An aqueous multilamellar composition for delivering hydrophobic substances

Abstract

The invention discloses an aqueous multilamellar composition for delivering a hydrophobic substance. The composition herein comprises: (i) about 50 wt. % to about 80 wt. % of phenylethylalcohol and / orphenylpropylalcohol; (ii) a mixture of (a) about 10 wt. % to about 20 wt. % of polyglyceryl-4 laurate / sebacate and (b) about 10 wt. % to about 20 wt. % of poly glyceryl- 6 caprylate / caprate; (iii) about 10 wt. % to about 20 wt. % of octane- 1,2-diol; (iv) optionally about 10 wt. % to about 20 wt. % of 1,3- propanediol; and (v) about 5.0 wt. % to about 80 wt. % of water. Also described is a methodof use and process for preparing the same.

Description

field of invention [0001] The present application relates to multilayer compositions, and more particularly, to aqueous multilayer compositions for the delivery of hydrophobic substances such as phenylethyl alcohol and / or phenylpropanol. Background of the invention [0002] Phenylethyl alcohol and phenylpropanol are typical fragrance components in personal care, household, industrial and pharmaceutical products, etc. These substances have a preservative and / or antimicrobial synergistic effect. However, the use of phenylethyl alcohol and phenylpropanol substances limits the formulator due to, for example, their poor solubility in water, loss of activity upon evaporation and distribution into packaging materials, and strong odor due to their high vapor pressure. [0003] In view of the above, there is still a need to find ways to increase solubility, prevent loss of activity and reduce the vapor pressure of phenylethyl alcohol and phenylpropanol. [0004] Therefore, the main...
