Definitions
- the present invention relates to a method for lightening of skin.
- compositions contain two basic ingredients.
- One ingredient is a skin lightening agent.
- a skin lightening agent is a compound which is believed to control dispersion of melanosomes or inhibit tyrosinase.
- Popular skin-lightening agents include niacinamide, carboxylic acids like azelaic acid and kojic acid, plant extracts, hydroquinone etc.
- Niacinamide which is a vitamin B3 compound, is one such widely used skin lightening agent in compositions for topical application.
- the second ingredient in a skin lightening composition is a sunscreen which maintains skin colour against ultra-violet (UV) radiation which are known to cause tanning of skin. These sunscreens act either by absorbing or by blocking the incident UV rays.
- UV ultra-violet
- the sunscreen compounds may be either organic or inorganic in nature; they may be naturally occurring o r could be synthetically prepared, Skin lightening agents along with sunscreen compounds have been combined in skin-lightening compositions to provide synergistic benefits.
- a popular skin lightening composition is based on GB 2 230 186 (Unilever, 1990). This patent discloses a skin lightening composition comprising niacinamide, one or both of a UV-B sunscreen e.g. Parsol MCX and a UV-A sunscreen e.g. Parsol 1789 and a silicone compound. The composition gave enhanced skin lightening over those compositions known at the time this invention was made.
- a two step process one step comprising applying an alcohol on the skin preferably through a wipe and another step comprising applying to the skin a skin lightening agent, provides for enhanced skin lightening as compared to known methods. Good results are obtained irrespective of the order of the sequence.
- WO 01/78678 (Procter & Gamble, 2001) describes a pre-formed device for delivering benefit agents to the skin, hair or nails, the device comprising a solid gel sheet having opposed first and second surfaces wherein the gel sheet comprises one or more gelling agents and at least 10% dermatologically acceptable hydrophilic solvent, characterised in that the first surface is at least partially coated with a discrete coating composition comprising at least one benefit agent for the skin, hair or nails.
- the benefit agent may be niacinamide among a whole host of actives.
- JP 5 317 122 (Piase Anise, 1993) describes a cosmetic/sanitary pad which is used to wipe the perspiration from the skin formed of cotton, non-woven cloth, wet tissue paper and others.
- the cosmetic/sanitary pad is impregnated with cosmetics and disinfectant composed of porous hollow spherical particulates, alcohol, water, allantoin, hydroxy chloride, paraffin, tea extract, L-menthol, perfume and others. Thereby the skin is kept from chapping with a sensation of coolness that is claimed to be long lasting.
- wipes which contain alcohol are also known.
- none of the prior art teach that a two step process, one step involving applying an alcohol and another step comprising applying a skin lightening agent, provides for enhanced skin lightening benefits.
- a method of lightening skin comprising the sequential steps, in any order, of a) applying an alcohol having carbon chain length of 2 to 4, to the skin; and b) applying a skin lightening agent to said skin.
- step of applying the skin lightening agent follows the step of applying the alcohol.
- the invention provides for a two step method of lightening skin.
- This method gives skin lightening which is better than those known presently.
- One step comprises applying to the skin an alcohol.
- the other step comprises applying to the same area of skin a skin-lightening agent. It is thus a sequential method. Either of the steps may be carried out first followed by the other step. However, the preferred sequence is to first apply the alcohol followed by the step of applying the skin lightening agent.
- the second step may be carried out immediately after the first step i.e a few seconds after the first step or a few minutes thereafter. Preferably the second step is carried out from about 2 seconds to about 15 minutes after the first step.
- the alcohol has a carbon chain length of 2 to 4.
- the alcohols are preferably volatile at normal ambient temperatures i.e. in the range of 10 to 50 0 C.
- Suitable alcohols for use in the method of the invention are ethyl alcohol or isopropyl alcohol.
- the alcohol may be formu lated into an a lcohol ic composition. Suita ble forms of the alcohol ic composition are cream, gel, mousse, aerosol spray, stick, powder, or granule.
- the alcohol is impregnated in a porous water-insoluble substrate. It is desirable that the amount of alcohol applied on to the skin is in the range of 5 mg to 50 mg per cm 2 of the skin surface area.
