Common Name(s): Retinyl soyate

DESCRIPTION

What It Does: Provides stable vitamin a skin renewal with improved oxidative stability from soy fatty acid esterification.

Why It's Used: Used as a stabilized retinol ester with soybean oil fatty acid groups providing added skin-compatibility.

How It Works: Retinyl soyate = retinol esterified with soybean oil fatty acids (linoleic/oleic dominant); the polyunsaturated soy fatty acid ester groups may paradoxically provide some oxidative protection via their tocopherol-like activity.

Typically Found In: Anti-aging serums,stable retinol formulas

SOURCING & ETHICS

Vegan Status: Conditional - feedstock declaration required

Halal Status: Unverified - feedstock declaration required (plant, animal and petrochemical routes all exist)

Source Notes: Retinol ester with soybean (glycine max) oil fatty acids; semi-natural. [audit 2026-07-29 rev2: origin-dependent: the same inci exists in plant, animal and petrochemical versions and the name does not discriminate. determination requires shariah-panel sign-off.]

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Safety Profile: Good safety profile. ewg score: 1–2.

Works Well With: Vitamin c,niacinamide

Avoid Combining With: Avoid with other retinoids; use spf

SCIENTIFIC NOTE

Retinol esters with plant oil fatty acids provide improved stability vs pure retinol; retinyl linoleate/oleate from soy is hydrolyzed to retinol by skin esterases.
