Product Overview
What Is PC30?
PC30 is a complex-type liquid preservative developed for cosmetic and personal care formulations. Its principal preservative components are Phenoxyethanol and Chlorphenesin. The supplied SDS also declares Water and Glycerin as components of the blend.
Two Complementary Preservative Ingredients
PC30 combines 68%–72% Phenoxyethanol with 19%–21% Chlorphenesin. The complementary action of these antimicrobial components helps disrupt microbial metabolism and inhibit microbial growth.
Because preservative performance changes with formula composition, pH, production hygiene, and packaging, we recommend validating PC30 in the complete finished product through compatibility, stability, and preservative efficacy testing.
By combining the two ingredients, PC30 provides broader antimicrobial coverage than either ingredient may provide alone.

Preservation Function
How PC30 Supports Product Preservation
Microbial contamination can affect the quality and safety of water-containing cosmetic products. PC30 combines two preservative components to support broader microbial control.
Gram-Positive and Gram-Negative Bacterial Control
PC30 supports control of common Gram-positive and Gram-negative bacteria found in cosmetic products.
Mold and Yeast Control
PC30 also provides mold and yeast control support, helping formulators build a broader preservation strategy than a bacteria-focused system alone.
Complementary Broad-Spectrum Protection
PC30 combines Phenoxyethanol and Chlorphenesin rather than relying on one preservative component. Their complementary antimicrobial action supports broad-spectrum protection through interference with microbial metabolism.
Product Benefits
Key Benefits of PC30
01
Broad-Spectrum Preservation Support
PC30 is designed to support control of common Gram-positive bacteria, Gram-negative bacteria, molds, and yeasts in one preservative blend.
This makes it relevant to skincare, cleansing, hair care, wet-wipe, and selected color-cosmetic formulations.
02
Wide pH Application Range
PC30 can be evaluated across pH 3–8, covering many acidic, mildly acidic, and near-neutral cosmetic systems.
The actual finished-product pH should remain stable during storage and should be included in preservative efficacy and stability testing.
03
Liquid Blend for Multiple Product Formats
We supply PC30 as a colorless to light yellow liquid. It can be added below 65°C and incorporated through the oil phase or dissolved in a compatible alcohol before addition.
The product can be evaluated in both leave-on and rinse-off formulations.
04
Free From Selected Preservative Classes
PC30 contains no parabens, slow-release formaldehyde preservatives, or methylisothiazolinone.
This supports formulation projects that specifically avoid those preservative classes while still requiring broad-spectrum microbial control.
Technical Specifications
PC30 Application-Specific Dosage Guide
We provide application-specific starting ranges for PC30 rather than recommending one fixed dosage for every formulation.
Application | Recommended Starting Level |
|---|---|
Creams and Lotions | 0.5%–0.8% |
Face Masks | 0.4%–0.6% |
Shower Gels and Shampoos | 0.5%–1.0% |
Serums and Toners | 0.5%–0.8% |
Color Cosmetics and Other Cosmetics | 0.5%–0.8% |
Wet Wipes | 0.5%–1.0% |
Other Product Categories | Contact us for project review |
Use these levels as starting points for formulation evaluation. We can help you select an initial dosage based on your product type, formula pH, process, and target market. Confirm the final dosage through compatibility, stability, safety, and preservative efficacy testing.
Market Applications
Typical Applications of PC30
Creams and Lotions
PC30 can be evaluated at 0.5%–0.8% in creams and lotions within pH 3–8. Confirm compatibility with the emulsion system, active ingredients, fragrance, and final packaging.
Face Masks
We recommend 0.4%–0.6% as a starting range for face-mask formulas. Test the complete mask essence together with the sheet material and final package.
Serums and Toners
PC30 can be evaluated at 0.5%–0.8% in serums and toners. For clear water-rich systems, check dissolution, clarity, color, odor, and long-term stability.
Shampoo and Shower Gel
The recommended starting range for shampoos and shower gels is 0.5%–1.0%. Confirm performance in the actual surfactant system and at the final product pH.
Wet Wipes
PC30 can be evaluated at 0.5%–1.0% in wet-wipe liquids. Preservative efficacy should be tested in the complete liquid, wipe substrate, and consumer package.
Color Cosmetics
We recommend 0.5%–0.8% for color cosmetics and other cosmetic formats. Evaluate compatibility with pigments, emulsifiers, oils, film-formers, and packaging.

- pH
- Color
- Odor
- Viscosity
- Clarity
- Precipitation
- Emulsion stability
- Packaging interaction
- Microbial quality
– Preservative efficacy
Packaging and Storage Guidance
Store PC30 in its sealed original HDPE packaging at 5–25°C, protected from direct sunlight. Keep containers upright and avoid rapid temperature fluctuations.
For raw-material storage and handling, avoid polyester or steel containers. Use our original HDPE packaging whenever possible.
Kind Tips
Formulation Precautions
pH Control
PC30 is recommended for pH 3–8. A broad pH range does not guarantee equal performance in every formula. Confirm efficacy at the actual finished-product pH.
Bioactive Compatibility
For formulas containing certain biological active ingredients, evaluate whether Phenoxyethanol could cause denaturation or other compatibility changes. This is particularly important for protein-, peptide-, enzyme-, or other biologically sensitive systems.
Production Hygiene
We recommend maintaining good raw-material control, clean equipment, and hygienic production conditions. Better hygiene can improve preservation performance in the finished product and may help reduce the required dosage.
Preservative Efficacy Testing
No preservative should be considered effective only because it is used within a recommended dosage range. Test PC30 in the final formula and final package.
Concentrated Raw-Material Safety
Avoid contact with the eyes, skin, and clothing. Use suitable personal protective equipment and refer to the current MSDS before handling.
Intended Use
PC30 is intended for cosmetic and industrial preservation applications. Do not use it for drug, medical, or related purposes.
No preservative should be considered effective only because it is used within a recommended dosage range. Test PC30 in the final formula and final package.