- the alcohol is preferably present from 10% to 95% by weight of said alcoholic composition.
- One preferred method of applying the alcohol on to the skin is from porous water- i nsol uble sheets.
- Such sheets are a lso known as wi pes.
- Suitable material of construction of wipes are woven or non-woven polymeric sheets or made of natural materials like cellulose e.g. cotton or paper, and other natural materials like silk, wool, or laminates of the above. Wipes made of cotton are especially preferred.
- the wipes may be suitably packed to ensure that the alcohol is retained in the wipes during storage and transportation and up until the time of use by the consumer.
- skin benefit agents are delivered to the skin through the alcohol/ alcoholic composition.
- the alcohol/alcoholic composition may have a skin benefit agent dissolved or dispersed in it.
- Useful skin benefit agents are selected from sunscreens, skin lightening agents, vitamins, pharmaceutical actives, penetration enhancers, skin texture improvers, anti-oxidants, anti-inflammatory agents, or emollients.
- the skin benefit agent is preferably present from 0.1% to 10 % by weight of the alcohol. Without wishing to be bound by theory it is believed that the skin benefit agent delivered through the alcohol is better transported by way of higher penetration or by any other mechanism to the target sites on the skin. Further benefits agents which may not be compatible in water based or emulsion based compositions can be delivered through the alcohol by way of the present invention.
- the alcohol may also be applied on to the skin by way of an aerosol spray.
- the mixture of alcohol and pressurised propellants are compressed and filled into a can.
- the can is provided with a dosage valve which may be used to generate a spray for application on to the skin.
- the propellant gases may be liquefied petroleum gases like butane or propane.
- Another suitable way of applying the volatile alcohol on to the skin is by way of a stick as is usually used for application of deodorants.
- the other step of the method of the invention comprises applying a skin lightening agent to the skin.
- the skin lightening agent is preferably delivered to the skin through a skin lightening composition.
- suitable skin lightening agents are vitamin B3 compounds.
- Suitable vitamin B3 compounds are selected from niacin, niacinamide, nicotinyl alcohol, or derivatives or salts thereof.
- the most preferred skin lightening agent is niacinamide.
- the skin lightening agent is preferably incorporated in 0.05% to 10% by weight of the skin lightening composition. More preferred amount is from
- 0.1% to 10%, most preferred amount is from 0.2 % to 5 % by weight of the composition.
- vitamins which act as skin lightening agents can be advantageously included in the skin lightening composition to provide for additional skin lightening effects.
- vitamins include vitamin B6, vitamin C, vitamin A or their precursors. Mixtures of the vitamins can also be employed in the composition of the invention.
- An especially preferred additional vitamin is vitamin B6.
- skin lightening agents useful herein include adapalene, aloe extract, ammonium lactate, arbutin, azelaic acid, butyl hydroxy anisole, butyl hydroxy toluene, citrate esters, deoxyarbutin, 1,3 diphenyl propane derivatives, 2, 5 di hyd roxybenzoic acid a nd its derivatives, 2-(4-acetoxyphenyl)-1 ,3 d itha ne, 2-(4- hydroxyphenyl)-1,3 dithane, ellagic acid, gluco pyranosyl-1-ascorbate, gluconic acid, glycolic acid, green tea extract, 4-Hydroxy-5-methyl-3[2H]-furanone, hydroquinone, 4 hydroxyanisole and its derivatives, 4-hydroxy benzoic acid derivatives, hydroxycaprylic acid, inositol ascorbate, kojic acid, lactic acid, lemon extract
- the skin lightening composition optionally comprises a sunscreen.
- Ultraviolet light is a predominant cause of skin darkening.
- compositions comprising UVA and/or UVB sunscreen are desirable.
- Organic or inorganic sunscreens/sun-blocks may be suitably employed in the composition.
- Preferred sunscreens useful in the present invention are 2-ethylhexyl-p- methoxycinnamate, butylmethoxydibenzoylmethane, 2-hydroxy-4- methoxybenzophenone, octyldimethyl-p-aminobenzoic acid and mixtures thereof.
- Particularly preferred sunscreen is chosen from 2-ethyl hexyl-p-methoxycinnamate, 4,- t-butyl-4'- methoxydibenzoyl-methane or mixtures thereof.
