Definitions
- the present invention relates to personal wash soap compositions, and in particular to stable personal wash soap compositions incorporating essentially skin lightening benefit agent niacinamide, and also to their process of manuf cture.
- the personal wash soap composition of the invention would enable direct incorporation of skin benefit agent niacinamide in soaps at higher levels to impart better skin lightening properties of the bar, and yet will be stable, maintaining desired consumer attributes of the product even upon long storage in hot and humid conditions .
- sunscreens and skin lightening agents like niacinamide and Parsol are skin benefit agents and incorporated in mutually compatible cosmetic formulations .
- Skin lightening agents such as niacinamide, lactic acid and others are generally unstable in alkaline pH.
- Personal wash formulations are usually soap based, and have an alkaline pH that can prove detrimental to the formulations containing skin lightening agents. Hence, it is a problem to formulate wash-off product comprising these skin-lightening agents.
- the skin lightening-agent is incorporated into the detergent bar at a temperature of 20-
- this formulation was directed to a synergistic soap/detergent formulations which would provide for improved delivery of skin lightening-agents, i.e. niacinamide, onto substrates on which they are applied, thereby obtaining maximum effective value of the benefit agents used in such formulations.
- skin lightening-agents i.e. niacinamide
- sunscreen care protection soap bars are known to develop discoloration upon long time storage in hot, humid and mushy conditions.
- Particularly soaps bases containing unsaturated soaps or fatty acids with 0.1 % to 5 % niacinamide show discoloration in hot, humid and mushy conditions typically in about 30-40 days.
- soaps derived from unsaturated fatty acid e.g. oleic acid
- problems of discoloration and rancidity appear with even 0.5 or lower weight percent niacinamide at ambient temperature.
- soaps derived from unsaturated fatty acids are especially found to be not compatible with the skin benefit agents such as niacinamide, and are usually found to lead to discoloration and loss of consumer attributes of the product.
- iron (Fe) and copper (Cu) impurities in soap formulation catalyze the air oxidation of unsaturated fatty acids moiety
- attempts to control discoloration of such soap formulation in the presence of niacinamide by the use of known ethylenediamine tetraacetic acid (EDTA) /ethylene hydroxy diphosphonate (EHDP) chelating agents of Fe/Cu in soap was found not sufficient to avoid problems of product stability, such as discoloration of niacinamide containing soaps.
- Higher amounts such as up to 0.2 % of EDTA-4Na(35 % solution), 1 % of EHDP (60 % solution) could not avoid the discoloration in soaps having niacinamide.
- soap formulations such as personal wash formulations involving niacinamide which involve soaps derived from espcially unsaturated fatty acids are subject to loss of stability by way of discoloration of the product upon storage, especially in hot, humid & mushy conditions.
- Such discoloration of the product form apart from affecting the constitutional balance of soap formulations and its related loss of benefit properties, also essentially resulted in loss in consumer appeal for the product.
- stability problems in spite of possible formulations involving the active niacinamide in soaps especially for achieving high rate of delivery of the active on skin during use, the wide scale use and application of niacinamide at desired levels in soap formulations is a continuing problem in the art.
- Another object of the present invention is to be able to provide for soap formulations, especially personal wash bars with detergent actives in the range of 15-85% and including soaps derived from unsaturated fatty acid, and skin lightening agent niacinamide which would achieve the desired stability in alkaline pH and high temperatures, and deliver benefit agent to skin through wash-off products without problems of discoloration on storage, especially in hot and humid conditions.
- Yet another object is to be able to provide for a storage stable discoloration-free soap formulations including niacinamide which would achieve the desired storage stability, which cannot be achieved by use of conventional EDTA/EHDP chelating agents used to chelate trace amounts of Fe/Cu present in such soaps.
- Another object of the present invention is to be able to provide for synergistic soaps/detergent formulations which would on the one hand provide for improved delivery of skin lightening-agents onto substrates on which they are applied, thereby obtaining maximum effective value of the benefit agents used in such formulations, and on the other hand avoid problems of storage stability and discoloration on long storage, even under hot and humid conditions.
- Yet another object of the present invention is to be able to provide for soaps/skin care formulations involving skin lightening-agents such as niacinamide and Parsol sunscreens maintaining desired effective levels of niacinamide and the sunscreen for the intended skin protection benefit, and at the same time avoiding the problem of soap discoloration in long storage, especially in hot, humid and mushy conditions.
- skin lightening-agents such as niacinamide and Parsol sunscreens maintaining desired effective levels of niacinamide and the sunscreen for the intended skin protection benefit
- Another object of the present invention is to help enable storage stable incorporation of niacinamide in soaps without the need to avoid unsaturated fatty acid based soaps, and yet achieve the desired storage stability, even in humid and mushy conditions to maintain desired consumer appeal/attributes of the product, and meet the marketing demands of the same.
