A packaging composition comprising a hydrophilic lipid composition and a water-based liquid that respectively are packaged individually and combined together. The hydrophilic lipid composition contains liquid fat and an emulsifier. The content of the liquid fat in the hydrophilic lipid composition in terms of weight is greater than 45%. The content of the emulsifier in the hydrophilic lipid composition in terms of weight is 0.05% to 8%. The weight ratio of the water-based liquid to the hydrophilic lipid composition is greater than 3:1. The sum of the volume of the water-based liquid and the hydrophilic lipid composition is no greater than 98% of the volume of a container holding the water-based liquid. A method for blending the hydrophilic liquid composition and the water-based liquid into an emulsion, comprising: pouring the hydrophilic lipid composition and the water-based liquid into a blending bottle, and shaking the blending bottle for at least once in one second either by hand or by a manipulator. Applications of the method for blending the hydrophilic lipid composition and the water-based liquid into the emulsion in preparing or blending a medicament, a special medical use formula food product, a healthcare food product, a nutritious food product or a cosmetic product.Linvention concerne une composition demballage qui comporte une composition lipidique hydrophile et un liquide à base deau qui sont respectivement emballés individuellement et combinés ensemble.
