Embodiment 1
[0066] Embodiment 1 provides the composition A1\B1\B2\B3\B4 of stabilizing retinol
[0067] Compositions A1\B1\B2\B3\B4 for stabilizing retinol correspond to Example 1 and Comparative Examples 1 to 3 respectively, and their respective components are shown in Table 1 below (the contents in the table are all in mass percentage), prepared The steps are: heat the lipid solution (i.e. (a) to (d)) in a homogenizer at 40°C and mix evenly, and then slowly add it to the water-based component containing active particles at 40°C, stir and mix evenly.

[0071] Stability Evaluation
[0072] 1. Appearance evaluation: Place the prepared stable retinol composition A1\B1\B2\B3\B4 in front of a white background board, and visually observe whether the composition is in the form of an emulsion. If there is obvious layering or particle aggregation It is X, if it is creamy, it is marked as △, if it is emulsion, it is marked as O.
