Retinaldehyde Liposome Liquid

Retinal made easy to formulate

Retinaldehyde, listed on labels as Retinal, is the vitamin A aldehyde that sits one step closer to retinoic acid than retinol in the skin's own conversion chain. As a raw powder it is sensitive to light, air and heat, and it does not dissolve in water. This liquid places it inside nano-sized phospholipid liposomes so the active disperses through a water-based serum and is better shielded during processing.

Composition

The INCI is Aqua, Phospholipids, PEG-20, Caprylic/Capric Glycerides, Retinal. The phospholipids build the vesicle wall, the glycerides form a light lipid core for the retinal and PEG-20 helps the dispersion stay uniform. Lot data appear on the certificate of analysis.

Product ideas

Retinal liquids are chosen for night serums, renewal creams, eye creams and neck care positioned for a smoother, more refined and more even look. Brands that already sell encapsulated retinol often add retinal as a step-up product, while a plant alternative for sensitive lines is bakuchiol.

How to work with it

Process

Add the liquid during cool-down below 40 °C with low shear, ideally under yellow or dim light, and fill into opaque, airless packaging. Hold the finished pH roughly between 5 and 6.5 and include an antioxidant such as tocopherol in the oil phase.

Packs and storage

Sold in 50 g, 100 g and 250 g packs (1.76, 3.5 and 8.8 oz). Store tightly closed in the refrigerator, away from light and air.
