DEVELOPMENT OF LIPSTICK PRODUCTS FROM CAESALPINIA SAPPAN LINN AND COCOA USING LOCAL RESOURCES AND INNOVATION UNDER THE TALENT MOBILITY CONCEPT: A CASE STUDY OF BRIGHT-UP COMMUNITY ENTERPRISE, KAMPHAENG PHET

Abstract

This study aimed to determine suitable conditions for extracting bioactive compounds from Caesalpinia sappan Linn., to develop natural extract-based lipstick products, and to examine community enterprise reflections on the development process, employing a mixed-methods research design. Participants were 40 product users and 7 members of the Bright-Up community enterprise.
The instruments included a chemical laboratory kit, a UV–visible spectrophotometer, questionnaires, and interviews, and were analyzed using both quantitative and qualitative approaches. The findings showed that Caesalpinia sappan Linn. is a rich source of phenolic and flavonoid compounds, which function as natural colorants and antioxidants. Water extraction at a 100:0 ratio for 10 min yielded the highest total phenolic content, 3,510 mg GAE/100 g dry weight, whereas extraction for 20 min produced the highest flavonoid content, 1,429 mg CE/100 g dry weight. The resulting lipstick exhibited a natural pink shade and acceptable lip-care properties. Consumer evaluations indicated a high level of satisfaction with both lip balm and lip gloss product types ( = 3.97), with color and texture as the most preferred attributes. Interview reflections showed that Bright-Up members gained knowledge of scientific extraction, quality control, and marketing. Talent Mobility implementation enabled innovation-based product development grounded in local resources and wisdom, supporting value chain and circular economy practices. This study recommends improving the stability of natural colorants and developing durable, eco-friendly packaging. It also underscores the importance of community-based raw material sourcing to enhance cost efficiency and the sustained operation of the Talent Mobility mechanism through collaboration among universities, communities, and government agencies. Future study should incorporate social return on investment (SROI) assessment to determine the long-term developmental value and sustainability of community enterprise initiatives.
