Ammonium Lactate
Ammonium Lactate is the ammonium salt of lactic acid, appearing as a clear, hygroscopic liquid or syrupy solution. It is widely used in pharmaceutical, cosmetic, and food industries primarily for its moisturizing, pH adjusting, and antimicrobial properties. In topical formulations, it acts as a keratolytic agent to help exfoliate and hydrate skin, making it popular in treatments for dry, scaly, or ichthyotic skin conditions. Its biocompatibility and mild acidic nature make it a versatile ingredient in various industrial and personal care products.
Capsicum Oleoresin Liquid
Capsicum Oleoresin Liquid is a concentrated extract derived from the dried fruits of Capsicum annuum or Capsicum frutescens (chili peppers). It is a dark red to brownish oily liquid containing approximately 8% capsaicinoids—primarily capsaicin and dihydrocapsaicin—which are the primary pungent components. This oleoresin is widely used for its flavoring, coloring, medicinal, and irritant properties in the food, pharmaceutical, veterinary, and defense industries. It is produced by solvent extraction followed by standardization to achieve consistent pungency levels. The product is highly potent and must be handled with care due to its intense irritant nature.
