I googled 'ester and plasticizer" and I'm as clueless as I was before. I have at least 4 bottles that are exact duplicates of this bottle. Same bottle, same contents, same age and made at the same time because I had only 10 ml bottles, at the time. It really blew my mind when I found this particular bottle because it made me afraid that all the other juices I have made were dissolving their bottles without such visible evidence.
In a Nutshell, Plasticizers make things Softer. In things like Plastics, if they weren't used, the Many Plastics would be Too Brittle to use.
PVC Pipe when New is relatively Ductile. But over time becomes Brittle. This is because the Plasticizers that were Added have Evaporated. But if there is Too Much Plasticizer that the Plastic can Degrade into Mush.
Some Esters are Very Efficient Plasticizers. And Ester can form on their own. All my Hard Plastic Mouth Pieces in my Filler Type Cartos turned gum and some of my Bottle got Weak when I used Cinnamon Oil Based e-Liquid.
I stopped Using Cinnamon Flavors after seeing what it did to Some Plastic.

For plastics
Plasticizers for plastics are additives, most commonly phthalate ester. Almost 90% of the market for plasticizer is for PVC, giving this material improved flexibility and durability.[1] Plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing the "free volume"), and thus significantly lowering the glass transition temperature for the plastic and making it softer. For plastics such as PVC, the more plasticizer added, the lower its cold flex temperature will be. This means that it will be more flexible and its durability will increase as a result of it. Plasticizers evaporate and tend to concentrate in an enclosed space; the "new car smell" is caused mostly by plasticizers evaporating from the car interior.
Plasticizers make it possible to achieve improved compound processing characteristics, while also providing flexibility in the end-use product. Ester plasticizers are selected based upon cost-performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processibility, permanence and other performance properties. The wide variety of ester chemistries that are in production include sebacates, adipates, gluterates, phthalates, azelates, and other specialty blends. This broad product line provides an array of performance benefits required for the many elastomer applications such as tubing and hose products, seals and gaskets, belts, wire and cable and print rolls. Low to high polarity esters provide utility in a wide range of elastomers including nitrile, polychloroprene, EPDM, chlorinated polyethylene, and epichlorohydrin. Plasticizer-elastomer interaction is governed by many factors such as solubility parameter, molecular weight and chemical structure. Compatibility and performance attributes are key factors in developing a rubber formulation for a particular application.[2]
Plasticizers also function as softeners, extenders, and lubricants, and play a significant role in rubber manufacturing.
Ester plasticizers
Plasticizers used in PVC and other plastics are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. These compounds are selected on the basis of many critieria including low toxicity, compatibility with the host material, nonvolatility, and expense. Phthalate esters of C8 alcohols meet these specifications and common plasticizers.
