Abstract
The invention belongs to the field of laundry detergent, and relates to a microcapsule essence laundry detergent and a preparation method thereof. The microcapsule essence laundry detergent contains sorbitan fatty acid ester, alkyl sodium sulfonate, acrylamide/2-acrylamide-2-methylpropanesulfonic acid copolymer, polysiloxane, microcapsule essence, a bactericide and deionized water; the microcapsule essence consists of a wall material and a core material, wherein the wall material is polyurea resin, and the core material is prepared from the following raw materials in percentage by weight: 1-5% of tea tree essential oil, 3-6% of eucalyptus oil, 0.5-1% of rose essential oil, 30-40% of p-tert-butylcyclohexyl acetate, 2-6% of ethyl naphthyl ether, 5-10% of tricyclodecenyl acetate, 8-12% of isopropyl myristate, 1-5% of dodecanonitrile and 1-5% of dodecanal. The microcapsule essence laundry detergent provided by the invention can delay the sedimentation of the microcapsule essence.
Description
Technical Field
The invention belongs to the field of laundry detergent, and particularly relates to a microcapsule essence laundry detergent and a preparation method thereof.
Background
The microcapsule essence is a very tiny saccular substance formed by taking a high molecular compound as a wall material and encapsulating the required essence in the wall material. The microcapsule essence is favored by consumers due to good slow release property. Microcapsule essence is added into the laundry detergent, and when the obtained microcapsule essence laundry detergent is used for washing clothes, the capsule wall of the microcapsule essence is gradually broken due to friction between clothes and between the clothes and rolling in the washing machine, so that the fragrance retaining effect is achieved.
In addition, the microcapsule essence particles in the microcapsule essence laundry detergent are initially in a suspended state, but due to the influence of gravity and interfacial energy, the microcapsule essence particles are aggregated and settled along with the prolonging of storage and gradually settle at the bottom of the laundry detergent, so that the use effect is influenced. Therefore, there is an urgent need to develop a laundry detergent that can avoid or delay the precipitation of microcapsule perfume particles.
