Chemical Structure

Basic Info

Zinc Ricinoleate (CAS Registry Number: 13040-19-2), chemically defined as the zinc salt of ricinoleic acid, is a high-performance, plant-derived odor-absorbing agent synthesized from purified castor oil fatty acids and zinc oxide. Appearing as pale yellow flakes, granules, or pastilles with a faint characteristic fatty odor, this functional ingredient has become a cornerstone raw material for modern personal care, household care, and industrial odor-control formulations.

Unlike traditional masking fragrances that merely cover unpleasant smells or aluminum salts that block sweat glands, Zinc Ricinoleate operates through a selective chemical fixation mechanism. When incorporated into an emulsion or surfactant system, the zinc atom acts as a nucleophilic trap that chemically binds with low-molecular-weight volatile organic compounds (VOCs)—specifically sulfur-containing compounds (mercaptans, hydrogen sulfide) and nitrogen-based odors (ammonia, amines). This reaction forms stable, non-volatile, odorless complexes without disrupting the natural skin flora or inhibiting normal perspiration.

At Shandong Zhishang Chem Co., Ltd., our Zinc Ricinoleate is manufactured through controlled saponification and precipitation processes to deliver consistent melting behavior, low free fatty acid content, and reliable batch-to-batch performance for global formulators.

Product Packaging

Zinc Ricinoleate Application

Zinc Ricinoleate combines gentle skin compatibility with robust odor-neutralizing efficiency, making it suitable across multiple commercial sectors:

Personal Care Deodorants: Widely used in aluminum-free roll-ons, deodorant sticks, foot creams, and body sprays to neutralize body odor without affecting natural skin physiology.

Household and Air Care Products: Formulated into fabric refresher sprays, carpet deodorizers, kitchen waste bin sprays, and bathroom air neutralizers to eliminate cooking, smoke, and mildew odors.

Pet Care Formulations: Incorporated into pet shampoos, coat sprays, and cat litter additives to safely bind ammonia and organic pet odors without irritating animal skin.

Industrial and Textile Auxiliaries: Utilized in footwear insoles, functional textile finishes, and waste management facilities to control persistent industrial malodors.

FAQ

Q1: How do I properly dissolve Zinc Ricinoleate into water-based or surfactant formulations?

A1: Zinc Ricinoleate is insoluble in cold water and requires hot-process incorporation. Heat the oil phase or non-ionic/anionic surfactant phase to 75°C–80°C until the flakes melt completely into a clear liquid, then homogenize into the water phase under steady agitation. Avoid pairing it directly with strong cationic surfactants, as ionic incompatibility may reduce clarity.

Q2: What is the recommended usage level for Zinc Ricinoleate in finished products?

A2: Typical inclusion rates range from 0.5% to 3.0% by weight depending on the application. Personal care roll-on deodorants generally utilize 1.0% to 2.5%, while household fabric sprays and pet care products perform effectively at 0.5% to 1.5%.

Q3: Can Zinc Ricinoleate be combined with essential oils or fragrances?

A3: Yes. It demonstrates excellent compatibility with most fragrance oils and botanical extracts. Because it traps volatile malodor molecules rather than reacting with standard fragrance aldehydes or esters, it allows lower fragrance dosages to perform more cleanly.

Q4: What packaging options and shelf life apply to bulk orders from Shandong Zhishang Chem?

A4: Standard export packaging consists of 25 kg multi-wall kraft paper bags or 25 kg fiber drums lined with moisture-barrier polyethylene inner bags. When stored in a cool, dry warehouse below 30°C away from direct sunlight, the product maintains full specification stability for 24 months.

Regulatory Compliance and Quality Certifications

To ensure seamless customs clearance and formulation approval across North American, European, and Asian markets, Shandong Zhishang Chem operates under strict international quality frameworks:

ISO 9001:2015 Certified Production: Full batch traceability from castor seed fatty acid refinement through final flake packaging.

EU REACH Registration Support: Complete technical dossiers and supply chain documentation available for European Union importers and downstream cosmetic manufacturers.

Cosmetic GMP Alignment (ISO 22716): Manufactured in clean, controlled environments to prevent cross-contamination and maintain low microbial counts.

Plant-Derived & Vegan Profile: Sourced from renewable castor oil derivatives, supporting clean-label, aluminum-free, and cruelty-free product positioning.

In-House Quality Assurance and Batch Verification

Because Zinc Ricinoleate has a high melting point and specific surfactant solubility requirements, inconsistent zinc ratios can cause recrystallization or phase separation in finished creams and roll-ons. Every batch produced at our facility undergoes a four-point analytical inspection before Certificate of Analysis (COA) release:

Complexometric EDTA Titration: Precisely determines elemental zinc content (9.5%–11.0%) to verify complete salt formation and optimal odor-binding capacity.

Capillary Melting Point Determination: Confirms uniform thermal transition between 70°C and 80°C, ensuring predictable melting behavior during hot-process emulsification.

Potentiometric Acid Value Testing: Monitors unreacted ricinoleic acid levels (below 15.0 mg KOH/g) to prevent unwanted viscosity shifts in customer emulsions.

ICP-OES Trace Metal Screening: Verifies that lead, arsenic, mercury, and cadmium remain strictly below international cosmetic safety thresholds.
