MATERIAL DATA
None assigned. Refer to individual constituents.
INGREDIENT DATA
POLYETHYLENE GLYCOL TRIDECYL ALCOHOL:
No exposure limits set by NOHSC or ACGIH.
SILICA AMORPHOUS:
It is the goal of the ACGIH (and other Agencies) to recommend TLVs (or their
equivalent) for all substances for which there is evidence of health effects at airborne
concentrations encountered in the workplace.
At this time no TLV has been established, even though this material may produce
adverse health effects (as evidenced in animal experiments or clinical experience).
Airborne concentrations must be maintained as low as is practically possible and
occupational exposure must be kept to a minimum.
NOTE: The ACGIH occupational exposure standard for Particles Not Otherwise Specified
(P.N.O.S) does NOT apply.
ALCOHOLS C12-14 ETHOXYLATED:
Sensory irritants are chemicals that produce temporary and undesirable side-effects on
the eyes, nose or throat. Historically occupational exposure standards for these
irritants have been based on observation of workers' responses to various airborne
concentrations. Present day expectations require that nearly every individual should be
protected against even minor sensory irritation and exposure standards are established
using uncertainty factors or safety factors of 5 to 10 or more. On occasion animal no
-observable-effect-levels (NOEL) are used to determine these limits where human results
are unavailable. An additional approach, typically used by the TLV committee (USA) in
determining respiratory standards for this group of chemicals, has been to assign ceiling
values (TLV C) to rapidly acting irritants and to assign short-term exposure limits (TLV
STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints
combine to warrant such a limit. In contrast the MAK Commission (Germany) uses a five
-category system based on intensive odour, local irritation, and elimination half-life.
However this system is being replaced to be consistent with the European Union (EU)
Scientific Committee for Occupational Exposure Limits (SCOEL); this is more closely
allied to that of the USA.
OSHA (USA) concluded that exposure to sensory irritants can:
?cause inflammation
?cause increased susceptibility to other irritants and infectious agents
?lead to permanent injury or dysfunction
?permit greater absorption of hazardous substances and
?acclimate the worker to the irritant warning properties of these substances thus
increasing the risk of overexposure.
PERSONAL PROTECTION
EYE
?Safety glasses with side shields; or as required,
?Chemical goggles.
?Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens or
restrictions on use, should be created for each workplace or task. This should include a
review of lens absorption and adsorption for the class of chemicals in use and an account
of injury experience. Medical and first-aid personnel should be trained in their removal
and suitable equipment should be readily available. In the event of chemical exposure,
begin eye irrigation immediately and remove contact lens as soon as practicable. Lens
should be removed at the first signs of eye redness or irritation - lens should be
removed in a clean environment only after workers have washed hands thoroughly. [CDC
NIOSH Current Intelligence Bulletin 59].

Section 11 - TOXICOLOGICAL INFORMATION
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
Accidental ingestion of the material may be harmful; animal experiments indicate that
ingestion of less than 150 gram may be fatal or may produce serious damage to the health
of the individual.
Ingestion may result in nausea, abdominal irritation, pain and diarrhoea.
Considered an unlikely route of entry in commercial/industrial environments.
Harmful if swallowed.
EYE
Evidence exists, or practical experience predicts, that the material may cause eye
irritation in a substantial number of individuals and/or may produce significant ocular
lesions which are present twenty-four hours or more after instillation into the eye(s) of
experimental animals.
Repeated or prolonged eye contact may cause inflammation characterised by temporary
redness (similar to windburn) of the conjunctiva (conjunctivitis); temporary impairment
of vision and/or other transient eye damage/ulceration may occur.
The liquid may produce eye discomfort causing transient smarting, blinking.
The material may produce severe irritation to the eye causing pronounced inflammation.
Repeated or prolonged exposure to irritants may produce conjunctivitis.
SKIN
The material is not thought to produce adverse health effects or skin irritation
following contact (as classified by EC Directives using animal models). Nevertheless,
good hygiene practice requires that exposure be kept to a minimum and that suitable
gloves be used in an occupational setting.
The material may cause skin irritation after prolonged or repeated exposure and may
produce a contact dermatitis (nonallergic). This form of dermatitis is often
characterised by skin redness (erythema) and swelling epidermis. Histologically there may
be intercellular oedema of the spongy layer (spongiosis) and intracellular oedema of the
epidermis.
INHALED
Evidence shows, or practical experience predicts, that the material produces irritation
of the respiratory system in a substantial number of individuals following inhalation.
Although inhalation is not thought to produce harmful effects (as classified under EC
Directives), the material may still produce health damage, especially where pre-existing
organ (e.g liver, kidney) damage is evident. Present definitions of harmful or toxic
substances are generally confined to doses producing mortality rather than those
producing morbidity (disease, ill-health).
Not normally a hazard due to non-volatile nature of product.

