Description

MANUFACTURING METHOD OF SOLUBILIZED PETROLATUM COSMETIC COMPOSITION}

The present invention relates to a petrolatum cosmetic composition capable of water solubility.

Petrolatum (Vaseline) cosmetics are a personal care and cosmetic raw material that has a very significant effect such as moisture evaporation blocker, skin protection agent. In addition, it is widely used all over the world as it is used for urgent treatment of minor burns and skin trauma as well as skin diseases such as eczema.

However, in the oil-in-water or water-in-oil type products, the physical properties of petrolatum are inconvenient to use and cannot be used excessively, and even if used excessively, limitations are apparent due to compatibility problems with other raw materials and stability problems. Accordingly, when petrolatum is applied to cosmetic formulations, it is inevitably used as a cream or a small lotion type formulation or balm type or ointment. Thus, there is a lack of various product lines compared to the original performance.
