Popular questions
What is vegetable glycerin?
Vegetable glycerin is glycerol (E422) derived from plant oils (e.g., soybean, palm, coconut); it’s chemically identical to other glycerin and commonly used as a humectant and sweetener.
Is glycerin bad for you?
Generally no—at typical food and cosmetic levels it’s considered safe (FDA GRAS; EFSA found no safety concern at reported uses); large amounts may cause bloating, diarrhea, or thirst.
Is glycerin good for your skin?
Yes—glycerin is a humectant that draws and holds water in the outer skin layers, helping hydration and barrier function; very high, undiluted use can feel sticky or occasionally irritate.
What is glycerin used for?
In foods it works as a humectant, mild sweetener, thickener, and solvent/carrier for flavors and colors to keep products moist and stable; it’s also used in pharmaceuticals and personal care as a moisturizer, solvent, and plasticizer.
What is glycerin made of?
It’s most often produced by hydrolysis, saponification, or transesterification of natural triglycerides from plant or animal fats; it can also be made by microbial fermentation of sugars or synthetically from petrochemical routes.
Is ester gum bad for you?
No—at permitted food levels it’s considered safe; EFSA set an acceptable daily intake of 25 mg/kg body weight, and typical exposures from beverages are well below this.
What is ester gum in drinks?
It’s a weighting agent/emulsifier that keeps citrus flavor oils evenly dispersed in soft drinks, preventing separation and “ringing” at the surface; it’s often used as an alternative to brominated vegetable oil.
Is ester gum vegan?
It’s derived from wood rosin (from pine trees) reacted with glycerol; while the rosin is plant-based, glycerol can be plant-, animal-, or synthetic-derived, so vegan status depends on the supplier—check manufacturer or certification.
What is ester gum made of?
Glycerol esters of wood rosin—produced by reacting refined wood rosin (rosin acids from pine) with glycerol and then purifying the product.
What is ester gum used for?
Mainly to emulsify and weight citrus oils in soft drinks so they stay uniformly mixed; it’s also used in chewing gum and some desserts as a stabilizer.
