Kosher Vegetable Glycerin ●
TL;DR. This ingredient is primarily a humectant, helping bind water in the outer skin layers and reduce formula dry-down. It also functions as a water-soluble solvent, texture modifier, and support ingredient in creams, cleansers, serums, and oral care.
What does Kosher Vegetable Glycerin do in a cosmetic formula?
This ingredient is primarily a humectant, helping bind water in the outer skin layers and reduce formula dry-down. It also functions as a water-soluble solvent, texture modifier, and support ingredient in creams, cleansers, serums, and oral care.
Is Kosher Vegetable Glycerin clean?
From a clean-beauty perspective, this ingredient is widely accepted, well-tolerated, and not a common restricted-list concern. Sensory drawbacks are usually tackiness at higher levels rather than irritation.
Is Kosher Vegetable Glycerin sustainable?
This material is commonly made from it oil processing, with palm, coconut, soy, or rapeseed as possible feedstocks. It is readily biodegradable, and the main sustainability question is feedstock traceability, especially when palm-derived.
Is Kosher Vegetable Glycerin COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when sourced and processed according to the standard’s rules. It fits Green Chemistry well because it can come from renewable feedstocks, is readily biodegradable, and is typically produced through relatively simple fat-splitting or saponification routes.
How does Kosher Vegetable Glycerin work chemically?
The molecule is a small three-carbon triol with three hydroxyl groups, which explains its strong water binding, full water miscibility, and high hygroscopicity. Typical use levels are about 1 to 10% in leave-on skin care, with higher levels possible in hand and body products, and it is broadly stable across normal cosmetic pH ranges.
