Problems solved by technology

At present, most of the moisturizing skin care products on the market are traditional oil-in-water creams, which are mainly a stable emulsion formed by wrapping oil particles with emulsifiers. They are not waterproof, and the moisturizing performance is not long-lasting. More oil content makes consumers feel sticky when applied, especially for consumers with oily skin or in hot summer, and the added emulsifier is one of the potential irritants of cosmetics; while commercially available oil packs Water needs to be emulsified, and the moisturizing cream produced has relatively good moisturizing durability, but most of them have bad skin feeling or poor stability

Abstract

The invention relates to a moisturizing cream and a preparation method thereof. The moisturizing cream is composed of an oil phase with a water-locking and moisturizing function, a water phase with a water-replenishing function, and a film-forming aid; the oil phase is suspended and dispersed in the water phase and the film-forming aid The oil phase includes the following components in parts by weight: shea butter: 2.0-4.0%; ethylhexyl palmitate: 2.0-4.0%; hydrogenated olive oil: 1.0-3.0% and Polydimethylsiloxane: 5.0~8.0%. The moisturizing cream prepared by using the oil suspension technology in the invention is mild and non-irritating, has smooth skin feeling, refreshing and non-sticky, and has good moisturizing performance.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a moisturizing cream and a preparation method thereof. Background technique [0002] Physiological studies have shown that 70% of the body's body weight is water, while the skin is the body's water reservoir, and its water content accounts for about 18-20% of the body's body weight. Healthy skin is smooth, moist and elastic. If the skin lacks water, it will lead to dry skin, loss of elasticity, wrinkles and premature aging; severe skin will lead to chapped skin. Factors such as air-conditioning, environmental pollution, temperature changes and pressure brought about by seasonal changes in life, as well as skin aging and metabolic slowdown will cause skin moisture loss, making skin rough, dull, dry lines, and causing many skin problems. If the face is in a dry state for one day, it will lose its original elasticity; if it lasts until the third day, it will ...
