AI Technical Summary

Technical Problem

Existing moisturizing creams suffer from poor moisturizing effect, an imbalance between skin feel and moisturizing effect, poor ingredient compatibility and stability, and limited efficacy of conventional surfactants, making it difficult to meet the multi-dimensional performance requirements of high-end moisturizing creams.

Method used

Using a novel EO-type nonionic oil surfactant as the core active ingredient, a stable synergistic system is formed by precisely optimizing its compatibility and preparation process with other components of the face cream. This system includes an EO-type nonionic oil surfactant prepared by adding plant fruit oil and ethylene oxide, combined with castor oil, mango kernel fat, cetearyl alcohol, and other components to construct a triple moisturizing network.

Benefits of technology

It achieves multiple effects such as long-lasting moisturizing, refreshing skin feel, excellent stability and gentleness without irritation, and improves skin moisture retention by more than 70%. The product has good stability under different temperature and humidity environments.

Abstract

The application discloses a novel EO type nonionic surfactant, long-acting moisturizing cream and a preparation method thereof, and belongs to the technical field of skin care products, and aims to solve the technical problems of short moisturizing duration, sticky skin feeling, poor component compatibility and insufficient mildness of the existing moisturizing cream. The formula of the moisturizing cream product provided by the application is prepared by adding natural triglyceride and ethylene oxide (EO), the EO addition number is 5-20, and the addition amount is 4.5%-5.0% according to the mass percentage. The application realizes the long-acting moisturizing and water-locking, refreshing skin feeling, excellent stability and mildness and non-irritation of the cream by differentiating the selection and ratio optimization of the surfactant, the 24h skin water content maintenance rate is greater than or equal to 75%, and no stratification appears after 30min of high-speed centrifugation. The moisturizing cream series product is suitable for various skin types and has no irritation, the preparation process is simple and controllable, and is suitable for industrial production.
