DESCRIPTION
PREFERENZ P 300 is a bacterial proteolytic enzyme preparation designed for incorporation into liquid laundry detergents.
PREFERENZ P 300 is supplied as a liquid concentrate rather than as one purified low-molecular-weight chemical substance.
PREFERENZ P 300 catalyzes the hydrolysis of peptide bonds within susceptible protein soils.
PREFERENZ P 300 converts large insoluble proteins into smaller peptides and amino acids that can disperse more readily into the wash liquor.
PREFERENZ P 300 belongs to the class of microbial detergent proteases produced through controlled fermentation.
PREFERENZ P 300 is described in patent literature as a thermostable and alkaline serine protease intended for demanding cleaning environments.
PREFERENZ P 300 is manufactured using microorganisms whose enzyme-producing capability has been improved through modern biotechnology.
PREFERENZ P 300 does not contain the production microorganisms in the finished commercial preparation according to the available technical data sheet.
PREFERENZ P 300 contains a proprietary enzyme protein with an amino-acid sequence and three-dimensional structure selected for detergent stability.
PREFERENZ P 300 does not have a publicly defined single molecular formula or one fixed molecular weight applicable to the complete formulated preparation.
PREFERENZ P 300 appears as a clear brown liquid under the typical characteristics listed in the technical data sheet.
PREFERENZ P 300 has a specified product-form pH range of approximately 5.5–6.5 and a target specific gravity of approximately 1.1.
PREFERENZ P 300 provides a minimum declared activity of 6,000 DSLU per gram under the supplier assay system.
PREFERENZ P 300 activity is expressed in functional enzyme units rather than solely through weight percentage because catalytic performance depends on active protein quality.
PREFERENZ P 300 contains enzyme concentrate, stabilizers, and preservatives in the commercial liquid formulation.
PREFERENZ P 300 may include additional formulation components required to maintain physical, microbiological, and enzymatic stability during storage.
PREFERENZ P 300 performs across representative washing conditions from approximately 20°C to 50°C and pH 6–10.
PREFERENZ P 300 may show different relative activity at each temperature and pH because enzyme conformation and catalytic rate respond to the surrounding environment.
PREFERENZ P 300 is structurally engineered to retain proteolytic activity after storage in liquid detergent matrices.
PREFERENZ P 300 therefore provides more consistent aged cleaning performance than proteases that rapidly lose activity during detergent storage.
PREFERENZ P 300 remains sensitive to excessive heat, extreme pH, aggressive surfactants, oxidizing agents, unsuitable solvents, and microbial contamination.
PREFERENZ P 300 must consequently be tested in the complete detergent formulation rather than assessed only in diluted laboratory buffer.
PREFERENZ P 300 can hydrolyze other proteins in addition to the proteins present in stains.
PREFERENZ P 300 may therefore undergo autolysis or reduce the activity of other detergent enzymes when formulation compatibility is inadequate.
PREFERENZ P 300 benefits from detergent systems containing suitable enzyme-stabilizing ingredients.
PREFERENZ P 300 may gain improved stability from sodium formate, trimethylglycine, glycerol, monopropylene glycol, calcium, borate systems, or reduced water activity when these approaches are compatible with the target formulation.
PREFERENZ P 300 generally benefits from nonionic surfactant systems that are less disruptive to enzyme structure than certain aggressive anionic environments.
PREFERENZ P 300 should not be assumed universally compatible with every nonionic surfactant because hydrophilic-lipophilic balance, solvent content, concentration, and temperature remain important.
PREFERENZ P 300 may lose stability in formulations containing high levels of hydrophobic solvents. PREFERENZ P 300 should also be evaluated carefully with formaldehyde-releasing antimicrobial systems because the technical data sheet recommends avoiding these ingredients.
PREFERENZ P 300 is normally added after high-temperature manufacturing stages to reduce thermal deactivation.
PREFERENZ P 300 should be distributed through gentle controlled mixing that avoids unnecessary foaming, aerosol formation, and prolonged high shear.
PREFERENZ P 300 is dosed according to active enzyme requirement rather than through one universal weight percentage.
PREFERENZ P 300 dosage must account for enzyme activity, detergent dose, wash-liquor volume, stain challenge, storage loss, and targeted cleaning performance.
PREFERENZ P 300 is supplied in commercial packaging formats including pails, drums, totes, and bulk delivery according to the technical data sheet.
PREFERENZ P 300 packaging should remain tightly closed to protect enzyme activity and prevent contamination during storage and use.
PREFERENZ P 300 is a protein-based catalyst and does not become a permanent structural component of washed fabric.
PREFERENZ P 300 performs catalytic hydrolysis during washing and is subsequently diluted, rinsed, degraded, or removed with the wash liquor.
PREFERENZ P 300 supports detergent sustainability strategies because enzymes can replace part of the cleaning work otherwise supplied by higher temperature or harsher chemical conditions.
PREFERENZ P 300 does not independently establish a finished detergent as sustainable, biodegradable, eco-labeled, or environmentally preferable.
PREFERENZ P 300 received historical CleanGredients approval for use in formulations targeting EPA Safer Choice recognition and United States eco-labeling.
PREFERENZ P 300 regulatory status, certification, availability, and approved claims should be reconfirmed with the current supplier before commercial use.
PREFERENZ P 300 was designed to provide detergent formulators with improved stability and greater freedom in selecting a stabilization strategy.
PREFERENZ P 300 can reduce the stabilizer requirement in some formulations, although PREFERENZ P 300 does not eliminate the need for stability testing in every detergent matrix.
PREFERENZ P 300 should be evaluated through accelerated and real-time storage studies before a commercial detergent is finalized.
PREFERENZ P 300 evaluation should measure residual enzyme activity, stain-removal performance, physical stability, odor, color, viscosity, and compatibility with other detergent ingredients.
PREFERENZ P 300 can cause occupational respiratory sensitization if enzyme-containing aerosols or airborne droplets are inhaled repeatedly.
PREFERENZ P 300 requires exposure controls designed specifically for industrial enzyme handling, including containment, ventilation, hygiene, training, and appropriate personal protective equipment.
PREFERENZ P 300 should be stored, transported, formulated, and handled according to the current concentration-specific Safety Data Sheet.
PREFERENZ P 300 specifications in older technical literature should be verified against current supplier documentation because commercial availability, formulation, certification, or product positioning may change.
The physical specifications, composition, wash window, dosage recommendations, certification statements, and manufacturing information are reported in the technical data sheet.
The stability mechanism and current safe-handling context are supported.
