Embodiment 2

[0058] Embodiment 2 Contains the antibacterial composition of vine tea extract the purposes in the preparation of cosmetics

[0059] 1. Preparation of cream

[0060] Considering that the color of the vine tea extract will affect the perception of the actual product, the concentration of the vine tea extract was reduced to 6.25 mg (crude drug amount) / mL during the preparation of the cream. Add the compound preservative into the oil phase together. The oil phase and the water phase are respectively placed in a constant temperature water boiler and heated to 80°C. Use 7000rpm to homogenize the water phase. At the same time, mix the oil phase components evenly and slowly pour them into the water. In the phase components, after homogenizing for 3 minutes, stir and cool to room temperature, and finally form a cream shape, and adjust the pH value to 6.0. Cream formulations are shown in Table 7.

Abstract

The invention discloses a preservative composition containing vine tea extract and its application in preparing cosmetics. The preservative composition is compounded by vine tea extract and preservative PE9010. Wherein, preferably, the crude drug amount of the vine tea extract is 3.13-25mg / ml, and the concentration of the preservative PE9010 is 1v / v%. The invention conducts research on compounding of vine tea extract (VTE) and chemical preservatives, screening of antioxidants, and screening of suitable pH to determine the best application conditions. The results of the experimental formula were added to cosmetics, and antiseptic challenge experiments were carried out according to the test methods of the American Cosmetic, Toiletry and Perfume Industry Association (CTFA), providing effective technical means for the application of vine tea extracts in the field of cosmetics.

Description

technical field [0001] The invention relates to a preservative composition containing vine tea extract and its application in the preparation of cosmetics, belonging to the technical field of cosmetics. Background technique [0002] Because of its unique ingredients, cosmetics contain a lot of oil and suitable moisture and pH value, which are easy to breed bacteria. Therefore, certain preservatives must be added to cosmetics to prevent spoilage. At this stage, consumers are more advocating the concept of green and environmentally friendly consumption. At the same time, with the continuous development of technology, scientific and technological personnel have more methods for the separation and purification of plant-derived antibacterial substances. In recent years, domestic and foreign legislative bodies have continuously restricted the types and contents of chemical preservatives used in cosmetics. The number of invention patents using plant ingredients as preservatives h...
