Retinoid color stability chemistry: UnileverRecent Research Landscape

Oxidative degradation of oil-continuous matrices causes unsightly discoloration that leads to product rejection. These innovations utilize indole-based chemical species to inhibit chromophore formation and maintain aesthetic consistency.

What technical problems is Unilever addressing in Retinoid color stability chemistry?

Photoinduced oxidative pigment degradation

(4)evidences

Retinoid compounds undergo rapid chemical degradation when exposed to air or light, resulting in undesirable color shifts in cosmetic products. Preventing this aesthetic and chemical instability ensures product shelf-life and consumer acceptance.

Retinoid induced oxidative discoloration

(4)evidences

Retinoic acid precursors undergo rapid chemical instability leading to undesirable aesthetic changes in formulations. Preventing this discoloration ensures product shelf-life and consumer acceptance.

Oxidative lipid degradation

(1)evidences

Retinoids lose biological activity and change color when exposed to light and oxygen. Preventing this breakdown ensures product efficacy and aesthetic shelf-life.