- a storage stable personal wash/detergent composition comprising 15-85 % detergent active, 0.1-20 % of skin lightening agent selected from niacin, niacinamide, it's precursors and derivatives and 0.02 to 2% of diethylene triamine penta acetic acid (DTPA) .
- DTPA diethylene triamine penta acetic acid
- the above formulation of the invention can include the other usual additives and/or skin/benefit agents used in such personal wash formulations.
- a personal wash detergent composition comprising 15-85 % detergent active, 0.1-20 % of niacinamide 0.02 % to 2 % of diethylene triamine penta acetic acid (DTPA) and 0.2-0.8 % of a chelating agent.
- DTPA diethylene triamine penta acetic acid
- a combination of the DTPA and EHDP in niacinamide containing soap formulations provides for surprisingly improved storage stability even in hot and humid conditions, and provides for making of the soap comprising desired levels of the active niacinamide free of any discoloration problems on storage.
- a personal wash detergent composition comprising 15-85 % detergent active, 0.1-20 % of niacinamide, 0.02 % to 2 % of diethylene triamine penta acetic acid (DTPA) and 0.2-0.8 % of ethylene hydroxy diphosphonate (EHDP) .
- DTPA diethylene triamine penta acetic acid
- EHDP ethylene hydroxy diphosphonate
- the chelating agent used is EHDP.
- a process for manufacture of personal wash detergent composition comprising: providing soap noodles following conventional process and mixing niacinamide with said DTPA and EHDP, the DTPA and EHDP being added before and/or at the time of adding of the niacinamide to thereby obtain the stable soap.
- a storage stable system of enhanced delivery of skin lightening-agent niacinamide for use in detergent/soap formulations wherein the system comprises 15-85 % active, 0.1-20 % skin lightening-agent niacinamide 0.02-2 % DTPA and 0.2-0.8 % EHDP, and optionally other benefit agents/additives, wherein the skin lightening- agent niacinamide is incorporated into the soap at temperature in the range of 20-60°C.
- EDTA/EHDP used to chelate trace amounts of Fe/Cu present in soap cannot achieve, and favour also storage stable incorporation of niacinamide in soap derived from unsaturated fatty acids.
- the selected lightening agents may be selected from niacin, niacinamide, its precursors or derivatives.
- the above skin lightening agents may also be introduced as macro domains during plodding.
- the soap used in the formulation may include unsaturated fatty matter containing soap.
- soap denotes salts of carboxylic fatty acids.
- the soap may be derived from any of the triglycerides conventionally used in soap manufacture - consequently the carboxylate anions in the soap may contain from 8 to 22 carbon atoms.
- the soap may be obtained by saponifying a fat and/or a fattty acid.
- the fats or oils generally used in soap manufacture may be such as tallow, tallow stearines, palm oil, palm stearines, soya bean oil, fish oil, caster oil, rice bran oil, sunflower oil, coconut oil, babassu oil, palm kernel oil, and others.
- the fatty acids are derived from oils/fats selected from coconut, rice bran, ground nut, tallow, palm, palm kernel, cotton seeds, soya bean, castor etc.
- the fatty acid soaps can also be synthetically prepared (e.g. by the oxidation of petroleum or by the Fischer-Tropsch process) . Resin acids, such as those present in tall oil, may be used. Naphthenic acids are also suitable.
- Tallow fatty acids can be derived from various animal sources and generally comprise about 1-8 % myristic acid, about 21-32 % palmitic acid, about 14-31 % stearic acid, about 0-4 % palmitoleic acid, about 36-50 % oleic acid and about 0-5 % linoleic acid.
- a typical distribution is 2.5 % myristic acid, 29 % palmitic acid, 23 % stearic acid, 2 % palmitoleic acid, 41.5 % oleic acid, and 3 % linoleic acid.
- Other similar mixtures, such as those from palm oil and those derived from various animal tallow and lard are also included.
- coconut oil refers to fatty acid mixtures having an approximate carbon chain length distribution of 8 % C8, 7 % CIO, 48 % C12, 17 % C14, 8 % C16, 2 % C18, 7 % oleic and 2 % linoleic acids (the first six fatty acids listed being saturated) .
- Other sources having similar carbon chain length distributions, such as palm kernel oil and babassu kernel oil, are included within the term coconut oil.
- benefit agents such as organic sunscreen, Parsol MCX (a registered trade name of Givaudan Roure and chemically 2-ethyl-hexyl-methoxy cinnamate) , Parsol 1789 (chemically known as butyl methoxy benzoylmethane) may be incorporated.
