Preservative compositions containing emollient solvents such as octanediol or Symdiol.TM. or octoxyglycerine monoesters in combination with organic acids such as alpha hydroxyl acids can be used for preventing microbial growth and spoilage in cosmetic and topical skin formulations with the added benefit of providing silky smooth texture to skin. The compositions may optionally contain an essential oil/component. These preservative compositions are odorless and colorless and small concentrations can be added to cosmetic/topical formulations to prevent bacterial, yeast and fungal growth within 24 to 48 hours after contamination.
