What are the esters of citrus acid that are waxy

Citric acid can form a variety of esters, and some of these esters can have waxy characteristics. The waxy nature of an ester largely depends on its molecular structure and the length of its carbon chains. Here are a few examples of esters derived from citric acid that might have waxy properties: 1. **Triethyl Citrate**: This is an ester of citric acid and ethanol. It is relatively low in viscosity and can exhibit some waxy characteristics depending on the formulation and concentration. 2. **Glyceryl Citrate**: This ester, formed from citric acid and glycerol, can also show waxy properties, especially in formulations where it serves as an emulsifier or thickening agent. 3. **Acetyl Tributyl Citrate**: Known for its use as a plasticizer, this ester can have a heavier, waxy texture. 4. **Propylene Glycol Citrate**: This is formed from citric acid and propylene glycol. Depending on its concentration in a mixture, it can contribute to a waxy feel. For practical or commercial applications, the specific formulation (including other ingredients, concentrations, and the presence of other waxy materials) will greatly influence the overall texture and characteristics of these esters.