- Other benefit agents may be selected from moisturisers, emollients, humectants, non-soap surfactants, antimicrobial agents and anti-ageing compounds may also be incorporated.
- the non-soap surfactants may be anionic, nonionic, cationic, amphoteric/zwitterionic or a mixture thereof.
- moistures and humectants examples include polyols, glycerol, cetyl alcohol, carbopol 934, ethoxylated castor oil, paraffin oils, lanolin and its derivatives. Silicone compounds such as silicone surfactants like DC3225C (Dow Corning) and/or silicone emollients, silicone oil (DC 200 Ex-Dow Corning) may also be included. It is preferred to incorporate 1-5 % of the benefit agents at any step prior to step of milling. Alternatively certain of these benefit agents are introduced as macro domains during plodding.
- additives such as one or more water insoluble particulate materials such as talc, kaolin, polysaccharides such as starch or modified starches and cellulose may be incorporated.
- Minor additives such as perfume, color, preservatives, opacifiers and other conventional additives at 1 to 2 % by weight can be incorporated.
- Personal wash products may be formulated in several forms.
- One of the examples of a personal wash product is a soap bar, the process of manufacture of which is described herein.
- the soap may be prepared by neutralising a suitable blend of fatty acids or saponifying a suitable blend of oils, or saponifying a blend of fatty acids and oil.
- the soap is converted into noodles typically having water content in the range of 12-18 %, and to the noodles thus produced the niacinamide as the essential skin benefit agent is added.
- the selective DTPA with EHDP with or without EDTA is mixed with the noodles prior to and/or at the time of the adding to the noodles of the niacinamide. Minors such as perfume, colour, etc. are admixed.
- the skin lightening agents are added in the sigma mixer and mixed with the temperature during the mixing stage being in the range of 20-60°C.
- the mixed soap mass is further milled, plodded and stamped to produce bars .
- Suitable equipment used for the soap making is any equipment that is used in soap/detergent manufacture, and is preferably a high shear kneading mixer.
- the preferred mixers include a ploughshare mixer, mixers with kneading members of Sigma type, multi-wiping overlap, single curve or double arm.
- the double arm kneading mixers can be of overlapping or tangential design.
- the invention can be carried out in a helical screw agitator vessel or multi-head dosing pump/high shear mixer and spray drier combinations, as in conventional processing.
- a conventional soap wash composition was prepared incorporating the skin lightening-agents niacinamide at varying levels of 0.1 - 5 % with the soap including the conventional Fe/Cu chelating agents EDTA at level of 0.02-0.2 % and EHDP at 0.2-1 % .
- the procedure followed is as detailed hereunder.
- Personal wash soap compositions were prepared by the conventional route to obtain 78 % total fatty matter.
- the soap was converted into noodles having water content in the range of 12-18 % and to the noodles thus produced was mixed with niacinamide, EHDP in the level of 0.2-1 % and EDTA in the level of 0.02-0.2 %. Thereafter, niacinamide of varying amounts ranging from 0.1 % to 5 % was added, and mixed in a sigma mixer at a temperature of 40°C. The mixed soap was next milled, plodded and stamped to produce bar.
- EDTA has been used in soap as EDTA-4Na, and the highest allowed limit in soap is 0.02 % (35 % solution) and EHDP limit is 0.8 % (60 % solution) .
- the DTPA limit is 0.5 %
- Soap formulation comprising predominantly sodium oleate soap and niacinamide at 5 % along with 0.04 % DTPA and 0.2 % EHDP (Example 22) or 0.04 % EDTA and 0.2 % EHDP (Example 23) were stored at room temperature for 1 to 3 weeks.
- the discoloration obtained in the absence of DTPA in soap samples and the inventive formulation containing DTPA are presented in Figure 1.
- Example 22 was clear even after storage for 3 weeks (Figure 1A) , but the other control samples of Example 23, showed significant discoloration even after 1 week (Figure IB) which worsened after 2 weeks ( Figure IC) . It is thus possible by way of the present invention to avoid problems of discoloration of soaps, especially personal wash formulations involving soaps derived from unsaturated fatty acid in combination with niacinamide as a skin lightening- agent.
- composition of the invention would therefore on the one hand enable the conventional process of manufacture of soap based wash formulations, and especially enable obtaining compositions/systems for enhanced delivery of skin lightening-agent niacinamide without the problems of discoloration of the product and/or loss of consumer attribute due to presence of niacinamide in such a base formulation.
- composition of the invention would, therefore, favour wider and effective use/application of the skin lightening- agent niacinamide in soaps/personal wash compositions, and avoid limitations of the advantageous use of niacinamide in such cosmetic/personal wash products.
