Common Name(s): Montan/stearic glycerides,glycerol montan wax fatty acids (c26-c34) and stearic acid (mixed glyceride blend) ester
DESCRIPTION
What It Does: Softens and conditions skin with a light, non-greasy feel.
Why It's Used: Used for its mixed wax-and-stearate glycerides; fossil wax character blended with stearic for softer consistency emollient properties; suitable for lightweight skin care where non-greasy texture is key.
How It Works: Ester of glycerol (branched or specialty alcohol) with montan wax fatty acids (c26-c34) and stearic acid (mixed glyceride blend); branching reduces crystallinity and greasiness; provides smooth, dry-oil skin feel.
