6, -8, -12, -20, -32, -40, -50, -100, and -150 Stearates is from plants, these ingredients may be used in in cosmetics and personal care products marketed in the Europe according to the general provisions of the Cosmetics Regulation of the European Union.
Ingredients of animal origin must comply with European Union animal by-products regulations.
More Scientific Information about PEG-40 stearate:
PEG Stearates are the polyethylene glycol esters of stearic acid.
In cosmetics and personal care products, they are used as surfactants – cleansing agents and emollients.
Safety Measures/Side Effects of PEG-40 stearate:
However. The Cosmetics Database found PEG 40 Stearate to be a moderate to high hazard ingredient depending on usage.
The EWG issues warnings regarding: cancer, developmental and reproductive toxicity, contamination concerns, irritation, and organ system toxicity.
According to a study published in the International Journal of Toxicology, PEGs (including PEG 40 Stearate) can contain harmful impurities, including: Ethylene Oxide, known to increase the incidences of uterine and breast cancers and of leukemia and brain cancer, according to experimental results reported by the National Toxicology Program; 1,4-dioxane, a known carcinogen; PAHs, known to increase the risk of breast cancer; lead; iron; and arsenic.
Products and formulas containing PEG 40 Stearate should not be used on broken or irritated skin.
Although PEGs are considered safe for use topically on healthy skin, studies showed that patients suffering from severe burns were treated with PEG-based antimicrobial cream; this treatment resulted in kidney toxicity.
"The PEG content of the antimicrobial cream was determined to be the causative agent.
However, no evidence of systemic toxicity occurred in studies with intact skin.
Because of the observation of kidney effects in burn patients, the CIR Expert Panel qualified their conclusion on the safety of the PEG ingredients to state that cosmetic formulations containing these ingredients should not be used on damaged skin".
