The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, fabric care products, such as fabric softeners, laundry detergents, rinse added products, and other fabric care products, to enhance fragrance performance. The controlled delivery system of the present invention is a solid, substantially spherical particle comprising hydrophobic cationic charge enhancing agents in conjunction with cationic fabric softening agents that assist in adhering the particles onto fabric. The particles can also include a fragrance. The particle can have an average particle diameter of from about 1 micron to about 500 microns. The controlled delivery system of the present invention can be utilized to deliver a broad range of fragrance ingredients onto fabric and prolong fragrance release from the dry laundered fabric over an extended period of time, or yield a high impact fragrance “burst” upon ironing the fabric. The invention also pertains to fabric care products comprising the controlled release system of the present invention.
本发明涉及一种受控递送系统,该系统可掺入液体、干粒状或粉末状织物护理产品(如织物柔软剂、洗衣粉、漂洗添加产品和其他织物护理产品)中,以增强香味性能。本发明的控释系统是一种固态的球形颗粒,由疏水性阳离子电荷增强剂和阳离子织物软化剂组成,有助于将颗粒粘附在织物上。颗粒还可以包括香料。颗粒的平均直径可从约 1 微米到约 500 微米不等。本发明的受控递送系统可用于将多种香味成分递送到织物上,延长干洗织物的香味释放时间,或在熨烫织物时产生高冲击力的香味 "爆发"。本发明还涉及包含本发明控释系统的织物护理产品。
