How to formulate better products in the current climate
Consumers are already rising to the challenges this pandemic brings, from not touching your face (which is harder than it sounds) to thorough, regular handwashing. Whether you’re scrubbing along with Gloria Gaynor or practicing your technique with “Bohemian Rhapsody”, you’ve likely heard the importance of washing your hands for at least 20 seconds.
As we all know, excessive hand washing weakens the lipid barrier of the skin, and who needs dry hands right now? Moisturizing ingredients are essential in hand soap formulations. Lamesoft® PO 65 uses a nature-based lipid that also occurs naturally in human skin to create an intensive moisturizing, skin-softening sensation. Check it out in this Moisturizing Liquid Hand Soap formulation.
Some surfactants found in soap can also be harsh on the skin. Plant-based surfactants, such as Plantaren® 818 UP and Plantaren® 1200 N UP, are mild and gentle on the skin and made with natural, sustainable ingredients. These non-ionic surfactants also work well with benzalkonium chloride for gentle sulfate-alternative antibacterial hand soaps.
Hand sanitizers are another sticky formulation challenge. It can be tough to get the right consistency in a high-alcohol formula, especially with carbomers currently in short supply. If you’ve read this far, you probably know that hand sanitizers are recognized by the FDA as OTC drugs, so there are some requirements manufacturers have to meet before starting production.
If your company is adding emergency capacity to make hand sanitizer, please check the FDA guidance before you start working on a new formula. BASF regulatory experts are here to help you decipher the new rules and regulations, so reach out to us!
If your company is already making hand sanitizers, you’re good to go! The following tips are for you.
If you need alternatives to carbomers, we have options. Cosmedia® Triple C, an EO-free cationic liquid dispersion polymer, thickens high alcohol formulations at as little as 2% (and offers a great sensory profile). Check out these two formulations that use it: Silky Hand Sanitizer and Safe and Soft Hygiene Hand Gel.
Alternatively, Cosmedia® Ultragel 300 is a do-it-all polymer that thickens and stabilizes formulations at very low concentrations, even 1% in recent tests.
If your formula’s main active ingredient is isopropanol or ethyl alcohol, Rheocare® TTA and Luviset® 360 are two dispersions of acrylic copolymer in water that excel at building viscosity in a high-alcohol solution. Rheocare® TTA is unpreserved and is ideal for transparent gels. It has a low pH, so look to add a neutralizer. Luviset 360 produces a crystal-clear finish, great gel texture, and works around pH 3-6. Check out Rheocare TTA in this Bactericide Hand Cleanser formula and Luviset 360 in this Crystal Clear Sanitizing Gel formula.
With everyone cleaning knobs and handles once per day, convenience is at a top priority. Emulgade® CM , a liquid emulsion concentrate, has everything you need for an effective skin conditioning wipe. Wet wipe Basic Formula will get you started on your way. Emulgade® CM can also tolerate isopropyl alcohol, so be sure to check out the Hygiene Wet Wipe formulation as well.