Section 11 - TOXICOLOGICAL INFORMATION
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and by inhalation of
vapours especially at higher temperatures.
Prolonged or continuous skin contact with the liquid may cause defatting with drying,
cracking, irritation and dermatitis following.
As with any chemical product, contact with unprotected bare skin; inhalation of vapour,
mist or dust in work place atmosphere; or ingestion in any form, should be avoided by
observing good occupational work practice.

Section 12 - ECOLOGICAL INFORMATION
Alcohol ethoxylates are generally biodegradable and do not persist for any substantial
period in the environment. They are not usually present a concentrations which might
produce problems. Contamination of natural waters, however, should be avoided.
A EU Risk Assessment Report (RAR) concluded that octyl- and nonyl- phenol ethoxylates are
not readily biodegradable but are inherently biodegradable
As a group, these materials are generally toxic to fish with LC50s ranging, typically,
between 1-6 mg/l.
Of special concern are the following families which are classified as "Environmentally
Hazardous Substances" by either or both the ADR (Accord Europeen Relatif au Transport
International des Merchandises Dangerous par Route) and the IMDG Code (International
Maritime Dangerous Goods Code).
alcohols C 6-17 (secondary) with 3-6 moles of ethoxylation.
alcohols C12-15 with 1-3 moles of ethoxylation (1-6 moles of ethoxylation IMDG)
alcohols C13-15 with 1-6 moles of ethoxylation.
New aquatic data suggests that
alcohols C 8-9 branched with 3-10 moles of ethoxylation
alcohols C 8-9 branched with > 10 moles of ethoxylation should also be classified as
'harmful to the environment"
These alcohols may also be found linked to aromatic structures (in nonylphenol
ethoxylates for example). The current consensus determines that such entities become
Environmental Toxins by association.
Octanol/water partition coefficients cannot easily be determined for surfactants because
one part of the molecule is hydrophilic and the other part is hydrophobic. Consequently
they tend to accumulate at the interface and are not extracted into one or other of the
liquid phases. As a result surfactants are expected to transfer slowly, for example, from
water into the flesh of fish. During this process, readily biodegradable surfactants are
expected to be metabolised rapidly during the process of bioaccumulation. This was
emphasised by the OECD Expert Group stating that chemicals are not to be considered to
show bioaccumulation potential if they are readily biodegradable.
Several anionic and nonionic surfactants have been investigated to evaluate their
potential to bioconcentrate in fish. BCF values (BCF - bioconcentration factor) ranging
from 1 to 350 were found. These are absolute maximum values, resulting from the
radiolabelling technique used. In all these studies, substantial oxidative metabolism was
found resulting in the highest radioactivity in the gall bladder. This indicates liver
transformation of the parent compound and biliary excretion of the metabolised compounds,
so that "real" bioconcentration is overstated. After correction it can be expected that
"real" parent BCF values are one order of magnitude less than those indicated above, i.e.
"real" BCF is <100. Therefore the usual data used for classification by EU directives to
determine whether a substance is "Dangerous to the "Environment" has little bearing on
whether the use of the surfactant is environmentally acceptable.
