Preparation, Characterization and Evaluation of Organogel-Based Lipstick Formulations: Application in Cosmetics

1,3:2,4-Dibenzylidene-D-sorbitol (DBS) and 12-hydroxystearic acid (12-HSA) are well-known as low-molecular-weight organogelators (LMOGs) capable of gelling an organic liquid phase. Considering their unique chemical physical properties, we assessed potential effects in new lipstick formulations by discrimination testing; vitro measurements the sun protection factor (SPF); thermal, mechanical texture analyzes. DBS 12-HSA were used to formulate four types lipsticks: L1 (1% DBS), L2 (10% 12-HSA), L3 (1.5% DBS) L4 (control, no LMOGs). The lipsticks tested for sensory perception with untrained panel 16 consumers. LMOG exhibited higher UVA (UVA-PF) SPF, particularly 12-HSA-based lipstick. Regarding thermal those without LMOGs more heat-amenable compared thermoresistant DBS-based lipsticks. results also showed viscoelastic thermally reversible properties effect increasing pay-off values. In general, analysis indicated that was significantly harder bend control, while other became softer easier throughout stability study. This work suggests use a structuring agent lipsticks, paving way towards photoprotective sustainable alternatives.
