Description

Cetostearyl Stearate is a high-purity, synthetic ester derived from cetyl, stearyl, and stearic acids, functioning as a versatile emollient, opacifier, and consistency regulator. Its primary value lies in providing excellent skin feel, stability, and texture enhancement in formulations without greasiness. This makes it an essential ingredient for manufacturers in the cosmetics, personal care, and pharmaceutical industries seeking to create premium creams, lotions, and ointments.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emollient and opacifier in creams, lotions, and body butters to impart a rich, non-greasy texture and improve product stability.
• Pharmaceutical Topicals: Used as a consistency-giving agent and emollient in ointments, dermatological creams, and medicated pastes to enhance skin feel and drug delivery.
• Hair Care Products: Serves as a conditioning agent in hair creams, pomades, and treatments to provide manageability and a smooth feel without heavy residue.
• Makeup Products: Functions as a binder and texture modifier in foundations, lipsticks, and mascaras to ensure smooth application and consistent pigmentation.
• Industrial Lubricants & Release Agents: Employed in specialized formulations for plastics and metalworking where a non-toxic, stable lubricant is required.

Quality Control

Our Cetostearyl Stearate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant standards such as CTFA, USP/NF, and European Pharmacopoeia (Ph. Eur.) where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve quality and prevent rancidity. Keep away from strong oxidizing agents.
