Description

What is Hydrogenated Lecithin?

Hydrogenated Lecithin (INCI: Hydrogenated Lecithin; CAS 92128-87-5) is a purified, hydrogenated mixture of phospholipids, most commonly derived from soybeans, supplied as light yellow waxy pellets or a powdery solid. Hydrogenation removes unsaturated bonds, giving the ingredient excellent oxidative stability while preserving the natural, skin-identical structure of phospholipids. It functions as a mild emulsifier and a liposome-forming agent, improving the stability of emulsions and enhancing the skin affinity of finished products. Thanks to its unique powdery texture, it makes serums and sunscreens feel softer, smoother and less sticky, and it supports the delivery and controlled release of actives.

Key Benefits

• Improves formulation stability: acts as a mild emulsifier and stabilizer in both creams and dispersed systems.
• High skin affinity: phospholipids resemble the lipids of the skin barrier, supporting compatibility and comfort.
• Liposome-forming: builds vesicular structures that encapsulate and deliver actives with controlled release.
• Unique powdery texture: gives serums and sunscreens a softer, lighter, less sticky after-feel.
• Oxidatively stable: hydrogenation makes it more resistant to rancidity than unhydrogenated lecithin.
• Mild and skin-friendly: suitable for sensitive skin and gentle, high-end formulations.
• Versatile carrier: supports both water- and oil-soluble actives in a wide range of product types.

Applications

• Serums and essences: liposomal and phospholipid-based serums with a smooth, elegant feel.
• Sun care: sunscreens and SPF products that glide on and feel less sticky.
• Face and body care: moisturizing creams, lotions, balms and treatment products.
• Wash products and color cosmetics: mild cleansers, foundations and emulsified makeup.
• Delivery systems: liposomes and vesicular carriers for sensitive or high-value actives.

Typical use level: 0.5–5%, depending on the formulation and desired effect.

FAQ

Q1: What is the difference from ordinary lecithin? A1: Hydrogenated lecithin is chemically stabilized by hydrogenation, so it resists oxidation and odor development while retaining the phospholipid benefits.

Q2: How does it form liposomes? A2: When hydrated and properly processed, its phospholipids self-assemble into concentric bilayer vesicles that can encapsulate actives.

Q3: Why is it used in serums and sunscreens? A3: Its phospholipid structure boosts skin affinity, while its powdery texture makes these products feel softer and less sticky.
