The invention belongs to the field of organic silicon, and particularly provides self-emulsifying cationic silicone wax as well as a preparation method and application thereof. The self-emulsifying cationic silicone wax is represented by the following average composition formula (I): R < 1 > aR < 2 > bR < 3 > cSiO < 4-a-b-c > / 2 (I), in the formula, R1 is represented by a general formula (II), and R2 is represented by a general formula (III); r3 is an organic group; * represents a connection position; a ranges from 0.01 to 0.5, b ranges from 0.05 to 0.5, and c ranges from 1.4 to 2.5. The preparation method of the self-emulsifying cationic silicone wax comprises the following steps. The self-emulsifying cationic silicone wax provided by the invention is soft hydrophobic silicone wax, not only can provide excellent waterproofness and soft hand feeling, but also can improve the durability of the effect, and can be widely applied to the fields of daily chemicals, textiles, coatings and the like.

The application discloses a high-stability peach gum polysaccharide nanoemulsion loaded with hydrophobic functional molecules and a preparation method thereof, and relates to the field of natural polymer materials and nanotechnology. The peach gum polysaccharide is chemically modified by thioctic acid, the balance of hydrophilicity and hydrophobicity in the molecular structure is effectively regulated, and thus the peach gum polysaccharide is endowed with excellent self-emulsifying capacity. A plurality of hydrophobic functional components can be efficiently loaded without additional addition of synthetic emulsifiers, the obtained nanoemulsion system is uniform and stable, and has good biocompatibility and slow-release performance. The emulsification and active component loading process are integrated in one step, the process flow is simplified, the loss of active components in multi-step operation is effectively avoided, the preparation efficiency and practicability are significantly improved, and a new way is provided for efficient and safe delivery of natural functional components.