- a safe and effective amount of sunscreen may be incorporated in the compositions used in the present invention.

- a specific portion of the volunteer's forearm was marked out and 3 mg/cm 2 of a commercial skin lightening composition "Fair & Outdoor" containing 1.25 % of a skin lightening active niacinamide was applied five times daily, once every about 1.5 hours.
- a similar specific portion of the volunteer's forearm was marked and washed with a soap once every morning for ten days.
- the washing consisted of rubbing a soap bar 10 times over the marked area followed by rinsing the marked portion free of soap with a large quantity of water to remove all the soap.
- the same skin lightening composition as used in example 1 was applied five times a day, once every about 1.5 hours.
- Example 3 A similar specific portion of the volunteer's forearm was wiped with a muslin cloth soaked with 0.1 ml of a solvent (ethyl alcohol) once a day in the morning. Skin lightening composition as used in example 1 was applied five times a day, once every about 1.5 hours.
- a solvent ethyl alcohol
- the skin lightening score was measured by expert assessors using a colour ruler on a scale of 1 to 10.
- the data in table 1 summarizes the average skin lightening score that is the change in skin colour with respect to the initial skin colour. A more negative score indicates a higher degree of skin lightening.
- a specific portion of the volunteer's dorsal forearm (sun exposed part of the forearm) was marked out and 0.5 grams of a commercial skin lightening composition "Fair & Outdoor" containing 1.25% of a skin lightening active, niacinamide, was applied two times daily, once in the morning and once again after a gap of about four hours.
- a commercial skin lightening composition "Fair & Outdoor” containing 1.25% of a skin lightening active, niacinamide
- a different portion of the volunteer's dorsal forearm was marked out and wiped with a cotton wipe containing 2 ml of ethyl alcohol once a day in the morning.
- a skin lightening composition as used in example 4 was thereafter applied on this marked out portion after 15 minutes.
- the entire procedure of wiping with the alcohol soaked wipe followed by applying the skin lightening composition was repeated on the same day after a gap of four hours.
- a treatment similar to example 5 was carried out on a similar portion of the volunteer's dorsal forearm except that the alcohol contained 3% ascorbic acid.
- the skin lightening score was measured by expert assessors using a colour ruler on a scale of 1 to 10.
- the data in table 2 summaries the average skin lightening score that is the change in skin colour with respect to the initial skin colour at week zero. A more negative score indicates a higher degree of skin lightening.
- Example 7 A specific portion (1 cm 2 area) of the volunteer's forearm was marked out and 3 mg/cm 2 of a commercial skin lightening composition "Fair & Outdoor Multivitamin" containing 1.25% of a skin lightening active niacinamide was applied five times daily, once every about 1.5 hours.
- a skin lightening composition as used in example 7 was applied to a similar specific portion of the volunteer's forearm. Fifteen minutes after this, the same area was wiped with a muslin cloth soaked with 0.1 ml of ethyl alcohol. This procedure was repeated five times a day, every about 1.5 hours.
- the skin lightening scores on the specific portions were measured by expert assessors using a colour ruler on a scale of 1 to 10.
- the data in table 3 summaries the average skin lightening score that is the change in skin colour with respect to the initial skin colour on day zero. A more negative score indicates a higher degree of skin lightening
- a blemish of interest on the cheek of a volunteer was identified.
- the blemish colour was graded using a blemish colour ruler on a scale of 0.5 to 10.
- Example 9 About 0.25 g of "Fair & Outdoor Skin Clarity" a commercial product having 1.25% niacinamide as the skin lightening agent was applied on the blemish of interest. This was done twice a day at an interval of 90 minutes.
- Example 10 The procedure consisted of wiping the blemish of interest with a cotton swab soaked with about two ml ethyl alcohol. A few seconds ( 2 to 5 seconds) after this a skin lightening composition as used in example 12 was applied. This was done twice a day at an interval of 90 minutes.
- the skin lightening score on each of the specific blemishes was measured by expert assessors using a colour ruler on a scale of 0.5 to 10.
- the data in table 4 summarizes the average skin lightening score that is the change in skin colour with respect to the initial skin colour at week zero. A more negative score indicates a higher degree of skin lightening.
