In-can preservation 

At Corbion, we know how important it is to protect your household cleaning products with in-can preservatives. But we believe there’s a greener, safer way of doing it.

Lactic acid is an emerging ingredient for in-can preservation that is an easy-to-use, label-friendly and safe alternative for formulators. As a preservative, Corbion’s lactic acid for in-can applications – PURAC^® Sanilac – offers compatibility with other common detergent ingredients, including surfactants and alcohols. In fact, when added to a formulation with chelating agents and alcohols (like IPA), its performance as a preservative is boosted; offering potent efficacy and powerful biobased in-can preservation in cleaning and personal care formulations with low pH conditions.  

Biocide replacements

Chemical biocides, like isothiazolinones, are a popular preservative even today. But that protection comes at a cost. There has been growing concern regarding their safety, with skin sensitization being a significant side-effect of their use. These concerns are most acute in fabric conditioning and cosmetic applications, where allergenic chemicals stay in contact with the skin for prolonged periods of time. This has led to new regulations regarding isothiazolinone use in some homecare and personal care products.

At the same time, shoppers worldwide are showing a preference for eco-friendly and green products, even within the household and personal care categories. This is causing a shift in demand away from products containing chemical-based, non-biodegradable ingredients, leading to the emergence of isothiazolinone biocide replacements in the market, and a rise in MIT and BIT alternatives.

Because PURAC^® Sanilac is derived from L(+) lactic acid, which is produced by the skin naturally, it is skin-friendly and does not cause sensitization like isothiazolinone biocides, making it an attractive option for formulators looking to go safer and greener.

PURAC^® Sanilac for homecare

Consumers today place a high value on health and cleanliness in their lives … and in the environment. That’s why it’s important that your cleaning products deliver powerful antimicrobial properties in a form that won’t take a toll on the planet.

New consumer attitudes towards green chemistry and stringent regulatory policies are moving the household arena toward safer, healthier and more sustainable product formulations and homecare ingredients. Preservatives like benzoic and sorbic acid for homecare are widely available, but they are also synthetic and can be challenging to formulate with. But L(+) lactic acid is a safe and natural antimicrobial for homecare formulations; enabling powerful cleaning that makes a difference.

PURAC^® Sanilac is already widely acknowledged for its antibacterial benefits across a wide range of cleaning and disinfecting products in home care, industrial and institutional applications. Now its antiviral qualities have been recognized too. Easily replacing isothiazolinones, PURAC^® Sanilac is a natural in-can preservative ingredient that helps bring products to market faster, while also allowing a quick and effective response to changing regulations and trends.
