Stability of a Natural-Based Cream Containing Lecythis pisonis Extract

Area of Science:

• Cosmetic Science
• Natural Product Chemistry
• Pharmacognosy

Background:

• Outer pericarps of Lecythis pisonis are agricultural by-products rich in antioxidant compounds.
• Natural ingredients are increasingly sought after in cosmetic formulations for their potential health benefits.
• Assessing the stability and compatibility of botanical extracts in cosmetic bases is crucial for product development.

Purpose of the Study:

• To evaluate the incorporation of Lecythis pisonis pericarp extract into an all-natural cosmetic formulation.
• To assess the physical-chemical, organoleptic, and microbiological stability of the formulation containing the extract.
• To determine the impact of extract concentration on the formulation's stability and safety.

Main Methods:

• Preparation and characterization of Lecythis pisonis pericarp extract.
• Formulation of an all-natural cream base incorporating varying concentrations of the extract.
• Evaluation of physical-chemical parameters (e.g., pH, viscosity) and organoleptic properties (e.g., color, odor).
• Microbiological challenge tests and stability studies under defined conditions.

Main Results:

• The cosmetic formulation with Lecythis pisonis pericarp extract showed no significant alterations in physical-chemical or organoleptic parameters post-stability testing.
• Increased concentrations of the extract led to a higher degree of formulation instability.
• The extract demonstrated compatibility with the cream base, but concentration is a critical factor for stability.

Conclusions:

• Lecythis pisonis pericarp extract can be incorporated into natural cosmetic formulations.
• Careful control of extract concentration is necessary to maintain product stability and quality.
• The developed natural formulation meets regulatory standards and possesses an effective preservation system.
