Hydroxypropyl bis-palmitamide MEA is a synthetic pseudo-ceramide — a molecule engineered to mimic the shape and behavior of the skin’s own ceramides (two palmitic-acid “tails” on a hydroxypropyl-ethanolamine “head”) at a fraction of the cost and with greater stability. It was developed by Kao researchers after their foundational work showed that atopic dry skin is ceramide-deficient and that supplying ceramide-like lipids selectively restores the stratum corneum’s water-holding capacity [1]. Pseudo-ceramides of this class integrate into the barrier’s lipid lamellae alongside cholesterol and fatty acids, reduce water loss, and are used in Japanese barrier-repair skincare for dry and atopic skin [2, 3]. In haircare the same lipid-mimetic structure repairs the ceramide-depleted cuticle of bleached and heat-damaged hair, restoring smoothness and reducing breakage. It is oil-soluble, heat-stable, and compatible with cationic conditioners — an advantage over ORY®‘s anionic Ceramide Complex in BTMS systems.
What is Hydroxypropyl Bis-Palmitamide MEA made of?
Hydroxypropyl bis-palmitamide MEA is synthesized by reacting palmitic acid derivatives with a hydroxypropyl-ethanolamine backbone, giving a two-tailed amide lipid. Points to know [1–3]:
- Pseudo-ceramide structure: Two C16 palmitoyl chains + polar hydroxyl/amide head — mimics Ceramide 2 (NS) geometry and packs into lamellar lipid bilayers.
- Physical form: White waxy solid; melts ~90–100 °C; oil-soluble (dissolve in warm oil phase, esters, or with cholesterol/fatty acids).
- Stable: Heat-, pH- (3–9), and oxidation-stable; non-ionic — compatible with cationic (BTMS) and anionic systems.
- Physiologic pairing: Best with cholesterol and free fatty acids in roughly 3:1:1 ratio for barrier recovery [3].
- Typical use: 0.1–1% skincare; 0.05–0.5% haircare; 0.1–0.5% cosmetics.
What skin type is best suited for Hydroxypropyl Bis-Palmitamide MEA?
Hydroxypropyl bis-palmitamide MEA suits all seven ORY® skin types and is a barrier-repair specialist:
- Dry: Restores water-holding capacity in ceramide-deficient dry skin [1].
- Sensitive: Barrier repair for eczema-prone and reactive skin [2, 3]; non-irritating.
- Mature: Replaces age-depleted ceramides; reduces water loss and fine dehydration lines.
- Acne-prone: Non-comedogenic lipid; offsets barrier damage from acne actives.
- Oily: Low levels in light emulsions.
- Combination: Barrier support across zones.
- Normal: Preventive barrier maintenance; post-active recovery.
What hair type is best suited for Hydroxypropyl Bis-Palmitamide MEA?
The pseudo-ceramide repairs the cuticle’s lost lipid layer and works in cationic conditioners:
- Color-treated or chemically processed: The core use — replaces cuticle ceramides stripped by bleach and dye; reduces porosity and breakage.
- Dry or damaged: Restores cuticle lipids and smoothness after heat damage.
- Curly and coily: Seals the cuticle to hold moisture.
- Mature or thinning: Strengthens fragile fibers.
- Straight and wavy: Light repair in conditioners and leave-ins.
- Sensitive scalp, oily scalp, dandruff-prone: Fiber-focused; neutral for the scalp.
What are the benefits of Hydroxypropyl Bis-Palmitamide MEA?
The pseudo-ceramide’s benefits rest on foundational ceramide science [1–3]:
- Barrier repair: Ceramide-like lipids selectively restore water-holding capacity in dry, ceramide-deficient stratum corneum [1].
- Reduced water loss: Integrates into lipid lamellae with cholesterol and fatty acids [3].
- Atopic-skin support: Pseudo-ceramide products improve dryness and irritation in atopic-prone skin [2].
- Stability and cost: More stable and economical than natural ceramides.
- Cationic compatibility: Works in BTMS conditioners where anionic ceramide complexes cannot.
- Hair cuticle repair: Replaces lost cuticle lipids; smoother, stronger fiber.
- Cosmetic comfort: Barrier-supporting foundations and lip products.
- Post-active recovery: Restores the barrier after acids, retinol, and procedures.
Dual use across ORY® product lines
Hydroxypropyl bis-palmitamide MEA serves skincare, haircare (including cationic conditioners), and cosmetics; in cold-process soap it is wasted, but it survives in syndet and conditioner bars.

Pros and cons of Hydroxypropyl Bis-Palmitamide MEA
Pros
Cons
- Ceramide-mimetic with foundational science: [1–3].
- Stable, economical: Versus natural ceramides.
- Cationic-compatible: Conditioner-friendly.
- Skin and hair: Barrier and cuticle repair.
- Non-irritating: Suits atopic-prone skin.
- Synthetic: Not COSMOS-approved.
- High melting point: Requires hot oil-phase processing (~90 °C) or pre-dissolution in esters.
- Product-specific clinical data are limited: Evidence is on the pseudo-ceramide class and ceramide biology.
- Wasted in cold-process soap: Rinse-off/pH.
- Needs lipid partners: Pair with cholesterol and fatty acids for full barrier effect.
What is the best application of Hydroxypropyl Bis-Palmitamide MEA?
The pseudo-ceramide is built into barrier and repair products:

- Night cream: 0.3–0.5% with niacinamide (boosts ceramide synthesis).
- Hand cream: 0.5%.
- Conditioner or mask: 0.2–0.3% with BTMS for bleached or heat-damaged hair.
- Leave-in: 0.1–0.2%.
- Conditioner bar: 0.2–0.3%.
