Abstract
The present invention relates to a plasticizer composition including a lower alkyl-based citrate and a higher alkyl-based citrate simultaneously as citrates, wherein effects are achieved through controlling the ratio of hybrid and nonhybrid types, and the ratio of lower alkyl and higher alkyl, and if the plasticizer composition is applied in a resin, stress resistance and mechanical properties may be maintained to the equal or better levels, balance between migration and loss properties, and plasticization efficiency may be achieved, and light resistance and heat resistance may be markedly improved.
Claims10
A plasticizer composition comprising a citrate-based composition comprising three or more citrates of the following Formula 1, wherein:
- in Formula 1, R1 to R3 are each independently an alkyl group of 4 or 6 carbon atoms, and R4 is an acetyl group,
- the alkyl group is derived from a C4 alcohol or a C6 alcohol,
- the C4 alcohol comprises one or more selected from the group consisting of n-butanol and isobutanol,
- the C6 alcohol comprises 1-hexanol, 2-methylpentanol, and 3-methylpentanol, and
- a weight ratio of the C4 alcohol and the C6 alcohol is from 5:95 to 95:5.
