On May 6, 2026, new achievements in the technical analysis of beauty raw materials were released. As a core auxiliary material for rheology control in cosmetics, thickeners not only adjust viscosity but also undertake key functions such as stabilizing systems, suspending particles and optimizing skin feel. Their selection directly determines product quality. At present, mainstream thickeners in the industry are divided into six categories. Acrylic acid thickeners have high transparency and thickening efficiency, suitable for transparent gels. Natural polymer gums have strong salt tolerance, ideal for particle-containing formulas. Cellulose thickeners with smooth skin feel are mostly used in low-viscosity lotions. Inorganic clays excel in powder suspension, often applied in sunscreens and cosmetics. New synthetic polymer thickeners resist acid and alcohol, meeting high-efficacy formula needs. Starch and oil systems are suitable for ointments and color cosmetics. Industry trends show that binary/ternary compound thickening has become mainstream, the application of natural thickeners continues to rise, and acid and alcohol resistant products are preferred for special efficacy formulas. Scientific selection and compounding can achieve the best matching of rheology, skin feel and system, promoting the high-quality development of cosmetic formulas.
