Coolness delivery composition for absorptive product and preparation method thereof

Abstract

The invention provides a coolness delivery composition for an absorptive product. A freshener is added into sanitary towels, panty-shape diapers or protection pads in the form of microcapsules or powder, and menthyl acetate with mild and durable cooling performance is taken as a raw material, so that the problems of easiness in volatilizing of a liquid freshener, low utilization ratio of effective substances, short product shelf life and easiness in stimulating skin of the freshener are solved. Due to the adoption of the technical scheme, a formula is simple, and a preparation process is simple and convenient. The utilization ratio of a microcapsule or powder freshener effective substance is high, the product shelf life is long, and the cooling feel is mild and durable.

Description

technical field [0001] The invention belongs to the field of disposable hygiene products, and in particular relates to a cooling sensation delivery composition and a preparation method thereof. Background technique [0002] Although various characteristics of absorbent articles, such as protection and comfort in use, have been greatly improved in recent years, consumers still expect further improvements in such products, even when wearing absorbent articles such as feminine absorbent articles. The experience is more pleasant, especially after wearing the product for a long time. [0003] In the field of absorbent articles, cooling agents stimulate the body's cold receptors to deliver a cooling / refreshing sensation without changing the body surface temperature of the article wearer. It can effectively relieve the feeling of stuffiness during wearing the product. In the existing technical solutions, the cooling agent is mostly in liquid form, and the cooling agent is loaded ...

AI Technical Summary

Problems solved by technology

[0004] The existing technology mostly adopts spraying or impregnating the cooling agent solution, and the cooling agent migrates in each layer of the sanitary napkin, resulting in the loss of the cooling agent, and the cooling feeling is not stable enough

Moreover, as consumers further improve the comfort requirements of absorbent products, in order to improve the air permeability and absorbency of absorbent products, the surface layer and the core layer are arranged with air holes and permeation holes, which further aggravates the load of the cooling agent on the surface of the absorbent product. Migration during the product process, resulting in unstable performance

[0005] On the other hand, with the improvement of the air permeability of absorbent products, it also brings greater challenges to the storage stability of absorbent products loaded with coolant solutions. In order to enhance the storage stability of products, in the prior art solutions Absorbent products are mostly packaged with aluminum-plastic composite film, which increases the cost of the product

Or enhance the storage stability of the product by applying cooling agents that are more stable to heat and more expensive, such as menthyl esters, menthyl amide, etc., because the stability of this type of cooling agent is enhanced, it needs to be stably arranged in a position close to the surface layer, but due to The application in the form of liquid spraying cannot avoid the migration of the cooling agent on the absorbent product. In order to obtain a stable cool feeling, it is necessary to increase the amount of addition, which not only increases the manufacturing cost, but also easily causes irritation due to a large amount of cooling agent directly contacting the skin of women's private parts, causing Burning, stinging and other phenomena, which increase the safety risk of product application
