The instant invention provides for novel cationic lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with oligonucleotides. It is an object of the instant invention to provide a catiomc lipid scaffold that is susceptible to hydrolytic instability that may translate into reduced liver residence times and reduced hepatocellular toxicity. The present invention employs acetals and ketals to provide a low pH sensitive chemical handle for degradation.
