Popular questions
Why is triacetin bad for you?
It isn’t generally considered bad for you—regulators (e.g., EU as E1518; JECFA/EFSA) regard it as safe at permitted food-use levels and it’s metabolized to glycerol and acetate. Large exposures can cause mild gastrointestinal upset if ingested or irritation on skin/eyes from the neat liquid.
What is triacetin made from?
Triacetin is the triester of glycerol and acetic acid, typically produced by acetylating glycerol with acetic acid or acetic anhydride.
What is triacetin used for?
In foods it serves as a carrier/solvent for flavors, humectant, and emulsifier (and plasticizer in gum base); it’s also used in pharmaceuticals and cosmetics as a solvent and plasticizer for capsules and topical formulations.
How to make triacetin?
Industrially it’s made by esterifying glycerol with acetic acid or acetic anhydride in the presence of an acid catalyst, then removing water and purifying (e.g., by distillation) to obtain glycerol triacetate.
How triacetin acts as penetration enhancer?
As a lipophilic solvent/plasticizer, triacetin partitions into stratum corneum lipids, increases their fluidity, and improves drug partitioning and diffusion; it can also raise the solubility of actives at the skin surface.
What is castor oil good for?
In foods, castor oil (E1503) serves as a carrier/carrier solvent and emulsifier to help dissolve and evenly distribute colors and flavors. Outside food use, refined castor oil is also used in cosmetics as an emollient, but that’s separate from its role as a food additive.
Is castor oil good for skin?
Cosmetic-grade castor oil can act as an occlusive moisturizer and skin softener, but evidence for special skin benefits is limited and some people may experience irritation or breakouts. Use cosmetic-grade only, patch test first, and note that food-additive E1503 isn’t intended for topical use.
Is castor oil good for hair?
It can help condition hair and scalp by providing occlusive moisture, but there’s no solid evidence it promotes hair growth or thickness. Use sparingly (often diluted) to avoid heaviness or buildup.
What is castor oil used for?
As a food additive (E1503), it’s authorized in the EU as a carrier/carrier solvent and emulsifier in color and flavor preparations to ensure even dispersion. Other uses in cosmetics and industry exist but are outside food-additive regulation.
How to use castor oil on face?
If using it cosmetically, apply a small amount of cosmetic-grade castor oil diluted with a lighter oil to damp skin and patch test first, avoiding the eye area. Stop use if irritation or breakouts occur; this is separate from its intended food-additive use.
