Product Overview
What Does Quaternium-73 Do?
Quaternium-73, also known as Pionin, is a low-use-level antimicrobial cosmetic ingredient mainly used in formulations for oily and blemish-prone skin. Our Quaternium-73 has an assay specification of ≥99.0% by HPLC and a recommended starting level of 0.001–0.005%. It is suitable for toners, serums, gels, cleansers, masks and other formulations where antimicrobial support and low active loading are important.
01
Low-Dose Antimicrobial Active
Quaternium-73 works at a very low formulation level, making it useful when formulators want to introduce antimicrobial functionality without adding a large amount of active material.
02
Relevant to Blemish-Prone Skin
Our available test data include activity against multiple microorganisms, including C. acnes, supporting the evaluation of Quaternium-73 in products developed for oily, blemish-prone and clearer-looking skin.
03
Formulation Requires Proper Incorporation
Because Quaternium-73 has limited water solubility, we recommend premixing it in a suitable medium such as Butylene Glycol, Propylene Glycol, 1,2-Pentanediol or Ethanol before adding it to the main batch, followed by compatibility and stability testing.
Applications
Where Quaternium-73 Fits Best
Quaternium-73 is best suited to low-dose oily-skin and blemish-care formulations, particularly where antimicrobial support is needed without significantly increasing the total active load. Its 0.001–0.005% recommended starting level makes it practical across both leave-on and rinse-off formats.
Toners, Essences & Serums
Lightweight leave-on systems are a strong fit for Quaternium-73. Its low use level works well in formulas designed for oily and blemish-prone skin, while clarity, dissolution and color stability can be monitored easily during development.
Gels & Targeted Blemish Care
Quaternium-73 can be incorporated into gels and targeted treatment-style cosmetic formats where formulators want concentrated blemish-care positioning without adding a high active load. Premixing and light stability should be confirmed before scale-up.
Cleansers & Masks
Quaternium-73 can also be evaluated in cleansing and mask systems. In these formats, compatibility with surfactants, the preservation system and the intended contact time becomes more important than simply achieving dissolution.

Frequently Asked Questions
Questions from Formulators and Buyers
- What is Quaternium-73?
Quaternium-73, also known as Pionin, is a low-use-level antimicrobial cosmetic ingredient mainly used in formulations for oily and blemish-prone skin. Its CAS number is 15763-48-1.
- What are the main benefits of Quaternium-73?
Its main value is antimicrobial support at a very low use level. This makes Quaternium-73 particularly relevant to oily-skin and blemish-care formulations where formulators want effective functionality without adding a high active load.
- Can Quaternium-73 be used for acne-prone skin?
Yes. Quaternium-73 is commonly evaluated in cosmetic formulations for oily and blemish-prone skin. Our available test data include activity against C. acnes, supporting its use in blemish-care formulation development.
- What is the purity of Noyain Quaternium-73?
Our Quaternium-73 specification requires an assay of ≥99.0% by HPLC. For purchasing evaluation, you can request the applicable batch COA to review the actual batch quality data.
- What is the recommended use level?
We recommend 0.001–0.005% as a starting range for formulation development. The final dosage should be confirmed according to the complete formula, target market, safety assessment and stability results.
- Is Quaternium-73 water soluble?
Quaternium-73 has limited water solubility. We recommend premixing it in a suitable medium such as Butylene Glycol, Propylene Glycol, 1,2-Pentanediol or Ethanol before adding it to the main batch.
- What are the safety considerations for Quaternium-73?
Quaternium-73 should be used at an appropriate concentration in a properly assessed finished formulation. Safety depends on the use level, complete formula, product format and target-market requirements, so finished-product safety assessment is still required.
