1. An additive composition comprising:
(a) a plurality of first particles, the first particles comprising about 95 wt. % or more an impact modifier selected from the group consisting of styrene-butadiene block copolymers, styrene-ethylene/butylene-styrene block copolymers, styrene-ethylene/propylene-styrene block copolymers, and mixtures thereof; and
(b) a plurality of second particles, the second particles comprising:
(i) about 20% wt. to about 80% wt, based on the total weight of the second particles, of a polypropylene random copolymer, wherein the random copolymer is made by the polymerization of propylene and about 1 wt. % to about 7 wt. % of a comonomer selected from the group consisting of ethylene, but-1-ene, and hex-1-ene;
(ii) about 20% wt. to about 80% wt, based on the total weight of the second particles, of an acetal compound of Formula (I):

OG Complex Work Unit Chemistry
wherein R1 is selected from the group consisting of hydrogen, alkyl groups, alkenyl groups, hydroxyalkyl groups, alkoxy groups, alkyl halide groups, and derivatives thereof; R2, R3, R4, R5, R6, R7, R8, R9, R10, and R11 are each independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, alkenyl groups, aryl groups, carboxyl groups, and halogens; and R12 is a hydroxyalkyl group selected from the group consisting of —CH2OH and —CH(OH)CH2OH; and
(iii) about 4% wt. to about 80% wt, based on the total weight of the second particles, of a co-additive compound selected from the group consisting of a poly[di(ethylene glycol) adipate] having a molar mass of about 300 g/mol to about 10,000 g/mol, a branched polyethyleneimine having a molar mass of about 1,000 g/mol to about 10,000 g/mol, and mixtures thereof.
