Abstract

ABSTRACT

A skin moisturizing composition comprises from 10%
to 30% glycerin, in combination with from 0.2% to 5% of a polymer or copolymer which reduces the lubricity of the glycerin but does not leave a wet or oily feeling on the skin of the user.

Description

COMPOSITIONS

The present lnventlon relates to cosmetlc compositions, containlng glycerln, whlch are useful Eor mparting molsture to the skin o humans.

Hitherto~ glycerin has been suggested for use ln the treatment of dry skin conditlons but one disadvantage of any composition which contains a high concentration of glycerin lS that lt leaves a wet and coated Eeellng on the skin which is cosmetically unacceptable to ~he user.

It has now been found that the above dlsadvantage can be overcome or reduced by including polymer partlcles ln a cosmetlc composltlon containlng high levels of glycerln. At the same tlme, the skin moisturlslng properties of glycerln can be efflclently utillsed.

Accordlng to the present lnventlon, there lS
provlded a cosmetic composition for molsturislng skln, comprislng from 10% to 30%, by weight of the composition, of glycerln~ from 0.2% to 5~, by weight of the composltlon, of particulate polymer or copolymer, and a cosmetically acceptable carrier.

36'~

Preferably, the amount of glycer1n lS from 15% to 30~. Other suitable amounts of glycerln are from 10%
to ?0%, or 20% to 30%. The preferred amount of polymer or copolymer lS from 0.2% to 2%, particularly preferably about 0.5%.

The polymer or copolymer ln the composltlon of the 1nventlon should be capable of reducing the lubrlc1~y of the glycer1n so that the compos1t1on has a non-o1ly, non-wet feel on the users sk1n.

Polymers whlch are part1cularly useful in the compos1t1on according to the 1nventlon are acryl1c copolymers such as those descrlbed 1n Unlted States Patent Nos. 4,043,952 and 4,090,013, and starch-graft copolymers such as those described in US Patent Nos.
3,935,099, 3,981,100, 3,985,616, ~,069,177, 4,04S,387, 4,116,899, 4,134,863 and 4,194,998.

The composltlon of t.he lnvent.ion preferably contalns from about 0.5% to about 1~ of acryl1c or starch-graft copolymer, particularly preferably about 0.5%.

Other useful polymers are polyethylene mlcrospheres, such as Polymlst B-6 (Polymist is a trade mark), and polyamlde powder, such as Orgasol 2002D
(Orgasol lS a trade mark).

The polymer or copolymer lS preferably ln the form of part1cles having an average part1cle s1ze ln the range of 5 to 15 mlcrons, preferably 5 to 7 m1crons.

In a further aspect, the present lnventlon prov1des a method of lmparting molsture to skln wh1ch compr1ses applying to skin an effective amount of a composition of the lnventlon.

.

The compos1t1on of the lnventlon may lnclude any of the lngred1ents customarlly used in cosmetlc formulatlons lntended for appllcat1on to sk1n. Typ1cal lngredlents are preservatlves, perfumes, colouring agents and antl oxidants. The cosmetically acceptable carrler may compr1se conventional materlals such as oil-ln-water or, water-in-oll emulslons.

The compos1tlon of the lnvention may be prepared by admlxture. Accordlngly, the inventlon also provldes a process for preparlng the cosmetlc compos1tlon of the lnventlon, whlch comprlses admixlng the components of the compos1tion 1n the requlred proportlons~

The admixing should be carrled out so that the polymer or copolymer is un1formly dispersed throughout the f1nal compos1tlon.

The oll-1n-water or water-ln-oll emulsion may be prepared accordlng to general methods descr1bed in UK
Patent Speciflcation Nos. 1 489 133 and 2 026 319. The emuls1on may then be mixed wlth the glycerine and copolymer or polymer to produce the flnal composltlon of the lnventlon.

The lnventlon ls now illustrated by means of the followlng Examples.
