Understanding Perbedaan Citric Acid Monohydrate dan Anhydrous

Citric acid monohydrate and anhydrous variants differ primarily in crystalline water content. Monohydrate contains 7.5-9% bound water, while anhydrous has ≤0.5% moisture. This distinction impacts solubility rates (monohydrate dissolves 59g/100ml at 20°C vs. 73g/100ml for anhydrous) and thermal stability. Pharmaceutical manufacturers prefer anhydrous for moisture-sensitive formulations, whereas food processors often choose monohydrate for controlled acidulation.

Technical Specifications and Performance Metrics

Comparative analysis reveals critical stability variations:

Parameter	Monohydrate	Anhydrous
Melting Point	153°C	156°C
pH (1% solution)	2.2	2.1
Shelf Life	24 months	36 months
Bulk Density	0.67 g/cm³	0.82 g/cm³

Manufacturer Quality Comparison

Leading suppliers exhibit distinct profiles:

Vendor	Purity	GMP	Halal Cert.	MOQ
Supplier A	99.8%	Yes	No	500kg
Supplier B	99.5%	No	Yes	1MT
Supplier C	99.9%	Yes	Yes	5MT

Customized Solution Development

Tailored formulations address specific industry requirements:

• Pharma-grade anhydrous citrate with ≤10ppm heavy metals
• Food-grade monohydrate blends with 2-5% silica flow agents
• Cosmetic complexes combining citrates with 15-20% glycol carriers

Application Performance Data

Beverage acidulant trials showed monohydrate delivered 12% longer shelf life than anhydrous in pH 3.2 formulations. Pharmaceutical tablet compression tests revealed anhydrous citrate maintained 98% potency after 6 months vs. 93% for monohydrate under accelerated stability conditions (40°C/75% RH).

Propylene Glycol vs. Dipropylene Glycol Characteristics

Property	PG	DPG
Viscosity (25°C)	56 mPa·s	110 mPa·s
Boiling Point	188°C	232°C
Flash Point	99°C	124°C
Humectancy	63% RH	41% RH

Optimizing Perbedaan Citric Acid Monohydrate dan Anhydrous Selection

Final product requirements dictate optimal citrate form selection. For high-moisture systems (>5% H₂O), monohydrate demonstrates 18% better solubility kinetics. In contrast, anhydrous citrate improves tablet hardness by 22% in dry compression processes. Glycol selection follows similar logic - PG for rapid solvation needs vs. DPG for sustained-release formulations requiring higher thermal stability.

FAQS on perbedaan citric acid monohydrate dan anhydrous

Q: What is the main difference between Citric Acid Monohydrate and Anhydrous?

A: The key difference lies in water content: Citric Acid Monohydrate contains one water molecule per citric acid molecule, while the Anhydrous form is water-free. This affects their stability, shelf life, and suitability for specific applications like food preservation or pharmaceuticals.

Q: How do Propylene Glycol and Dipropylene Glycol differ chemically?

A: Propylene Glycol (PG) has a single molecule with two hydroxyl groups, whereas Dipropylene Glycol (DPG) consists of two PG molecules linked by an ether bond. This structural difference impacts their viscosity, solubility, and use in cosmetics or industrial products.

Q: When should I use Citric Acid Monohydrate vs. Anhydrous?

A: Monohydrate is preferred in food and beverages where controlled moisture is acceptable, while Anhydrous is ideal for moisture-sensitive processes, such as dry powder formulations or long-term storage.

Q: Are Propylene Glycol and Dipropylene Glycol interchangeable in industrial applications?

A: No—PG is more hygroscopic and suited for antifreeze or humectants, while DPG’s lower volatility and milder odor make it better for fragrances, lubricants, or specialty solvents.

Q: Does water content affect Citric Acid shelf life?

A: Yes. Anhydrous Citric Acid has a longer shelf life in dry environments, whereas Monohydrate may clump or degrade faster in humid conditions, requiring airtight storage.
