Naturechem™ PGR Emulsifier

Naturechem PGR (Propylene Glycol Ricinoleate) is a liquid emollient. Because it forms occlusive barriers, it reduces trans epidermal water loss, and also hydrates the skin through humectancy via hydrogen bonding between water and the material’s hydroxyl groups, being able to attract and bind water from the atmosphere and lower layers of the epidermis and dermis. Naturechem PGR’s stability makes it a desirable alternative to oleates.

INCI: Propylene Glycol Ricinoleate

Form: Liquid

Properties: Non-comedogenic. Lubricious. Imparts gloss. Provides cushion. Effective wetting agent and stabilizer for highly concentrated, anhydrous pigmented products and dye dispersions.

Applications: Lipsticks, lip balms, creams & lotions, lip treatments, massage oils


Food Colorant

2-Vinylpyridine is the key intermediate in the production of the API, betahistine, an anti-vertigo medicine.

2-Vinylpyridine is a reactive monomer and once polymerized, the nitrogen is less exposed/accessible than its counterpart, 4-Vinylpyridine. It can be copolymerized with many other monomers, in particular cationic monomers, such as acrylamide, acrylates, and also with other vinyl-based monomers (e.g. styrene). The benefit of the addition of a 6-membered heterocyclic moiety is the increased Van der Waals forces which impart better electrostatic forces to the finished polymer, improving adhesion.
