Description

Technical Field

[0001] This invention belongs to the field of body lotion preparation technology, specifically relating to a soothing and firming fragrant body lotion and its preparation method. Background Technology

[0002] Body lotion is a common cosmetic used to moisturize and care for the skin on the body. As consumers' skincare needs become increasingly sophisticated and diversified, the market expects body care products that can simultaneously meet multiple needs, such as soothing sensitive skin, firming the skin, providing long-lasting hydration, and delivering a pleasant fragrance experience.

[0003] In existing technologies, some multi-functional repair cosmetic compositions typically include an aqueous component, an oil component, and a post-addition component. For example, firming ingredients such as niacinamide are added to the aqueous component, while moisturizing oils and emulsifiers are added to the oil component. After the water and oil components are emulsified at high temperature, a post-addition component containing heat-sensitive ingredients such as fragrances and repair agents is added after cooling. However, these solutions usually only involve a simple physical mixing of active ingredients with different functions, making it difficult for the components to achieve synergistic effects, resulting in a lack of prominent overall effects such as soothing, firming, and moisturizing.

[0004] For example, the invention with application number 202010091681.2 discloses a rose-scented body lotion and its preparation process. The rose-scented body lotion contains active ingredients such as rose petals, niacinamide, Hedyotis diffusa extract, Orchid davidii extract, and guarana, which have the effect of moisturizing the skin, replenishing the skin with the required moisture and nutrients, preventing dryness and dehydration, and making the skin more rosy, fair, shiny, plump and elastic.

[0005] In addition, some products add a lot of oil in pursuit of moisturizing effects, resulting in a greasy and heavy feel on the skin and poor absorption; or due to improper control of the emulsification process, the emulsion system is unstable, and water-oil separation and precipitation are prone to occur during storage or use, affecting product quality and user experience.

[0058] The beneficial effects of this invention are as follows: (1) The soothing and firming fragrant body lotion of this invention has a synergistic effect among its various ingredients, resulting in significant efficacy. This invention scientifically combines soothing ingredients such as dipotassium glycyrrhizate and comfrey root extract with skin barrier repair ingredients such as niacinamide and ceramide, as well as various natural plant oils. The synergistic effect of each component achieves a unified effect of soothing, firming, moisturizing, and repairing, resulting in a comprehensive skin care effect superior to the simple sum of individual components. This body lotion has an excellent skin feel and is refreshing and non-greasy after application.

[0059] (2) By precisely controlling the proportion of various oils in the oil phase component and combining specific emulsification and homogenization processes, the present invention makes the body lotion with a delicate texture, easy to spread and absorb. After use, the skin feels moist and smooth, without greasiness or stickiness, which significantly improves the user experience.

[0060] (3) The body lotion of the present invention is stable in nature. The two-step homogenization process of "hot emulsification-cold addition" ensures the uniformity and stability of the emulsion system and effectively prevents problems such as water-oil separation and easy precipitation during long-term storage. At the same time, heat-sensitive or volatile components such as β-carotene, arginine and fragrance are added at low temperature during the preparation of the body lotion, which effectively ensures the activity and efficacy integrity of the above raw materials.

[0061] (4) After continuous use, the soothing and firming fragrance body lotion of the present invention will not cause any adverse reactions on the skin and body. After use, the body lotion feels moisturizing but not greasy, light and easy to spread and absorb, has a long-lasting moisturizing effect, can repair the skin barrier, can leave a fragrance for 24 hours, can improve skin redness, has a soothing effect, and can relieve dryness and itching caused by dry skin. The body lotion of the present invention is gentle and non-irritating. Attached Figure Description
