Product Overview
What Is LGP?
LGP is a broad-spectrum powder preservative developed for water-containing personal care formulations.
Two Complementary Preservative Ingredients
LGP contains DMDM Hydantoin and Iodopropynyl Butylcarbamate. DMDM Hydantoin is commonly used to support bacterial control, while IPBC is particularly effective against yeast and mold.
By combining the two ingredients, LGP provides broader antimicrobial coverage than either ingredient may provide alone.

Preservation Function
How LGP Supports Product Preservation
Microbial contamination can affect product appearance, odor, viscosity, stability and safety. LGP combines two complementary preservation functions.
Bacterial Control Support
DMDM Hydantoin is commonly used to support control of Gram-positive and Gram-negative bacteria in water-containing formulations.
Yeast and Mold Control Support
IPBC provides strong activity against yeast, mold and fungal contamination that may contribute to product spoilage.
Complementary Broad-Spectrum Protection
The two ingredients cover different microbial groups, making LGP relevant to broad-spectrum preservation strategies at a relatively low use level.

Market Applications
Typical Applications of LGP
Shampoo and Conditioner
LGP is commonly used in shampoo and conditioner formulations to help protect water-based hair care products from microbial contamination.
Its low recommended use level makes it particularly suitable for high-volume hair care production where manufacturers need to balance preservation performance and formulation cost.
Body Wash and Shower Gel
Body wash and shower gel are among the most relevant applications for LGP.
These products contain high levels of water and are produced in large volumes, so an efficient, broad-spectrum and cost-effective preservative system can provide clear commercial value.
Hand Wash and Liquid Soap
LGP can be used in hand wash and liquid soap formulations to support protection against bacteria, yeast and mold during storage and consumer use.
It is well suited to everyday cleansing products that require reliable preservation and competitive raw material costs.
Facial Cleanser
LGP may be used in rinse-off facial cleansers, including gel, foam and cream cleanser formats.
For manufacturers producing mass-market or cost-sensitive cleansing products, LGP provides a practical preservative option with a familiar DMDM Hydantoin/IPBC system.
Wet Wipes
LGP may also be used in selected wet-wipe formulations to help protect the water-based liquid from microbial contamination.
Wet wipes require careful preservation because the formula remains in continuous contact with the wipe material and packaging. Final suitability should therefore be confirmed in the complete packaged product.
Selected Lotions and Creams
LGP may be considered for selected lotions, creams and other leave-on formulations.
However, leave-on applications require closer review of the product category, target market, intended dosage and applicable regulations. Noyain recommends completing regulatory assessment and preservative efficacy testing before commercial use.
