Hydrogenated palm stearin

Hydrogenated palm stearin (CAS 100298-99-5), also supplied under the designation glycerides, mixed hydrogenated palm kernel-oil stearin and hydrogenated palm-oil, is a fully or partially hydrogenated solid fat derived from the stearin fraction of palm oil.

Where is Hydrogenated palm stearin used?

• Food: solid fat structure in shortenings, margarines and bakery fats
• Personal care: body and consistency in stick products, balms and creams
• Coatings and adhesives: rheology modifier controlling viscosity, set speed and film hardness
• Confectionery and industrial processing: release agent and processing aid
• It functions as a structuring agent and emulsifier.
• Used to manufacture food emulsifiers.
• In chocolate and confectionery coatings it supports tempering, surface gloss and snap.
• In skin care, acts as an emollient, providing a soft and moisturising effect.

Formulation notes

• Incompatible with strong oxidising agents.
• Fully hydrogenated palm oil contains fewer artificial trans fats than partially hydrogenated palm oil.
