Development, formulation, and effectiveness testing of a silicone-based barrier-type hand cream

Area of Science:

• Dermatology
• Cosmetic Science
• Materials Science

Background:

• Severely damaged skin requires specialized care.
• Traditional water-in-oil (W/O) emulsions often face challenges with consumer acceptance due to their texture and feel.
• Developing effective and acceptable barrier creams is crucial for managing compromised skin conditions.

Purpose of the Study:

• To develop and test a hydrating, nutritive, barrier-type hand cream for severely damaged skin.
• To optimize organoleptic properties of a W/O silicone emulsion for enhanced consumer acceptance.
• To evaluate the effectiveness and acceptability of the developed hand cream formula.

Main Methods:

• Formulation development utilizing silicone derivatives and a W/O silicone emulsifier.
• Pharmacotechnical testing for formula stability and preservation.
• Effectiveness and user acceptability testing on individuals with severely damaged skin.

Main Results:

• Pharmacotechnical tests yielded optimal results, confirming formula stability and preservation.
• The developed hand cream demonstrated effectiveness in improving dry skin conditions.
• Users reported significant subjective improvements in skin cracking and scaling, indicating high acceptability.

Conclusions:

• The developed hydrating, barrier-type hand cream is pharmacotechnically optimal and well-accepted by users.
• The formulation effectively addresses severely damaged skin, including symptoms like cracking and scaling, without specific dermatological active ingredients.
• The study highlights the potential of optimized W/O silicone emulsions in skincare for compromised skin.
