Description:
LAMELLAR GEL BASED PERSONAL CARE COMPOSITIONS, PROCESS FOR PREPARING THE SAME AND METHOD OF USE THEREO

FIELD OF THE I VE TIO

[0001 ] The present application relates to a personal care composition, and * particularly, to lamellar get based persona! care composition. More specifically, the present application relates to a personal care compositio comprising i) 0 1 wt % to 10 .% of a ierpolymer of vinyl pyrrolidone/acrylic acid/lauryl methacrylate having a relative viscosity of at least 3.3 cp$,· and it) at least one lamellar gel. The present application also relates to methods of using the composition.

BACKGROUND OF THE INVENTION

[0002] Water resistance is sought as one of the most desirable properties in the cosmetic/personal care industry. There have been considerable efforts in the cosmetic/personal care industry to provide personal care/cosmetic products having improved water resistance, particularly lor sunscreen products, skin care products, and other cosmetic products. Water resistance of the skin care products especially of sunscreen products is considered a key element in addition to the other critical elements such as sun protection factor (SPF) and UVA protection it is a well-known approach to use sunscreen products to limit the Ultra Violet (UV) radiation exposure to the skin. It has been observed that most commercially available sanscreen/skin care products suffer from poor water resistance, and the main reason for this poor water resistance of these products is the presence of surfactants. Most of these skin care products are available as emulsions comprising surfactants to reduce the surface tension between the hydrophilic and the hydrophobic ingredients of these products, however, use of such surfactants disadvantageous^ results in decreased water resistance of these products. Due to this decreased water resistance of these products, they tend to remove easily on exposure to water or sweat, tints, necessitating multi ple applications of skin care product Using emulsifiers that form lamellar gels to retain water resistance is the latest trend in manufacturing personal care compositions. Further, these emulsifiers offer multiple benefits to personal care formulations including improved moisturization, seasonably and product stability.

[0003 ] Emulsifiers that form lamellar liquid gels are marketed by several cosmetic ingredient suppliers See, e.g.. International Specialty Products,“Prolipid™ 141 For Skin Caro.;’ pp. 3, 4 (April 1999) (“Prolipid' ); New Paradigm Technologies“Bioba$e™S: Product Information,” Docket No.; 4079PCF p. 1 (Undated) ( t: Biohase ,? ); Seppic,“Montanov; Emulsifiers is Harmony with Nature 55 , p. 1 (July 2000) ( “Monianov”). These lamellar liquid gels serve as barrier and water-retention properties of skin care products.

[0004] United States Patent Publication No 20050238677 discloses a cosmetic or dermatological emulsifier system that forms a multi-lamellar liquid crystalline network comprising (i) a mixture of at least one first sucrose ester and at least one second sucrose ester and (ii) at least one solid fatty alcohol.

[0005] PCX Publication No. 2017 I 97195A1 discloses a whipped o whippable formulation for topical application, such -as, for example, sunscreen. The formulations disclosed have a desired sensory impact to a user.

[0006] in spite of continuous efforts in the personal care/cosmetic industry to develop skin care and/or sunscreen products having improved water resistance properties, there is still a need to envisage skin care compositions comprising improved sensory benefits are with respect to (a) providing protection from the harmful ultraviolet radiations of sun, (b) providing dry and powdery after feel to the skin, (c) providing decreased shine appearance, (d) providing enhanced water resist ance of the sunscreen composition (e ) providing positive appearance, (i) high integrity of ' shape, (g) visual compactness, (h) high spreadabiiity, and/or (i) positive skin feel. Accordingly, it is an objective of the present application to provide a skin care composition having such improved properties.
