Stearic Acid
Stearic Acid is a versatile and essential fatty acid widely used in various industries, including pharmaceuticals. It is a saturated fatty acid derived from natural sources like palm and coconut oils. STACLUB is 100% vegetable origin, NOT animal derived.
In its solid form, it appears as a white, waxy substance and is known for its stability and remarkable chemical properties. Our pharmaceutical-grade Stearic Acid meets the highest quality standards, ensuring it is free from impurities and contaminants.
