Myristamidopropyl Dimethylamine (MAPD) is a multifunctional fatty amidoamine compound combining superior surface activity with high biocompatibility. In the ophthalmic pharmaceutical and vision care industries, it serves as a gentle yet potent antibacterial preservative for eye drops, artificial tears, and multi-purpose contact lens care solutions, including RGP and orthokeratology lens regimens, effectively inhibiting bacteria, fungi, and Acanthamoeba without causing corneal epithelial toxicity associated with conventional preservatives. In personal care and cosmetics, once protonated in mildly acidic formulations, it functions as an exceptional cationic conditioning agent, antistatic agent, and detangler in hair conditioners, hair masks, and shampoos, imparting silkiness, wet-combability, and frizz control. Furthermore, it acts as a vital chemical intermediate for synthesizing amine oxides, amphoteric betaines, and quaternary ammonium surfactants used in household fabric softeners and specialized industrial cleaning formulations.

Antibacterial preservative

For monthly or annual contact lenses, the proteins, enzymes and oils in the tear film accumulate on the lenses over time. Excessive accumulation will damage the quality of the tear film between the lens and the cornea, causing dry eyes, congestion and discomfort. Therefore, we need to remove foreign matter from the lenses regularly. The role of the care solution is to sterilize and dissolve the proteins on the lenses. Polyquaternium-1 (Polyquad-1; PQ-1; CAS# 75345-27-6) and Myristamidopropyl Dimethylamine(CAS# 75345-27-6) are used in the care solution as new and milder bactericides.
