Homeo-Shield 1 L

Keeping Water-Based Formulas Stable at Industrial Scale

When a formula moves from small test batches to full production runs, protecting the finished product against bacteria, mold and yeast growth becomes a decisive factor for shelf life and profitability. Homeo-Shield, 1 L is a broad-spectrum preservative built for exactly this stage, listed under Preservatives and Antioxidants and used across creams, lotions, emulsions, gels and shampoos where water content creates a favorable environment for microbial growth. The one-liter packaging is aimed at studio and industrial manufacturers who need predictable, batch-to-batch performance over months of continuous supply rather than a single trial run.

The strongest demand for this type of preservative comes from the cosmetics industry — facial and body creams, hair care products, water-based makeup, and rinse-off formulations. Beyond skin and hair care, similar preservation systems are widely used in household chemicals manufacturing: liquid dish soap, fabric softeners, multi-purpose cleaning gels, and laundry products where the aqueous phase dominates the recipe and requires reliable protection. It also finds application in wet wipes production and antimicrobial textile treatments. Soap making occupies a minor place in this list, since solid bar soap is naturally resistant to microbial growth due to its alkalinity, while liquid soap formulations do require full preservation.

Homeo-Shield is best added at the final cooling stage of production, once the batch has dropped to room temperature or slightly above — generally not exceeding 40 degrees Celsius, to avoid degrading the active compounds. Typical usage rates range from 0.5 to 1.5 percent of the total formula weight, depending on the pH of the base and the intended shelf life of the finished product. It pairs well with other protection systems: for naturally positioned formulas it is often combined with Leucidal Liquid 10 ml, while for broader spectrum coverage and stability across a wider pH range manufacturers add Sepicide HB 10 ml.

When a formula contains vegetable oils prone to oxidation, technologists often introduce an antioxidant such as Neodefend 10 g to prevent rancidity of the oil phase and extend the product's usable life. Store Homeo-Shield in a tightly sealed container, in a cool dry place away from direct sunlight and temperature fluctuations. Under proper storage conditions the preservative retains its stated activity for the full shelf life, which matters greatly when building inventory for a continuous production line.
