Description

WO 9~/17880 217 ~ ~ 7 8 PCTIUS94/14289 HIGH LATHERING AND HIGH DEPOSITING SHAMPOOS
WITH MILD SURFACTANT SYSTEM
Technical Field The present invention relates to shampoo cu,,,~uosi~iulls COIIIdill;ll9 functional materials such as cun~itiùr,i, ,~ agents, styling agents or antidandrurf agents. In particular, the present invention relates to mild shampoo cu,,,~,u~i~iu,,~ that are high lathering and provide high deposition of functional materials.
B~.h-,-uu.~d of the Invention Acceptable shampoo cu",,uosi~iu,~s should cleanse the hair and scalp and be safe to the user. However, preferred alldlll~Joos will provide more benefits than simple Cledll'-~eaa and safety. For example, it is desirable to use a mild surfactant system in ~1 Idl I I~JUOS SO that the alldll",oos are non-irritating and gentle to the scalp.
It is also desirable to i~UU~UI ' various functional materials in alld""uoes to provide benefits in addition to cleansing. Examples of such functional materials include ,u, ,dit,u, ,;"~ agents, styling agents, antidandmff agents, and the like. Preferred Slldlll~JUUS will provide high d~Oa;liu,, of the functional materials on the hair and scalp, so that the materials can provide their intended benefits. For instance, co,~iliu,,i,,y agents should be efficiently deposited on the hair during use of the shampoo, so that the agents are not rinsed away and can provide good w,,d,~;ol,;,,~ benefits. Similarly, antidandrurf agents should be efficiently deposited on the scalp to provide good antidandn~rf p~, ru""anc~.
Another important pdldlll_~U. in the formulation of alld"l~uoos is lathering. TKe consuming public often _ ' ~ high lathering with fective deaning, and typically prefers high lathering :,lldlllyUOS to low lathering al ~d""~UUS from an aesthetic ald"dl,u;"L.
Typical mild shampoû formulations utilize high levels of nonionic, cationic and dll~pl ~ ' iu surfactants in the presence of anionic surfactants to obtain good mildness ~.lldld~ rial;~,a. However, the lather volumes of these fomlulations tend to be a~ Ic:dd~ly lower than regular anionic surfactant-based shampoo fommulations.
The advantage of the present invention is the discovery that Slldlll~JUOS ,o"h;.,;"g a particular surfactant system not only provide desirable mildness, but also provide the benefits of high lathering and _ _ _ _ . _ _ _ _ WO 9~/17880 PCT/I~S94/14289 217~278 high depoaiLiu,~ of functional materials. The surfactant system is a Col ~ dliol1 of certain anionic surfactants and polyhydroxy fatty acid amide surfactants in particular amounts and ratios. This invention is described in further detail hereinbelow.
Unless otherwise indicated, all pe, u~"Lay~s and ratios are calculated on a weight basis. Unless otherwise indicated, i"u,~ "l~ are based on the active level and, therefore do not include carriers or by-products that may be included in uu"""t:,uia~ available materials.

(b) from about û.05% to about 25%, by weight, functional materials; and (c) from about 35% to about 95%, by weight, water.
The shampoo uulll~uaiLiùll~ of this invention advantageously provide the desirable cu"lL;,Idliu" of mildness, high lathering, and high dep~ai~iu" of functional materials such as cu, ,ui~iu"i"y agents, styling agents or antidandruff agents.
Detailed D~ of the Invention Surfactant Svstem The shampoo c~lllu~ailiOI1s of the present invention contain a particular surfactant system that has been found to exhibit a desirable C~ illdliu11 of benefits: mildness to the scalp, high lathering, and high depcsiliull of functional materials such as uul~di~iurlil,y agents, styling agents, antidandn~ff agents and the like. The a~ldlllU005 contain from about 5% to about 40% by weight surfactant system, preferably from about 7% to about 35% by weight, and more preferabiy from about 12% to about 2û% by weight. The surfactant system uullll~liae:5. (i) from 8û% to about 99%, by weight of the surfactant system, anionic surfactants which . ,, _, , ,,, ,, _,,, _ _,, WO 9S/17880 ~ 1 7 9 2 7 g PCTIU594/14289 ar~ ~Ikyl ethoxylated sulfates and alkyl suifates in a ratio between about 1:1 and 1:0; and (ii) from about 1% to 20%, by weight of the surfactant system, polyhydroxy fatty acid amide surfactants.
Alkvl Ctl~O~ lalt:d Sulfate and Alkvl Sulfate Surfactants As ",t"~iu"ed above, the surfactant system of the present shampoo ..ulll,uosiLiol~s comprises from 80% to about 99% by weight of the surfactant system, preferably from about 85% to about 95% by weight, anionic surfactants v~hich are alkyl ethoxylated sulfates ("AES") and alkyl sulfates ("AS") in a ratio between about 1:1 and 1:0. The ratio of AES to AS is at least about 1:1, and the anionic surfactants can also be 100%
AES and no AS (ratio of 1:0). The preferred AES:AS ratio is between about 1:1 and about 10:1, more preferably between about 2:1 and about 10:1, and most preferably between about 2:1 and about 6:1.
Alkyl ethoxylated sulfates and alkyl sulfates have the respective formulae (I) RO(C2H4O)XSO3M and (Il) ROSO3M, wherein R is alkyl or alkenyl of from about 9 to about 18 carbon atoms, x is 1 to 12, and M is H
or a soluble salt-forming cation such as ammonium, lh ,old",i"e such as lli~Llldlloldlllille, monovalent metals such as sodium and potassium, or polyvalent metal cations such as magnesium and calcium. The cation M
of the anionic surfactant should be chosen such that the anionic surfactant is water soluble. Solubility will depend upon the particular mixture of anionic surfactants and cations chosen. As an aid to d~.tU.lllillill~ dlJtJlU~JI- ' mixtures of anionic surfactants and cations, the anionic surfactants should be chosen such that the Kram temperature of the surfactants is about 15C or less, preferably about 10C or less, more preferably about 0C or less. It is also preferred that the anionic surfactants be soluble in the present shampoo ~.OIII,UU~i~iU115. Preferred cations for use in this invention are ammonium, sodium and/or magnesium.
The alkyl ull lùxyll.t~d sulfates are typically made as cu, Id~ dliol~
products of ethylene oxide and monohydric alcohols having from about 9 to about 18 carbon atoms. The alcohols can be derived from fats, e.g., coconut oil, palm kemel oil, or tallow, or can be synthetic. Such alcohols are preferably reacted with about 1 to about 10, more preferably from about 1 to about 4, most preferably from about 2 to about 3.5, molar p, u~u, Liulls of ethylene oxide and the resulting mixture of molecular WO 95/17880 2 ~ ~ ~ 2 ~ 8 PCT/US94/14289 species having, for example, an average of 3 moles of ethylene oxide per mole of alcohol, is suifated and neutralized.

A variety of suitable ~,UIIIIII~I~.idl p,ow~ses for manufacturing alkyl sulfates are well known to persons skilled in the field of surfactants.
Suitable alkyl sulfates include, among others, sodium and ammonium salts of lauryl sulfate, coconut alkyl sulfate, and tallow alkyl sulfate. Preferred for use in the present invention are sodium and ammonium salts of lauryl sulfate.

(a) ~u, t:hedli"y the fatty ester to about 1 38C to about 1 70C;
(b) adding the N-alkyl or N-hydroxyalkyl glucamine to the heated fatty acid ester and mixing to the extent needed to form a two-phase iiquid/liquid mixture;
