Embodiment 1A

[0392] Example 1A - Lip Protectant Composition

[0393] A lip protectant composition with the following formulation was prepared, Table 3:

[0394]

[0395]

[0396] The composition is prepared in two important steps. In a first step, a concentrate having a lamellar film structure* composition (see Table 4) was prepared. The concentrate contains hydrogenated lecithin, palmitamide MEA, rice bran oil, rice bran wax, shea butter cream, squalane, pentylene glycol, glycerin, phytosphingosine, ceramide 3 and water. In a second step, the concentrate is added during the formulation of an oil-in-water emulsion to obtain the final composition shown below:

[0397] (a) Phase 1 (aqueous):

[0398] 11.955% by weight water

[0399] 0.200% by weight octane glycol

[0400] 12.000% by weight glucose monohydrate

[0401] 0.200% by weight dehydroxanthan gum

[0402] 20.670% by weight glycerin

[0403] 0.185 wt% NaOH

[0404] 1.000% by weight capryl glycine

Abstract

The invention provides for a topical o / w emulsion having moisturizing, and protecting, repairing or restoring the skin lipid barrier of the lips of a mammal, and is a topical oil-in- water emulsion composition comprising: (a) a discontinuous oil phase; (b) a continuous aqueous phase comprising water and glycerin, wherein glycerin is present in an amount greater than about 12% w / w; (c) a thickening agent; and (d) at least one lamellar membrane structure; and wherein the composition is a lip protectant composition.

Description

technical field [0001] The present invention relates to novel moisturizing and barrier repairing and / or restorative lip protector compositions comprising high levels of glycerin. Background technique [0002] Unprotected skin is prone to dehydration and becomes irritated by exposure to the elements. This is especially true of the lips, which have been found to lose water more than usual skin. In this regard, the lips have a thinner stratum corneum and also contain lower amounts of lipids than other parts of the body. When the lipid barrier is depleted or insufficient, lips dry out, become irritated and prone to cracking. The lips also contain less melanin than other areas of the skin, so there is a risk of sunburn and UV damage. Therefore, there is a great need for effective lip protectant compositions. [0003] There are many products on the market that are used to keep lips moisturized and smooth, and to protect them from damage. These products often contain waxes and...
