Common Name(s): Hydrogenated pistachio seed oil,hydrogenated pistacia vera oil

DESCRIPTION

What It Does: Provides stable emolliency from pistachio nut oil.

Why It's Used: Pistachio seed oil (pistacia vera) is naturally rich in oleic acid (c18:1, ~55%) and linoleic acid (c18:2, ~30%); hydrogenation improves oxidative stability and creates a solid/semi-solid emollient form.

How It Works: Hydrogenation of pistachio oil's oleic/linoleic acids produces primarily stearic/palmitic glycerides; improved oxidative stability; solid to semi-solid at room temperature; pistachio's rich tocopherol profile is partially retained.

Typically Found In: Solid emollient formulas,luxury nut oil skin care,stable natural formulas
