Problems solved by technology

However, when it is used alone as an emulsifier, its emulsifying ability is low, and the liquid crystal structure produced is greatly affected by the formula, and there are many factors affecting the formation of liquid crystals
Therefore, there are a series of problems such as low probability of lamellar liquid crystal formation, incomplete shape, and small quantity in the preparation of products by randomly selecting raw materials, which has great restrictions on material selection.
At present, many products using glucoside liquid crystal emulsifiers on the market are rarely observed to have a relatively good liquid crystal structure

Embodiment 1-3

[0044] Moisturizing creams A-C with good liquid crystal structure of Examples 1-3 were formulated according to Table 1.

[0045] Table 1 Moisturizing creams A-C with good liquid crystal structure

[0046]

[0047]

[0048] The preparation method of the above-mentioned moisturizing cream A-C with good liquid crystal structure comprises the following steps:

[0049] S1: Take water, humectant and water-soluble polymer thickener, mix them, raise the temperature to 80°C, keep warm and stir for 20 minutes, and prepare the water phase;

[0050] S2: Take alkyl glucoside, higher fatty alcohol, polyglycerol ester and emollient oil, mix them, heat up to 80°C, keep warm and stir for 15 minutes until completely dissolved, and obtain an oil phase;

[0051] S3: Add the oil phase to the water phase, homogenize for 10 minutes at a rotational speed of 3000r / min, cool down to 45°C, add auxiliary materials, stir for 30 minutes, send for inspection, and discharge after passing the test.

Abstract

The invention provides a moisturizing cream with good liquid crystal structures. The moisturizing cream mainly includes the following components of, by weight, 0.5-5% of alkyl glucosides, 1-8% of higher aliphatic alcohol, 0.5-3% of polyglycerol ester, 10-40% of grease, 0.1-5% of high polymer thickeners, 0.1-10% of moisturizing agents and the balance water. According to the moisturizing cream withthe good liquid crystal structures, the alkyl glucosides, the polyglycerol ester and the higher aliphatic alcohol are reasonably matched, and interface stacking parameters are adjusted so that the multiple layered liquid crystal structures which are uniform, bright and complete can be formed, and the formed liquid crystal structures are stable. The moisturizing cream has an excellent moisturizingfunction, can decrease the percutaneous moisture loss rate obviously and has the excellent effect on maintaining skin moisture.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a moisturizing cream with a good liquid crystal structure and a preparation method thereof. Background technique [0002] Liquid crystal skin care products are new skin care products that have attracted much attention in recent years. Because the lamellar liquid crystal has an oil / liquid crystal / water structure, which is very similar to the structure of the human skin barrier, when it exists stably in an oil-in-water skin care emulsion, it can provide efficient moisturizing and slow-release active ingredients for the emulsion, thereby It can help professional functional products and cosmeceutical skin care products play a greater role in skin care and beauty. [0003] There are six main types of liquid crystal emulsifiers, namely phospholipids, glucosides, sucrose esters, phosphate esters, olive esters and stearyls. As one of the liquid crystal emulsifiers, glucoside emulsi...
