The application provides an environment-friendly black soldier fly oil-peptide composite system antioxidant antibacterial hand cream preparation method, and relates to the technical field of cosmetics. The hand cream preparation method specifically comprises the following steps: S1. black soldier fly oil extraction, S2. black soldier fly oil purification, S3. black soldier fly antibacterial peptide fermentation preparation, and S4. hand cream compounding. The insect oil extraction rate reaches 87.0%, the antibacterial peptide is prepared by fermentation of insect residues without raw material waste, and the application is in line with the environmental protection concept. The constructed insect oil-antibacterial peptide composite system replaces chemical additives with natural ingredients, the DPPH free radical scavenging rate is 48.5%, and the antibacterial effect on staphylococcus aureus and escherichia coli is remarkable. The product pH is close to the physiological value of the skin, has no irritation, can continuously moisturize for more than 8 hours, and is excellent in heat resistance, cold resistance and light stability, and meets the industry standard. The enzymolysis and fermentation process is mild, there is no organic solvent residue, the process is simple and controllable, is suitable for industrialized mass production, fills the technical blank of the application of the insect oil-peptide composite system in cosmetics, and has the advantages of high safety, high efficiency, low cost, no pollution, no waste, no harm to the human body, and the like.

The present application relates to a kind of novel anti-freezing anti-cracking hand cream, according to percentage by weight, including, water phase:55~65%, oil phase:28~38%, emulsification-stable system:3~6%, active repair phase:2~4%, buffer-preservation-fragrance:0.3~0.8%;Wherein, water phase includes, bamboo leaf oligosaccharide:5~10%, 1,3-propanediol:8~12%, erythritol:3~6%, purified water: remainder to water phase 100%;Oil phase includes, camellia seed oil:8~12%, mango seed fat:6~10%, coconut oil MCT:4~8%, phytosterol ester:2~4%, rice bran wax microparticle:2~4%;Emulsification-stable system includes, sucrose stearate:2~3.5%, hydrogenated lecithin:1.5~2.5%, sphingomonad fermenting polysaccharide:0.3~0.7%.The present application also relates to a kind of novel anti-freezing anti-cracking hand cream preparation process.The present application gives quantifiable systematic breakthrough to the current hand cream "thick heavy stuff, high temperature inactivation, low temperature failure, poor wash resistance, slow repair, non-environmental protection " six structural pain points: absorption is fast, extrusion force is small, wash resistance is prolonged, and fissured healing is fast.
