[Carnol as a stabilizer of the emulsion I system]

Area of Science:

• Cosmetic Science
• Colloid and Surface Chemistry

Context:

• Carnauba wax is a natural emulsifier.
• The insaponificable fraction of carnauba wax, known as Carnol, has potential applications in emulsion technology.
• Understanding the emulsifying properties of Carnol is crucial for developing stable cosmetic and pharmaceutical formulations.

Purpose:

• To evaluate the emulsified system stabilizing abilities of Carnol.
• To determine the optimal concentration of Carnol for creating stable oil-in-water (O/A) and water-in-oil (A/O) emulsions.
• To assess Carnol's performance in relation to the required hydrophilic-lipophilic balance (HLB) of a model emulsion system.

Summary:

• Carnol, the insaponificable fraction of carnauba wax, was investigated for its emulsifying capabilities.
• A model emulsion system with a required HLB of 9.0 was used for testing.
• 1% Carnol (w/v) produced A/O emulsions (HLB ≤ 7.0), while 2% Carnol stabilized O/A emulsions matching the system's HLB. 3% Carnol stabilized both emulsion types.

Impact:

• Carnol demonstrates versatile emulsifying properties, adaptable to different formulation needs.
• This research highlights Carnol as a viable natural ingredient for stabilizing various emulsion types.
• The findings support the use of Carnol in cosmetic and pharmaceutical industries for creating stable emulsions.
