Abstract: The invention relates to extremely mild, concentrated cleansing compositions to create personal care formulations. The mildness of composition towards the skin is due to the synergy of constituent members. More specifically, the compositions comprise of cocamidopropyl PG dimonium chloride phosphate, an alkyl polyglucoside, and sophorolipids to give the superlative performance in terms of foam and lather with extreme gentleness towards the stratum corneum, the uppermost layer of the skin. The concentrated, self-preserving, ultra-mild compositions of the present invention are particularly suitable for cleansing of sensitive skin (babies and sensitive body parts), irritated skin (medically compromised) and very dry skin (senior citizens). Also process for preparing such ultra-mild cleansing composition is provided.

Abstract: The invention discloses ‘powder-to-liquid’ hydratable concentrated solid surfactant compositions and a process of making thereof. The compositions are ‘easy-to-transfer’ and ‘easy-to-hydrate’ and upon dilution with water give ‘ready-to-use’ personal cleansing compositions such as hand-wash, body-wash or shampoo. The ‘powder-to-liquid’ compositions are suitable for classical DIY (do-it-yourself) concept enabling the user to create personal cleansing compositions in the same container as and when needed and significantly reducing plastic consumption by the every-day cleansers. The powder compositions of the present invention are free of thickeners (natural gums or synthetic polymers) and the slimy feel. The compositions are biodegradable and are free from toxic antimicrobial preservatives.

Abstract: Water-in-oil microemulsions containing triglyceride oil for personal care applications are described. The W/O type of microemulsions based on triglyceride oils such as soya oil and sunflower oil are suitable for skin cleansing shower oils. The microemulsions of the patent application allow the use of several mild surfactants, thereby obviating the use of aliphatic amine based anionic surfactants for personal cleansing. The microemulsion based on coconut oil serves like a ‘two-in-one’ formulation for prewash hair conditioning like a typical hair-oil and subsequently like a shampoo for cleansing the hair.

Abstract: The invention discloses persistent antimicrobial protection of hands and/or surfaces of different objects using the hydro-alcoholic gel composition of the present invention. In particular, the invention provides water-resistant sanitizing hydro-alcoholic gel compositions based on ethyl alcohol, silver nanoparticles and fatty acids of Tung seed oil (Aleurites fordii). More particularly, it discloses the compositions that keep the surface sanitized well beyond the instant sanitization provided by volatile ethyl alcohol. The compositions of the present invention have ‘natural origin’ index of minimum 99% as per ISO 16128-2.

Abstract: Disclosed herein are personal care and home care composition comprising the whole of fatty acids (unfractionated) of Tung seed oil (Aleurites fordii, Vernicia fordii (family:Euphorbiaceae) as an antimicrobial preservative. The invention further discloses process of preparation of such compositions having fatty acids of Tung seed oil which are produced by saponification of commercially available Tung oil from seeds of the nuts of Tung tree. The home and personal care compositions comprising ‘whole’ mixture of fatty acids derived from the corresponding triglyceride oil at concentration of 0.5 to 2% w/w of the total composition help preserve the composition without any additional antimicrobial preservatives.

Abstract: A transparent personal cleansing composition for skin and hair care comprises non-ionic and anionic surfactants with hydrophobe of lauryl group in the vegetable oil which exhibit enhanced foaming and lather capacity in comparison to the marketed products. The personal care composition of the present invention avoids harsh or toxic anionic ether sulphate type surfactants, eco-toxic non-ionic fatty alcohol ethoxylates, fatty alkanol amides and a host of other ingredients that are not derived from renewable sources.

Abstract: N-Acyl sarcosines of Formula I, wherein, R?C7 alkyl and C10 alkenyl group with terminal double bond, are described as new antimicrobial preservatives for home and personal care products. Lipidated sarcosines of this patent application preserve creams, lotions, emulsions, solutions or suspensions types of formulations of personal care industry. These are used in: leave-on?? (cold cream, sunscreen) as well as: rinse-off?? (facewash, body wash, shampoo) formulations either alone or in combination with other antimicrobials.

Abstract: Disclosed herein are water-soluble UV absorbing compounds of Formula I with two quaternary ammonium centers, wherein; R is selected from saturated or unsaturated alkyl groups with C12 to C22 carbon atoms and R1 is selected from H or methoxy group. The invention further discloses the synthesis of highly substantive water-soluble UV absorbers containing two quaternary ammonium centers, cinnamidopropyl (2-hydroxypropyl alkyl dimethyl ammonium chloride) dimonium chlorides of Formula I and the compositions containing the same in personal care products.

Abstract: Disclosed herein is a cold-processable antimicrobial composition in non-dusting solid form, free from toxic antimicrobial comprising, a) N-capryloyl glycine (Formula I), b) N-undecylenoyl glycine (Formula II), c) benzoic acid (Formula III) and d) sodium dehydroacetate (Formula IV) for use in personal care and home care products. The invention further discloses a process for preparation of the antimicrobial composition and ease of its incorporation in various personal and home products.

Abstract: The present invention discloses recyclable polymeric catalyst of Formula I, for chlorination of organic acids and alcohols using chlorinating agents such as carbonyl chloride, oxalyl chloride or thionyl chloride, wherein, ‘m’ on the pendent groups on polystyrene backbone can have values from 1 to 5 and R is the alkyl group ranging from C1 to C5.
