Description

Composition for inhibiting sweating of lip balm and repairing lip injury

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a composition for inhibiting sweating of a lip balm and repairing lip injury and a preparation method thereof.

Background

Due to the reasons of environment, seasonal weather and the like, in dry and cold seasons of autumn and winter and daily life, people can suffer from troubles of dryness, cracking, peeling, pain, lackluster and the like caused by lips, so that the mood is influenced, and much inconvenience is brought to the life and work of people. In order to keep the lips away from the annoyances of dryness, cracking, peeling, pain, dullness, etc., most people who love beauty will choose some products for caring the lips: such as lip balm, lip gloss, lipstick, lip glaze, and the like.

At present, most of lip balms generally have the problem of sweating, and are not favorable for long-term stable quality, production, storage and use of products. In most documents, it is considered that the sweating of the lip balm is mainly caused by unbalanced proportion of the formula, particularly, the lip balm contains castor oil and white mineral oil, and the sweating is a seasonal phenomenon, in spring and winter, the crystal structure of the cream is relatively stable, the oil wax is in a balanced state, the sweating basically does not occur, but the wax crystal lattice changes along with the increase of the ambient temperature and humidity, the temperature fluctuation increases, the wax crystal lattice changes, the balance of the oil wax is changed, and therefore, the oil in the cream migrates from the wax crystal lattice to the surface of the cream to form the sweating phenomenon.

The main components of the common lipstick are mineral oil, wax, animal and vegetable oil, wax, synthetic oil, wax and the like. In order to achieve the effect of good moisturizing and repairing performance of the lip balm, more vegetable oil and fat, such as castor oil, coconut oil, olive oil and the like, can be added into the lip balm on the market generally, the addition amount of wax is relatively reduced, so that the cream is easy to paint, but the vegetable oil and fat are added more, the compatibility with mineral oil fat wax is not good enough, and the cream is easy to sweat.

In order to solve the problem of lipstick sweating, the proportion of wax in the formula is increased, the melting point is increased, the heat-resistant effect is good, the cream body does not sweat, the cream body is too hard to paint, and the moistening repair effect is far from reaching, under the normal condition, the hardness and the paintability are hardly improved by singly adding certain wax, the requirement of a consumer for considering the efficacy of a lip balm product cannot be met, and the formula of the existing lip balm product needs to be further perfected.
