Glycerides, mixed C8-10 and succinyl (CAS 91744-56-8) — Citrus None Note Fragrance Ingredient
Glycerides, mixed C8-_10 and succinyl
CAS 91744-56-8
What Is Glycerides, mixed C8-_10 and succinyl?
Mixed C8-C10 glycerides with succinyl groups are synthetic emollients primarily used in cosmetic formulations. Consumers encounter them in moisturizers, lip balms, and skincare products where they help improve texture and spreadability. These ingredients matter because they create a non-greasy, silky feel while enhancing product stability without relying on petrochemical derivatives.
Safety Profile
GENERALLY SAFEWhat Does Glycerides, mixed C8-_10 and succinyl Smell Like?
This synthetic ingredient is odorless by design, serving purely functional purposes in formulations. Its lack of olfactory interference makes it valuable as a neutral base in fragrance-sensitive applications where texture modification is needed without altering scent profiles.
Chemistry, Properties & Perfumer Guide
The Chemistry
Mixed C8-C10 glycerides with succinyl groups are synthetic esters created through controlled esterification of medium-chain fatty acids (caprylic and capric) with glycerol, followed by succinylation. These modified triglycerides exhibit improved solubility and skin-feel properties compared to their unmodified counterparts. The succinyl groups introduce additional polar character, enhancing compatibility with both oil and water phases in emulsions.
