Oil-free liquid medicated makeup

Abstract

A liquid make-up based on insoluble pigments suspended in an aqueous vehicle and completely oil-free. The composition includes emollients and pigment suspending ingredients.

Description

BACKGROUND OF THE INVENTION

This invention relates to cosmetic compositions, and more particularly, this invention relates to a liquid makeup having insoluble pigments suspended in an aqueous vehicle and completely oil-free.

All prior art liquid and cream makeups contain some form of oil such as mineral oil, an animal oil, a vegetable oil, or a synthetic ester such as isopropyl myristate. These oils act as an emollient to enhance dehydration of the skin and as a lubricant to impart ease of spreading. But, the presence of oil is not indicated for oily skin. Furthermore, oil may cause color-streaking or color change and, most important, it tends to clog pores and thereby interfere with normal breathing of the skin. Thus, there is a need for a makeup composition which is free of oil.

SUMMARY OF THE INVENTION

It is, therefore, a primary object of the present invention to provide a makeup composition which is oil-free.

It is a further object of the present invention to provide a makeup composition which has emollient and lubricating properties but is oil-free.

It is another object of the present invention to provide a makeup composition having no color-streaking.

Pursuant to the foregoing objects, a makeup composition is provided based on insoluble pigments suspended in an aqueous vehicle and being completely oil-free. The pigments can be any such pigments which are well-known in the art. In the preferred embodiment, the pigments are iron oxides. The aqueous vehicle contains water-soluble, non-oily, emollient and lubricating ingredients such as propylene glycol and Glucam E-20 (ethoxylated methyl glucoside). Ingredients for suspending the pigment in the medium are also included, these ingredients being Bentone LT (equal parts of hydroxyethyl cellulose and hydrous magnesium aluminum silicate) and Darvan #1 (sodium polynapthalene sulfonate).

Other ingredients such as preservatives, perfumes, and the like which are well-known in the art may be included. Furthermore, a medicated makeup is contemplated by the present invention, the composition then including well-known topical medicaments.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Example 1

The composition according to a preferred embodiment of the invention is made using the following ingredients in the proportions indicated, as percentage by weight:

The composition is made by first charging the water to a suitable container such as a stainless mixing kettle equipped with a Lightnin' mixer. With the mixer providing fairly vigorous agitation, the Bentone LT is sprinkled in and the mixing is continued until the Bentone is completely hydrated, that is, homogeneous and lump-free. The Germall, Sequestrene, Allantoin, Triethanolamine, Aerosol, and Darvan are then added.

In a separate container equipped with a Lightnin' mixer, the propylene glycol and Glucam are charged. The Cellosize and methyl paraben are then dispersed in the propylene glycol mixture. When the propylene glycol mixture is uniform, it is added to the mixture of the other ingredients already made in the first receptacle. The pigments of Phase B are then added to the mixture and dispersed well.

When the pigments are well dispersed, the mixture is put through a colloid mill such as the Eppenbach Colloid Mill set at 0.008, into a steam jacketed stainless steel kettle equipped with a Lightnin' mixer. Heating is started as the batch is passing through the colloid mill into the kettle. This heating is done to remove air suspended in the mixture.

When the batch is completely milled, it is heated to 80.degree. C. with stirring with a Lightnin' mixer equipped with a push-up blade. When 80.degree. C. is reached, heating is stopped and cooling is begun. The mixture is cooled to about 50.degree. C.

In the meantime, the camphor and menthol are dissolved in the perfume and then added to the batch which has been cooled to about 50.degree. C. The mixture is then cooled further to about 30.degree. C.

Example 2

The more preferred composition includes the following ingredients in the indicated percentages by weight:

______________________________________PHASE ADeionized water 65.48Bentone LT 0.40Germall 115 0.35Sequestrene Na2 0.10Allantoin 0.10Triethanolamine Regular 0.30Glucam E-20 3.00Propylene Glycol USP 20.00Methyl Paraben 0.15Aerosol OT (70% aq soln) 0.05Cellosize WP 4400-L 0.20Darvan #1 0.20PHASE BCosmetic Umber C33-115 9.60PHASE CPerfume B-6548 0.05Camphor 0.01Menthol 0.01 1.00.00%______________________________________

The composition was mixed in as in Example 1. The makeup was uniform in color and non-oily. It had emollient and lubricating properties and spread evenly on the surface of the skin.

Accordingly, it will be seen that the objects set forth at the outset have been achieved. The invention has been described with reference to a present preferred embodiment which is exemplary and is not to be considered as limiting.
