1️⃣ What is Glycerin?

Glycerin (glycerol) is a colorless, odorless, sweet, hygroscopic liquid alcohol.

Why it matters:

• Safe (food & pharma grades)

• Water-soluble

• Excellent humectant (retains moisture)

• Biodegradable & renewable when palm-based

👉 Palm oil is the largest renewable source of glycerin globally.

---

2️⃣ Where Glycerin Comes From (Palm Value Chain)

Glycerin is not the main product—it is a by-product from two major processes:

A. Fat Splitting (Hydrolysis) – Oleochemical Route

Palm / PK Oil + Water → Fatty Acids + Glycerin

B. Transesterification – Biodiesel Route

Palm Oil + Methanol → Methyl Ester (Biodiesel) + Glycerin

👉 About 10% by weight of oil becomes glycerin.

Output:

• Fatty acids / methyl ester (main product)

• Sweet water containing glycerin

---

② Sweet Water Concentration

• Glycerin content: 10–20%

• Multi-effect evaporators remove water

• Produces crude glycerin (80–88%)

---

③ Glycerin Distillation

• Vacuum distillation

• Removes:

  • Salts

  • Methanol

  • Color bodies

  • Odor compounds

---

④ Polishing & Refining

Depending on grade:

• Ion exchange

• Carbon treatment

• Fine filtration

---

5️⃣ Glycerin Grades from Palm Oil

Grade	Purity	Main Uses
Crude glycerin	80–88%	Industrial, energy
Technical grade	95–98%	Chemicals, resins
USP / Pharma grade	≥99.5%	Medicine, cosmetics
Food grade	≥99.5%	Food & beverage

👉 Higher purity = much higher value

---

6️⃣ Mass Balance (Rule of Thumb)

From 1,000 kg palm oil:

• Fatty acids / biodiesel: ~900 kg

• Glycerin: ~100 kg

After refining:

• ~85–90 kg refined glycerin

🧠 Final Takeaway

Palm oil doesn’t just feed the world—it hydrates it, heals it, and cleans it through glycerin.

From cooking oil → chemistry → medicine → daily life

Here’s a clear, data-backed overview of global glycerin demand by industry — showing which sectors consume glycerin and why it matters for the palm oil and oleochemical value chain:

---

🌍 Global Glycerin Demand by Industry

Glycerin (glycerol) is a versatile chemical produced mainly as a co-product from:

• biodiesel production

• oleochemical splitting of fats/oils
  Palm-based glycerin is a major part of the global supply because palm oil and palm kernel oil are widely processed worldwide. 

Below are the key demand segments and their relative importance:

---

1️⃣ Personal Care & Cosmetics

💧 Largest single global segment (~30–40%+)

• Used as a humectant, emollient, moisturizer, and solvent

• Found in lotions, creams, shampoos, soaps, toothpaste, deodorants, etc.

• Rising demand tied to natural and plant-based formulations. 

👉 This segment typically accounts for ≈30–42% of global glycerin use.

---

2️⃣ Pharmaceuticals & Healthcare

💊 Major growing segment (~20–25%)

• Used as solvent, sweetener, excipient, and stabilizer

• Common in cough syrups, capsules, ointments, wound care products

• Pharmaceutical grade glycerin demand is increasing with stricter purity requirements. 

👉 Around 20–25% of glycerin goes into medical and healthcare uses.

---

3️⃣ Food & Beverages

🍭 Significant demand (~15–30%)

• Functions as a humectant, sweetener, and texture enhancer

• Used in bakery goods, confectionery, beverages, low-sugar products

• Recognized as safe by regulators such as the FDA. 

👉 Shares vary by report source but often fall in the 15–30% range.

---

4️⃣ Industrial & Chemical Applications

🏭 Important segment (~10–15%)

• Feedstock for derivatives such as propylene glycol, epichlorohydrin, solvents, resins

• Used in adhesives, antifreeze, plastics, coatings, and rubber. 

👉 Industrial uses typically represent ≈10–15% of total glycerin consumption.

---

5️⃣ Biodiesel / Biofuels (Indirect demand)

⚡ Driven by production, not direct use

• Glycerin itself is a by-product of biodiesel (FAME) manufacture

• Biodiesel output contributes significantly to glycerin supply (≈60% from biodiesel pathways) — this boosts supply rather than direct end-use demand. 

👉 While this isn’t a direct demand sector, it fundamentally shapes global glycerin availability and pricing.

---

📊 Approximate Breakdown (Typical Range)

Here’s a consolidated, approximate view of how glycerin demand is distributed globally:

Sector	Typical % of Total Glycerin Demand
Personal Care & Cosmetics	~30–40%
Pharmaceuticals & Healthcare	~20–25%
Food & Beverages	~15–30%
Industrial & Chemical	~10–15%
Other (emerging uses)	~5%

Note: Actual market share can vary by region and reporting source, but most credible market analyses align with this broad distribution.
