Frequently Asked Questions

Everything you need to know about our products and services.

What are isothiazolinones used for?

Isothiazolinones are broad-spectrum biocides used as preservatives in water-based systems including paints, coatings, adhesives, industrial fluids, and personal care products. They prevent microbial growth and spoilage.

Are your products formaldehyde-free?

Yes, we specialize in environmentally friendly and formaldehyde-free preservation technologies. Our product range includes multiple formaldehyde-free alternatives for various applications.

Can I use PHMB in cosmetic formulations?

Yes, PHMB (Polyhexamethylene Biguanide) is approved for use in cosmetic products at concentrations below 0.3%. It's commonly found in skin care, makeup, eye-care solutions, and wound care products.

What is the difference between BIT and MIT?

BIT (Benzisothiazolinone) and MIT (Methylisothiazolinone) are both isothiazolinone biocides. MIT is more water-soluble and often used in combination with BIT for synergistic effects. MIT has higher biocidal activity but may require careful formulation for certain applications.
