FOREWORD
This Indian Standard was adopted bythe Bureau of Indian Standards, after the draft finalized by the Cosmetics
Sectional Committee had been approved bythe Petroleum, Coal and Related Products Division Council.
Cream bleach isatwo component product one containing hydrogen peroxide inacosmetically acceptable form
such ascream, lotion, etc.The second component contains activator essentially inapowder orcream form which
when mixed with acream reacts and Iibrates the necessary quantity ofnascent oxygen for action. Additionally,
itmay contain soothing anti-inflammatory, cooling applications andoptionally itmay contain instruction sheet,
spatula, tray, etc, to facilitate application of product.
Cream bleach and activator are extemporaneously mixed in the proportion advised by‘themanufacturer and
applied. Such application isheld onthe skin/hair foraperiod asspecified andrinsed off, adequate precautions in
respect of product suitability on customer isto betaken.
No stipulation has been made inthis standard regarding composition ofcream bleaches. The manufacturer has a
choice ofusing variety ofrawmaterials andcombination there of.However, itisnecessary thattheraw materials
used are such that inthe concentration inwhich they would bepresent inthe finished cosmetic formulation after
interaction with other raw materials, are free from any harmfid effects. For evaluating the safety of a new
formulation, reference may bemadetoIS4011 :1997 ‘Methodsoftestforsafetyevaluation ofcosmetics (second
revision)’.
A scheme for labelling environment friendly product asknown asECO-Mark was introduced atthe instance of
the Ministry of Environment andForests (MEF), Government ofIndia. TheECO-Mark isbeing administered by
the Bureau of Indian Standards (BIS) under the Bureau of Indian Standards Act, 1986 as per the Resolution
No. 71 dated21 February 1991andNo. 768 dated 24 August 1992published inthe Gazette ofthe Government
of India. For a product to be eligible for marking with ECO logo it shall also carry the Standard Mark of BIS
besides meeting additional environment friendly requirements. .Forthispurpose, theStandard Mark ofBISwould
beasinglemarkbeing acombination ofthe”BISmonogram andtheECOlogo.Requirements forECO,friendliness
wil]be additional, manufacturing units will be free to optfor Standard Mark alone also.

The composition oftheCommittee responsible forthe formulation ofthis standard isgiven inAnnex H,

For the-purpose ofdeciding whether aparticular requirement ofthis standard iscomplied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
IS2:1960 ‘Rules forrounding off numerical values (revise~’. The number ofsignificant places retained inthe
rounded off value should be the same asthat ofthe specified value inthis standard.
