Ethyl stearate CAS 111-61-5

What is Ethyl stearate CAS 111-61-5?

Ethyl stearate CAS 111-61-5 is a FEMA (3490) and JECFA (40) approved edible flavor, existing as a white crystalline mass with mild waxy odor and virtually odorless characteristic. As a natural fatty acid ethyl ester (FAEE) commonly found in vegetable oils, it is widely present in Jamaican rum, maple syrup, grapes, cognac, beef, cocoa and corn oil. Synthesized by esterification of ethanol with stearic acid (obtained from oleic acid hydrogenation), it exhibits antimicrobial activity and is a component of volatile oil from Rhododendron anthopogonoides. With stable physical and chemical properties under 2-8°C low-temperature storage, it is supplied in 99% high purity grade, widely applied in food, cosmetic, pharmaceutical and chemical synthesis fields.

Feature

1. Natural Flavor Compatibility – With mild waxy taste and mouthfeel, it is an ideal raw material for simulating honey and chocolate flavors, with good natural flavor matching and authenticity.
2. Approved Edible Spice Grade – Certified by FEMA and JECFA, compliant with food safety standards, and can be directly used in food flavor formulation.
3. Antimicrobial Activity – Exhibits certain antimicrobial properties, contributing to the preservation of products when used in food and cosmetic formulations.
4. Cosmetic Multi-effect Ingredient – Functions as emollient and perfuming ingredient in cosmetics, with excellent skin conditioning effect, keeping skin soft and moisturized.
5. Stable Physical and Chemical Properties – Stable under low-temperature storage, non-volatile, with good thermal stability, ensuring long-term effectiveness in product formulations.
6. High Purity Supply – Provided with 99% high purity grade, meeting the strict quality requirements of food, cosmetic and pharmaceutical fields.
7. Natural Occurrence in Multiple Substances – Widely found in fruits, beverages, meat and edible oils, with good biocompatibility and safety.
8. Versatile Synthesis Intermediate – Can be used to synthesize 1-octadecanol, stearic acid hydrazide and other fine chemicals, with diverse chemical reactivity.

Application

1. Food Flavor Formulation – Used in blending imitation honey, chocolate and other flavors requiring waxy taste or mouthfeel, applied in flavoring of candies, chocolate, baked food, beverages and dairy products, enhancing the richness and layering of flavors.
2. Cosmetic Production – Acts as emollient in skin care products (lotions, creams, lip balms) to improve skin moisturization and smoothness; serves as perfuming ingredient to add mild waxy notes, enhancing the sensory experience of cosmetics.
3. Pharmaceutical Field – Used as pharmaceutical excipient and formulation auxiliary material, compatible with most pharmaceutical ingredients, and can be used in the preparation of ointments, suppositories and other formulations; also serves as a reference substance in pharmaceutical research.
4. Chemical Synthesis – Serves as an important intermediate for the synthesis of 1-octadecanol, stearoylbenzoylmethane and stearic acid hydrazide, and is widely used in the production of fine chemicals and organic compounds.
5. Essential Oil and Spice Blending – Used in the blending of natural essential oils and synthetic spices, supplementing waxy notes, and enhancing the layering and stability of fragrance systems.
6. Daily Chemical Products – Added to detergents, soaps and other daily chemical products to improve product texture and skin compatibility, reducing irritation to the skin.
7. Biological and Agricultural Research – As a component of plant volatile oil with antimicrobial activity, it is used in the research of natural plant pesticides and biological preservatives.
