PEG-35 Soy Glycerides is a chemical compound, alkyl glyceride, a mixture derived from PEG (PEG stands for Polyethylene glycol) from soy oil mono- and diglycerides. The number appearing after the abbreviation PEG refers to mol of ethylene oxide and the higher this number is, the less it can penetrate the skin.
Since the PEG (Polyethylene glycol) family is very numerous and can be found in cosmetic, industrial, pharmaceutical, medical and other products, it is necessary to make an introductory statement on the subject, which is rather complex from a safety point of view because these products not only come into contact with the skin, but, as in the case of medical products, are ingested.
PEGs (polyethylene glycol) polymerise condensed ethylene oxide and water and are referred to as polyethylene glycols, but in reality they are complex chemical components, polymers bonded together. For example, plastic is polyethylene and has a hard consistency, while polyethylene combined with glycol forms a liquid. PEGylation is produced not only as etherification, but also as transesterification, which is the transformation of an alcohol by an ester. The number appearing after the abbreviation PEG refers to mol of ethylene oxide and the higher this number is, the less it can penetrate the skin.

Safety. The term 'eth' refers to the ethoxylation process (reaction with ethylene oxide) after which residues of ethylene oxide and 1,4-dioxane, chemical compounds considered carcinogenic, may remain in the final product. It depends on the degree of purity resulting from the completed reaction.

What it is used for and where
Cosmetics
Skin conditioning agent - Miscellaneous. This ingredient has the task of modifying the condition of the skin when it is damaged or dry by reducing its flakiness and restoring its elasticity.

Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable. Emulsifiers have the property to reduce the oil/water or water/oil interfacial tension, improve emulsion stability and also directly influence the stability, sensory properties and surface tension of sunscreens by modulating their filmometric performance.

Surfactant - Solubilising agent. Solubilisation facilitates the diffusion and transport of many cosmetic ingredients, even in the form of microemulsions, on the stratum corneum, improving the effectiveness of formulations.
