33RD PARALLEL SOAP CO. Polysorbate 20 solubilizer — 8 oz USP-grade gentle emulsifier for essential oils & sprays

Polysorbate 20 is a USP-grade, liquid solubilizer and gentle emulsifier that blends essential oils and fragrances into water-based personal-care products for stable, clear results.

33RD PARALLEL SOAP CO.'s Polysorbate 20 (8 oz) is a versatile ingredient for formulators, DIY makers, and boutique brands. Sourced to USP standards and presented in resealable packaging, this liquid helps disperse oily actives into mists, shampoos, lotions, and sprays without cloudiness or separation. It’s derived from natural coconut sources and commonly used where a mild, non-irritating solubilizer is required.

How does Polysorbate 20 make oil-based scents and botanicals mix with water?

Polysorbate 20 acts at the interface between oil and water: its hydrophilic head bonds with water while the lipophilic tail associates with oils. This reduces surface tension and forms a stable, clear dispersion rather than visible droplets or a separated layer.

• Helps dissolve essential oils, fragrance oils, and certain botanical extracts into aqueous systems.
• Prevents hazing and oil separation in sprays and toners.
• Works well with light, low-viscosity carrier oils and volatile fragrance components.

What are practical usage rates and mixing tips for home and small-batch makers?

Start with a solubilizer-to-oil ratio between 1:1 and 2:1 (Polysorbate 20 : oil) for many fragrances and essential oils; stronger or heavier aromatic oils may need more. Pre-mix the oil and Polysorbate 20 thoroughly before slowly adding to the water phase while stirring to ensure clarity.

• Common starting ratio: 1–2 parts Polysorbate 20 to 1 part oil.
• For clear sprays, fully blend oil with Polysorbate 20 before adding to water.
• Use gentle stirring or a small immersion blender for uniform dispersions.

Is Polysorbate 20 safe for skin and what compatibility should I check?

This USP-grade Polysorbate 20 is derived from coconut and is widely used in cosmetics as a mild solubilizer and emulsifier. It’s generally well tolerated, but always perform a small patch test and follow regulatory labeling requirements for finished products. Compatibility checks with actives, preservatives, and pH-sensitive ingredients help ensure stability.

• Suitable for sensitive-skin formulas when used at recommended rates.
• Compatible with common cosmetic preservatives and surfactants; verify in final formula.
• Keep final product pH and preservative efficacy in mind during formulation.

How should I store and handle this 8 oz bottle for best results?

Store the bottle tightly sealed in a cool, dry place away from direct sunlight to preserve quality. The liquid consistency makes it easy to dispense; rinse droppers or tools between uses to avoid contamination. Resealable packaging helps maintain freshness for repeated small-batch production.

• Resealable bottle protects against moisture and contamination.
• Keep under typical room temperatures, away from heat sources.
• Label opened stock with date and batch notes for inventory control.

Who is this for: Small-batch formulators, indie skincare brands, aromatherapists, and DIY enthusiasts who need a reliable, gentle solubilizer to create clear, stable water-based products containing essential oils, fragrance blends, or light botanical oils. If you require a USP-grade, coconut-derived emulsifier to improve texture and visual clarity in sprays, toners, shampoos, and lotions, this 8 oz Polysorbate 20 is a compact, user-friendly option.
