Emulsifying wax Anionic

Emulsifying Wax Anionic is a versatile surfactant blend composed primarily of fatty alcohols (such as cetyl or stearyl alcohol) and anionic surfactants like sodium lauryl sulfate. It is designed to stabilize oil-in-water (O/W) emulsions by reducing interfacial tension between water and oil phases. It appears as white to off-white solid flakes or pellets, with a mild fatty odor and is dispersible in water with agitation and mild heat. Known for its excellent emulsification, cleansing, and thickening properties, this emulsifying wax is widely used in cosmetics, pharmaceuticals, household cleaners, and industrial applications.

Description

Emulsifying wax Anionic

Primary Uses 

 

  1. Cosmetics & Personal Care
  • Creams and Lotions: Used as a primary emulsifier in moisturizers, anti-aging creams, and sunscreens to stabilize oil-in-water emulsions and improve skin feel.
  • Hair Conditioners and Shampoos: Enhances product stability and foam generation while conditioning the scalp.
  • Cleansing Creams and Facial Washes: Provides mild cleansing action and creamy texture through its anionic surfactant content.
  • Deodorants and Antiperspirants: Assists in emulsifying oils and actives in stick or roll-on formulations.
  • Sunscreens: Helps evenly disperse and stabilize UV filters in the water phase for long-lasting protection.
  • Baby Products: Used in baby creams and gentle cleansers due to its mild, non-greasy emollient nature.

 

  1. Pharmaceuticals
  • Topical Creams and Ointments: Used in medicated formulations such as antifungals, corticosteroids, and anesthetics to stabilize emulsions and enhance spreadability.
  • Dermatological Preparations: Assists in even distribution of actives like salicylic acid, clotrimazole, and corticosteroids.
  • Ophthalmic and Nasal Creams: Facilitates drug delivery via semi-solid emulsions, ensuring better patient compliance and stability.
  • Transdermal Drug Delivery Systems: Supports emulsification of drug-loaded lipophilic and hydrophilic ingredients for absorption through skin.

 

  1. Household & Industrial Cleaning
  • Surface Cleaners: Used in floor and surface cleaning emulsions for dispersing oily residues.
  • Liquid Hand Soaps and Dishwashing Liquids: Adds viscosity and improves foaming action.
  • Laundry Pre-treatments: Stabilizes emulsions containing stain removers or fragrance oils.
  • Polish and Wax Emulsions: Stabilizes wax-based emulsions used for furniture and car polishes.

 

Secondary Uses 

 

  1. Food Industry (if food-grade variant)
  • Bakery and Confectionery: Acts as an emulsifier and stabilizer in icings, whipped toppings, and fillings (only when explicitly food-grade).
  • Nutraceutical Creams or Topicals: Used in topical delivery systems for fortified creams and lotions.

 

  1. Textile Industry
  • Textile Finishing Agents: Used as a softener base and emulsifier in finishing baths.
  • Wetting Agent: Promotes uniform dyeing during fabric processing.

 

  1. Paints, Coatings & Adhesives
  • Water-based Paints and Emulsions: Acts as a stabilizer and dispersant in pigment suspensions.
  • Adhesive Formulations: Maintains homogeneity and texture of adhesives containing both hydrophilic and lipophilic ingredients.

 

  1. Agriculture
  • Pesticide Formulations: Stabilizes emulsions in water-based pesticide sprays.
  • Fertilizer Blends: Ensures dispersion of nutrient oils or bioactive agents in aqueous solutions.
